What are dolphins?
- Dolphins, they swim in the water, but they are not fish! Dolphins are marine mammals that belong to the same group as whales.
- Dolphins can live almost as long as humans, they live between 55 and 60 years.
- The dolphins in the sea are the most well-known, but there are also four species of dolphins living in fresh water.
- They are highly intelligent animals. Like elephants, dolphins can form strong bonds and feel sadness. They are also among the few animals that have passed the mirror test (recognizing themselves in a mirror).
- Not only do dolphins help members of their group when they have problems or are injured, there are also known cases where dolphins helped other animals and even people.
- Dolphin populations are also threatened by human influences all over the world. The biggest problems are that they end up as bycatch in fishing nets and pollution of their habitats.
Where to see dolphins in the wild abroad?
- You can see dolphins in so many places all over the world. Make sure you go on an animal-friendly tour that follows clear guidelines. Here are some well-known places:
- Australia: including Daintree in Queensland and Monkey Mia in Western Australia
- Canada: Vancouver Island
- Ecuador: Galapagos Islands and Isla de la Plata
- Egypt: Marsa Alam
- Indonesia: Bali
- Mozambique: Inhaca, Pemba or Bazaruto
- New Zealand: including Kaikoura
- Portugal: Azores and Madeira
- Norway: Lofoten and Vesterålen
- Seychelles
- Spain: Tenerife
- Sri Lanka: Kalpitiya
- USA: Hawaii, San Juan Islands (Washington)
- South Africa: including Durban
- Freshwater dolphins can be found in the Amazon and Orinoco rivers in South America and in the Ganges, Indus and Irrawaddy river systems.
Where is the best place to swim with dolphins abroad?
- Australia: Bunburry and Ningaloo Reef in Western Australia Monkey Mia
- Bahamas
- Brazil: Fernando De Noronha
- Curacao
- Ecuador: Galapagos Islands
- Egypt: Marsa Alam
- Indonesia: Bali and Raja Ampat
- Mexico: Socorro Island
- New Zealand: Kaikoura
- USA: Hawaii (Kona)
Are dolphins dangerous?
- Dolphins are usually not dangerous, unless you disrespect the space and behavior of the wild animal.
- In that case, dolphins can be a danger. Dolphins are very smart, strong and are quite similar to humans in terms of social behavior. There are even indications that dolphins can commit murder (and not for food, or to defend themselves).
- Fortunately, this does not seem to be aimed at humans. Collisions between humans and wild dolphins certainly do occur, but are usually not that serious. There have been cases of broken ribs and bites by dolphins, among other things.
What are the most dangerous species of dolphins and why?
- Orcas! Yes, orcas are also dolphins. They are the largest dolphin species and can therefore do the most damage, if they wanted to.
- Because in general, wild orcas are not aggressive towards people. However, orcas in captivity have attacked people several times, but what do you expect when you lead such a stressful, unhealthy and boring life.
- There are also known cases of bottlenose dolphins where they felt threatened and showed aggressive behavior.
What to do if you encounter a dolphin in the wild?
- Always keep sufficient distance (about 45 meters) and never approach the dolphin yourself, but let the dolphin come to you.
- Do not touch dolphins, but watch them with your eyes!
- Do not feed them either, no matter how tempting it is, because this can disrupt their natural behavior and affect their health.
What to do when a dolphin attacks you?
- Then try to get away quickly…
Can you volunteer or intern with dolphins?
- You certainly can! Most opportunities are found on research boats, but there are also some dolphin sanctuaries.
- For example, you can help with research (data collection), education and conservation.
What should you do if you are going to work with dolphins during your volunteer work, internship or study.
- Make sure you find a good, ethical organization. Some organizations are more focused on tourism and not good for the animals.
- For example, you can pay attention to whether the animals live in captivity or whether the organization focuses on wild animals, and for example whether they are education-oriented.
Where is the best place to work with dolphins?
- Australia: Bunburry
- Curacao
- Spain: Canary Islands
- Tanzania: Zanzibar
Fish abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
What should you do if you encounter poisonous fish?
- Only a few species of fish are poisonous to the touch. The teeth and spines that fish have are more dangerous.
- However, if you keep your distance, fish, sharks, rays and other small swimming beauties will not cause any problems.
- If you go swimming without anything on your feet, you run the risk of stepping on one of the spiky or even poisonous fish. The chance that you will step on one is not very big, but it certainly happens regularly in a coral-rich environment.
What should you do if you are stung or bitten by a poisonous fish?
- Depending on the species, a quick visit to the doctor is recommended.
- Since this is not always a reasonable alternative, water shoes / flippers / sandals are therefore very important.
- On the Mediterranean and North Sea beaches, many bathers are stung every year by the small weever, which burrows into the sand. This fish can cause you a lot of pain for weeks if you do not quickly put your foot in water hotter than forty degrees after the sting (the proteins in the poison break down).
How dangerous are rays?
- Stingrays can also sting (very) meanly.
- They often lie buried in the bottom waiting for prey, if you then step off your surfboard, the ray can sting out of fear.
- Depending on the exact species and the exact place where you are stung, you may need to see a doctor quickly.
Where are good places to spot fish abroad?
- The best places to spot many different species of fish are the tropical and sub-tropical coral reefs
- These coral reefs offer plenty of space for marine life and juvenile fish, which in turn attracts many larger and super-sized fish
- Many coral reefs and underwater ecosystems are threatened by climate change, over-fertilisation (especially near estuaries), over-fishing and tourist activities. Before booking a trip it can be important to check the current fish and reef status.
- Regions and countries where the value of marine life has long been endorsed, for example through the establishment of nature reserves often have the most beautiful coral reefs to visit
- Check also snorkelling and diving destinations abroad
Jellyfish abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
Jellyfish abroad and while traveling
What are jellyfish?
- Jellyfish are simple, jelly-like marine animals. They often have tentacles, but no brain, heart or other organs like many other animals.
- Jellyfish can swim, but often go with the flow of the current.
- They mainly eat plankton and other small marine animals.
- Jellyfish are very special because of their simple, but effective structure. There is even a jellyfish that is described as immortal - the Turritopsis dohrnii. This jellyfish can revert the cells to a younger form when it is in danger and thus "restart" life.
Where to see jellyfish in the wild abroad?
- Jellyfish are found in all seas and oceans, both on the coast and in the deep sea. Some species that are closely related to jellyfish also occur in fresh water.
- Especially with offshore winds, there is a good chance that jellyfish will come near the coast due to the undercurrent.
How dangerous are jellyfish?
- You don't have to worry about jellyfish coming at you, because they have no interest in people. What usually happens is that someone accidentally swims into one or steps on a dead jellyfish on the beach.
- Some jellyfish are hardly dangerous, other jellyfish can be fatal in severe cases. Fortunately, most jellyfish fall into the first group.
- In most jellyfish, only the tentacles are equipped with stinging stinging cells. These many stinging cells release poison when touched, which usually causes itching and a burning rash.
- The tentacles of a dead jellyfish on the beach can still sting.
What are the most dangerous types of jellyfish and why?
- The 16 species of Irukandji jellyfish are the most poisonous group of jellyfish. With a mostly almost transparent body and a body of only one centimeter in size, these nasty creatures are easy to miss while swimming, snorkeling or diving. The jellyfish group is found around Indonesia, the Philippines and around the Great Barrier Reef.
- Stings from the Irukandji can be fatal and there is no antidote.
- Around Australia you have the box jellyfish (one of the Irukandji jellyfish), also called the Australian sea wasp. A not-so-nice friend with tentacles that can grow to three meters long.
- Watch out for the infamous "Portuguese man-of-war" (found in many places around the world!). An enormous jellyfish-like creature that can cause excruciating pain (go to the hospital!). The fact that this animal is actually a fascinating colony of clones of itself and not a jellyfish, will probably not matter to you after a sting.
What should you do if you are stung by a jellyfish abroad?
- Most jellyfish species only cause somewhat painful stings that can be somewhat combated with vinegar, Azaron or painkillers.
- Rinse the stung area with seawater or hot water. Cold tap water, on the other hand, seems to make the reaction worse.
- Remove the tentacles from your skin as soon as possible after the sting. Scrape the remaining stinging cells from your skin with a credit card, for example, to stop the skin reaction.
- Seek medical attention, especially in areas where dangerous jellyfish species live or when the symptoms are worse than mild pain and red skin.
- There is also water-repellent sunscreen that offers protection against jellyfish stings, even those from the "Portuguese man-of-war".
- The idea that urinating on a jellyfish sting helps is based on a myth, but it can give someone mental peace... the choice is yours.
What diseases can you get from jellyfish?
- Jellyfish are not long-term diseases, but some consequences of jellyfish stings are:
- pain and irritation of the skin.
- swollen welts on the skin.
- a delayed reaction that can cause blisters and a rash.
- less common, but serious is anaphylaxis - a severe allergic reaction.
- Irukandji syndrome when you are stung by certain box jellyfish. You may experience severe pain, muscle cramps and heart problems.
- You may get a wound infection if the sting penetrates the skin.
- If you start sweating profusely, have chest or abdominal pain, or have difficulty breathing, seek immediate medical attention.
Can you volunteer or intern with Jellyfish?
- You might not expect it, but it is possible to do an internship or volunteer work with jellyfish. This involves, for example, research projects where you can help with observations from the beach, or volunteer work in the lab.
- During marine conservation projects you also might encounter jellyfish
Manatees and dugongs abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
What are manatees?
- This special animal group of manatees consists of 3 species of manatees and the dugong (Dugongs).
- Manatees are true herbivores and related to elephants.
- They grow between 2.5 and 4 meters and can weigh up to 1500 kg!
- Unfortunately, the manatee populations are vulnerable to extinction. The greatest dangers to manatees are habitat loss and hunting.
Where do manatees (manatees) live?
- Manatees live in Latin America from Brazil to Florida.
- The West African manatee lives in shallow waters of West Africa.
- Abroad, people often talk about Manatees (or manatí in Spanish)
Where do dugongs live?
- The dugong can be admired in the waters of Northern Australia, Southern Asia, the coastal strips of the Middle East and East Africa.
- The dugong lives on sea grass and only in salt water.
- The dugong is also called the Indian sea cow.
Are manatees dangerous?
- Dugongs are often shy and timid, manatees are more curious. In general, manatees are not dangerous to humans.
- However, humans are dangerous to the manatee. People can cause a lot of stress and with the good memory of manatees, this can linger for a long time.
- In most places in the world, the survival of the manatee is seriously threatened.
What to do if you encounter a manatee in the wild?
- It is always important to keep sufficient distance (50m), especially from a mother with her young.
- Never swim towards them, but let them come to you.
- Stay calm! They won't come to them quickly with a lot of noise, fast movements and throwing water.
- Just watch! Feeding, touching or approaching them in any other way is not good for the animals.
What to do if a manatee attacks you?
- In general, the animals are very calm, but if they do come to you, it is best to move away calmly. Do not make sudden noises or movements.
Can you do volunteer work or an internship with manatees, manatees and dugongs?
- There are a number of organisations in Australia, Costa Rica, Thailand and Belize, among others, that accept volunteers. These are usually research projects or nature conservation organisations.

What are sea turtles?
- Sea turtles are large marine reptiles. They have an impressive shell, a good sense of smell and good underwater vision.
- They live mainly in the water, only the females that lay eggs and the newly hatched baby turtles can be found on land, and very occasionally a turtle that is just sunbathing!
- There are seven main species of marine turtles.
- Flatback Sea Turtle
- Green Sea Turtle
- Hawksbill Sea Turtle
- Kemp's Ridley Sea Turtle / Kemp's sea turtle
- Leatherback Sea Turtle
- Loggerhead sea turtle / Loggerhead sea turtle
- Olive Ridley Sea Turtle / Dwarf Sea Turtle (Warana)
- Turtles can live a long time. It takes 15-30 years for them to reproduce, and then they can live for over a hundred years!
- Unfortunately, sea turtle populations are threatened by hunting for their eggs, meat, skin and shell. They are also often bycatch in fisheries. Climate change also has a strong influence on turtle populations. Because the temperatures in the sand change, the sexes of the baby turtles in the eggs also change.
Where can you encounter sea turtles in the wild when traveling and abroad?
- Sea turtles can be found in almost all oceans, except for the very cold areas and the polar regions.
- They are usually found in the shallow coastal areas around coral reefs, seagrass beds, lagoons and estuaries. There is a lot of food for them here.
- The best places to snorkel or dive with them include:
- Australia: at the Great Barrier Reef or Cook Island
- Costa Rica: at Tortuguero National Park
- Ecuador: at the Galapagos Islands
- Egypt: in the south at Marsa Alam
- Hawaii: a.o. at Maui
- Indonesia: near Bunaken. Pulau Weh or Raja Ampat
- Maldives: at various islands
- Malaysia: at Sipidan or the Perhantians
- Mexico: near Playa del Carmen
- Nicaragua: at the La Flor reserve
- Oman: at the Daymaniyat Islands
Are sea turtles dangerous?
- Although sea turtles can bite, they usually do not bite people. They are gentle creatures that rarely show aggression.
- However, with their exceptionally powerful jaws they can cause damage. Sea turtles do not have teeth, but on the inside of a sea turtle's mouth there are backward-facing cartilaginous barbs.
- They defend themselves when threatened. If you try to pick up a sea turtle, for example, it may bite you in self-defense.
What to do if you encounter a sea turtle while snorkeling?
- If you see a sea turtle in the wild, try not to get too close, do not disturb the turtle and certainly do not try to pick the turtle up.
- During egg laying, you should always stay far away. Do not touch the turtle or stand in its field of vision. This can seriously disrupt the egg laying and have major consequences for the population.
- Especially with baby sea turtles, touching can cause harm. They can become disoriented, they can injure their shell (which is still soft) and eventually they can die.
What to do in case of a turtle bite?
- Wash the wound thoroughly with soap and water to prevent infection.
- Put antiseptic on the wound and keep an eye on it to make sure it doesn't get infected.
What diseases can you get from sea turtles?
- Sea turtles can carry bacteria and diseases that can be harmful to humans.
- Eating sea turtle meat is not safe. Salmonella and chelonitoxism (a type of food poisoning) are a major risk.
Can you do volunteer work or an internship with sea turtles? Or help protect sea turtles?
- You certainly can! There are many great projects to help protect sea turtles.
- For example, you can help with projects that protect the eggs. Here you contribute to the
- protection of eggs by placing fences
- counting and locating eggs
- building breeding sites
- collecting of data, for example by patrolling the beach during the egg-laying period.
- You can also help care for injured turtles.
- Research is another sector that sometimes needs help. For example, there are sometimes projects from universities that need volunteers or interns to carry out research tasks.
- Read more about: Protecting sea turtles: what is it, where can you do it and are you insured?
Why should you protect sea turtles abroad?
- You can have a wonderful time with other passionate individuals.
- All seven species of sea turtles are (seriously) endangered: the Flatback sea turtle, Green sea turtle, Hawksbill sea turtle, Kemp's sea turtle, Leatherback sea turtle, Loggerhead sea turtle and Dwarf sea turtle can use your help.
- Knowledge of a special group of animals.
- Images of sometimes thousands of small turtles.
- What do you need to protect sea turtles abroad?
- A love of nature and animals in general and marine life in particular.
- A flexible sleep schedule.
- Limited sensitivity to less pleasant odors.
- In some cases, a lot of stamina (the nesting sites are sometimes a bit further away on remote beaches).
- If you have experience working with animals or medical care of animals, you can be deployed in more diverse activities of a project.

- Many people have seen the black sea urchin, but did you know that sea urchins come in all shapes and sizes? There are almost 1,000 known species of sea urchins.
- General characteristics are that they are spiny and invertebrate and, of course, live in the sea. They often have hard, coloured spines.
- Sea urchins mainly eat algae, seaweed and other organic material. They are important for healthy coral reefs, because they help maintain the balance between algae and coral.
- Sea urchins can live for hundreds of years!
- In Japan people eat sea urchins. The fleshy sexual organs are often eaten raw. This seafood is also a traditional delicacy in, for example, Italy, New Zealand, Chile and the Philippines.
Where to see sea urchins in the wild abroad?
- Sea urchins can be found in all oceans. Most are found on the coast, but they also occur in the deep sea up to at least 7,000 meters!
- They like to cling to things, such as reefs, rocky shores and other hard objects.
How dangerous are sea urchins?
- The vast majority of sea urchins are not poisonous to humans. However, a sea urchin spine in your foot can be an unpleasant experience.
- If you step on a sea urchin, you should first try to remove the needles completely with tweezers. If the whole thing becomes infected, a visit to the doctor is essential.
- Some sea urchins also have poison in their spines. This can cause symptoms such as nausea, vomiting and difficulty breathing, but this is very rare.
- Wearing water shoes can prevent a lot of disaster.
What are the most dangerous types of sea urchins and why?
- It looks beautiful, but the Flower Urchin is also the most poisonous sea urchin. It is found in coral reefs, between sea grass and on rocky and sandy bottoms, especially in the tropical Indo-West Pacific Ocean.
What to do if you encounter a sea urchin in the wild?
- It is best to maintain sufficient distance!
- Sea urchins are slow and don't go after you, but accidentally stepping on it can be a nasty experience
Which diseases can humans get from a sea urchin?
- The most common risk is that you get an infection at the place where the needles have entered your body.
- You can also suffer from a feeling of weakness, shock, pain in your muscles and even in exceptional cases, paralysis.
- In most cases, the pain goes away after a few days. Are you worried? Then it is best to visit a pharmacy or doctor.
What should you do if you are stung by a sea urchin?
- First try to remove the needles. Do this very carefully, because they break off very easily. Then wash the area thoroughly with soap and water.
- If you still feel pain after several days, if it seems to be getting infected, if you have weakness or pain in your muscles, paralysis or extreme fatigue, then you should definitely see a doctor.

What are seals?
- A seal is a marine mammal that belongs to the carnivores. Seals have fin-like forelimbs with which they propel themselves in the water, somewhat less flexible hind legs, a soft coat and an excellent ability to dive. Seals do not have protruding auricles (they do have ears...).
- There are different types of seals that vary in size and color. Most species have a somewhat spotted coat.
- Seals usually eat fish, shellfish and other marine animals.
- Seals are often found in somewhat colder water, but they can also survive well in warmer temperatures.
- Seals are also called sea seals
- Elephant seals, leopard seals and the hooded seal are also species within the seal family.
What is a sea lion?
- A sea lion is also a marine mammal that belongs to the carnivores. Sea lions are somewhat larger, slimmer, faster, noisier and somewhat more aggressive than seals. Sea lions also have external ears. The sea lion is a social animal that often lives in large colonies.
- Sea lions, together with the fur seals, form the group of eared seals.
- Sea lions and fur seals live in the United States, the South American coast, Australia, New Zealand, North-East Asia and the waters around Antarctica.
Where can you see seals and sea lions when traveling?
- Argentina: large colonies of sea lions can be seen in Patagonia.
- Australia: swimming and snorkeling with the sea lions at, for example, Hamelin Bay or Ningaloo Reef. (Western Australia)
- Greenland and Spitsbergen: walruses, hooded seals and seals
- Ecuador: on the Galapagos Islands you will find the fur seal that you can see up close
- Mexico: in Baja California you can swim with sea lions
- New Zealand: sea lions at Kaikoura on the South Island
- Namibia: ...beaches full of sea lions
- Spain: on the Canary Islands La Graciosa and El Hierro you can see sea lions well
- United States: along the Californian coast
- South Africa: the coastal strip near Cape Town
- In the Netherlands and Belgium you can mainly encounter the common seal and the gray seal on the beach
Are seals dangerous?
- In general, seals are not dangerous to people, and rather shy and very calm. While surfing you can sometimes come across a sudden, curious seal, but it will quickly disappear when you try to approach it.
- If they feel threatened and you are close by, they can bite viciously. There are also known cases of seals and sea lions pulling people and dogs into the water. This is often due to confusion because people feed the animals.
- Sick and injured seals can also react unpredictably.
Are sea lions dangerous?
- A sea lion is generally not dangerous to people.
- In places where sea lions are often fed by tourists or local fishermen, they can sometimes become a bit pushy.
- If a sea lion is threatened, or if you enter their territory, you should be careful. Sea lions are quite large and powerful, with their length of 2 to 3 meters.
- They can behave aggressively if they feel unsafe or if they want to protect their young.
What to do if you encounter a seal or sea lion in the wild?
- The best thing, as with all other animals, is to keep your distance (20-30m) and not to interact.
- Never approach the animals yourself. You can wait and see if they come to you (but don't feed them!). Enjoy the moment and relax, stay calm and move slowly so you don't scare them away.
- You sometimes see videos of people swimming with seals. It looks fun, but they can suddenly bite and then you have a big wound.
- If you have a dog with you, make sure it is on a leash. That is better for the dog and for the seal or sea lion.
- Make sure the escape route for the animal (the open sea) is always clear. Never surround an animal.
What to do if a seal or sea lion attacks you?
- Try not to get pulled under and get out of the water if you can, that's what seals are good at and where it gets really dangerous.
- If you get pulled in, try kicking them on the head. Hopefully they'll let go. Or call your friends to hold on.
What to do if you get bitten by a seal or sea lion?
- Wash the wound and get medical help.
What diseases can you get from seals and sea lions?
- There are several diseases that you can get from the saliva, feces or a bite from seals and sea lions:
- Toxoplasmosis
- Tuberculosis.
- Brucella
- Q fever - Rare, but possible by inhaling contaminated dust from feces.
- Spekkfinger - an infection that can occur after a bite or scratch.
Can you volunteer or intern with seals and sea lions?
- There are several organizations around the world that focus on sea lions and seals. They are often research organizations or non-profits that take in injured or sick animals. Sometimes they are also temporary projects that you can contribute to.
- So you can do an internship or volunteer work in the research corner, animal care or nature conservation projects.
What should you do if you are going to work with seals or sea lions during your volunteer work, internship or study?
- Most sanctuaries avoid human contact to keep the animals wild. Therefore, it is unlikely that you will have direct contact with the animals, unless they are babies that need to be fed or you have been specifically trained for this.
- Follow the instructions and safety training protocols.
- Avoid unnecessary actions.
What are the best places to work with seals and sea lions?
- Popular countries are the Netherlands with several sanctuaries, Ireland, South Africa, New Zealand and Australia.

- Sharks are on average 1 to 2 metres long. The smallest sharks are less than 20 cm long, the largest sharks can be longer than 12 metres.
- Sharks are found worldwide in all seas and oceans, except at the North and South Poles.
- Sharks have been on earth for hundreds of millions of years. Today there are more than 400 species of sharks.
What is a great white shark?
- A white shark can be recognised by a black or dark grey upper side and a white underside.
- There are black spots on the underside of the pectoral fins and a conspicuous black spot at the attachment to the body. They prefer cold waters near the coast, but can also be found at depths of over a thousand metres.
- They are very social animals and often swim in groups of ten or more sharks.
- The white shark is semi-warm-blooded, which means that it can swim very fast, but also that it has poor endurance.
- In response to this, the white shark uses different swimming and behavioural patterns to investigate its potential prey.
Where can you see sharks from a boat?
- South Africa: at Cape Town and Gansbaai you can take tours to see the great white shark (from a boat or in a cage).

How dangerous is the great white shark?
- The great white shark is known as one of the most dangerous shark species. The white shark generally bites people only because it is curious and explores terrain in this way. Unfortunately, this method of research sometimes leads to a fatal end for the research subject…
- The prey they prefer depends on several things, such as the season and their size. Small white sharks mainly feed on fish, while the larger ones can devour a seal or even a small whale.
When does a shark become dangerous and should you be careful?
- If a shark rolls its eyes, the shark follows an object with its eyes, without moving its head or body; you have been spotted!
- If you notice that a shark lowers its pectoral fins or opens its mouth without protruding its front jaw and holds this position for a fraction or several seconds, it should be considered dangerous.
- If the shark protrudes its upper jaw, the shark makes a biting movement; If you are bleeding yourself, you don't necessarily have to worry anymore, sharks don't react to human blood or your scent.
- Divers who are spearfishing and have struggling and bleeding fish on their spears are at greater risk.
- What should you do if you are going to swim or dive in an area where sharks are present?
- Find out about the type of sharks and the behavior of the sharks in the area. Most locals can tell you in which season and which sharks you should watch out for.
- Do not swim or dive in an area where the river flows out, that is the shark's hunting ground.
- Dive, swim and surf in groups as much as possible.
- Wear dark clothing, and no white, yellow or neon swimwear, this is more noticeable to sharks because of the way they look.
- Do take a snorkel or diving mask with you and preferably fins as well.
- Stay alert, show that you can see everything. Sharks wait until they see a weak spot in an animal before they approach, and are slower to approach if they think the other is alert or also a predator.
- Realize that there are thousands of sharks per day that come near a diver, surfer or swimmer every day, without giving them a second glance. However, if you do come across that one shark that does seem interested in you, stick to the most important rules of the game.
- Most rules apply more to divers and snorkelers than to swimmers and surfers.
What should you do if you encounter a shark in the water?
- Remain as calm as possible and behave as much as possible like a predator and not like a prey.
- Try to hide your fear, sharks can feel fear and prey can feel fear.
- Keep looking at the shark. As is often the case with other predators, sharks then assume that you are probably a predator too. Only other predators dare to enter into a confrontation. So keep looking at the shark with the same stern look you put on when you go to your mother-in-law.
- Do not hit the shark when it comes close, do not splash, only weak and injured animals do that.
- Do not chase a shark or swim towards a shark.
- Do not try to swim away quickly, but swim calmly backwards towards a reef or boat. Swim as regularly as possible.
- Stay as vertical as possible in the water.
- Keep space between you and the shark, use your fins to 'push' water towards the shark, this can cause them to turn away. If you want to push a shark away, do so with your fin, camera or an aluminum shark stick.
Where can you work, volunteer or do an internship with sharks?
- Volunteer or Internship with Great White Shark: South Africa (Cape Town)
- Volunteer or Internship with Whale Shark: Belize, England, Indonesia (Raja Ampa), Madagascar, Mozambique, and Tanzania (Mafia Island)
- Volunteer or Internship with Reef Sharks: Malaysia (Perhentians)
- Other shark conservation projects can be found in the Seychelles and Fiji
- During projects that focus on whales and sea turtles, you often have the chance to see sharks or help protect them.
Starfish abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
What are starfish?
- Starfish are marine invertebrates, animals without a backbone just like sea urchins and sea cucumbers.
- So they are not fish, despite the fact that they are called starfish in English.
- Starfish have no brain and not even blood. They eat by filtering seawater with their nervous system.
- Starfish can live up to 35 years! So do not disturb them, so that they can reach their old age.
- The 5-armed stars are the most well-known, but some starfish grow up to 40 arms!
- If a piece of their arm breaks off, they can simply grow it back themselves. But this does take a lot of time and energy.
Where can you encounter starfish in the wild while travelling and abroad?
- The more than 1,900 species of starfish are found in seas and oceans worldwide.
- At low tide you can often find starfish on rocky coasts in tidal pools
- With strong wind or heatwaves starfish are sometimes found washed ashore in large numbers
Are starfish dangerous?
- Starfish are rarely dangerous if you step on them or if you touch them. Exceptions are mainly the specimens with large spines, such as the crown-of-thorns.
- Some starfish species are poisonous if you want to eat them. Since starfish are hard and calcareous and have no fleshy parts, there are only a few cultures in the world that include starfish in their diet.
What to do if you encounter a starfish in the wild?
- Above all, let the starfish continue to live in peace, observe it and go your own way.
Where can you work with starfish and protect coral reefs?
- Some starfish species are seen as pests, especially on coral reefs. Large groups of starfish can completely destroy a coral reef and thus threaten the local ecosystem.
- The North Atlantic starfish and the crown-of-thorns are, for example, being combated by conservationists on the Australian great barrier reef.
- Removing large numbers of starfish is very labor-intensive and can only be done by divers. Volunteers are often used for this.
Walruses abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
What are walruses?
- A walrus is related to the seal and sea lion and is recognizable by its large, downward-facing tusks.
- A walrus can grow to over 3 meters in length, making it one of the largest marine predators.
- Walruses spend a lot of time on the ice or on beaches and rocky shores, where they rest, feed and even socialize.
Where to see a walrus in the wild abroad?
- If you want to see a walrus in the wild, you can travel to the Arctic regions of Alaska or Canada, for example, where ecotourism and walrus expeditions sometimes offer opportunities to spot walruses.
- Russia: Northern Russia (Pacific walrus) and on the northern coast of Siberia (Siberian walrus)
- Greenland: West coast (Atlantic walrus)
- Canada: on the Arctic islands (Atlantic walrus)
- Norway: Spitsbergen (Atlantic walrus)
- United States: thousands of walruses gather in Northern Alaska in the summer (Pacific walrus)
Is a walrus dangerous?
- It is best not to get too close to a walrus in the wild.
- A walrus is normally not dangerous. They are marine predators that might look dangerous, but they are actually bad hunters and mainly eat shellfish.
- A walrus can be dangerous, however, if it feels threatened or is protecting its young.
- They remain strong animals that can also react aggressively. With their large tusks, they are able to defend themselves well and injure you. Walruses have also attacked and killed people in the past who came too close in a kayak.
What to do if you encounter a walrus in the wild?
- So stay away if you encounter a walrus and stay calm. Try not to talk or make any noise. They can be quite unpredictable and territorial.
- Walruses react strongly to sounds, smells and things they see. This usually causes them to flee. Try not to disturb them, because a flight response can cause young to be trampled.
- Smoking can also cause disturbance.
What to do if a walrus attacks you?
- While it is rare, walruses mainly attack people in boats. An attack can also occur on land/ice.
- If a walrus attacks you, you better get away. They are very strong, so there is not much you can do.
Can you do volunteer work or an internship with walruses?
- You can, but there is not much choice of projects. One of the most famous projects is “walrus detectives”, where people can look at satellite images to map walruses. Everyone around the world can participate.
Whales abroad and while traveling: are they dangerous, where do you encounter them, where can you see them?
What are whales?
- When people go whale watching in nature, they usually mean the so-called baleen whales (from fin whale, the 'pirates', to the pygmy whale).
- Well-known whale species are the Blue whale, the Northern and Southern Right whale, the Greenland whale and the Humpback whale.
- Whales often live in the open sea, because they have baleen instead of teeth, they only eat plankton and small crustaceans.
- The whale shark is not a whale but a shark, which resembles a baleen whale in its way of eating.
- The different whale species often live in the open sea, but in certain periods they come closer to the coast or have their young in shallow coastal zones. These are the moments when many travellers try to spot a whale from the coast or from a boat.
Where can you encounter whales in the wild while travelling and abroad?
Argentina
- Puerto Madryn: September and October in particular are fantastic for seeing Southern Right Whales.

Sri Lanka
- In the south of Sri Lanka you can spot blue whales, humpback whales and sperm whales in early spring.
South Africa
- Western Cape: at Hermanius is a humpback paradise where you can see humpback whales from May to December.
Are whales dangerous?
- Fortunately, there are few accidents with whales, but whales can be dangerous.
- This is especially the case if you get close to the whale or its calf and it does not feel like it or feels threatened. They can then hit with their gigantic tail, or even bite.
- There is also a small chance that you will get diseases and parasites if you come into contact with whale saliva or urine.
- Conversely, people are also a danger to whales. For example, the chemicals in sunscreen are bad for whales and other marine life. Disruption by overly enthusiastic tour guides still occurs regularly
Where can you work, volunteer or intern with whales abroad?
- Counting, observing and protecting whales is a possibility to work with whales as an intern researcher or volunteer abroad.
- There are opportunities in Canada, Australia and Scotland, among others.

- Sharks
- Jellyfish
- All kinds of fish
- Whales
- Sea urchins
- Manatees

Are freshwater and marine animals dangerous?
- Marine and freshwater animals can be extremely dangerous, and even deadly.
- Some animals only cause some discomfort or pain, such as certain jellyfish, sea urchins or some fish.
- Other animals are mainly dangerous because of their (biting) power, such as crocodiles, hippos and sharks.
- And in some species, poison or electricity is a major problem.
What to do if you encounter freshwater and marine animals in the wild?
- As with any other animal, it is important to keep your distance and not to provoke.
- The best thing to do varies greatly per animal, see the specific animal pages for this.
- Sometimes you don't see animals, especially in water. It can help to be aware of the risks you run in the area where you are.
What to do when an animal attacks you in the water?
- Check the specific animal pages to get an answer.
What to do in case of a bite or scratch by freshwater and marine animals?
- This also varies greatly per animal, but in general you should get out of the water as soon as possible and seek medical help. It is even better if you can find a lifeguard right away. They usually know what to do.
- Sometimes you have to wash the wound, or if it bleeds badly, apply pressure to the wound. In other cases you have to use hot water or apply pressure bandages.
What are the most dangerous freshwater and marine animal species and why?
- Some of the most dangerous marine animals are:
- Australian sea wasp (box jellyfish)
- White shark
- Stonefish
- Sea snake
- Lionfish
- Blue-ringed octopus
- Portuguese man-of-war
- cone snail (yes, a snail. So don't pick up that beautiful shell in Australia, because it could mean the end!)
- In freshwater you mainly encounter strong animals such as:
- Bull shark - which sometimes swims into river areas from the sea
- Electric eel - yes, really shocking
- Goliath tigerfish. This African fish can grow to 70 kg!
- Nile crocodile
- Hippopotamus
- Piranha
- Saltwater crocodile
Which diseases can humans get from freshwater and marine animals?
- There are all kinds of diseases that you can get from animals in fresh water and sea water. Bacterial infections, parasites, poison and even death.
Can you volunteer or intern with freshwater and marine animals?
- There are opportunities all over the world to do volunteer work or an internship with water animals. Mostly it concerns animals that live in the sea, but there are also projects with freshwater animals here and there.
- Popular projects are often projects focused on dolphins, sea turtles, whales, or coral reefs.
What should you do if you are going to work with freshwater and marine animals during your volunteer work, internship or study.
- Read up on the animal species you are going to work with.
- Ask for safety protocols, because working on/in the water is very different from working on land.
- Always follow the instructions of the organization and supervisors carefully.
- Respect the animal and the ecosystem.
