Seychelles, Venomous Snakes, Poisonous Spiders, Sharks & Jellyfish


Poisonous snakes, venomous spiders and man eating sharks are waiting for the unsuspecting tourist who choose a vacation in the Seychelles Islands. Stinging jellyfish, sea snakes, and all manners of creatures can turn vacations in the Seychelles into a nightmare.

Fatal bites have taken the lives of bathers as occasionally, a rogue shark will hunt the waters waiting for an unsuspecting swimmer.

Tropical jellyfish can kill a human in minutes, whilst some snake bites can cause a long and painful death. Life saving surgery should not be part of a cheap package vacation, nor should losing a loved one.

On August 16th 2011, a honeymoon was cut short when a man went into the sea for a swim and was killed by a shark. Several weeks earlier a French man had been killed by a shark attack in the same area. The authorities kept the news down on the first shark attack to protect the tourism industry.

Welcome to the wonderful, beautiful, yet sometimes deadly, Seychelles, enjoy your vacation.

Boomslang Snake

The Seychelles comprise of 115 separate islands off the Southeast coast of Africa. As with all sub tropical places, they are prone to a much higher population of deadly insects and animals.

The Boomslang Snake is a small, yet formidable creature. It can open its' mouth to a 90 degree angle and can deliver a powerful potent injection of venom from its fangs at the rear of its' mouth. Meeting this snake whilst on vacation in the Seychelles is a scary thought.


The venom produced by the Boom-slang snake is hemotoxin, which prevents blood clotting. This may cause a bitten victim to die from internal bleeding as the venom spreads through the blood stream.

Other possibilities and symptoms include nausea, sleepiness and permanent mental disorders. The venom is slow activating which does give time for the anti venom to be given, but then some people underestimate the potential of the bite unti it is to late.

The Boomslang venomous snake is a tree dwelling snake and has often been seen hanging down from trees and being inadvertently walked into. It is a shy snake but will retaliate if being threatened or attacked.

Do not approach this snake if it is seen, use the zoom lens on the camera to take any pictures, do not try to get close, your vacation and life depends on it.


Sea Snakes

Sea snakes can be found all over the globe in warm waters, including the Seychelles. They are mainly very colorful and can grow to nearly four feet in length. The initial bite from this snake may not even be noticed by the swimmer, but the teeth can remain in the bite wound.

There is usually little or no swelling around the wound which makes a bather believe that they have not been bitten. Occasionally a fatal deception.

Early symptoms of a sea snake bite will include a dry tongue, headaches, sweating, and vomiting. Within thirty minutes the victim will feel tenderness in all the muscles of the body and a constant aching.

Soon, paralysis of muscles will occur in respiration and swallowing, this alone can cause death through asphyxiation. The urine may turn brown or even black and lead to acute renal failure. Within six hours the onset of a cardiac arrest, then death.

Sea snakes are dangerous and are potentially a life taking creature. Avoid at all costs. If a sea snake is seen, do not swim in the water, and take heed of any local warnings which have been posted to warn of danger. Vacations or holidays to the Seychelles are out of this world for many travellers, always be alert and ready to run for your life just in case.

They are everywhere. Spiders have invaded these beautiful islands and have never left. They are not venomous, but there may be the occasional immigrant spider waiting to nip an unsuspecting traveller. When booking places to stay in the Seychelles, it may be advisable to opt for an apartment off of the ground floor.

The Palm Spider is quite a large spider and can frighten many people. The long legs ensures that this spider can run when it needs to. Different islands in the Seychelles are home to different types of spider. Be prepared and take a spider repellent away with you before leaving home for your vacation.


There are several species of scorpions living on some of the Seychelles Islands. Some of the species, including the "Chiromachus Ochropus" are protected by law. Although these little beasts do not kill humans, usually, they can deliver a venomous sting from their tail or a nasty nip from their front claws.

The sting is easily treated with anti histamenes and a lay down for a couple of hours. But to be sure, seek medical attention just in case if stung.

Beautiful but Deadly

Box Jellyfish

Also known as the "Sea Wasp" is mainly known to fester in the warm waters off of the Australian coast. But as it is usually propelled by the wind, this venomous creature has been found around Africa, Florida and Japan.

The box jellyfish sting is lethal to nearly all sea animals and humans. People on vacation or holiday in the Seychelles are to avoid the beaches at all costs if told to do so by local life guards or police.

These sea creatures have been known to move up to six meters per minute. There are several different species of which some only give minor stings, whereas others have been labelled as one of the most venomous creatures in the world.

Approximately 20-40 people in the Philippines alone, die each year from Box jellyfish stings. In Hawaii, approximately 7-10 days after a full moon, lifeguards have closed beaches because the influx of box jellyfish is so enormous.

Death By Jellyfish

Death By Jellyfish

Children are more at risk from this jellyfish because of their lower body mass and this has resulted in more child deaths in recent years.

A ten year old girl survived multiple box jellyfish stings in 2010 and has been praised as a medical miracle. There can be as many as fifteen tentacles and each one can be up to three meters in length on each jellyfish.

The initial sting may not be felt, but the tentacles will continue to pump venom into a victim if the jellyfish is dead or the tentacle has been removed from its' body.

Vinegar will prevent more toxins from being pumped into the victim, but will not stop or ease the pain. Once stung, cardiac arrest can happen quite quickly. Seek medical attention immediately if an encounter with a box jellyfish has happened. Do not pee on the wound, it has never been proven to work.

NB: Vacations or holidays in the Seychelles are enjoyed by millions of people every year without incident.


Tiger Shark

Shark attacks are usually a rarity in the Seychelles, but as every knows with recent press reports, it does happen. The Tiger Shark has been known as a man killer and does frequent the water around the Seychelles Islands. The Tiger Shark can reach lengths of 20 feet ( 6m ) and is second on the list of sharks responsible for attacks on humans after the Great White Shark.

This species of shark can be found in shallow waters along the coast of warm, tropical climates. Between 1959 and 1976, nearly 5000 tiger sharks were systematically culled to protect the tourism industry, but the attacks on man did not decrease. The Tiger Shark will eat anything. It eats turtles, dolphins, humans, car tyres, number plates, and even whales.

Tiger Sharks were said to be responsible for some of the deaths of the crew of the USS Indianapolis during World War II. After being torpedoed, 900 crew went into the water, only 317 came out. The rest were eaten and chewed on by Thresher Sharks and Tiger Sharks.

Feeding sharks whilst scuba diving has been part of the Seychelles tourist industry for years. It has been said that feeding wild sharks this way, has attracted many more sharks to the area including rogue sharks responsible for the attacks on humans. Many people on vacation in the Seychelles have now stopped this type of tourism.

Bull Sharks

Bull Sharks have also been known to attack and kill humans every year. Shark attacks on man have increased every decade since records were started in 1900. During 1900 there were only 20 recorded unprovoked attacks on humans worldwide. During the 1940s, there were 100, and by the 1990s they were over 500 annual attacks on humans. By the year 2000, there were over 650 shark attacks ever year, most on people whilst on a vacation.

Bull Shark

Most of the shark attacks have been blamed on the Great White Shark, but the Bull Shark has also had its' fair share of human fatalities. This shark is common in the Seychelles although not yet blamed for many shark attacks, but has killed on many occasions.

The Bull Shark is known for its aggression and unpredictable behaviour and can usually be 11 feet long. This species of shark is found in shallow waters and is very territorial, and will attack any animal that enters its domain, making this shark very dangerous to humans. They can accelerate rapidly and can catch nearly every aquatic mammal and have a bite force of 1,250 lbs per square inch.

Please Note

The Seychelles are not dangerous. Some of the land dwelling dangers have been brought over in containers and are not native to the islands.

What crap! This snake is native & restricted to Sub Saharan Africa !

Who has paid this bull shitter. We are from Seychelles have lived here for generations! U can die by crossing a road anywhere in the world & if your are going into the wild , land or sea surely u must be aware of the danger as u wld every time u get out your car or house, where ever u come from!

Bernadette on January 10, 2018:

I live in Seychelles, in a tropical jungle, never seen a snake evn though I would have love to see one, swim everyday and have never encountered a shark.

We do have garden spiders which are scared of us humans and very shy too. I spend most of my day working in the garden. We do have centipedes that crawls out at night, just dont walk barefoot on the grass and keep your doors closed at night as bugs tend to follow the light.

In my opinion as a native I would say my island is very safe, I work in the tourism industry and have only had one reported case of centipede bite on our guest, which was treated with ice pack.

andre on September 07, 2016:

hehehe! well, I don't know who is sponsoring this person to write such articles..but I HAVE TO SAY..He had a Gps break down and went to another planet thinking he was in the Seychelles....I've live there for

44yrs and never once experience what he is saying despite being all

over the place as thousand times..The only close truth is 2 shark attacks in 200 yrs of history...fix your Gps and come back dear I WILL BE YOUR GUIDE AROUND.

"Poisonous snakes, venomous spiders and man eating sharks are waiting for the unsuspecting tourist who choose a vacation in the Seychelles Islands"....I have lived in Seychelles for three years now, and this is the most ill-informed article I have read about Seychelles....what nonsense!

Kristen Howe from Northeast Ohio on February 26, 2015:

I never been to Seychelles before. But your list of the poisonous animals you can find there was fascinating. Thanks for sharing. Voted up!

billericky (author) from Plymouth on April 24, 2014:

As you said, the boomslang snake is on some of the islands of the Seychelles, which is what I said. I also stated about shark attacks, which you also said has happened, albeit within two weeks of eaach other.

It may be a safe place, but tell that to the two swimmers who were killed by the sharks....

Any country can be safe if you return from it not injured, its only when you get injured or killed that it then becomes 'unsafe', and it does happen. This article is written only as a guide as to the worst case scenario as to dangers that DO exist, as you also pointed out.

So why say Crappp?

Glen on April 24, 2014:

OMG what a load of Crappp, The biggest risk Seychelles has to offer is leptospirosis. That boomslang snake does NOT live in Seychelles, there are no venomous snakes in seychelles.. not on the inhabited islands anyway. perhaps on some of the small islands near Madagascar? even then i doubt it. its not listed in my book on wildlife in seychelles. there is ONLY 1 fatal critter there, that's the cone fish with the poisonous barb. Sharks also i guess, but even then there are only 2 recorded cases of fatalities, and that was recently within 2 weeks of each other. i think the last recorded case of an attack was 10 years prior, and never a fatal one.

My wife is from Seychelles, I have spent a lot of time there and plan to live there at least half the time. i feel MUCH safer there than here in Australia! and i dont feel unsafe here... Id go so far as to say its safer there than anywhere else in the world i can think of!

gretel on July 24, 2013:

Oh! People. I grew up there. I am from there but moved to the U.S. As a child, I lived near the beach, swam all day, walked in the woods, climbed trees but I never saw a deadly snake as in the picture, never heard of a deadly snake, never heard of a shark attack until 2 years ago. My brother was actually on vacation and the was swimming next to the guy. Spiders are large but up high. They ste not poisonous. I'm actually collecting venomous, brown spiders in my backyard here in California and shipping it for research. So, my point is there are more venomous spiders and snakes in California than in Seychelles. Have fun! Go visit. I wish I could go more often.

Joanna Chandler from On Planet Earth on May 28, 2012:

This was a pretty interesting hub i am afraid of the ocean and seldom goes in, now u made me feel like ever going in again. LOL . also i watched something on sharks recently attacking humans in shallow waters so am good i'd just admire the ocean from far :)

Ktopa on April 23, 2012:

stop scare mongering! ITs more dangerous to go to the UK, USA, China, Russia and Europe... Its the Humans you have to be aware of!

George Toplis on February 26, 2012:

I came across one of those black and white banded sea snakes only three mtrs from shore, I just stood still and it swam close to me then unbelievably swam into the sandy bottom ,I could not believe my eyes how easily it disapeared.

Sara Brankaer on February 20, 2012:

I lived in the Seys for years, went hiking, sailing and snorkeling hundreds of times and never came into contact with any of these terrifying creatures. I never once saw a snake. I saw hundreds of harmless spiders, they rarely come indoors, though, they mostly just hang about in their webs. I did see people get stung by walking into sea urchins (painful,but not deadly), or get stung by jelly fish, again: painful,not deadly. I saw many sharks, mostly when sailing farther out of the coast, sometimes when swimming, but never heard of anyone being attacked by one. I know of centipede stings which can be painful, but it never stopped us walking everywhere barefoot. Just in the see you look before putting your feet down (to avoid sea urchins or lion fish). Don't panic, relax and enjoy the beauty of these islands!

Don't think I'd want to go to the Seychelles with all those poisonous creatures there! Really interesting hub! Voted up and awesome!
