Sea lions are considered to be cute animal. They can be easily trained and many became the stars in zoo. But the cuteness of this animal fades away in the sea as sea lion attacks often on human beings.

These symptoms can last for weeks. These fish are generally found in Eastern Atlantic and Caribbean Sea.


8) Puffer Fish:

This fat bodied Puffer fish contains a deadly poison or toxin called as Tetrodotoxin (TTX). This toxin is more powerful than cyanide and cause difficulty in breathing before leading to death. A single puffer fish contains enough toxins to easily kill more than 30 human.  In Japan these fish are considered as delicate in spite of the fact that one cut by these can certainly cause death. In Japan this fish is served as a delicious meal after removing the poison. 

7) Stone Fish:

There are two most important reasons behind its danger. First is that it is the world’s top most toxic fish. Second reason is that since its body is in stone shape so it can easily hide among rocks underwater, thus adding to the danger. The size of this fish is small approximately 12 inches. The dorsal area of the fish is creased wish thirteen spines which release toxin that causes severe pain, temporary paralysis, tissue death and can even lead to death if medical attention is not provided. Swelling and excruciating pain remains for months even after treatment. They are generally found above Tropic of Capricorn and in Indo-Pacific Ocean.

6) Chrionex or Box jellyfish:

Box jellyfish is one among the largest jellyfish. They are also referred as ‘sea wasp’ or ‘marine stinger’. They have a bell which can grow as large as a soccer ball.  Each end of the bell contains 15 tentacles. These fish are very popular as they have the ability to kill a person within 4 minutes of attack. It is faster than any type of snake. Sting from box jellyfish can cause intense pain and is often links to brutal effects on heart and nervous system of victim. Applying vinegar can prevent from nematocyst.  Anti-venom for this type of jellyfish does not exist making the above and other natural methods important. They are generally transparent in nature therefore one cannot see them coming. Hence, making it the most dangerous fish. Most of the people die not because of the sting but from the deadly shock caused by the excruciating pain. These are generally found in Northern Australia and a single jellyfish can kill 60 people.. So the divers there should be very careful while diving.

5) Tiger shark:

These are next to great white shark when it comes to fatal attacks. The reason behind this fact is those tiger sharks are generally found closer to shore as compared to white shark. Also these are found in greater number. They are often found in tropical areas.


4) Stingrays:

Severity of the attack of this creature was found on 4 September 2006 when Steve Irwin was attacked by one. Steve Irwin was a biologist and host of Crocodile Hunter. The incident shocked the world and became international headline.

They wait under marshes and other murky surface for the varieties of prey which includes kangaroos, shark, buffalo, monkeys, and even human beings. Since they have great power they twist the prey under water and paralyze it. Primary difference between behaviour of alligators and crocodiles to great white shark is that great white shark generally attacks for feeding purpose but both alligators and crocodile remain aggressive all time and hunt humans at territories. Attack on small boats or canoes are often reported. It is advised to speak to locals of the area about marshes and sea before diving.
