Top 10 Deadliest Fishes

We sometimes think of fishes as harmless creatures that we either eat or we put on our fishbowls. However, some fishes in the world are very dangerous and can harm human beings. These fishes may look as deadly as their descriptions so if you are interested, read on.

1 – Stone Fish

Number 1 on our list is the Stonefish. From the name itself, it is already evident that it can camouflage itself to look like the other stones in the area. Usually found in the Indo – Pacific ocean or rivers, it can be very dangerous because it is poisonous. Whenever an enemy attacks or whenever it feels threatened, it will automatically release a poison that can either cause paralysis and even death.

2 – Box Jellyfish

Number 2 on our list is the Box Jellyfish. There are times when people see the Box Jellyfish, and they automatically assume that it is harmless. However, it is not harmless at all. Aside from the fact that it can move very fast, being stung by a Box Jellyfish can cause people to get into a shock. It has 15 tentacles that can sting greatly and harm human beings if they are provoked.

3 – Tiger Shark

Puffer Fish

Number 4 on our list is the Puffer Fish.

However, almost all of its organs are highly toxic to human beings. Being injected by the poison of the Puffer Fish can be fatal. It is a wonder why some countries still serve Pufferfish to their customers with the possibility that they can be poisoned as a result. While it is true that the poison is removed by the chef, there might be some traces of the poison in the meat of the Pufferfish. It has caused death among hundreds of people.

5 – Sea Snake

Sea Snake
