Sea wasp or box jellyfish
The most dangerous animal in the marine world is, without a doubt, the sea wasp or box jellyfish, scientifically called, Chironex fleckeri. It is a jellyfish and although many people believe that they simply produce hives and burns that can be more or less painful, the truth is that this particular species is poisonous. It is one of the most poisonous animals in the world, since its venom is lethal with little quantity, and more specifically, it is the most poisonous animal in the world.
It lives in Australian waters and many people have died over time from its sting, because by injecting a little less than 1 and a half milligram of its venom, this jellyfish is capable of killing an adult human in a short time, without even give yourself time to swim back to shore. Like many poisons in the animal kingdom, it attacks the nervous system, producing paralysis, immense pain and, finally, causing a collapse of the nervous and cardiovascular systems. stopping the heart.
This terrifying animal due to the effect of its contact, is one of the largest jellyfish, since its head can measure about 25 cm but also counting its tentacles it can measure 3 meters and weigh a couple of kg.

They attack us because they feel threatened by our presence or out of pure curiosity, to know what we are, many of their attacks are not deadly although they can be.
Sea snake
The cobras or sea snakes, scientifically known as Hydrophiinae are poisonous snakes and, in fact, their venom is more powerful than that of ground cobras. There are several species of these such as yellow or striped, but all have flat or rowing tails, an adaptation to aquatic life.
These sea snakes live in the Pacific Ocean and the Indian Ocean. Their basic food is fish, crustaceans and mollusks, so we are not in danger of being their prey, but we are in danger of being attacked if they feel cornered, invaded or scared, because they attack us only to defend themselves.
