Top 10 Most Dangerous Aquatic Species

1 2

Of all the aquatic species that have the power to cause the death of humans, this list compiles the ten most dangerous of them. The modus operandi of all of these animals may be very different – yet each one of them is what we would call ‘dangerous’.


1. Box Jellyfish (Chironex fleckeri)

Although ‘box jellyfish’ denotes the entire Cubozoa class, the most dangerous of them all is the deadly Chironex fleckeri. The venom of this species is the most deadly in the animal kingdom and is reported to be able to kill 60 humans within a period of 3 minutes.


2. Yellow Bellied Sea Snake (Pelamis platurus)

The venom of this dangerous sea snake is several times more potent and deadly than the most venomous land snake. The bite itself is painless and may even go unnoticed by the victim. Symptoms start showing around after half an hour of the bite, and if immediate medical attention is not received, the victim goes into cardiac arrest after six to twelve hours.


3. Saltwater crocodile

Crocodiles are territorial and they do not like intruders. They have been known to attack small boats and canoes and result in human deaths. Though you may argue that this is not exactly an aquatic animal, it hardly matters when you are been attacked by in water.


4. Great White Shark (Carcharodon carcharias)

All of us are familiar with the Great White – the popular star of the movie “Jaws”. Great Whites are expert hunters and know how to immobilize prey and render them helpless while they finish them off. There are reported incidents of Great Whites being responsible for the deaths of innocent swimmers off the coast of USA.


5. Blue-Ringed Octopus

This common name refers to several octopus species of the genus Hapalochlaena – small and beautiful octopuses that have a venom powerful enough to kill humans.
