Top 10 Most Poisonous Animals in the World

Asian Tiger Snake

#10

Commonly known as a tiger keelback. This Asian and southeast Asian tiger snake sequesters its toxin from number seven on this list of the top 10 most poisonous animals in the world: the cane toad.

Hooded Pitohui

The hooded Pitohui of the Pitohui genus found in New Guinea. The bird stores a toxin known as batrachotoxin in its feathers and and skin.

#9

#8

Hawksbill Sea Turtle

The hawksbill sea turtle is poisonous because of what it eats: jelly fish and sponges. This turtle‘s flesh and fat absorb the toxins from the sponges and jelly fish it eats, making them poisonous when ingested but leaving the turtle unharmed.

#7

Cane Toad

The cane toad, also known as a marine toad is found ironically on terrestrial land in South and Central America. Number seven on the top 10 most poisonous animals in the world list stores a type of poison in its glands called bufotoxins, making it particularly poisonous when ingested.

Poison Dart Frog

These aposematic Central and South American amphibians are also known to produce 28 different alkaloid poisons which they accumulate through their diets of ants, termites and centipedes. Poison dart frogs are not safe to handle as they store their poison in their skin.

#6

Spanish Fly

#5

The Spanish fly is not a fly, but rather a beetle found across Europe and Asia. These emerald green beetles are part of the blister beetle family, because the toxin they produce called cantharidin is a blistering causing agent.

#4

Comb Star

Comb stars, are the most widespread type of sea star in the Indo-Pacific region. Like pufferfish and rough-skinned newts, comb stars poison using tetrodotoxin. The echinoderm stores the toxin in its spikes or spines.

Rough-skinned Newt

Newts produce tetrodotoxin that is stored in their skins and when ingested is particularly poisonous. The number three on the top 10 most poisonous animals in the world uses this toxin to defend itself from predators.

#3

Striated Surgeonfish

#2

Number two on the top 10 most poisonous animals in the world list, this fish eats algae which means it occasionally ingests dinoflagellates. Dinoflagellates when concentrated produce a toxin known to cause neurological damage to humans and can be fatal.

Pufferfish

Also known as blowfish, these fish are a delicacy in Japan. However, the liver, kidneys and spikes of pufferfish are incredibly poisonous. The toxin produced by these fish is tetrodotoxin, which is 1,200 times more deadly than cyanide. One pufferfish is enough kill 30 human adults.
