10 Most Poisonous Animals in the World

Box Jellyfish

Box jellyfish are considered among the deadliest creatures in the sea. Their venom can cause severe pain, heart failure, and death within minutes. 

Gila Monster

The Gila monster, native to the USA and Mexico, is known for its excruciating bite. Although its venom is a mild neurotoxin

Sydney Funnel-Web Spider

The Sydney funnel-web spider’s venom is extremely toxic to humans but harmless to many other animals. The venom’s molecules could potentially be used to treat heart attacks

Cone Snail

Cone snails use venom to hunt fish with a venom-filled harpoon. Their sting can cause respiratory failure, muscle paralysis, and death.


Stonefish, with their excellent camouflage, can easily be stepped on, causing an incredibly painful sting from their dorsal spines. 

Inland Taipan

The inland taipan, the most venomous snake, has a venom so potent it can kill within an hour. Native to Australia, it is extremely shy and rarely encounters humans.


The platypus, an egg-laying mammal, has venomous ankle spurs that deliver a painful sting. While not fatal to humans, the venom can paralyze and kill smaller animals.

Slow Loris

The slow loris, the only venomous primate, secretes a toxin from its brachial gland and activates it by mixing it with saliva. 


Shrews, particularly the northern short-tailed shrew, have venomous bites that paralyze their prey. The venom flows from ducts at the base of their incisors. 

European Mole

The European mole uses toxic saliva to paralyze earthworms, storing them alive for later consumption.
