Immense physical strength, razor sharp claws and scissor like teeth are not the only weapons animals use. Thousands of animals use highly venomous or toxic poisons to attack prey or defend themselves. Some animals actually shoot poisons towards victims, others store toxins in their glands or skin. Following are the top eight most poisonous animals in the world.


8. Box Jellyfish

Prevalent in the ocean waters throughout Asia and Australia, this dangerous animal goes out of its way to avoid other creatures. Swimmers must definitely avoid the Box jellyfish. The stingers and tentacles on this animal are extremely powerful. Along with causing excruciating pain for weeks, the animal’s venom is capable of stopping the heart or paralyzing the lungs. To top it off, the venom will slowly eat away at the skin.

7. Marbled Cone Snail
Though very slow moving, this snail thrives in reefs throughout the world. The animal uses its strong, toxic venom to catch its prey. While within its shell, the snail shoots out a nose type advice called a proboscis. From the probiscis, a tooth like appendage attaches onto the victim. The venom within the animal is transmitted through the tooth into the victim. This leads to paralysis almost immediately. Humans that have experienced a bite are succumbed by weakness, numbness, nausea and death, when the lungs ultimately stop working.

6. Blue Ringed Octopus

The painless bite from a Blue Ringed Octopus may seem innocuous, however the deadly neurotoxins in the animals saliva immediately begin working. Within a few minutes, a human will experience muscular weakness, numbness, followed by a cessation and breathing and ultimately death.

5. Death Stalker Scorpion

Prevalent throughout North Africa and the Middle East, this arachnid lives up to its name. The stinger on this animal is not overly large or strong, however the sting administered is the most toxic from scorpions anywhere in the world. It causes an intense and unbearable pain, then fever, followed by coma, convulsions, paralysis and death.

4. Stonefish
Inhabiting the waters of the Pacific throughout the Australia coast, this complacent fish resembles a sea rock or coral. With its nearly invisible camouflaged assistance, it attacks many fish that swim nearby. A powerful toxin stored within its 13 spines can stop nearly every animal that it connects with. If contact comes with humans, the venom will cause intense pain, swelling of tissue, shock followed by death.

3. Sydney Funnel Web Spider
One of the most venomous creatures in the Australia outback, the Sydney Funnel Web Spider packs a powerful punch. This spider is large and very aggressive, consistently creating the most powerful venom of any spider. Protecting its burrow, the spider places a web across its entrance that passers by should not enter. From its fangs, the spider delivers a powerful neurotoxin that cause extreme pain and are capable of killing a person within 15 minutes. It’s venom does not affect most mammals but has a very powerful effect on humans.

2. Inland Taipan
This Australian snake is frequently considered the most poisonous snake on earth. One bite from this serpent contains enough potent toxin about 110 milligrams to kill about 100 people. It toxin can cause vomiting and will cease a persons breathing. Fortunately, the Taipan is a very gentle and shy reptile.

1. Poison Dart Frog
While running through the rain forests of Central or South America, do not pick up the Poison dart frog. The frog’s skin contains a toxic chemcal that sickens or kills any animal that touches or eats it. Two micrograms of this deadly toxin (enough to fit on the head of a pin) will easily kill a human being or other large mammanl.
