Pufferfish
Don’t let this ridiculous looking animal that gained some fame in Finding Nemo fool you, the Pufferfish is one of the most poisonous animals in the ocean – to the point where fishermen refuse to touch them without thick gloves.
2.
Poison Dart Frog
Okay, so the danger for this little guy is right there in his name, but in fairness if you stumble across this dude out in the wild you’re unlikely to exchange pleasantries than to suffer its poisonous wrath. Native Americans used its venom on the tips of blowdarts, that’s how dangerous its poison is.
3.
Blue-Ringed Octopus
An octopus by nature is generally kind of freaky, but the tiny blue-ringed variety is pound-for-pound one of the most venomous animals in the world, and lucky us, there exists no antivenom for its deadly poison.
4.
Slow Loris
Looking like that, and having the word “slow” in its name probably makes you think the Slow Loris is perfectly harmless, but the fact is this little guy is one of the very few poisonous mammals in the world, and a simple lick could infect you with its deadly toxin.
5.
Black Widow Spider
It’s not much of a secret that the black widow spider is extremely dangerous, as they are considered the most venomous species of spider in North America, though fortunately fatalities are pretty rare following a black widow bite.
6.
Anopheles Mosquito
Mosquitos are always annoying, but the Anopheles mosquito in particular is horrifying as its bite has a nasty tendency to infect victims with malaria.
7.
Tsetse Fly
Found throughout Africa, the Tsetse fly is a mass murderer of both humans and livestock, with its bite potentially infecting the victim with a parasitic disease that has killed thousands.
