Pufferfish
Tetrodotoxin, a chemical 1,200 times more toxic than cyanide, is present in almost all pufferfish. And don't let their tiny size deceive you.
Hippopotamuses
Hippos kill more people than any other creature in Africa because of their extreme aggression and territoriality, along with their utter unpredictability.
Platypuses
A platypus utilises the venom in the spur of its rear foot to attack and kill its prey. It is one of the few poisonous animals on Earth.
Rhinoceroses
Their bad eyesight and senses for their surroundings make them even more unpredictable.
Box Jellyfish
Box jellyfish attacks are known as "the most explosive envenomation process that is presently known to humans".
Poison Dart Frogs
As beautiful as they are poison dart frogs are very poisonous. They use their colors to ward off potential predators.
African Lions
Found in sub-Saharan Africa, these lions usually do not target humans, but they have killed dozens.
Boomslang Snakes
Boomslangs don't appear to be particularly dangerous. However, if one did attack you, even modest amounts of its poison would gradually kill you by causing haemorrhages.
