The Box Jellyfish is considered one of the most venomous marine animals in the world. Their tentacles are covered in millions of microscopic nematocysts that inject a powerful venom, causing intense pain, scarring, and in some cases, death.

While not as deadly as some other animals on this list, the Honey Bee is responsible for more deaths in Australia than snakes, spiders, or sharks. This is due to the high number of people who are allergic to their venom, which can cause anaphylactic shock.

3. Saltwater Crocodile
