10. Poison Dart Frogs
While only 1 to 6 centimetres in size, these little guys secrete enough neurotoxin from their backs to kill 10 human beings.
9. Cape Buffalo
Also known as African buffalos, they can weigh up to 1,000 kilograms and have huge, curved horns that can gore and kill anything that gets in their way. Stampedes are another threat.
8. Polar Bear
They are the largest land carnivores and can be found near the Arctic. Powerful enough to kill beluga whales, polar bears have been also been classified as a threatened species due to environmental factors and human causes
7. Elephant
They may look like gentle giants, but there is no mistaking the deadly potential of their crushing weight (on average, 7,257 kilograms for African elephants) and those sharp tusks that can grow up to 3 metres long!
6. Australian Saltwater Crocodile
The world’s largest reptile can patiently wait in the water and then quickly emerge to grab, twist, roll and tear at their prey.
5. African Lion
These majestic animals’ razor sharp claws, fangs, strength and agility make them incredibly dangerous hunters.
4. Great White Shark
This predator of the sea can grow up to around 6 metres long and has 3,000 teeth at its disposal. Though they’re not as dangerous as JAWS would have you think, they still have been known to attack humans.
3. Australian Box Jellyfish
Pale blue and transparent, these jellyfish have enough toxin in their 4.5 metre long tentacles to kill 60 people.
2. Asian Cobra
Even though it’s not the longest venomous snake in the world, the Asian cobra is still one of the most feared: it is responsible for a majority of the deaths related to snake bites.
1. Mosquito
These tiny insects are often a nuisance, but they are also the deadliest: they can transmit fatal viruses and diseases like malaria, which claims more than two million lives each year.
