Leopard
With most animals, when they’re wounded then they run and hide. Leopards are the exception to this rule. When they’re hurt, they become even more dangerous. To top it off, leopards are incredibly strong. They usually hide their prey out of reach, meaning they drag dead antelopes up trees.
Eastern Brown Snake
You may not guess it from the name, but the Eastern Brown Snake is responsible for roughly half of the deaths from snake bites in Australia each year. When this snake bites someone, that person is normally dead within four hours or so.
