Platypus venom causes excruciating pain that can last for months on end, which cannot be relieved with conventional painkillers. Not even morphine works against it. The venom causes victims to become nauseated, suffer from cold sweats, and can even cause muscles to waste away.
The individual animal with the most human kills ever was a tiger from Northern India, which adjusted its hunting strategy to kill people after a tooth injury left it unable to hunt normal prey and was shot after an estimated 436 kills.
The original word for ‘bear’ has been lost. People in middle ages were superstitious and thought saying the animal’s name would summon it. They called it ‘bruin,’ which means ‘the brown one’ to avoid saying its actual name, and then bruin segued into bear.
