Platypus
The platypus might not look like a dangerous create that can inflict pain but it hides a secret. The strange looking creature is one of the only mammals that produce venom, which it is able to use thanks to spurs on its ankles. While it isn’t fatal to humans it is known to be excruciatingly painful, so much so that it can even cause the victim to faint. Scarily, the pain has been known to last for months, though it will usually subside in just a few days.
