The Platypus
Male platypuses will fight for their love during mating season using their ankle spurs to inject their targets with a powerful toxin. Platypuses can also use their venom on other animals that attempt to attack them like tigers, lions, bears, and dingoes. Fortunately, if a human gets jabbed by one of these animals, they won’t die from the venom. But they may experience side effects like edema and a nasty headache.
