Platypus venom: Although powerful enough to kill smaller animals, the venom is not lethal to humans. However, it produces excruciating pain which may be intense enough to incapacitate the victim. The pain develops into a long-lasting hyperalgesia that can persist for months+ and does not respond to morphine. And the venom comes from "spurs" on the back feet!
