What does the platypus's stinger do?

Answer 1

The platypus does not have a stinger, but the male has a poisonous spur on its ankle. Used as defence, the spur can deliver enough venom to kill a small dog, or cause extreme agony for a person.

Answer 2

Oh, dude, the platypus's stinger is actually not a stinger at all. It's more like a spur located on the hind legs of males that can deliver venom. So, it's not really for stinging like a bee or a scorpion, but more for defending territory and competing with other males. It's like nature's way of saying, "Back off, bro."
