So here's a little cone snail that hunts fish and here is a much bigger cone snail that also hunts fish. And indeed, size matters, because if this little cone snail stings you, you might feel pain and a little numbness, but it can't kill you. But this snail, which is large, has enough venom so if it should sting you, your life is in danger. And in fact, in the absence of medical intervention, when people get stung by this particular species, the geography cone, or conus geographus, 70% of the people die.
