Evolution really went overboard with the cone snail! This beautiful little assassin packs tetrodotoxin that's 1000x more potent than cyanide. Classic evolutionary arms race - tiny creature gets deadly superpower while looking like a fancy piece of jewelry. Nature's ultimate "don't touch me" message wrapped in a deceptively gorgeous package. Small but deadly is nature's favorite punchline.
Fun fact: Some cone snail toxins are so specialized they're being studied for potential painkillers more powerful than morphine. From "I'll kill an elephant" to "I'll help your backache" - talk about range!
