It may be small and slow, but the geographic cone snail packs a wallop. The creature eats fish after paralyzing them with a toxin, researchers find. When its prey swims by, it sends out a poisonous cloud that's packed with enough insulin to make the fish's blood sugar drop, National Geographic reports.
That leaves the prey pretty out of it: "It looks like the fish is completely narced," says an expert. But the snail isn't done yet. Next, it pulls the fish toward it with a so-called "false mouth" that looks like a cape.
