Bobbit worms are predatory animals feeding on fish, crabs and other underwater species. They bury themselves in the ocean floor, only exposing their five antennae which can sense movement. Once they sense their prey, the worm attacks it with their razor sharp teeth and pulls it underground. One should never touch a Bobbit worm as their body is composed of numerous bristles which are in fact nerve-damaging. The bristles can deliver a painful sting. If one of these bristles pierces through the skin, one might suffer from permanent nerve damage.
