Eunice aphroditois

''Eunice aphroditois'' is a benthic bristle worm of warm marine waters. It lives mainly in the Atlantic Ocean, but can also be found in the Indo-Pacific. It ranges in length from less than to nearly . Its exoskeleton displays a wide range of colors, from black to purple and more. This species is an ambush predator; it hunts by burrowing its whole body in soft sediment on the ocean floor and waiting until its antennae detect prey. It then strikes with its sharp mandibles. It may also be found among coral reefs.

The species is called the sand striker or trap-jaw worm. Traces of their burrows have been found among fossils near Taiwan dating back 20 million years. A highly popularized name is bobbit worm or bobbitt worm, which is believed to derive from the John and Lorena Bobbitt case. Provided by Wikipedia
