Squid Worms (Teuthidodrilus samae) are interesting because they are remarkably abundant, and are relatively large for a deep sea creature. They measure about four inches in length. The name comes from the ten tentacles that protrude outward from the head. The Squid Worm also has iridescent bristles that run down the length of their body, aiding in movement. They feed off of plankton and small floating debris.
Another notable fact about the Squid Worm is that it might be a transitional species; and animal that stradles the line between species that reside on the sea floor, and those that swim openly. Such transitional species are important in understanding evolutionary history.
