Christmas tree worm

The Christmas tree worm (Spirobranchus giganteus) is a small, tube-building marine polychaete worm. Both its common and Latin names refer to the two spiral structures, the most common feature seen by divers, which resemble Christmas trees. These are specialized mouth appendages which trap prey microorganisms and also act as respiratory structures.
