Image of Limy tube worm

Description:

This tiny individual, with a tube less than 1/2 cm long, is attached to a bryozoan. Note the coiling of the tube in tiny individuals such as this. The funnel-shaped operculum is visible to the left of the radioles. The gray, forklike object projecting down to the left from one of the coils is a tiny phoronid worm about 2 mm long. Cilia on the worm's forked lophophore are beating strongly.
