Phoronida

Phoronida, horseshoe worms, is a phylum of worm-like filter-feeders that use ciliated tentacles called a lophophore. Species with the lophophore folded into a U-shape inspire the common name of horseshoe worms. There are only a dozen or so species. Length varies from a quarter inch to about a foot. Most build a tube. Distribution is temperate or tropical oceans with a depth of less than 180 feet. For more information, visit the Wikipedia entry Go back to Brachiozoa
