Phylum Entoprocta (banded moss animals)
The Phylum Entoprocta superficially resemble bryozoans (as well as some cnidarians and protozoans like Vorticella) in that they are minute, sessile tentacle-feeders. Only a single genus is known from North America.
The name “Entoprocta” refers to the position of the anus adjacent to the mouth within the ring of feeding tentacles. This is in contrast to the bryozoans, which also have a U-shaped gut, but the anus is located outside the lophophore. Hence the alternative name for bryozoans, “ectoprocts.” Entoprocts are otherwise built like little protostome invertebrates.
