Bryozoans, also known as the Polyzoa, Ectoprocta or moss animals, are a phylum of small aquatic animals living in colonies. The colonies usually have a skeleton of calcium carbonate.

You may have thought they were fish eggs, some kind of water mushroom, a ...Zooids have a u-shaped crown of 19-24 ciliated, orange translucent tentacles, called a lophohpore, which is extended through its aperture to feed. W. Subtorquata lacks spines, avicularia, and ovicells common to many bryozoans. An identifiable characteristic is its black, sinusoid aperture, having a convex proximal border (Cohen 2005).

Bryozoan biology. Each individual animal, or zooid, has a simple body style, usually round or oval in shape with a single opening that serves as both a mouth and an anus.
