A bryozoan colony is composed of identical linked animal units (zooids). An individual zooid consists of a partially protrusible organ system (= polypide) surrounded by a body wall. The polypide bears a large retractable lophophore with cilated tentacles used to collect food.Business, Economics, and Finance.

CryptoBryozoans feed on small particulate material and would probably do well in some aquaria, particularly those with a good sand bed which produces a lot of bacterial particulates. They may also feed on the smaller varieties of phytoplankton such as small Nannochloropsis species.Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Bugula neritina forms flexible bushy colonies, branching biserial, to about 10 cm high and is purplish-brown in colour.
