Ctenostomata

The Ctenostomata are an order of bryozoans in the class Gymnolaemata. The great majority of ctenostome species are marine, although Paludicella inhabits freshwater. They are distinguished from their close relatives, the cheilostomes, by their lack of a calcified exoskeleton. Instead, the exoskeleton is chitinous, gelatinous, or composed only of a soft membrane, and always lacks an operculum. Colonies of ctenostomes are often composed of elongated, branch-like stolons, although more compact forms also exist.

CupuladriaW
Cupuladria

Cupuladria is a genus of bryozoans in the suborder Flustrina.

CyphonautesW
Cyphonautes

A cyphonautes is a larva of an ectoproct or bryozoan. It is triangular in profile with a heavily-ciliated band called the corona at the base of the triangle and a sense organ at the apex. The beating of coronal cilia propels the cyphonautes through the water and contributes to a feeding current. The cyphonautes is very thin, i.e. laterally compressed, and is bounded laterally by two valves or shell plates. The internal anatomy of the archetypical cyphonautes, such as the one featured in the life cycles of Membranipora, includes a complete digestive tract with a stomach entrance near the apex and a hindgut ending in an anus near one end of the base. At the other end of the triangle's base is the pyriform organ, a heavily ciliated and glandular complex that functions in site selection at settlement.

CystoporidaW
Cystoporida

Cystoporida is an extinct order of bryozoans in the class Stenolaemata.

FenestellidaeW
Fenestellidae

Fenestellidae is a family of Bryozoans belonging to the order Fenestrida. The skeleton of its colonies consists of stiff branches that are interconnected by narrower crossbars. The individuals of the colony inhabit one side of the branches in two parallel rows or two at the branch base and three or more rows further up. Zooids can be recognized as small rimmed pores, and in well-preserved specimens the apertures are closed by centrally perforated lids. The front of the branches carries small nodes in a row or zigzag line between the apertures. Branches split from time to time giving the colonies a fan-shape or, in the genus Archimedes, create an mesh in the shape of an Archimedes screw.
