Overview

Comprehensive Description

General Description

Bryozoans in this family form erect or encrusting colonies. Frontal wall well developed umbonuloid. Primary orifice without a sinus, uncalcified; obscured by calcified peristome and secondary orifice. Marginal areola present. Frontal spiramina evanescent or permanent, single or multiple. Avicularia usually present.

General Description

Colony encrusting or erect, arising from an encrusting base and anchored by partially calcified, kenozooidal rhizoid system. Erect forms highly calcified, branching, bilaminar, sometimes fenestrate, often massive and very large. Zooids with umbonuloid frontal shield, with marginal areolae and central spiramen complex. Secondary orifice subterminal, with adventitious, oral avicularia; other interzooidal and vicarious avicularia typically present. Brooding in interior ovisacs of enlarged zooids with dimorphic orifices. (after Harmer, 1957, Bock & Cook MS).

Wikipedia

Adeonidae

The Adeonidae is a family within the bryozoan order Cheilostomata. Colonies are often upright bilaminar branches or sheets, perforated by large holes in some species (e.g. Adeona cellulosa). The zooids generally have one or more adventitious avicularia on their frontal wall. Instead of ovicells the adeonids often possess enlarged polymorphs which brood the larvae internally.
