Bryozoans characteristics

Phylactolaemata. Phylactolaemata [1] is a class of the phylum Bryozoa whose members live only in freshwater environments. Like all bryozoans, they filter feed by means of an extensible "crown" of ciliated tentacles called a lophophore, and like nearly all bryozoans (the only known exception being Monobryozoon ), they live in colonies, each of ...

Stenolaemata are exclusively marine bryozoans, while Gymnolaemate bryozoans are mostly marine, plus a few freshwater types, and Phylactolaemates bryozoans are entirely reshwater. The fossil record of class Stenolaemata extends back as far as 400 million years, into the early Ordovician Era. The Stenolaemata have passed their peak of ...Bryozoa. 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. Bryozoans have a long fossil history, starting in the Ordovician. In their life-style they resemble the polyps which form coral. Bryozoans are also significant biofouling organisms that often interfere with the function of irrigation, water treatment, and industrial cooling systems (Wood, 2005b). The phylum Entoprocta is sometimes grouped with the phylum Ectoprocta (Bryozoa) because of certain similarities; but because these are superficial, this group is discussed in ...Stenolaemata are exclusively marine bryozoans, while Gymnolaemate bryozoans are mostly marine, plus a few freshwater types, and Phylactolaemates bryozoans are entirely reshwater.

A Anatomy and Physiology. 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.Chambers of varying shapes, linear, clavate, flabellate or irregular, ratherroughly, mechanically excavated out of endozonal skeleton in both ramose-twig or frondose-blade growth forms of Paleozoic Bryozoa.

Polymorphism is a common feature and physiological exchange takes place through the pores of the walls among the colony zooids. 10. Bryozoans are hermaphrodites. 11. Gonoducts are lacking in Phylum Ectoprocta. 12. Sperms are released into the coelom and exit through the pores in the lophophore tentacles. 13. Characteristics: Bryozoans, also known as moss animals, are colonial, with the expeption of a single genus. Many colonies form sheets covering rocky bottoms or algae, they are called encrusting bryozoans. Others build bush-like structures resembling small corals. They are hermaphrodites, they change sex during their life span. Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch.
