Bryozoans can be found in quiet lakes, ponds, streams and swamps attached to a surface under water. Pros and Cons of Bryozoans

Many bryozoans are polymorphic with zooids specialized for different functions. Gymnolaemata C Gymnolaemate bryozoans are almost entirely marine and have circular lophophores. No epistome and no body wall musculature are present. These are considered to be derived characteristics. Colonies are polymorphic with specialization of zooids. Because these tentacles have several distinctive characteristics that differentiate them from the tentacles of other animals. First, these tentacles are hollow. Hollow cavities in the bodies of animals (except for the gut) are called coeloms : for all brachiopods, phoronids and bryozoans, the hollow cavity in the lophophore is the second of the ...Graphic representation of various types of bryozoans. Source: Ernst Haeckel. Thanks to their appearance, they are normally confused with other organisms that make life in the seas such as algae and corals.

Jan 9, 2001 · Cyclostome Bryozoans. Cyclostomes are an ancient order of stenolaemate bryozoans ranging back to the Lower Ordovician. Although moderately diverse and locally abundant at the present-day, cyclostomes are invariably outnumbered by cheilostome bryozoans and seldom constitute more than 20% of the species recorded in regional bryozoan faunas.

Distinguishing features. Bryozoans, phoronids and brachiopods strain food out of the water by means of a lophophore, a "crown" of hollow tentacles. Bryozoans form colonies consisting of clones called zooids that are typically about 0.5 mm (1 ⁄ 64 in) long.

The phylogenetic position of bryozoans provides a valuable opportunity to investigate the evolution of developmental traits. Even though the kinship of Bryozoa remains inconclusive – the group is more closely related either to Entoprocta and Cycliophora or to Phoronida and Brachiopoda , or both – most phylogenetic analyses place the ...The body of these animals is often smaller than the hydroids that they superficially resemble, but it is far more complicated.
