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. General Features of Brachiopod Shells: Brachiopod shells have two valves that are distinct in shape and size. The brachial valve is usually the smaller of the two valves and has supports on the inside to help support the lophophore. The pedicle valve is usually larger than the branchial valve and has a hole through which the pedicle passes (the …Introduction.

Bryozoans are filter feeders, which means they extract food particles from the water. They play an important role in cleaning the water and helping to prevent eutrophication (when excess nutrients in the water lead to harmful algal blooms).

One of the big mysteries of early life has been solved as fossil evidence proves an ancient group of organisms to be much older than previously known. The oldest fossils of bryozoans, colonies made of tiny individual animals called zooids, were ...Bryozoan. Bryozoans (from the ancient Greek for “moss animals”) are so named because some living bryozoan colonies resemble mosses. Not to be confused with plants, bryozoans are invertebrate animals with a long fossil record, from the Early Ordovician Period to the present. Modern species inhabit freshwater, brackish, and marine environments. 16 мая 2008 г. ... Freshwater bryozoans are fairly common and are found in warm water lakes, streams, and rivers usually attached to submerged sticks.And while zooids are small individuals on their own, colonies can be quite complex. Zooids within a single colony can come in different functions and morphologies – a bit like the organs in our bodies.
