Bryozoans are colonial benthic marine invertebrate calcifiers, important and especially abundant and diverse in southern hemisphere shelf environments. Large heavily calcified colonies can be up to 50 years old, but most longer-lived bryozoans are limited to 10–20 y. Many smaller species are annual. Radial extension in flat encrusting bryozoans is generally on the order of 1–5 mm/y. Erect ...Bryozoans use a food-gathering structure (lophophore) bearing the crown of ciliated tentacles to filter the water and trap algae, small particles of detritus, diatoms and other microscopic organisms. Mouth is situated at the base of tentacles. Food is processed in a stomach, intestine, and passes out of the body through anus.bryozoans have this kind of feeding current, and it apparently was the way that the Paleozoic fenestrates (Figure 6) handled the water from which they fed.
