Bryozoa is a phylum of small aquatic invertebrates that filter feed with tentacles lined with cilia. Most species are marine and live in tropical seas, although many are in temperate or cold seas, and some live in brackish or freshwater. Of the ~ 4000 extant species, all but one genus is colonial.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 are most commonly suspension feeders, although some species may use their tentacles to move food particles to their mouths. In some species, the ciliated tentacles of the lophophore are arranged in a horseshoe shape, while in others they are arranged circularly. In species with the first pattern, there is a food groove at the base of ...All bryozoans are colonial except one genus, Monobryozon.
