Bryozoan is the name of a colonial sessile animal encased in a protective covering with an opening for its tentacles that are lined with cilia for feeding. Bryozoans feed by sieving particles of food out of the water and live in colonies. The phylum Bryozoa is made up of over 4, 000 species and only one genus is solitary while the rest are colonial.
