Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.

Lophotrochozoa is a protostome clade that includes disparate animals such as molluscs, annelids, bryozoans, and flatworms, giving it the distinction of including the most body plans of any of the three major clades of Bilateria.

Bryozoans . They are aquatic invertebrates that live in sedentary colonies. Bryozoans live in tropical waters, polar waters and oceanic trenches. They have a crown of tentacles called lophophores that are used as feeding structures. They are classified into – Stenolaemata – Marine bryozoans; Phylactolaemata – Freshwater bryozoans

Identification: Plumatella repens is a species of freshwater bryozoan in the class Phylactolaemata. Like other species of bryozoans (also known as Ectoprocta or commonly as moss animals), the individual microscopic aquatic invertebrates (called a zooid) live directly on submerged surfaces in a colony (Ricciardi and Reiswig 1994, Wood 2010, Rubini et al. 2011).Bryozoans. Introduction. The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals.
