Phylum Bryozoa – Bryozoa are tiny filter-feeding colonial organisms which build a calcium carbonate structure which have varied appearances (lacy fans, corkscrews, and twig-like shapes are common). Phylum Brachiopoda – Brachiopods are shelled organisms which have a left-right symmetry across their valves (shells).The phylum Bryozoa (Ectoprocta) is comprised of approximately 6,000 living species of sessile, colonial, aquatic organisms and has an extensive fossil record that dates back to the Early Ordovician. There are two known classes of bryozoans, Gymnolaemata and Phylactolaemata.

By 1891 bryozoans (ectoprocts) were grouped with phoronids in a super-phylum called "Tentaculata". In the 1970s comparisons between phoronid larvae and the cyphonautes larva of some gymnolaete bryozoans produced suggestions that the bryozoans, most of which are colonial, evolved from a semi-colonial species of phoronid.

Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.

Bryozoans (commonly called moss animals) are generally sessile, colonial invertebrates that belong to the phylum Bryozoa (or Ectoprocta), which is sometimes combined with two other phyla (Phoronida and Brachiopoda) to form a possible clade within the Deuterostomia. The three are sometimes referred to as the Lophophorata.Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves.
