The bryozoans (Bryozoa, gr. "Moss animals") are mostly marine, colonial and sessile aquatic animals. Most have a calcified skeleton, which can be rigid or flexible depending on the degree of mineralization. The bryozoans filter the water by feeding almost exclusively on unicellular plankton, mainly algae and protozoa.

They form large colonies of microscopic or almost limbs. The name of the group "moss animals" is because many times it looks like an underwater cover of moss. The colony develops from a swimming larva, which is fixed to the substrate by a chitinous disk or stolon from which the first individual develops, which by successive gemations gives rise to the colony or zoarium. The zoo is made up of thousands of individuals or zooids. The zoecio, or protective covering, can be chitinous or calcareous.

The trepostomates have calcareous protective covers and the colonies are laminar, branched or massive.
