Phylum bryozoa.

Bryozoans, traditional phylum name Bryozoa, new phylum name Ectoprocta, are often commonly known as moss animals. They are sessile, colonial animals that can form erect sturdy colonies or can encrust rocks and other organisms' carapaces forming a uniform 'moss-like' covering. The colonies are composed of individual zooids.Phylum: Bryozoa Ehrenberg, 1831 ... Bryozoa: {gr, bryon}, musgo. ...
