Gymnolaemata is a class of the phylum Bryozoa. Gymnolaemata typically live under seawater and grow on surfaces of rocks, kelps, and even in some cases, on living species like fish. They are mostly marine bryozoans with cylindrical or flattened zooids. The lophophore is protruded by action of muscles pulling on frontal wall. This order includes the majority of living bryozoan species.zh:裸唇纲
