Gymnolaemata are a class of Bryozoans. Gymnolaemata are sessile, mostly marine organisms and grow on the surfaces of rocks, kelp, and in some cases on animals^{[citation needed]}, like fish. Zooids are cylindrical or flattened. The lophophore is protruded by action of muscles pulling on the frontal wall. This order includes the majority of living bryozoan species.
