Different variants of colony-wide water currents were described for bryozoans. Among them, the most specific way of the water removal in encrusting colonies is a formation of excurrent water outlets, or chimneys, which were first described for large colonies of Membranipora membranacea (Linnaeus, 1767) ( Banta, McKinney & Zimmer, 1974 ).Bryozoan colonies vary in size.
