Fig. 3From: The life of the freshwater bryozoan Stephanella hina (Bryozoa, Phylactolaemata)—a crucial key to elucidating bryozoan evolutionGeneral morphology of colonies of Stephanella hina. a Lateral view of a colony, showing several individual zooids extending their lophophores into the water column. Note that the polypides extend vertically from the substrate. The transparent ectocyst can only be discerned by particles adhering to it. b Top view of a colony showing the arrangement of the individual zooids within the colony and the typical horseshoe-shaped lophophore.
