This contribution is the second of a series of detailed morphological analyses of this understudied clade of bryozoans. The morphological investigation of Haywardozoon pacificum revealed numerous characters that show a closer relationship to Flustrellididrae rather than Hislopiidae ... •Bryozoans are colonial and display characteristic zoarium (colony) and zooid morphology/anatomy. •Bryozoans can't eliminate nitrogenous waste, instead storing it in their tissues. They then can "eliminate" their internal tissue and regenerate from their body walls. We studied by SEM the external morphology of the ooecium in eight bryozoans of the genus Cauloramphus (Cheilostomata, Calloporidae): C. spinifer, C. variegatus, C. magnus, C. multiavicularia, C. tortilis, C. cryptoarmatus, C. niger, and C. multispinosus, and by sectioning and light microscopy the an …
