Bryozoans<br />
range from<br />
the intertidal<br />
to the deep<br />
sea and can<br />
form<br />
significant<br />
components<br />
of rock-wall<br />
assemblages.
Mostly bryozoan hash

Some bryozoans are habitat-formers —<br />
like species of Celleporaria ...
But what about<br />
Taiwan?

Cryptofaunal bryozoans in coral<br />
environments<br />
Within reefs:<br />
hidden encrusters<br />
cavity dwellers<br />
cavity fillers<br />
dead-coral veneerers<br />
Between reefs:<br />
sediment binders and trappers<br />
sediment stabilisers<br />
Hence, bryozoans can contribute to reef build-up, especially those<br />
species that engage in self-overgrowth or which grow over other<br />
organisms. Such bryozoans tend to become a permanent part of the<br />
calcareous mass that comprises a reef, acting as accessory framebuilders.
