Research and Status of Taiwan Biodiversity Taichung 15-16 August 2008

Bryozoans range from the intertidal to the deep sea and can form significant components of rock-wall assemblages.

Mostly bryozoan hash Washed bryomol gravel Some bryozoans are habitat-formers —

like species of Celleporaria ... But what about Taiwan? Liu, Yin & Ma “Biology of Marine- Fouling Bryozoans in the Coastal Waters of China” Beijing 2001

Lists all fouling coastal bryozoans of western Taiwan Strait

Hard and soft shores along the Strait of Taiwan on the west coast Hard and soft shores along the Pacific east coast Celleporaria pilaefera Hippoporina indica Schizoporella errata Keelung

Cryptofaunal bryozoans in coral environments

Within reefs: hidden encrusters cavity dwellers cavity fillers dead-coral veneerers Between reefs: sediment binders and trappers sediment stabilisers

Hence, bryozoans can contribute to reef build-up, especially those species that engage in self-overgrowth or which grow over other organisms. Such bryozoans tend to become a permanent part of the calcareous mass that comprises a reef, acting as accessory frame- builders.
