Fouling sponges (porifera) on navigation buoys from Singapore waters.

摘要: A total of 62 sponge species was identified from subtidal (0-2 m depth) marine fouling communities present on 30 navigation buoys in the Singapore and Johor Straits examined between 2003 2006. Of these sponges, eight were new records for Singapore. Systematic descriptions are given six most prevalent species, which occurred at least nine a examined. These are: Suberites diversicolor, Tethya robusta, Mycale (Carmia) sp. "red, encrusting", (Zygomycale) parishi, Amorphinopsis excavans Cladocroce "massively encrusting". The number sponges any single buoy ranged two 23 with four seen majority large proportion (67%) rare, occurring fewer than three during three-year study period. This is possibly due to small surface area buoys. In study, only 19% (12 species) specimens level. further 16% tentatively assigned known but require comparison type material confirmation. remaining 65% genera treated as operational taxonomic units (OTUs). An inventory all associated also provided.
