SOME NOTES ON NUDIBRANCHS (GASTROPODA OPISTHOBRANCHIA) ASSOCIATED WITH THE FOULING COMMUNITY IN SINGAPORE

Abstract

A survey of nudibranchiate molluscs from local fouling communities is presented here for the first time. A total of 15 species were examined; four are identified to the species level while the rest are undescribed and appear to be new species. All are new records for Singapore. Three, perhaps four families are represented here for the first time. The majority are hydroid feeders, coming from the families Tergiped idae, Facelinidae and Dotidae. This is a reflection of the abundance of hydroid prey species on collecti on substrates. Some observations were also made on hatching period and larval shells of the nudibranchs.
