Anomuran and brachyuran crab symbionts of Singapore hard corals of the families Acroporidae, Agariciidae and Pocilloporidae
Anomuran and brachyuran crab symbionts from 51 colonies of corals belonging to the families Acroporidae, Agariciidae and Pocilloporidae were investigated. A total of seven species of anomurans and 27 species of brachyurans were collected, of which the majority were corallophilous symbionts. Comparisons with studies made at four oceanic reefs revealed a paucity of brachyuran corallicolous symbionts, with only four species of Anomura and four species of Brachyura observed in Singapore. However, there was a high abundance of corallophilous and casual symbionts in Singapore.
