Abstract

A photographic technique was used to examine morphological differences in the living polyps of Favia speciosa sampled from three sites around Singapore. Eight characters were measured, seven of which differed significantly between the three study sites. Sedimentation rates and character size were much higher at the site closest to the mainland than at the two sites further from shore. Land reclamation and dredging contribute to high sediment rates in Singapore waters; these rates decrease with increasing distance from shore. Large polyps close to the main island of Singapore are possibly a plastic, or selected for, response to high levels of sediment.
