collection. These data were counted by using quadratic transect with 4 x 4 m2 in
size. The results showed that P. demicornis are clustered about 52 m from the
shoreline reaching 0.5 m depth at the station I. Similar feature of distribution was
also seen at the station III, however, none was found at the station II. Coral
coloniesof P.damicornisfound on the station I amounted to 59 colonies with an
