Outline of Final Research Achievements	The timing and mode of sexual reproduction were investigate in two species of Pavona and Psammocora contigua in Okinawa, Japan. P. contigua was observed to shed gametes following the full moon in July to September. Spawning of Pavona divaricata was observed for following full moon in July to October. Spawning of Pavona decussata was also observed for following full moon in the November and December. The genetic variation of population of the P. divaricata, P. decussata and P. contigua were examined in ten sites at Ryukyu Archipelago, using DNA sequence of ribosomal DNA Internal Transcribed Spacer (ITS) region. The level of differentiation among populations were variants. During an ecological study of scleractinian corals, we found the new species of Zanclea hydroids associated with several scleractinian corals.
