Little attention has been paid to the\\nsexual reproduction of Millepora compared to scleractinian corals. This\\nstudy is aimed to trace the developmental processes of medusae and\\nampullae throughout one year.\\nRegular sampling of Millepora intricata and Millepora tenella was\\nconducted for histological examination of the oogenesis and\\nspermatogenesis between October 1996 and October 1997 at Sesoko\\nIsland, Okinawa (26\u00b038\u0027N, 127\u00b052\u0027E). Medusae released from M.intricata at Mizugama, on the west coast of Okinawa Island, were also\\nexamined.\\nAmpullae were observed in M.intricata from May to July in 1997, M.tenella ampullae were observed only in May of the same year. In both\\nM.intricata and M.tenella, it took approximately 25 days from the\\nearliest developmental stage to mature medusa release. M.intricata seemed to release medusae in the last quarter of the lunar cycle. Simple\\nmedusa indicates their incapability to catch prey. Nematocysts on the umbrella may be used for protecting gametes from predators, but are\\nunlikely used to capture prey given such a short life-span.\\nCoincidental developmental stages among the colonies of each species\\nindicates synchronous medusae release. Synchronous release of medusae\\namong colonies appears to be necessary in Millepora because short-lived\\nmale and female medusae are released from separate colonies.", "subitem_description_type":
