Abstract
Dendronephthya gigantea (Verrill, 1864), the dominant species in the waters surrounding Jeju Island, Korea, is a gonochoric internal brooder that releases its planulae from July to September. The ratio of females to males in this azooxanthellate soft coral is 2:1. Oogenesis takes place for 12 months and spermatogenesis for 3-5 months. Gametes mature as seawater temperatures increase, suggesting a seasonal factor in the reproductive cycle. Planulae brooded in the gastrodermal canal were expelled around the times of the full moon and the new moon; a significant difference in numbers expelled was not found between day and night. Ciliated planulae had negative buoyancy after planulation, and showed rapid metamorphosis into a primary polyp stage within 2 days. © 2007 Springer-Verlag.
