Graduate University of CAS, Beijing , China Abstract: Sexual reproduction of hermatypic corals is one of the approaches for coral reef restoration. This study is about sexual reproduction actions and larvae development of hermatypic corals, and it is useful for artificial coral ecosystem restoration. Corals in Luhuitou Sanya spawned between the end of March and mid April. Eggs of Montipora turgescens and Acropora robusta were collected when they were spawned in seawater during the night of 11 th April. The development of embryos of both species was recorded. Zygotes had cleavaged to morulas, then developed to prawn-chip shape, and then blastulae. Next, blastulae invaginated, which made blastulae plate-like shape, and then the edge bent to center, which changed blastulae to bowl-like shape. Ciliated gastrulae were formed before they became elliptic or rounded planulae. Planulae developed to coral larvae with tentacles after they settled on substrata. Zygotes of M. turgescens had fulvous zooxanthellae while they were spawned. However, zygotes of A. robusta did not have zooxanthella as they were ejected, so they took free-living zooxanthellae from seawater during the development. Key words: Montipora turgescens; Acropora robusta; coral embryo; coral larval development; zooxanthellae; settlement and metamorphosis Montipora turgescens Acropora robusta ; 收稿日期 : ; 修订日期 : 基金项目 : (KZCX2-YW-227); (2009BAB44B01); ( ); ( ) ( ); ( ) 作者简介 : (1984 ),,,, jieying100@gmail.com
