Pocillopora damicornis（Linnaeus）在大堡礁蜥蜴岛具有季节性配子发生和浮游藻释放，这与之前关于其他地点该物种的一些报道形成鲜明对比。在同一时间取样的菌落中，释放的浮浪虫数量和性腺发育差异很大，但繁殖活动主要发生在冬季。 damicornisplanulae 优先定居在藻类覆盖的基质上，而不是裸露的珊瑚基质上，但随后的死亡率与这种定居偏好成反比。与藻类的竞争和生物干扰导致卵在沉降和生长的不同阶段死亡。
Pocillopora damicornis(Linnaeus) has seasonal gametogenesis and planula release at Lizard Island, Great Barrier Reef, in contrast with several previous reports on the species at other locations. The number of planulae released and gonad development varied considerably among colonies sampled at the same time, but reproductive activity occurred predominantly in winter.P. damicornisplanulae settled preferentially on algal-covered substrata, rather than bare coral substrata, but showed subsequent mortality inversely related to this settlement preference. Competition with algae and biological disturbance contribute to spat mortality at different stages of settlement and growth.
