香港的珊瑚群落支持两种以活珊瑚组织为食的腹足类动物：Drupella rugosa和Cronia Marariticola。它们剥离了珊瑚骨骼上的组织，留下了一道白色的摄食疤痕，很快就会随着定居的藻类褪色。它们从活组织/死亡组织界面的边缘取食，并经常在这个界面上发现成团。优先捕食分枝珊瑚Acropora spp.和泡孔虫科，它们统治着许多印度-太平洋珊瑚礁(例如，Turner 1992,1994；Cumming 1996，审查中)。但这些珊瑚在香港分别是稀有的和没有的，而且大多数珊瑚群落以大型和结壳物种为主(Veron 1982记录了49种珊瑚物种)。在这里，皱纹盘藻捕食通常会被避免的物种，比如中华扁豆。我们观察到下列属的群体被放牧
Hong Kong’s coral communities support two muricid gastropod species which feed on live coral tissue: Drupella rugosa and Cronia margariticola. They strip the coral skeleton of tissue, leaving a white feeding scar which quickly discolours with settling algae. They feed from the edge of the live/dead tissue interface and are often found clumped at this interface.Drupella spp. prey preferentially on the branching corals Acropora spp. and Pocilloporidae, which dominate many Indo-Pacific reefs (eg Turner 1992, 1994; Cumming 1996, under review). But these corals are rare and absent, respectively, in Hong Kong, and most coral communities are dominated by massive and encrusting species (49 coral species were recorded by Veron 1982). Here, Drupella rugosa preys on species that would usually be avoided, like Platygyra sinensis. We have observed colonies of the following genera being grazed
