珊瑚礁是浅水海洋生态系统中最具生物多样性的，但由于人类活动和气候变暖，世界范围内的珊瑚礁正在退化。对3235种珊瑚鱼、珊瑚、蜗牛和龙虾的地理范围分析表明，每个分类单元中有7.2%至53.6%的物种具有高度限制的范围，使它们容易灭绝。范围有限的物种聚集在特有的中心，就像陆地分类群所描述的那样。10个最丰富的特有种中心覆盖了世界上15.8%的珊瑚礁（0.012%的海洋），但包括44.8%至54.2%的限制范围物种，其中许多发生在珊瑚礁受到人类严重影响的地区，可能导致大量灭绝。受威胁的地方中心是主要的生物多样性热点，针对它们的保护工作可以帮助避免热带珊瑚礁生物多样性的丧失。
Coral reefs are the most biologically diverse of shallow water marine ecosystems but are being degraded worldwide by human activities and climate warming. Analyses of the geographic ranges of 3235 species of reef fish, corals, snails, and lobsters revealed that between 7.2% and 53.6% of each taxon have highly restricted ranges, rendering them vulnerable to extinction. Restricted-range species are clustered into centers of endemism, like those described for terrestrial taxa. The 10 richest centers of endemism cover 15.8% of the world's coral reefs (0.012% of the oceans) but include between 44.8 and 54.2% of the restricted-range species, Many occur in regions where reefs are being severely affected by people, potentially leading to numerous extinctions. Threatened centers of endemism are major biodiversity hotspots, and conservation efforts targeted toward them could help avert the loss of tropical reef biodiversity.
