Brachiopods and coralline sponges are the dominant taxa of a series of parallel pantropical communities found in cryptic habitats of Recent coral reefs, where these organisms may cover almost the entire available surface area. It is suggested that the continued survival and success of these and other groups of considerable paleontological importance resulted from their occupation of cryptic reef habitats after competition with more rapidly growing hermatypic corals in the Middle Jurassic when scleractinian reefs first appeared.
腕足动物和珊瑚海绵是一系列平行的泛热带群落的优势分类群，这些群落存在于现代珊瑚礁的隐蔽生境中，在这些生境中，这些生物可能覆盖了几乎全部可用的表面积。有人认为，这些生物和其他具有重要古生物学意义的生物群体的持续生存和成功，是由于它们在中侏罗世当石珊瑚礁首次出现时，与生长更快的有孔虫珊瑚竞争后，占据了隐蔽的珊瑚礁生境。
