Comparative depth distribution of corallimorpharians and scleractinians (Cnidaria: Anthozoa)
We assessed whether CaCO3 concentration of seawater may be relevant to the occurrence of members of Corallimorpharia and Scleractinia, which are very similar except for the possession by scleractinians of a calcareous skeleton. In collections of both the Challenger Deep-sea Expedition 1872–1876 and...

We assessed whether CaCO3 concentration of seawater may be relevant to the occurrence of members of Corallimorpharia and Scleractinia, which are very similar except for the possession by scleractinians of a calcareous skeleton. In collections of both the Challenger Deep-sea Expedition 1872–1876 and the US Antarctic (Research) Program, average depth of occurrence was significantly greater for corallimorpharians than for scleractinians. We also compared depth of occurrence relative to the position of the aragonite saturation horizon (ASH) at many localities from which specimens were collected. Nearly 25 and 50% of stations at which scleractinians were collected were below the ASH for the Antarctic and Challenger stations, respectively; 50 and 100% of the Antarctic and Challenger stations at which corallimorpharians were collected were below the ASH, respectively.
