Water depth zonation of fifty nine benthonic foraminiferal species in marine sediment surfaces has been described. Some species are combined to groups which mark particular depth zones: an upper and lower shelf-fauna, an upper and lower slope fauna, and a shelf-slope fauna.Dependence on latitude could be ascertained for Textularia panamensis, and submergence effects for Hyalinea balthica.
