Autecology of shallow-water Octocorallia from Mediterranean rocky substrata, II. Marseille, Côte d’Azur and Corsica

Qualitative sampling of Octocorallia in 226 underwater stations at 23 localities between Marseille and Sardinia yielded information about their tolerances with respect to depth, slope, sediment and relative irradiance. The results are confronted with those previously obtained for the Banyuls area, and some conclusions are drawn regarding the existence of typical habitat-induced Octocorallian communities.
