Scleraxonia

Scleraxonia is a suborder of corals, a member of the phylum Cnidaria.[1]

Characteristics

Members of Scleraxonia have a skeletal axis made of calcified spicules, organic fibres or both, which may be separate, linked or fused together.[2]

There are nine recognised families in this suborder and over thirty genera, with four families (Anthothelidae, Briareidae, Coralliidae and Subergorgiidae) containing some deep-water species and two families (Paragorgiidae and Parisididae) being exclusively deep water.[3]
