Description

This biotope is found on mostly dead Solenosmilia variabilis framework and is characterised by dense growths of corals of many difference species including Isididae, Anthomastus grandiflorus, zoanthids, Antipathes sp., Leiopathes sp., Stichopathes sp. and gorgonians. It is associated with steep topography on radial ridges and parasitic cones. These mixed coral assemblages appear to provide a suitable habitat for a diverse range of fish including the false boarfish Neocyttus helgae, Lepidion eques, and orange roughy Hoplostethus atlanticus.
