Hygrosoma petersii, Benthothuria funebris and Oneirophanta assemblage on Atlantic abyssal mud
Description (English)
This biotope consists of assemblages dominated by holothurians Benthothuria funebris and Oneirophanta with echinoderm Hygrosoma petersiion mud. Gage (1986) describes this assemblage from his deepest station in the southern Rockall Trough at 2900m on pelagic ooze. No other detail are available on this assemblage and it is possible that it may represent a transitional assemblage between the Acanella arbuscula assemblage (found shallower) and the abyssal Psychropotes longicauda and Oneirophanta mutabilis assemblage found deeper. This assemblage has been described based on literature only.
