MG6-211 - Assemblage d'Hygrosoma petersii, Benthothuria funebris et Oneirophanta sur vase de l'abyssal en Atlantique

Hygrosoma petersii, Benthothuria funebris and Oneirophanta assemblage on Atlantic de l'abyssal mud

Classification des habitats EUNIS 2022

Descriptif de l'habitat

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 de l'abyssal Psychropotes longicauda and Oneirophanta mutabilis assemblage found deeper. This assemblage has been described based on literature only.
