ME1-212 - Assemblage de Dallina septigera sur roche du bathyal supérieur en Atlantique

Dallina septigera assemblage on Atlantic upper bathyal rock

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Biotope dominated by the brachiopods Dallina septigera and Macandrevia cranium. Brachiopod dominated assemblages have been observed from multiple locations with the UK deep-sea occuring on bedrock, bedrock with a sand veneer and mixed substrates. Previous observations have been made in the high current areas on the Wyville-Thomson Ridge and summit of the Anton-Dohrn Seamount, but also on Hatton Bank, Rosemary Bank Seamount, Dangaard and Explorer Canyons and the warm shallow regions of the Wyville-Thomson Ridge and Faroe-Shetland Channel. This assemblage was also identified in the mid bathyal, but the associated species are likely to differ. Characterising species listed refer to all Dallina septigera and Macandrevia cranium assemblages not just those found associated with the zone and substrate specified in this biotope.
