3. Artemisina transiens aggregation on circalittoral rocky bottom DESCRIPTION: This species create aggregations from 35 m to 120 m depth, always on rocky seabed. Although OCEANA found these fields of Artemisina transiens on rocky seabed covered by a layer of sediment in the deepest areas, in the rest of its distribution range it predominates on non sedimentary rocky seabed. This sponge has been recorded making up dense aggregations in several locations in Galicia and Asturias, but not in the eastern zone of the Biscay Gulf. Making part of this community and covering the substrate, it is common to find Corynactis viridis and/or brachiopods. Mixed with these aggregations, large facies of sponges (Axinella dissimilis, Axinella polypoides, Cliona celata¸Tedania urgorrii) and gorgonians (Eunicella verrucosa) can be found, while echinoderms (Echinus esculentus, Holothuria forskali) do not create large groups, although they are also abundant. Dendrophyllia cornigera and Phakellia ventilabrum appear so abundantly on some areas of the known distribution of Artemisina transiens (Cantabrian occidental shelf) making up mixed fields with this species.
