Sagartiogeton undatus and Ascidiella aspersa on Atlantic infralittoral sandy mud

Description (English)

Sheltered sublittoral mud or sandy mud in shallow water with relatively few conspicuous species may be characterised by the anemone Sagartiogeton undatus in low numbers and the tunicate Ascidiella aspersa. Other taxa may include Carcinus maenas, Pagurus bernhardus and terebellid polychaetes. The burrowing anemones Cerianthus lloydii may also be found occasionally. The status of this biotope is uncertain at present as it is not known whether it is an impoverished, disturbed or epifaunal variant of other sheltered, shallow mud biotopes such as MB6-249 or if the areas in which it has been recorded have been incompletely surveyed.
