Description
This broad community contains assembages where crinoids dominate the fauna. Crinoid assemblages are found typically in areas with higher current speeds that facilitate filter feeding, such as the shelf edge. The crinoid species Heliometra glacialis has been recorded on Arctic mid bathyal rock.
