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 Leptometra celtica is recorded in the Atlantic upper and mid bathyal. Associated species are likely to differ with depth and substrate type.
