Recorded distribution in Britain and Ireland

CMU.BriAchi has a widespread but scattered distribution occurring in the presence of fine silts and clays. 'Brissopsis lyrifera - Amphiura chiajei' associations are recorded in the North Sea, off the Northumbrian coast, at the edge of the Celtic Deep, in the north-east and north-west regions of the Irish Sea and in some Scottish sea lochs.

Habitat preferences

Temperature range preferences - Data deficient

Water clarity preferences - No preference

Limiting Nutrients - No information found

Other preferences - High silt/clay sediment fraction.

Additional information

There is some doubt over records from the south coast. Holme (1961, 1966) inferred localized, usually inshore, occurrence of this community but with very few locations identified.
