The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Confined in Britain to the coasts of the Bristol Channel. An Atlantic species.
Old records from Tresco and Bude; most recently reported by Sir Eric Ansorge at Bude in 1923.
Habitat & Ecology
Lives around the tide line at the front of coastal sand dunes and feeds on sandhoppers.
Mechanical litter clearance from sandy beaches, which removes seaweed and driftwood as well as human debris.
Much of the more sensitive coastline is now protected by SSSI designations and
development is controlled by the Duchy of Cornwall.
