Cornish Red Data (2009)

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.

Acroloxus lacustris - Lake Limpet



Range & Status

This small limpet lives on aquatic vegetation and is usually associated with rich faunas in slow-moving hardwater habitats. It is common in much of Britain, but was not discovered in Cornwall until 2006 when it was found by Tim Geatches of the Environment Agency in the River Camel (SX06N). Two additional sites have since been found, both in SX06B, a pond at the edge of Retire Common and close by in a pond at Lakeview Country Park. Its softwater habitats in Cornwall are atypical, especially the site in the River Camel which is a fast-flowing, soft-water river with very sparse aquatic vegetation.
