Warty venus (Venus verrucosa)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Venus verrucosa is a bivalve mollusc with equally sized valves that can grow up to 7 cm. It is beige to brown in colour with a white internal surface. The warty venus is characterized by a series of 20 or more prominent concentric ridges intersected by radiating grooves resulting in wart-like spines. Also, the escutcheon, the depression behind the umbones that encompass the external ligament, is much wider and semi-eliptical on the left valve and marked with transverse brown stripes.

Recorded distribution in Britain and Ireland

Most records are from the Shetland Isles and western Scotland, Wales and Ireland. Limited records on the east and south coast of England.

Habitat

Venus verrucosa is found partly buried in sand and gravel substrata. It is most commonly found from the low intertidal down to about 100 m.
