Summary

Description

A small, yellowish-white, obliquely oval cockle up to 13 mm in length. It has 24-26 radiating ribs, anteriorly bearing blunt scales and posteriorly bearing small spines. In the middle region the ribs are smooth. The concentric ridges are poorly developed. The right shell valve has two anterior teeth and one posterior lateral tooth whilst the left valve has only one anterior tooth and one posterior lateral tooth. The margins of the valves have deep crenulations with grooves on the inner surface extending a long way in from the margin towards the beak. The inner surface is a glossy white.

Recorded distribution in Britain and Ireland

Occurs on British and Irish coasts where suitable muddy, sand and gravel substrata are present.

Global distribution

Occurs from Iceland and the coast of Murmansk south to the Iberian Peninsula, into the Mediterranean, and along the Atlantic coast of Morocco and the Canary Islands.

Habitat

Parvicardium ovale burrows in sublittoral muddy sand and gravel substrata at depths of 3 to 100 m.
