Spiny cockle (Acanthocardia aculeata)

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

Summary

Description

Acanthocardia aculeata has a solid, broadly oval, inequilateral shell, measuring up to 11.5 cm in length. The shell forms into 20-22 prominent radiating ribs, each of which carries a row of sharp spines down its centre. There are concentric rings covering the surface of the shell, which are well defined between the ribs. The shell margin is crenulate, with grooves extending throughout the inside of the valves.

Recorded distribution in Britain and Ireland

Recorded from Loch Ewe in north-west Scotland, off Scalby in north Yorkshire, in the vicinity of Brighton, in the Salcombe estuary and from the Isles of Scilly.

Global distribution

Recorded around the British Isles to the Mediterranean and northwest Africa.

Habitat

Only found in sublittoral muddy sands.

Depth range

0-50 m

Identifying features

  • Shell broadly oval, equivalve, inequilateral shell, beaks in front of the mid-line.
  • Angular outline, with almost straight posterior margin.
  • The right valve has 2 anterior lateral teeth and a single posterior tooth.
  • The anterior cardinal tooth in the left valve is larger than the posterior.
  • The left valve anterior tooth is larger than the posterior tooth of the right valve.
  • Concentric grooves on the shell surface.
