Dosinia exoleta is not listed under any importance categories.
|Phylum||Mollusca||Snails, slugs, mussels, cockles, clams & squid|
|Class||Bivalvia||Clams, cockles, mussels, oysters, and scallops|
|Recorded Distribution in Britain and Ireland||Common off the coasts of Britain and Ireland but there are no records from the south east coast of England.|
|Habitat information||This species burrows in muddy gravel or shell gravel on the lower shore to depths of about 100 m.|
|Description||The shell is solid and almost circular in shape overall. White, yellow-ish, or light brown in colour with irregular rays, streaks, or blotches of darker brown or pinkish brown. Can grow up to 6 cm in length. The umbones are small but distinct with the contour of the shell concave on one side of the umbo and convex on the other. When closed the valves form a heartshaped lunule situated in front of the beaks and recognisable from the rest of the shell due to the change in sculpture which exhibits very fine radiating ridges.|
|Additional information||This species is also known as the rayed Artemis and is very similar to the smooth Artemis Dosinia lupinus. The smooth Artemis has more concentric ridges than the rayed Artemis and as the name suggests, a smoother shell. Dosinia exoleta is slightly larger than Dosinia lupinusand the anterior margin of its shell is more arched.|
