Aulacomya atra is native in South America - in Peru, Chile (where it grows up to 170 mm in length), the Falkland Islands and Argentina.[2] It is also found on the coasts of New Zealand and Southern Africa, from Namibia to Port Alfred, South Africa, from the intertidal to 40 m.[2] Introduced specimens have been found in Moray Firth, Scotland, Europe.[3]In Southern Africa the species grows up to 90 mm in length. It usually lives in crowded intertidal beds. Individual animals have brown ribbed shells, which darken to black with age.[4] References1. ^1 2 Bouchet, P.; Gofas, S. (2011).
