Aulacomya atra is featured here because it has been found in the UK. It is listed as a UK non-native species because it was found on the Moray Firth in Scotland during 1994. I do not know if it has been found more than once, or if it still persists.

Specimen shown is 86mm in length and from the authors collection of non-native marine molluscs. This particular specimen was collected by a fisherman on 21.12.02 at San Antonio Oeste, Rio Negro Province, Argentina where the species is native. Specimen photographed by author, 25.07.18.

Scientific and European Names:
Aulacomya atra, Mytilus crenatus, Magellan Mussel, Cholga Mussel, Ribbed Mussel.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
