Chthamalus fragilis
Taxonomic Group: Crustaceans-Barnacles
Common name: LITTLE GRAY BARNACLE

Overview:

Chthamalus fragilis is a small grey barnacle (up to 9 mm in size) first described from Charleston, South Carolina. Its native range extends from New Jersey to Mexico. It is introduced in Southern New England and is found from Long Island Sound to Cape Cod. The northern range limit of C. fragilis appears to be set by temperature and competition with the barnacle Semibalanus balanoides. In its native range C. fragilis is found on a wide range of habitats, including marsh grasses and rock, but in its introduced range it is limited to the upper rocky intertidal. There are no reported impacts of C. fragilis from its introduced range.
