New record of the Critically Endangered striped smooth-hound, Mustelus fasciatus (Garman, 1913) (Chondrichthyes, Triakidae), in the Southwest Atlantic

Abstract

We report the southernmost known occurrence in the Atlantic Ocean of the striped smooth-hound, Mustelus fasciatus (Garman, 1913). The shark, a female measuring 106 cm TL, was fished in warm coastal waters, with a salinity of 33,189 PSU, of central Argentina (40°52ʹ13ʺ S, 062°18ʹ42ʺ W). This report increases by 205 km southward the known range of this endemic and Critically Endangered species.
