A small dogfish with a short, angular snout and a small mouth almost as wide as the snout is long; body without spots; 1st dorsal fin spine over pectoral fins [536]. Bronze-grey above, white below; dorsal fins with black tips and white edges but markings inconspicuous in adults [536].

Distribution
Eastern Indian Ocean: appears to be an Australian endemic. Dogfishes presently referred to in current literature as Squalus megalops appear to belong to a complex of similar species. Specimens from the different regions still need to be compared carefully [1388]. Source: www.gbif.org
