Short Description
Original daiagonis after Springer [3013]: Similar in form to Mustelus canis but males reaching maturity at a small size (600 mm or less). Snout narrower. Fins broad; lower lobe of caudal not strongly developed, not acute; origin of the first dorsal in advance of the inner angle of the pectoral. Eyes smaller than in M. canis (horizontal diameter of orbit 2.5 percent of total length in average of five specimens as compared with 3.1 percent average for M. canis of comparable size); horizontal diameter of orbit greater than distance between the nostrils. Mouth broadly arched and rounded anteriorly in the adults; outer labial fold longer. Teeth paved, crowns not elevated in adults; accessory cusps present on the teeth of the young specimen, not on the adults examined. Dermal denticles similar in structure on the fiat surfaces of the body, typical 4-ridged, mth ridges reaching about two-thirds of the distance to the posterior apex. Color uniform gray, without Hght or dark spots or bands.
