Short Description
Original diagnose after Compagno, 1984 [517]: Field Marks: A very stout houndshark with a short, broadly rounded snout, lobate anterior nasal flaps that do not reach the mouth and are far separated from each other, long upper labial furrows that reach the lower symphysis of the mouth, teeth not bladelike, with straight erect cusps and cusplets little-developed or absent, broad fins with the pectorals broadly falcate and the first dorsal fin with a posteriorly sloping posterior margin, and usually with numerous black spots.
Diagnostic Features : Strong erect cusps on teeth of the middle two-thirds of the dental band, the more distal teeth having no cusp or weak ones, cusplets low or absent on almost all teeth, teeth semimolariform but not bladelike. First dorsal fin with posteroventrally sloping posterior margin; pectoral fins broadly falcate in adults. Total vertebral counts 164 to 170. Body usually with numerous small black spots, sometimes plain-coloured (plain females may have spotted young).

Distribution
Eastern Pacific: Galapagos Islands and from Peru to northern Chile. Mexican records of this species are erroneous. Source: www.gbif.org

Human uses
fisheries: minor commercial; price category: high; price reliability: very questionable: based on ex-vessel price for species in this family

Biology
Ovoviviparous, embryos feed solely on yolk [733]. Found on the continental shelf, mostly inshore. Possibly to 240 cm. Probably feeds on benthic invertebrates.
