Short Description
Original diagnose after Compagno, 1984 [517]: Field Marks: A moderately slender 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 partially bladelike, with strong, erect to oblique cusps on all teeth and well-developed cusplets, relatively narrow fins, and scattered black spots.
Diagnostic Features : Teeth with strong cusps and cusplets on almost all teeth, not semimolariform, lateroposterior teeth bladelike, with strongly oblique cusps. Pectoral fins broadly triangular in adults. First dorsal fin with nearly vertical or posteroventrally sloping posterior_ margin. Total vertebral counts 149 to 155. Body with sparsely scattered small black spots and broad dusky saddles in young, spots fading and sometimes absent in adults

Distribution
Northwest Pacific: southern Siberia to Taiwan [517]. Nominal records from the Philippines [544]. 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 and insular shelves, often occurring in shallow water close inshore. Prefers estuaries and shallow bays, especially sandy and algal-covered areas and eelgrass flats. Feeds on small fishes and probably crustaceans and other benthic invertebrates. Often solitary, though some may cluster in resting areas on bottom [517][17641]
