Max length : 110 cm TL male/unsexed; (Ref. 244); 120.0 cm TL (female); max. reported age: 15 years (Ref. 9031)
Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri Northwest Pacific: China, Taiwan, Korea, and Japan. Nominal records from Ambon, Indonesia (unconfirmed and based on a specimen close to if not identical to Hemitriakis abdita) and New Caledonia.
Epibenthic: Occurs close inshore and offshore down to at least 100 m depth. Presumably feeds on small fishes, cephalopods and crustaceans. Ovoviviparous, with 8 to 22 young in a litter. Size at birth about 20 to 21 cm. Utilized for human consumption.
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae: Ovoviviparous, embryos feed solely on yolk.
