Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN]. (See ETYFish); henlei: In honor of Friedrich Gustav Jacob Henle (1807-1885), German physician, pathologist and anatomist, who, along with Johann Müller, produced the first authoritative work on sharks (1839-1841). (See ETYFish).

Max length : 100.0 cm TL hane/ej könsbestämd; (Ref. 31395); rapporterad maxålder: 13 år (Ref. 6098)

Adults are found on the continental shelves from the intertidal region to at least 200 m depth. They feed on crabs, ghost shrimps, mantis shrimps, isopods, squids, polychaete worms, tunicates and small bony fishes. Viviparous (with a yolk-sac placenta), with 3 to 5 young in a litter. Size at birth between 19 and 21 cm. Readily kept in captivity. Utilized for human consumption. Marketed fresh, smoked and frozen (Ref. 9987).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

Viviparous with a yolk-sac placenta; with 3 to 5 young in a litter. Size at birth ranges from 19-21 cm (Ref. 244). Distinct pairing with embrace (Ref. 205). Polyandry is a common life history strategy among the elasmobranchs and for M. henlei, the occurrence and frequency of polyandric behavior may vary depending on location and density of breeding individuals (Ref. 95902).
