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); manazo: Japanese vernacular for this shark (See ETYFish).

Found in the intertidal zone, on mud and sand bottom, down to a depth of at least 360 m (Ref. 13563). May also be found in semi-enclosed sea areas (Ref. 11230). Feeds mainly on bottom invertebrates, also bony fishes (Ref. 244). Ovoviviparous (Ref. 50449). Caught regularly by demersal longliners operating both inshore and in deep-water (Ref.58048). Utilized for human consumption (Ref. 244).
Ovoviviparous, embryos feed solely on yolk (Ref. 50449), with 1 to 22 (Ref.58048 reports 5-14)young in a litter. Gestation period takes about 10 months (Ref. 244) or 11-12 months (Ref. 28055). Young born in spring. Distinct pairing with embrace (Ref. 205).
