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);  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.

Biologie     Glossaire (ex. epibenthic)

Found on the continental shelves and uppermost slopes, from the intertidal region to at least 350 m depth (Ref. 244). Collected to depth of 624 m in the eastern Ionian Sea (Ref. 56504). Sometimes in midwater but prefers to swim near the bottom (Ref. 244). Feeds mainly on crustaceans, but also cephalopods and bony fishes (Ref. 244). Viviparous, with a yolk-sac placenta (Ref. 244). Taken by shore and ski-boat anglers (Ref. 5578). Utilized for human consumption, oil, and fishmeal (Ref. 244). Sexual maturity is reached at a length of 70-80 cm (Ref. 35388).
