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); palumbes: Latin for wood-pigeon or ring-dove, referring to its dove-gray coloration (See ETYFish).

خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. A smoothhound with lines or scatterings of small white spots along body (Ref. 5578). Grey above, white below (Ref. 5578).
Found on the continental shelf and upper slope from the intertidal region to deeper waters over sand and gravel bottoms (Ref. 244). Feeds on crustaceans, octopi, bony fish, and fish offal (Ref. 5578). Ovoviviparous (Ref. 50449). Catch usually discarded but may be utilized in a local fishery that processes sharks into jerky (Ref. 244).
