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); stevensi: In honor of John Stevens (b. 1947), Senior Principal Research Scientist, CSIRO Marine and Atmospheric Research (Australia), who has “dedicated a lifetime to researching sharks around the world, and who has contributed greatly to our knowledge of sharks and rays in Australia” (See ETYFish).
Eponymy: Dr John Donald Stevens (d: 1947) is a biologist and ichthyologist who was a Senior Principal Research Scientist with CSIRO Marine and Atmospheric Research, originally in Sydney (1979–1984) and subsequently in Hobart, Tasmania, Australia (1984–2011). [...] (Ref. 128868), visit book page.

Description synthétique Clés d'identification | Morphologie | Morphométrie
This moderately large species is disinguished by the following characters: palatine processes of the
palatoquadrates not subdivided at the symphysis; pre-second dorsal length 58.1-61.4% TL; upper labial furrows are longer than lower furrows, upper ones 1.7-2.3% TL and 1.3-1.7 times lowers; buccopharyngeal denticles cover entire tongue and roof of mouth; reproductive mode aplacental viviparity; adults are without any hypercalcification of skeletal elements; dorsal fins moderately large and upright, first dorsal-fin anterior margin 13.0-15.7% TL, height 8.5-10.3% TL; claspers of adults are moderately long, inner length 8.1-11.2% TL; teeth in about 72/75 files; precaudal vertebral centra 75-91, monospondylous centra 33-41; small white spots usually present on the dorsal surfaces of body, including along lateral line; dorsal fins often with dark apical margins; caudal-fin terminal lobe white tipped (Ref. 124465).
Body shape (shape guide): elongated; Cross section: oval.
Body shape (shape guide): elongated; Cross section: oval.
Recorded litter size litter sizes of 5-17 pups with size at birth likely to be around 28.0 cm TL (Ref. 124465).
