Classification / Names Common names | Synonyms | Catalog of Fishes( genus , species ) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Triakidae (Houndsharks) > Triakinae
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 ) .

Short description Morphology | Morphometrics

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 ).

Biology     Glossary (e.g. epibenthic)

Recorded litter size litter sizes of 5-17 pups with size at birth likely to be around 28.0 cm TL (Ref. 124465 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 13.5 - 20.4, mean 16.5 °C (based on 27 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00224 (0.00105 - 0.00478), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.7   ±0.4 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Very high vulnerability (77 of 100).
