Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

This large species of Squalus of the ‘mitsukurii group’ is distinguished by the following set of characters: body is relatively slender, trunk height 8.7-12.4% TL (mean 10.1% TL); snout angular and short to moderate in length, its mouth width 1.35-1.60 (1.48) times horizontal prenarial length and pre-oral length 1.92-2.06 (1.97) times the prenarial length; pre-first dorsal length 30.3-31.5 (30.2)% TL; pre-second dorsal length 63.6-67.0 (65.5)% TL; interdorsal space 26.7-30.0 (28.6)% TL; pelvic-caudal space 25.2-29.3 (27.1)% TL; dorsal fins relatively small and upright; first dorsal fin length 11.4-12.8 (12.2)% TL, height 6.5-7.8 (7.3)% TL, with inner margin length 4.9-5.7 (5.4)%% TL; second dorsal fin length 10.6-11.7 (11.1)% TL, its height 4.0-4.6 (4.4)% TL and inner margin length 4.3-4.9 (4.6)% TL; first dorsal fin spine length 46.6-64.6 (55.6)% of first dorsal fin height; second dorsal spine length 104.5-114.5 (109.0)% of second dorsal fin height; caudal bar triangular, extending from caudal fork nearly to the anterior edge of the lower caudal, distinct upper caudal blotch and fringe present in juveniles, upper caudal blotch diffuse in adults but extending to posterior margin of the upper caudal fin, the upper and lower caudal fins white tipped; flank denticles tricuspid; teeth similar in appearance in upper and lower jaws, numbers ranging from 26-28 in the upper jaw and 23 in the lower; monospondylous centra 41-42, precaudal centra 85-89, total centra 112-116 (Ref. 126986).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00339 (0.00162 - 0.00707), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.4 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Preliminary K or Fecundity.).
