Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

This species is distinguished from its congeners by the following set of characters: body brownish or greyish with a narrowly wedge-shaped disc; a long narrow bluntly pointed snout (angle 31-40°); broad oblique nostrils with the narrow anterior opening; nostrils about half of the mouth width, subequal (0.98-1.33) to internasal width; ~55-57 nasal lamellae; anterior nasal flaps are slightly penetrating into internasal space, their interspace 2.20- 2.61 in length of the posterior nasal aperture; in adults the orbit is very small, diameter 8.19-11.62 in preorbital length, 2.25-2.69 in interorbital space; rostral ridges are almost joined along their entire length; margin of cranium sharply demarcated before eyes; spiracular folds are very short and widely separated; rough skin densely covered with small denticles, more coarsely granular on the dorsal surface than ventrally, enlarged between orbits and in a distinct band between nape and first dorsal fin; tail relatively longer, its length 1.15-1.48 in disc length; dorsal fins narrowly spaced, interspace 1.32-2.11 in base length of the first dorsal fin; clasper length in adult male 4.37-5.70 in total length (Ref. 125646).

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=0.00389 (0.00141 - 0.01074), b=3.05 (2.82 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).
