Morphology | Morphometrics
Vertebrae: 148 - 152. This species is characterized with its tail much longer than head and trunk, distance from tip of snout to anus 2.9-3.1 in TL; posterior nostril close to edge of orbit; dorsal fin origin over basal half of pectoral fins; a single row of conical teeth at side of jaws, compressed fore and aft, close-set, forming a shearing edge; colour brownish gray with a black band between upper lip and eye (absent in juveniles less than about 20cm long); median fins with distinct black margin; pectoral fins often with a large blackish area; dark gray to black bars are seen at night (Ref. 86689).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00049 (0.00022 - 0.00111), b=3.23 (3.05 - 3.41), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (67 of 100) .
