Short description Identification keys | Morphology | Morphometrics

This species is distinguished from its congeners by the following set of characters: presence of a postdorsal ridge; postdorsal ridge plates (11-16, modally 12 vs. 8-11, modally 9); absence of keels on dorsal and mid-dorsal series of plates; dorsal profile of the head rounded; premaxillary (47-73); unicuspid teeth; dentary (42-78); snout profile rounded, snout tip naked; single fenestra on the anterior portion of pelvic girdle; vertebrae (31 vs. 29); absence of a cluster of abdominal platelets between the pelvic fins; tip of pectoral-fin spine reaching the second third of dorsal-fin base when adpressed; absence of dark spots over dorsal and lateral surfaces of head, body and fins; posterior margin of lower lip fringed; and five infraorbitals (Ref. 138661).
Body shape (shape guide): elongated.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00977 (0.00436 - 0.02192), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience
(Ref. 120179) 		High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Low vulnerability (10 of 100). 🛈
