Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 11; Anal soft rays: 10; Vertebrae: 33. Distinguished by the following combination of characters: absence of mandibular canal pore W; long epiotic processes in adults, extending beyond the first vertebra; anal-fin with 10 rays; discontinuous midlateral and dorsolateral stripes formed by series of blotches on body; midlateral stripe discontinuous anterior to dorsal-fin origin; large third hypobranchial, greater than one-half the length of the second hypobranchial; and presence of teeth on fourth ceratobranchial of adults (Ref. 75966).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
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).
