Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 26. This species differs from its congeners in having the following characters; its large size (largest 3.68 cm SL); predorsal scales 10-12; second spine of first dorsal fin elongate (not filamentous) or not elongate; pectoral fin branched, middle 6-11 rays; fifth pelvic-fin ray unbranched or branched, 49-57% of fourth ray in length; connecting membrane absent between innermost pelvic-fin rays; presence of a deep interorbital trough, no postorbital trough; pectoral fin rays 18-19; longitudinal scales 24; cheek and opercular scales; ground color of head and body grayish brown dorsally, dull yellow to pale ventrally; body when fresh with seven grayish lavender saddles with broad pale pink margins (Ref. 75857).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), 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).
