Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 15 - 24; Anal soft rays: 20 - 25; Vertebrae: 28 - 30. Caudal peduncle of female with black spots. Male's anal fin with gray to black distal stripe; basihyal broad, 70-95% in length; and, second pharyngobranchial teeth, 5-10. Dorsal-fin rays 20-24 in male, 15-19 in female; anal-fin rays 21-25 in male, 20-24 in female; caudal-fin rays 23-25, caudal fin subtruncate in male, rounded in female.

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=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±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).
