soft rays: 12. Body and head mottled with dark brown and buff; fin rays with dark brown or black spots; dark brown saddle blotch on top of caudal peduncle (Ref. 4315). Least interorbital width going 3.8-7.2 times in diameter of eye. Base of lower opercular spine concealed by scales. Anterior 1-3, usually 3, lateral line scales bearing a small spine. Iris lappet bearing short branches with bifurcate tips.

50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00367 - 0.01084), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic Level (Ref.
69278): 3.8 ±0.63 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
