Characterized by dark brown color with blue spots on head, body and fins; prolonged third dorsal spine, forms long filament in adult; longitudinal scale series 24; ctenoid scales; scaled cheek and opercle; corner of preopercle with single broad based spine, length about half of two-thirds pupil diameter; rounded caudal fin; depth of body 2.7-3.1 in SL (Ref. 90102).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00286 - 0.01390), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.45 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
