Head and body brown; relatively large, black branchial blotch from mid-gill slit to rear border of eye; dusky blotch around eye continued onto forehead and around spinous dorsal base; dark brown iris; pale dusky brown lips. Large pelvic fin rudiment, narrowly attached to posterior margin of ventral flap. Midbody scales with 1-7 spinules, not closely packed; elongate spinules on posterior half of body. Scale spinules on posterior half of body of male very prominent, scale ridge rugosities developing at about 55-65 mm SL.

Estimates based on models

Preferred temperature (Ref. 123201): 25.5 - 29.4, mean 27.9 °C (based on 120 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00943 - 0.04220), b=2.93 (2.75 - 3.11), in cm total length, based on LWR estimates for this (Sub)family-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).
