Morphology | Morphometrics
This species is distinguished by the following characters: fine reticulate color pattern on dorsal surface (uniformly brown or creamy white in some preserved specimens); eye large, 12.5-14.9% SL; interorbital space narrow, 4.4-6.1% SL, forming a groove; rostral protuberance short and blunt, directed upward; principal bucklers blunt and relatively few in number, naked between principal bucklers; no buckler dorsal to orbit; ventral surface with few small bucklers forming a large naked area; subopercular buckler with 1 spine directed forward; relatively small adult body size (< 70 mm SL) (Ref. 84006).

Estimates based on models
Preferred temperature (Ref. 123201
): 8.7 - 14.5, mean 9.1 °C (based on 3 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
