Morphology | Morphometrics
(total): 5-6. This species is distinguished by the following characters: ventral surface fully naked and interspaces of principal bucklers on dorsal surface lacking dermal spinules: D 5-6 (mainly 6); pectoral-fin rays 13; blunt subopercular buckler with a stout anterior-directed spinelet usually present; rostral spine directed rather more upward than forward; relatively few and loosely arranged bucklers; all bucklers are blunt; appressed anal fin reaching caudal fin base; it is the smallest species of the genus reaching 51.1 mm SL in adults (Ref. 92977).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 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), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
