soft rays: 4;
Vertebrae: 18 - 20. Entire body covered with simple, very small, and thickly distributed tubercles Cephalic lateral-line counts: subopercular usually 6, (5-7); preopercular, 3 (1-4). Tail lateral-line counts 9-15. Subopercular spines small, inconspicuous. Paired fins with tubercles covering pedicels and occurring along both dorsal and ventral surfaces of fin rays.

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01958 (-0.19741 - 0.23658), b=2.96 (2.84 - 3.07), based on LWR estimates for this family-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100) .
