soft rays: 11 - 12;
Vertebrae: 27. This species which occur from deep reefs have two anal-fin pterygiophores anterior to the first haemal spine; have an extensively scaled body; high anal-fin ray count; with papillae rows 5i and 5s connected as a single row (Ref. 113825).
Occurs in deep reefs (Ref. 113825).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00465 - 0.02254), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 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).
