Morphology | Morphometrics
(total): 14 - 16;
soft rays: 7 - 8. Diagnosis: lower pharyngeal jaw robust and massive, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth; mouth not squared or obtuse; ventral margin of lower lip smooth; ratio of lower jaw length to lower jaw width > 1; oral jaw teeth fixed with non-spatulate crowns (Ref. 26738, 81260). 13-16 gill rakers on first arch (Ref. 26738).
Prefers sponges, but small amounts of diatoms, plants (mostly algae) and detritus have also been found in their stomachs (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307). Usually spawns in shallow waters, building colonies of up to 6 pairs separated by about 30 cm; eggs are hidden between leaves and pieces of wood (Ref. 52307).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00520 - 0.04832), b=2.99 (2.74 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.1 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
