Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 14 - 16; Rayons mous dorsaux (Total): 10-11; Épines anales 3; Rayons mous anaux: 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.

50 = 0.5000 [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).
Niveau trophique (Ref.
69278): 2.8 ±0.1 se; based on size and trophs of closest relatives
Résilience (Ref.
