Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 16 - 17; Épines anales: 3; Rayons mous anaux: 14 - 16. Black spot on upper half of dorsal fin from sixth or seventh to ninth spines. Males have long, upcurved extension of maxillary bone marked with black bands (Ref. 26938). Females appear to lack the long double-banded maxilla, and there is only a single blackish band at the corner of the mouth (Ref. 13442).

Inhabits sandy bottoms near coral reefs (Ref. 9710). Feeds on gastropods, crabs and fishes (Ref. 13628). Monogamous (Ref. 52884). Oviparous, mouthbrooding by males (Ref. 205).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884). Males incubate the eggs in the mouth (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 25.3 - 28.1, mean 27 (based on 180 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.6 se; based on diet studies.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Catégorie de prix (Ref. 80766): Unknown.
