Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 10 - 11; Dorsale zachte stralen (totaal) : 17 - 18; Anale stekels: 2; Anale zachte stralen: 14 - 15; Wervels: 30 - 32. This species is distinguished by the following characters: with a rigid upper jaw lacking flexible lamina posteriorly, in adults extending about 0.7-1.2 eye diameters behind posterior margin of orbit; infraorbitals are relatively slender and tubular, the third infraorbital with small sensory canal opening and slender suborbital shelf; D X-XI,17-18, rarely X,18; vertebrae typically 12 + 18 or 19; body with two separate lateral lines, with the ventral one irregularly developed along lower side in region of anal-fin origin, often with one or more branches on belly; head covered with close-set, tiny, brown spots; pelvic and caudal fins usually strongly barred; anterior naris palmate (Ref. 128653).
Found in shallow reefs, in sand or rubble areas. Mouthbrooders (Ref. 240).

Estimates based on models
Preferred temperature (Ref. 123201): 25 - 29.2, mean 28 °C (based on 518 cells).
Fylogenetische diversiteitsindex (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).
Trofisch niveau (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
