Description synthétique Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 4 - 5; Rayons mous dorsaux (Total) : 28 - 30; Épines anales: 2; Rayons mous anaux: 27 - 28. Distinctive humped back; horn only in adult males. A few scattered small dark-edged pale spots on postorbital head and body above pectoral fins. No white margin posteriorly on caudal fin. Profile of snout from mouth to eye strongly sloping, forming an angle of about 40° to horizontal axis of body (Ref 9808).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
Inhabits deep coastal, usually in small groups but occasionally in large schools (Ref. 48637). Sometimes solitary (Ref. 90102). An uncommon species found in seaward reef slopes (Ref. 9710, 48637), also along rocky shores (Ref. 30573). Feeds on benthic algae (Ref. 30573). Caught with nets (Ref. 30573).

Estimates based on models
Preferred temperature (Ref. 123201): 25.7 - 29, mean 28.1 °C (based on 218 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00818 - 0.02439), b=2.93 (2.78 - 3.08), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Niveau trophique (Ref. 69278): 2.7 ±0.29 se; based on food items.
Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.429; tmax=31).
Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
