Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais (total) : 9; Raios anais : 10 - 11. Head smooth above (Ref. 2988). Maxillary barbel reaching middle of adipose fin in the young and the end of the rayed dorsal in the adult; nasal barbel reaching anterior border of eye (Ref. 52301, Ref. 2988). External mandibular barbels reaching the branchial fissure; occipital processus reaching the interneural bone (Ref. 52301). Longest dorsal fin ray a little longer than head; distance between adipose and dorsal fin equals base of the latter; adipose fin twice as long as the distance between dorsal and adipose fin (Ref. 2988). Caudal fin forked, upper lobe slightly the longer (Ref. 52301, Ref. 2988). Pectoral spine very strong, prominent and strongly serrated (Ref. 36900) on inner side (Ref. 2988). Pelvic fins under last dorsal fin ray (Ref. 52301, Ref. 2988).
Coloration: reddish brown above, yellowish white beneath and the caudal fin dotted with black (Ref. 36900, Ref. 2988).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00402 - 0.02604), b=2.95 (2.72 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.9 ±0.9 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Assuming Fec>10,000).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
