Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal soft rays: 28 - 36. Diagnosis: pectoral-fin spines denticulate; 28-36 branched anal-fin rays; 5-9 gill rakers on lower limb of first gill arch; only one pair of mandibular barbels; palatine teeth present (Ref. 57127). Coloration: in live as well as in preserved specimens, head and back brown; dark brown mid-lateral band runs from just behind eye to hind margin of caudal fin; short second lateral band begins above pectoral-fin base and runs obliquely backwards to above anal-fin base; both caudal-fin tips with a dark brown, more or less elongate spot; dorsal fin, pectorals and pelvics unpigmented (Ref. 57127).

Oviparous, eggs are unguarded (Ref. 205). Max. size 81mm total length (Ref. 3570).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00465 - 0.01707), b=3.03 (2.86 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec=100).

Vulnerability (Ref. 59153): Low vulnerability (18 of 100) .

Price category (Ref. 80766): Unknown.
