Short description
Morphology | Morphometrics
Dorsal
spines
(total): 1. Diagnosis: large species, up to 300 mm SL or more; anterior nostrils never closer to each other than the posterior ones; inner margin of pectoral-fin spine finely denticulate; 39-70 branched anal-fin rays; 8-15 gill rakers on lower limb of first gill arch; adipose fin always present (Ref. 57127).
Coloration: head and back dark brown; brownish lateral bands above and below lateral line, above and along anal-fin base, and along anal-fin margin; dorsal fin, pectorals and pelvics yellowish, the first two often mottled (Ref. 57127).
Feed mainly on terrestrial insects (Hymenoptera, Hemiptera, Coleoptera) washed into the water and on mayfly larvae (Ref. 6868). Oviparous, eggs are unguarded (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00400 - 0.01440), 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): 3.4 ±0.49 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Assuming fec > 10,000).
Vulnerability (Ref.
59153): Low to moderate vulnerability (29 of 100) .
