Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 7; Raios dorsais (total) : 9; Espinhos anais: 1; Raios anais : 9 - 10. This species is distinguished by the following characters: pectoral rays 15; upper jaw with numerous teeth (21-26); less lateral scale series (14-29) and zigzag series (11-14); second dorsal fin in females long; caudal peduncle short; head blackish, dorsally with blackish band extending from the tip of snout and upper lip, under the eye to the posterior edge of operculum and pectoral base; blackish band extends from the back of the eye to the dorsal part of pectoral fin base and to caudal fin along midline (Ref. 85524).
Body shape (shape guide): fusiform / normal.
This species is found in clear, high gradient streams with rocky bottom. It lives on the bottom, on top of rocks, and often seen swimming in open water in the current between rocks or in large pools. Like its congeners, it is presumed to spawn in freshwater, the free embryos drift downstream to the sea where these undergo a planktonic phase, and before returning to the rivers to grow and reproduce (Ref. 85524).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref.
