Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 25. Diagnosis: 2 supraneural bones; scaleless, darkly pigmented blotch on dorsocaudal field of opercle; cuspidate oral jaw dentition; some or all teeth tricuspid in outer row oral dentition (Ref. 49597, 52307). Upper lip with crease (Ref. 49597). Spinous dorsal fin deeply excavated dorsally (Ref. 49597, 52307). Strongly marked oblique black bar anterior on body in preserved specimens; mouth small and slightly inferior (Ref. 49597).

Juveniles were collected with beach seine in the shallow inshore zone in a water depth of few centimeters, adults in deeper water; juveniles prefer shallow water riffles with medium current, while adults congregate around submerged tree branches and rocky outcrops (Ref. 49597). Mainly feeds on detritus, occasionally on insects and plants (Ref. 52307). Delayed uptake, ovophilic (Ref. 81260), larvophilic (Ref. 52307) mouthbrooder (Ref. 52307, 81260) that does not pair-bond (Ref. 52307), spawning in couples over open substrate (Ref. 49597). Female (rarely the male) incubates the fry (Ref. 49597, 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.4 ±0.20 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
