Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 10 - 12; Anal spines: 3; Anal soft rays: 8 - 10; Vertebrae: 28 - 29. Diagnosis: mouth strongly upturned, making an angle of about 50° with the horizontal; outer row jaw teeth reduced and few in number, inner row teeth minute tricuspids; lower pharyngeal jaw markedly longer than wide, with a reduced dentigerous surface, and covered with a ‘felt’ of tiny unicuspid teeth (Ref. 81260).
Prefers open water regions at greater depths, but ventures into the more shallow areas of the lake for spawning, which normally occurs during the rainy season; mainly feeds on phytoplankton and small insects; probably ovophilic mouthbrooder; males occupy a tertitory of ca. 50 cm and it is often possible to find large numbers of males in a limited area (Ref. 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=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 2.6 ±0.28 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).
