Etymology: Cynolebias: Greek, kyon = dog + Greek, odous = teeth + Greek, lebias = a kind of small fish (Ref. 45335).
More on author: Steindachner.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; non-migratory. Tropical; 22°C - 30°C (Ref. 13614)
South America: São Francisco river floodplain in Brazil.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 27139)
Dorsal soft rays (total): 14 - 18; Anal soft rays: 18 - 22; Vertebrae: 33 - 37. Differs from all species of Cynolebias by having the upper jaw ventrally displaced (Ref. 97357). Snout gently pointed with lower jaw not elongated; scaled anal-fin base; caudal and pectoral fins rounded (Ref. 40938).
Inhabits river floodplain (Ref. 97357). Bottom spawner, 5-7 months incubation. Is very difficult to maintain in aquarium (Ref. 27139).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
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).
