Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 13 - 15; Espinhos anais: 0; Raios anais moles: 18 - 22; Vértebras: 42 - 45. Diagnosis: Body slender, its depth about 20-24% of standard length; scutes strongly keeled, beginning under pectoral fin base, with 10-15 pre-pelvic and 8-11 post-pelvic scutes; snout rather blunt or acute; lower jaw not or slightly projecting, included in upper when mouth closed, with small teeth limited to anterior part; pre-maxillae with a single row of 24-42 small conical teeth directed inwards; maxilla slender, its blade more than 3 times as long as deep, upper edge quite strongly ridged; posterior supra-maxilla slender, spatulate, with distinct anterior shaft, shaft longer than blade; lower gillrakers 17-24 (Ref. 188, 47399). Also characterized by 26-35 scales in a longitudinal series and anal fin with 18-22 rays (Ref. 47399). It differs from Microthrissa moeruensis in having a distinctly blunter snout and less scales in longitudinal series (Ref. 188, 47399).

Biologia     Glossário (ex. epibenthic)

Found in rivers and lakes, apparently in both still and running water; seems to occur in rather acid waters (Ref. 188).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.1   ±0.41 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
