Short description Morfología | Morfometría

Espinas dorsales (total): 2; Radios blandos dorsales (total): 6; Radios blandos anales: 11 - 14; Vértebra: 46 - 50. Distinguished by having 2-3 rows of heavy, firmly attached conical teeth on premaxillae and dentaries; lacrimal (= infraorbital 1+2) shaped as an obtuse-angled triangle with nearly straight sides; relatively long, nearly straight-margined adipose fin (its length 2.0-2.5 in SL); short dorsal fin spine, low dorsal fin (spine length 5.6-8.6 in SL); relatively small head (head length 4.0-5.2 times in SL); small eye (horizontal diameter 3.4-5.5 times in snout length, 7.4-12.0 times in head length); neural spines of vertebrae 13 or 14 - 23 or 24 oriented 90°to horizontal axis of centra; supraoccipital process with a narrow median keel above somewhat concave sides, markedly angular in cross-section, slender and tapering to its peg-and-socket joint with supraneural (basal width of supraoccipital process about 2 times in length); anterior anal-fin rays broad, forming a paddle-like blade; posterior nostril ovoid, its long axis oriented transversely (Ref. 57763).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00420 - 0.01982), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.8   ±0.7 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (23 of 100) .
