Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 47 - 51; Afterflossenweichstrahlen: 31 - 33; Wirbelzahl: 53 - 55. Dorsal surface of the body dark; 8-11 irregular (often anteriorly pointed V-shaped) black blotches or bands on upper half of the body; a white-rimmed black ocellus on caudal peduncle; sparse white spots on body and dorsal and caudal fins. Hyomandibular process with the mid- to lower lateral edge mesially protruded. One to 2 small to medium-sized scales found on the undersurface of each side of the lower jaw. Pelvic fin absent. Cheek scales 9-13 (Ref. 43157).

Obligate air-breathing (Ref. 126274); Generally restricted to relatively narrow regions, characterized by humid rainforest climate (Ref. 43157).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00381 - 0.01816), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).

Preiskategorie (Ref. 80766): Unknown.
