Korte beschrijving Morfologie | Morfometrie

Dorsale zachte stralen (totaal): 10-12; Anale stekels 0-1; Anale zachte stralen: 19 - 21; Wervels: 38 - 40. Distinguished from Luciocephalus aura in the following characters: absence of numerous iridescent green spots on central stripe when live (vs. presence); presence of black irregular pattern on area below preorbital to central stripe (vs. absence); area just above anal-fin base with 3-4 dark brown blotches, which appear circular when body is viewed ventrally (vs. absence of such markings); yellowish caudal fin with 3-5 broad vertical black bars (vs. brownish caudal fin with 3-7 narrow iridescent vertical gold bars); presence of markings on anal and pelvic (vs. absence); shorter caudal-fin length (total length 120.0-125.6% SL vs. 123.7-127.1); shorter postdorsal length (10.4-12.4% SL vs. 12.0-13.2); greater head length (44.1-48.6% SL vs. 43.3-45.9); smaller caudal peduncle depth (8.9-10.6% SL vs 10.7-11.2); and relatively shorter anal-fin base length (19.3-23.4% SL vs. 23.6-24.5) (Ref. 56386).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Occurs in streams and flooded forest among dense vegetation (Ref. 56749). Found in primary peats swamps. Mouth brooder (Ref. 57235). Highly protrusible jaws. The premaxillae can extend about 1/3 of the head length. Prey is captured by the fish making a rapid lunge and surrounding the prey with the open mouth.

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Kwetsbaarheid (Ref. 59153):  Low to moderate vulnerability (25 of 100) .
