Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 14 - 15; Dorsale zachte stralen (totaal): 12-15; Anale zachte stralen: 7; Wervels: 28 - 29. Diagnosis: marked hypertrophy of lateral line canals on flank and caudal fin; inflated preopercular laterosensory canals; distinctive excavation of premaxillary oral valve (Ref. 52346).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Restricted in its distribution to the lake proper and absent from the surrounding swamps and inundated forest (Ref. 52346). Predominantly a lacustrine form (unusual among Tylochromines)(Ref. 52346). Benthic microphage (Ref. 52346). Feeds mainly upon small organic particles, plants and invertebrates; maternal mouthbrooder that does not pair bond (Ref. 52307).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.8   ±0.32 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Prijsklasse (Ref. 80766):   Unknown.
