Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  elongatus: Named in reference to the relatively elongate, gracile body form of the adult specimens of the species (Ref. 52346).

Environment / Climate / Range Ecology

Freshwater; benthopelagic.   Tropical, preferred ?

Maturity: Lm ?  range ? - ? cm
Max length : 15.3 cm SL male/unsexed; (Ref. 5714)

Short description Morphology | Morphometrics

Dorsal spines (total): 14; Dorsal soft rays (total): 15; Anal soft rays: 7; Vertebrae: 28. Diagnosis: 15-16 gill-rakers along lower limb of first arch; 36-38 lateral line scales (count started on upper line and continued on lower line, including the intermediate scales); an extremely robust lower pharyngeal jaw with mill-like molariform teeth occupying 2/3 of the dentigerous surface (Ref. 52346).

Biology     Glossary (e.g. epibenthic)

Probably a benthic macrophage (Ref. 52346). Seems to feed mainly on insects and insect larvae (Ref. 52307).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  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), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.28 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
