Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  mylodon: Named by Regan (1920) presumably in reference to the mill-like molariform pharyngeal dentition of this species (Ref. 52346).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 14 - 15; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 28. Diagnosis: lateral line count of 38-43 scales; 16-17 closely packed gill-rakers along lower limb of first arch; extremely robust lower pharyngeal jaw with mill-like molariform teeth occupying at least 2/3 of dentigerous surface; third pore of mandibular laterosensory canal enlarged compared to size of preceding pores (Ref. 52346).

Biology     Glossary (e.g. epibenthic)

Benthic macrophage (Ref. 52346). Feeds mainly on insects and their larvae, but also (in small quantities) on crustaceans and molluscs (Ref. 52307). Maternal mouthbrooder (Ref. 52307, 52346) that does not pair bond (Ref. 52307). Marked intolerance to oxygen lack (Ref. 246).

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=0.01000 (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).
Trophic level (Ref. 69278):  3.3   ±0.48 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
Price category (Ref. 80766):   Unknown.
