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).

Biologia     Glossário (p.ex. 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

Índice de diversidade filogenética (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).
Nível Trófico (Ref. 69278):  3.3   ±0.48 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
Categoria de preço (Ref. 80766):   Unknown.
