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).

Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 13 - 14; Raios dorsais moles (total) : 14 - 15; Espinhos anais: 3; Raios anais moles: 7 - 8; Vértebras: 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).

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).

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.
