Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); polylepis: Named by Boulenger (1900) presumably in reference to the species' numerous small scales and the resultant high lateral line formula (Ref. 52346). Polys= Greek for many, lepis= Latin for scale (Ref. 52307).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 14 - 16; членистые (мягкие) лучи спинного плавника (общее число) : 13 - 15; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 7 - 9; позвонки: 30. Diagnosis: high lateral line count (54-59 scales)(Ref. 52346). Scales small (Ref. 53244).
Swamp-dweller (Ref. 6770). Juveniles are coastal and gregarious while adults wander over the sandy bottoms by themselves (Ref. 6770), in shallow inshore areas of the lake, in lagoons and river mouths (Ref. 4967). Feeds mainly on crustaceans and insects, along with some plants (Ref. 52307), but also a mollusc eater (Ref. 6316, 10616). Maternal mouthbrooder (Ref. 1872, 52307) that does not pair bond (Ref. 52307). Females have been observed with about 100 eggs of a diameter of 6 mm (Ref. 52307).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00780 - 0.04874), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.44 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (15 of 100).
Nutrients (Ref.
124155): Calcium = 135 [67, 236] mg/100g; Iron = 1.63 [0.87, 3.40] mg/100g; Protein = 18.6 [17.1, 20.2] %; Omega3 = 0.354 [0.132, 1.005] g/100g; Selenium = 83.5 [33.6, 188.4] μg/100g; VitaminA = 14.6 [3.8, 46.5] μg/100g; Zinc = 1.43 [0.93, 2.20] mg/100g (wet weight);
