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).

Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 13-15; Anal spines: 3; Anal soft rays: 7 - 9; Vertebrae: 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. 10616, Ref. 6316). Female carries the eggs (Ref. 1872).
