Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); leonensis: Named in reference to the country in which specimens of the species were first identified (Ref. 52346).
Environment: milieu / climate zone / depth range / distribution range
بوم شناسي
; آب شيرين موجوداتی که در محدوده وسیعی از آبهای آزاد از نزدیک بستر و یا روی کف بستر، در قسمت های میان آبی تا سطح آب و در برخی گونه ها با قابلیت پرواز، زندگی و تغذیه می کنند.. Tropical; 24°C - 26°C (Ref. 12468); 10°N - 4°N
Africa: coastal rivers from the Kogon (Guinea) to the Bia (Sierra Leone) (Ref. 53405).
Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 21.9 cm SL جنس نر / بدون خواص جنسي; (Ref. 53405)
خارهاي باله پشتي (کل) : 13 - 15; شعاع نرم باله پشتي (کل) : 13 - 16; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 7; مهره ها: 28. Diagnosis: 2 scale rows between upper lateral line and anterior part of lower lateral line (Ref. 52346, 53405). High lateral line count (38-42); low gill raker count (13-15 along lower limb of first arch); lower pharyngeal jaw with a short, deep keel that is deeply indented along the ventral margin (Ref. 52346).
Appears to be an exclusively Upper Guinean Province species (Ref. 52346). Inhabits large sandbanks and hardly ever penetrates into small streams (Ref. 53407). Benthic macrophage (Ref. 52346). Feeds primarily upon insects and their larvae, but also accepts plants (Ref. 52307). Oviphilous (Ref. 53407), maternal mouthbrooder that does not pair bond (Ref. 52307).
