Etymology: Rhamphochromis: Greek, rhamphos = bill, peak + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Eponymy: Rodney Carrington Wood (1889–1962) travelled widely, particularly in Africa, farmed at times, worked as a game warden in Nyasaland (now Malawi) which he resigned from (1931), became a schoolteacher in Natal and was also employed by the railways in [...] (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
Diagnosis: large, predatory-looking species; very large mouth and big stout teeth; eye seems very small compared to scaled area of cheek beneath; upper surface of the tip of the premaxilla often extends almost horizontally for a considerable distance when viewed in profile (Ref. 55949).
Found in inshore reef and shelf zones, and offshore in the pelagic zone (Ref. 55949). Few specimens were collected near rocky shores. Occurs in small groups (Ref. 5595). Piscivorous (Ref. 5595, 55949). Female mouthbrooder (Ref. 55949).
