Etymology: Ctenopoma: Greek, kteis, ktenos = comb + Greek, poma, -atos = cover (Ref. 45335).
More on author: Peters.
The species Anabas machadoi Fowler, 1930 is considered valid in Eschmeyer (CofF ver. Mar. 2012: Ref. 89686). It is treated here a synonym of Ctenopoma multispine Peters, 1844 following Skelton et al. (1985: Ref. 79613).

Freshwater; benthopelagic; pH range: 6.0 - 7.5; dH range: 5 - 20. Tropical; 24°C - 27°C (Ref. 2060); 10°S - 28°S
Africa: Lufira River, Lualaba-Upemba, Luapula-Moero in Democratic Republic of the Congo, Upper Zambezi in Zambia and Angola and Cubango-Okovango-Ngami in Angola and Botswana (Ref. 6803). Also known from the Kunene (Ref. 120641), the Kafue and rivers of coastal Mozambique (Ref. 7248), and from the Cuanza (Ref. 7248, 120641) and the Kwango, Kwilu and Kasai systems (middle Congo River basin) in Angola (Ref. 11970).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 6803)
Obligate air-breathing (Ref. 126274); Occurs in vegetated riverine backwaters, floodplain lagoons, swamps and isolated pans. Feeds on any suitably small creature, including insects, shrimps, and small fish. Well camouflaged; hunts by slowly stalking prey. May congregate in groups to breed. The eggs are scattered around and not guarded. Can endure warm stagnant waters and is known to leave the water and move overland to alternative sites in wet weather or at night (Ref. 7248).
