Sarcopterygii (lobe-finned fishes) > Lepidosireniformes
(South American and African lungfishes) > Protopteridae
Etymology: Protopterus: Greek, pro = first, in front of + Greek, pteron = wing, fin (Ref. 45335). More on author: Peters.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 5°S - 28°S
Africa: East African coastal regions from Somalia and Kenya, and delta of Zambezi River (Ref. 3498). Reported from Lake Rukwa basin and flood plains of Ruaha and lower Rufiji (Ref. 4967, 41366, 89002), but this species was never positively identified from Tanzania (Ref. 27292). The presence of this species in southern Africa also requires confirmation (Ref. 7248, 52193).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 44.3 cm TL male/unsexed; (Ref. 3498)
Diagnosis: distance snout to origin of dorsal fin 1.4-1.7 times head length, or 45-56% distance snout to vent (Ref. 7248, 52193).
Found in swamps and flood plains (Ref. 43033). Lungfishes survive for months under the dried mud of floodplains (Ref. 4967).
