Protopteridae (African lungfishes)
Etymology: Protopterus: Greek, pro = first, in front of + Greek, pteron = wing, fin (Ref. 45335); dolloi: Named after Louis Dollo, for his work on the phylogeny of the lungfishes (Ref. 41613).

Diagnosis: Body cylindrical and more elongate than in other Protopterus species (Ref. 81627). Pectoral and pelvic fins filamentous (Ref. 40587). About 85-95 scales on the longitudinal line between operculum and anus (Ref. 104724).
Body shape (shape guide): elongated; Cross section: circular.
Obligate air-breathing (Ref. 126274); Protopterus dolloi is not aestivating in cocoons during the dry-season, because the habitat in which it lives is never completely dry (Ref. 81627); although it never lost the capability to aestivate (Ref. 40587). Therefore, the tunnel which it digs is not for hibernation but functions as a protected chamber during reproduction, which takes place in the dry season (Ref. 81627). The male guards the eggs and larvae in the nest, which is built in the mud of the swamps, while the females can be found in the open water of the rivers (Ref. 41587, 81627). The food of Protopterus dolloi are fishes and insects, but during the time of reproduction its food is more vegetarian (Ref. 40587, 46852).
