Diagnosis: Protopterus annectens annectens has an elongate body and paired fins are long and filamentous (Ref. 81261). The trunk, with 34-37 ribs, is a bit longer and the tail a bit shorter compared to Protopterus annectens brieni (Ref. 40587).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Obligate air-breathing (Ref. 126274); Obligate air-breathing (Ref. 126274). Found in marginal swamps and backwaters of rivers and lakes (Ref. 30488). Carnivorous, food includes molluscs (Ref. 30488), but also frogs, fish and seed (Ref. 13851). In Kenya it feeds mostly on plant material, like roots (Ref. 30558). Strongly associated with life of aquatic plants in terms of breeding and feeding ecologies; nests are made in weedy areas (Ref. 30558). Normally lives on flood plains and secretes, when these dry up during the dry season, a thin slime around itself which dries into a fragile cocoon; normally hibernates from the end of one wet season to the start of the next, buut can live in its cocoon for over a year (Ref. 3023, 30558). For hibernating the fish literally chews its way into the substrate ejecting mud out of its gill openings, reaching a depth of 3-25 cm below the surface depending on the length of the fish; the lungfish wriggles around, thereby hollowing out a bulb-shaped chamber and coming to rest with its nose pointing upward; they breathe air at the mouth of the chamber's tube and then sink back into the expanded part of the chamber (Ref. 36739). As the water disappears the respiratory trips cease; air reaches the fish via the tube to the surface (Ref. 36739). Under aquatic conditions this lungfish can survive more than three and half years of starvation, showing the same behavior - no motion and same body posture - as an aestivating specimen (Ref. 51339).

Life cycle and mating behavior Maturities | ການສືບພັນ | Spawnings | Egg(s) | Fecundities | ຕົວອ່ອນ

Lungfish spawn in the swamps during the wet season, building a nest in which the eggs, white in colour and about 4 mm diameter, are laid; young are cared for by the males (Ref. 13851). Larvae hatch in eight days, and leave the nest in twenty days (Ref. 41544). Males of Protopterus annectens brieni excavate an U-shaped burrow to a depth of nearly 60 cm for spawning purposes; nest is usually placed amongst roots of aquatic vegetation where the male will attend to several females during the breeding season; males aerate the eggs with body and fin movements and provide protection to the young for some time after incubation (Ref. 13337).
