Description of life cycle and mating behavior | 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). |
