Description of life cycle and mating behavior In Polypterus senegalus courtship starts with a series of leaps from the surface by usually only one of the pair at a time, followed by a slow descent through the water. After a while the male stays very close to the female and at times the female will remain motionless in the water and the male will come up to her from behind and nudge her with sidewise movements of his head. The enlarged and swollen anal fin of the male is folded in a cup-like fashion and is used to brush the female (Ref. 42791). No nest is constructed, but the eggs are laid a few at a time throughout the thick vegetation (Ref. 42791). The larvae, which move about with the male parent in a dense school, are provided with accessory gills and appear very salamander-like (Ref. 42791).
