The Senegal Running Frog lives across a wide variety of habitats such as grasslands, shrublands, savannas, and wetlands in sub-Saharan Africa. Due to its large range, the frog could actually be multiple different cryptic species. More research and testing is needed to confirm this. The genus Kassina is known as the Running Frogs due to their weird walking they do instead of hopping like a regular frog. I don’t know why they call them running frogs instead of walking frogs though.

During mating season (spring to late summer), the male frogs call out from the edges of temporary or permanent water bodies to attract females. Once the female arrives, the male grasps her from behind in amplexus. Then, the female lays her eggs and the male fertilizes them. The female lays between 100 to 500 eggs. The parents provide no parental care for their offspring. The eggs hatch in 5 or 6 days and then the tadpoles take between 50 and 90 days to complete their metamorphosis.

The International Union for the Conservation of Nature (IUCN) Red List assess the Senegal Running Frog as Least Concern for Extinction. They have a huge range and are presumed numerous throughout it.
