In Africa, these pools are often frequented by hippopotami as well as used as watering holes for a variety of animals and birds including lions and wildebeest. They are often vital to humans, providing water for cattle. A number of species of frog also breed in these pools and marshes, including the North American Bullfrog and the Green Toad. They commonly attract wading birds and waterfowl, including for breeding. Many of these birds are migratory, seeking out specific pools or marshes each year and traveling considerable distances.
These ponds and marshes may also be stocked with smaller freshwater fish, which become food for the otters and wading birds. They are also home to large quantities of insects and invertebrates, and are common breeding grounds for dragonflies and mosquitoes.
