Description
Xenopus laevis varies in size; males (45.6 to 97.5 mm) tend to be be smaller than females (57 to 147 mm). Their heads and bodies are depressed and flattened and they have small round eyes on the top of their heads. The skin is smooth and the hind limbs are long and robust. The three inner toes of the large fully webbed feet have small black claws on them. The body color is usually dark-gray to greenish-brown dorsally, and pale ventrally (Trueb 2003).

This species occurs in savannas of the Republic of South Africa, Kenya, Uganda, Democratic Republic of Congo, and Cameroon. This frog has high tolerance to change in its environment and will survive in nearly any body of water. It can be found in water bodies ranging from ice-covered lakes to desert oases. Unlike most frogs, the African clawed frog can also survive in water with high salinity (Trueb 2003).

Life History, Abundance, Activity, and Special Behaviors
These frogs spend most of their life-cycle in the water, only to leave when there is a drought. When a drought occurs, they will burrow into the drying mud. They can survive up to a year without food. Their diet consists of a wide range of animals including fish, crustaceans, insects, and other frogs. They will also scavenge on dead frogs, fish, birds, and small mammals (Trueb 2003).

Trends and Threats
Not threatened.

Relation to Humans
This is one of the most-studied species of frogs, considered one of the model systems of developmental biology. It is hardy and breeding can be easily induced in the laboratory. Xenopus laevis early development has been studied by developmental biologists for decades and its genome has been fully sequenced. Because it makes a hardy and popular pet, it can also be found in aquariums worldwide. This species has been used as food in African countries (Trueb 2003).
