African Clawed Frog
Xenopus laevis
Quick answer
The African clawed frog is a fully aquatic frog from sub-Saharan Africa, named for the small dark claws on its hind feet. It has a flat body, no tongue or visible eardrum, and uses sensitive fingers and a lateral-line system to find food in murky water. Widely used in scientific research and kept as a pet, it can live 15 years or more.

Where it lives
Ponds, lakes, and slow waters across sub-Saharan Africa; widely introduced elsewhere.
Behavior and adaptations
African clawed frogs spend almost their entire lives underwater, coming to the surface only to breathe. They lack a tongue and teeth, so they shove food into their mouths with their front fingers, and they use a sensitive lateral-line system along their bodies to detect movement in the water. The small black claws on their hind toes give the species its name and help tear apart food.
Diet and feeding
These frogs are scavenging carnivores that eat insects, worms, small fish, crustaceans, and bits of carrion. They detect prey by smell, touch, and water vibrations rather than by sight. Their hearty appetite and tolerance of a wide range of conditions make them easy to keep.
Habitat and range
The African clawed frog is native to ponds, lakes, and slow-moving waters across sub-Saharan Africa. It is extremely hardy and can survive in stagnant or polluted water and even travel short distances over land between pools. Released or escaped frogs have established invasive populations on several continents.
Use in science and conservation
Xenopus laevis is one of the most important laboratory animals, long used in developmental biology, genetics, and, historically, human pregnancy testing. The species is listed as Least Concern and is abundant both in the wild and in captivity. Its main conservation impact is as an invasive species that can spread disease to native amphibians.
Frequently asked questions about the African Clawed Frog
Why is it called the African clawed frog?
It is named for the small, dark, claw-like structures on the toes of its hind feet, which it uses to tear apart food. The 'African' part refers to its native range in sub-Saharan Africa.
What do African clawed frogs eat?
They are carnivores and scavengers that eat insects, worms, small fish, crustaceans, and carrion, pushing food into their mouths with their front fingers since they have no tongue.
How long do African clawed frogs live?
African clawed frogs are long-lived and commonly reach 15 years or more in captivity with good care, which makes them a long-term commitment as pets.
Why are African clawed frogs used in research?
They are hardy, breed readily, and produce large, easy-to-study eggs, making them a key model animal in developmental biology and genetics. They were also once used in human pregnancy tests.
Are African clawed frogs invasive?
Yes, outside their native range. Released and escaped frogs have established wild populations on several continents, where they can outcompete native species and help spread amphibian diseases.
Do African clawed frogs need land in their tank?
No. They are fully aquatic and spend their whole lives in water, surfacing only to breathe, so a pet setup needs deep water rather than a land area.
