African Clawed Frog
Aquatic African research frog
The African clawed frog (Xenopus laevis) is a fully aquatic frog native to sub-Saharan Africa. It is easily recognized by the claw-like structures on its hind feet, which it uses to tear apart food. Unlike many frogs, it does not have a tongue and instead uses suction feeding to capture prey. This species became widely used in scientific research and pregnancy testing in the 20th century due to its sensitivity to hormones. It is highly adaptable and has established invasive populations in many parts of the world.
