These frogs are the only species of amphibian known to actually have claws. They will use them to tear up flesh for food. The African clawed frog is fairly popular as a pet and is easy to care for. They are similar to the dwarf frogs that are very common in most stores that sell tropical fish. The Xenopus laevis (African Clawed) has only webbed back feet, while the dwarf’s have webbing on all four. These frogs are found in the South-Eastern portion of Africa. They are common in ponds and rivers of Sub-Saharan areas. Males are usually 20% smaller than females. This species does not have a tongue or a vocal sac as most frogs do. They do however make calls to signal breeding. The males will contract muscles which make noises similar to that of a cricket while underwater.
