African Clawed Frog
This is a unique family of frogs that lack a tongue and a visible ear. The males also lack vocal cords. Instead of moveable eyelids, a horny, transparent covering protects their eyes. The body is flattened and the head is wedge-shaped and smaller than the body. The African clawed frog’s front limbs are small with unwebbed fingers that are used to push food into the mouth. Its hind legs are large and webbed and the three inside toes on either foot have claws, this is where they get their common name. However, while they may look like claws, they are not true claws but cornified tips. This frog has smooth slippery skin, which is multicolored on its back with blotches of olive gray or brown. The underside is creamy white with a yellow tinge. African clawed frogs have the ability to change their appearance to match their background. They can become dark, light, or mottled. They also have a lateral line system that is very sensitive to movement of water.
