These frogs are exclusively aquatic and have numerous morphological modifications befitting their habitat. For example, the feet are completely webbed and a lateral line system is present. In addition, pipids possess highly modified ears and vocal structures for producing and receiving sound underwater. In fish, the lateral line is a sense organ used to detect movement in the surrounding water. ...
The fossil record for pipids is relatively good with twelve extinct species known. Six of these are placed in the extant genus Xenopus, the remainder in extinct genera. These fossils are known from Africa, South America, and Middle East back to the Lower Cretaceous. FOSSIL is a standard for allowing serial communication for telecommunications programs under DOS.
