Which frogs are toothless, tongueless and completely aquatic?
The African clawed frog "Xenopus laevis" is a species of the family ''Pipidae''. Its name is derived from the three short claws on each hind foot.The ''Xenopus'' means 'strange foot' and "laevis" means 'smooth'.The species "X.laevis" is found throughout of Sub-Saharan Africa (Nigeria and Sudan to South Africa), and in isolated, South Africa, and Europe.
The African clawed frogs are tongueless, toothless and completely aquatic. They use their hands to shove food in their mouths and down their throats and a hyobranchial pump to draw or suck things in their mouth. They have powerful legs for swimming and lunging after. They use their sensitive finger, sense of smell, and lateral line system to find food.
They are scavengers and will eat almost anything living, dying or dead and any type of organic waste. These frogs are plentiful in ponds and rivers. ''Wild type'' African clawed frogs and ''Albino" varieties are sold as pets. The A.clawed frogs are the only amphibians to have actual claws used to climb. They have been known to survive 15 or more years in the wild and 25-30 years in captivity. The A.clawed frogs have been extensively used by research. They prefer to spend all of their time in stagnant water where they live, feed and reproduce.
