Xenopus

 

the genus of tailless amphibians of the suborder Aglossa of the family Pipidae. On the head, next to each eye, there are short feelers. The lateral line organs are located on the sides of the body. There are sharp black claws on the three center toes of the hind feet. The genus comprises eight species, which are distributed in tropical Africa. Its members are aquatic. In tadpoles the external gills and larval teeth are absent. A pair of long sensory tentacles are located near the mouth and there are two gill openings. The most common species is Xenopus laevis, which is used as a laboratory animal.
