The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
Xenopus is also a unique system for analyses of genome evolution and whole genome duplication in vertebrates, [12] as different Xenopus species form a ploidy series formed by interspecific hybridization. [13] In 1931, Lancelot Hogben noted that Xenopus laevis females ovulated when injected with the urine of pregnant women. [14]
Müller's platanna (Xenopus muelleri), also known as Müller's clawed frog, [3] [4] is a species of frog in the family Pipidae found in Angola, Benin, Botswana, Burkina Faso, Cameroon, the Central African Republic, Chad, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Eswatini, Ghana, Kenya, Malawi, Mozambique, Namibia, Nigeria, South Africa, Sudan, Tanzania, Togo ...
Xenbase is a Model Organism Database (MOD), providing informatics resources, as well as genomic and biological data on Xenopus frogs. [1] Xenbase has been available since 1999, and covers both X. laevis and X. tropicalis Xenopus varieties. [2]
Scopus xenopus is an extinct species of bird related to the hamerkop that lived during the Pliocene of South Africa. It was first described by Storrs L. Olson in 1984. Compared to S. umbretta , the modern hamerkop, S. xenopus was larger and had a foot structure more adapted to swimming.
It is the only species in the genus Xenopus to have a diploid genome. [3] [4] Its genome has been sequenced, [5] [6] making it a significant model organism for genetics that complements the related species Xenopus laevis (the African clawed frog), [7] a widely used vertebrate model for developmental biology.

The Bouchia clawed frog (Xenopus pygmaeus) is a species of frog in the family Pipidae found in the Central African Republic, the Democratic Republic of the Congo, Uganda, and possibly the Republic of the Congo.
