They were first isolated from the African clawed frog, Xenopus laevis.
The central pattern generator in Xenopus embryos has been particularly well studied by Roberts and his colleagues.
Similarly, studies on the frog Xenopus laevis show POMC mRNA expression in the same regions.
Similar antero-posterior pelvic movements have been observed in the aquatic frog Xenopus during swimming.
The new species, X. arabiensis, differs from other Xenopus in its long maxilla and maxillary tooth row.
