The tropical clawed frog (Xenopus tropicalis) is the next-generation experimental amphibian. It has some notable features that are not possessed by the African clawed frog (X. laevis), which has contributed greatly to the progress of developmental zoology. Xenopus tropicalis is the only amphibian species the whole genome sequence of which has been completed. However, it is still a developing model animal. The foundation that includes methodology and information sharing for research using this animal has not been fully developed because it was introduced to scientific communities only recently. Therefore, this project is aimed at developing a foundation that makes X. tropicalis a polished model animal and increases its use as a resource.
