Western Clawed Frog

Xenopus tropicalis

The western clawed frog (Xenopus tropicalis), also called the tropical clawed frog, is a small fully aquatic frog native to the rainforest belt of West Africa. Like other Xenopus, it has a flattened body, eyes set high on the head, sensitive lateral-line organs, and clawed inner toes on the hind feet used for tearing food. It is best known outside its range as a biomedical research species because it has a compact diploid genome, develops quickly, and is easier to breed in laboratory colonies than many amphibians.

Captive western clawed frogs are kept in aquaria rather than terrariums, with warm clean water, secure lids, and smooth furnishings that do not trap toes or damage skin. They feed on small aquatic invertebrates, worms, prepared frog diets, and other protein foods; fine gravel is often avoided because it can be swallowed. Research colonies pay close attention to water quality, genetic line, health screening, and egg production schedules. Because Xenopus species can carry amphibian pathogens and may become invasive outside their native range, unwanted animals should never be released and local permit rules need checking.
