The African Clawed Frog (Xenopus laevis) is a very common pet and lab animal and yet holds many surprises for those willing to look – it has no tongue, produces skin secretions that have yielded valuable medicines, was once used by the millions to detect pregnancy and thrives as an invading species in habitats ranging from Texas cattle ponds to brackish marshes in England… and their tadpoles feed by filtering organic material from the water.
