The African clawed frog (Xenopus laevis, also known as the 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 three short claws on each hind foot, which it uses to tear apart its food. Minimum Tank Size: 10 gallons The most striking findings in the study, published on January 25, 2021 in Neuron, were derived from experiments using embryos of the western clawed frog (Xenopus tropicalis), a species prized by biologists for the unique insights it offers into development. The genome of the African clawed frog Xenopus laevis (top) is roughly double that of the related western clawed frog X. tropicalis (bottom). During the 1940s, female African clawed frogs were used as indicators of human pregnancy. Males weigh 2 ounces (60 grams), and are about 2 to 2.5 inches (5 to 6 centimeters) long.
