非洲爪蟾
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. The word "Xenopus" means "strange foot" and "laevis" means "smooth".
