Xenopus laevis frog, coloured X-ray. This frog is widely used in biology as a model organism, as its egg cells are large and easy to manipulate in the laboratory. It is also popular in the pet trade, where it is usually known by its common name, the African clawed frog. It is almost exclusively aquatic, using its powerful back legs for swimming and burying itself in the mud, rather than for jumping like terrestrial frogs.
