Raninidae is a family of unusual crabs sometimes known as frog crabs on account of their frog-like appearance. They are taken by most scientists to be quite primitive among the true crabs. They closely resemble the (unrelated) mole crabs due to parallel evolution or convergent evolution. In both groups the claws are modified into tools for digging and the body is a rounded shape that is easy to bury in sand.
