Rabbit is a fast runner. The hind limbs and hind feet help it in leaping and fast running. The bones of hindfoot are made up of tarsals, metatarsals and phalanges. Ankle or tarsus contains 6 tarsal bones arranged in two rows. Tibiale and intermedium of proximal row are fused to form astragalus lying on the preaxial side. Other bone of proximal row, called calcaneum, is the largest tarsal bone, produced into a spur or process behind its articulation with tibio-fibula. It occupies the post-axial side. A single centrale lies just in front of astragalus. Distal row includes three bones — mesocuneiform, ectocuneiform and cuboid. There are 4 long slender, metatarsal bones supporting the sole, the first being absent. First toe or hallux is also absent so that there are only four toes, each composed of three phalanges, the terminal one of which bears a claw.
