Proponents of zoos argue that they offer researchers easy access to the animals and provide money and expertise for preserving their natural habitats, as well as safekeeping for the species. The long bones of the limbs have cancellous bone in place of medullary cavities. [28] Their limbs grew longer and the feet shorter and broader. They were not used as much as horse-drawn chariots by either the Pandavas or Kauravas.
