Gaur or Indian bisons are among the largest living land animals. Only elephants, rhinos, the hippopotamus, and the giraffe consistently grow heavier.The adult gaur has few predators, although the young and unhealthy animals enter the food chain as the prey of crocodiles, leopards, and other large animals, and a tiger can kill an adult. They are in danger of extinction because people are hunting them for their meat, horns and also the domestic cattle are eating up their food.
