The mammals are the class of vertebrate animals characterized by the presence of mammary glands, the presence of hair or fur; specialized teeth; the presence of a neocortex region in the brain; and endothermic or 'warm-blooded' bodies. The brain regulates endothermic and circulatory system, including a four-chambered heart. In India there are 410 species, 186 genera, 45 families and 13 orders of which nearly 89 species are listed as threatened in the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of Threatened Animals (IUCN 2006).

The chital (Axis axis), also known as spotted deer commonly inhabits wooded regions of India, Sri Lanka, Nepal, Bangladesh, Bhutan, and in small numbers in Pakistan. It is the most common deer species in Indian forests. The chital's coat is pinkish fawn, marked with white spots, and its underparts are also white. Its antlers, which it sheds annually, are usually three-pronged and curve in a lyre shape and may extend to 75 cm (2.5 ft). Their lifespans are around 8-14 years.
