The Common muntjac, also called Indian muntjac (Muntiacus muntjak) is the most numerous muntjac species. It has soft, short, brownish or greyish hair, sometimes with creamy markings. This species is omnivorous, feeding on fruits, shoots, seeds, birds' eggs as well as small animals and even carrion. It gives calls similar to barking, usually on sensing a predator (hence the common name for all muntjacs of barking deer).

The male Indian muntjac has small antlers which attain 15 cm in length and have only 1 branch. They grow anually from a bony stalk on the head. Males are extremely territorial and can be fierce for their size. During the rut they will fight each other using their antlers or their (more dangerous) tusk-like upper canine teeth, and can defend themselves against predators such as dogs.
