Bornean yellow muntjac

The Bornean yellow muntjac (Muntiacus atherodes) is restricted to the moist forests of Borneo where it lives alongside the common muntjac. It is similar to its much more common cousin and was only recently recognised as a separate species. Apart from the color difference, its antlers, which are just 7 cm (2.8 in) in length, are smaller than those of the common muntjac. It has not been extensively studied and has been described a relict species.
