The Fea’s muntjac or Tenasserim muntjac is a rare species of muntjac native to southern Myanmar and Thailand. It is a similar size to the common muntjac (adult weight is 18 – 21 kg (40 – 46 lb)). It is diurnal and solitary, inhabiting upland evergreen, mixed or shrub forest (at an altitude of 2500 m (8200′)) with a diet of grasses, low-growing leaves, and tender shoots. The young are usually born in dense vegetation, remaining hidden until able to travel with the mother.

It is named after zoologist Leonardo Fea. Its other name comes from the Tenasserim Hills, between Burma and Thailand. This muntjac is considered as data deficient, so we do not know how this species is doing well in the wild – though it should be recognized that it is rare. Part of the reason for this is that its home territory is mountainous and therefore hard to enter, and at the same time, it is small and very shy, which means that when possible it keeps out of site. It inhabits upland evergreen, mixed or shrub forest.

The area where they live have a wide range of predators (this includes tigers, leopards, jackals, dholes, crocodiles, foxes, and even pythons) which are good at taking species like this. As such, hiding is often a far better way of escaping than to flee.

Its conservation status is considered endangered
