The Sanje mangabey  is a highly endangered Old World monkey of the white-eyelid mangabey group from the Eastern Arc Mountains in Tanzania.

They are about 50–65 centimetres in length, excluding the tail, and their body colour is greyish. Fruit makes up about 70% of their diet the rest being made of seeds, nuts, insects and other invertebrates.  They live in valley forests and on mountain slopes, but are mostly ground-dwelling, which makes them susceptible to hunting and poaching. Their habitat is being degraded, and the International Union for Conservation of Nature has assessed their conservation status as being “endangered“.

One of the better places to try to see this monkey is within the Udzungwa mountains of Tanzania, there is a national park in this area.

This species was only identified in 1979 by a couple of scientists visiting the area.

It is only found in 2 forests in the country of Tanzania, which are unfortunately widely split, so there is no genetic exchange between the two populations, and lives in mid-altitude forests.

In 2005, the population was estimated at 1300, while unclear, it is likely to have declined in the intervening time.

You will find a list of any articles on this species below (if any – hopefully these will grow overtime). Below the list of articles, we will add any links we make, where you can see this species.

Visiting the area, is one of the easiest ways to show locals the species has more value alive than dead.
