The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is a subspecies of the common chimpanzee which inhabits the rainforests along the border of Nigeria and Cameroon. Male Nigeria-Cameroon chimpanzees can weigh as much as 70 kilos with a body length of up to 1.2 metres and a height of 1.6 metres. Females are significantly smaller.
The Nigeria-Cameroon chimpanzee is recognised as the most threatened and least distributed of all the common chimpanzee subspecies, and without a dramatic change to human behaviour in the area, there is a likelihood of extinction in the coming decades. A June 2008 report said the Edumanom Forest Reserve reserve was the last known site for chimpanzees in the Niger Delta.
