The Cross River Gorilla

The Cross River gorilla (scientific name gorilla gorilla diehli) is a subspecies of the western gorilla that inhabits the lowland montane forests and lowland montane rainforests of Nigeria and Cameroon. It can stand (on two feet) between 4 and 5 1/2 feet tall, and it can weigh up to 440 pounds. It is very similar in appearance to the western lowland gorilla, with the only differences being subtle ones in the dimensions of its skull and teeth. It is wary of humans, most likely because many of them have encroached upon its habitat for the purposes of logging and forest-to-farmland conversion.

This is one of the two reasons why the Cross River gorilla is classified as a Critically Endangered species. Because of this, one of the World Wildlife Fund's (WWF's) efforts to save it consists of working with the Cameroon Ministry of Forest and Wildlife, as well as local communities and logging companies in Cameroon, to foster sustainable management of its habitat. The other reason is that it is illegally hunted, which has a significant negative impact on its extremely small population. Because of this, another one of the WWF's efforts to save it consists of working with officials in both Nigeria and Cameroon to establish a protected area for it that spans the border between these two nations.
