The White-Throated Guenon, also known as the red-bellied monkey and the red-bellied guenon, is a diurnal primate that lives on trees of rainforests or tropical areas of Nigeria and Benin. They are usually frugivores but insects, leaves, and crops are also in their diet. They usually live in small groups of four to five individual monkeys however, there have been groups of 30 discovered, and in cases, some males wander alone. They are arboreal, living in moist tropical forest and the wettest parts of dry tropical forest, however they can also be found in secondary bush and old farmland. Males weigh from 3.5-4.5 kg and females weigh 2-4 kg. Females give birth to one offspring, which is a factor of decreasing population. They were once considered extinct due to constant hunting for the fur of their unique red belly and white front legs, but a small group was subsequently found near the Niger River in 1988. They are still considered an endangered species due to their decreasing population. They are present within Nigerian forest reserves and sacred groves in Benin, but hunting and logging restrictions are difficult to enforce or nonexistent. They are one of the species that live in the Guinean Forests of the West Africa Biodiversity Hotspot.
