The Aka or Bayaka are a nomadic Mbenga pygmy people who live by hunting. Although the Aka people call themselves BiAka, they are also known as Babenzele in Western Central African Republic and Northwest Congo (RPC).
They live in a variety of terrains in southwestern Central African Republic and northern Congo (Brazzaville region), in 11 different ecological zones of the Western Congo Basin. They are a related, but distinct, people from the Baka people of Cameroon, Gabon, northern Congo, and southwestern Central African Republic.(Wiki)

Ijaw (also known by the subgroups "Ijo" or "Izon") are a collection of peoples indigenous mostly to the forest regions of the Bayelsa, Delta, and Rivers States within the Niger Delta in Nigeria. Some are resident in Akwa-Ibom, Edo, and Ondo states also in Nigeria. Many are found as migrant fishermen in camps as far west as Sierra Leone and as far east as Gabon along the Western Africa coastline.
The Ijo people number about an estimated 3.4 million. They have long lived in locations near many sea trade routes, and they were well connected to other areas by trade as early as the 15th century.[2] The current President of Nigeria, Goodluck Jonathan, is an Ijaw.
