The large river known for its delta in Nigeria is the Niger River. Spanning about 4,180 kilometers, it is one of Africa's major waterways. The river flows through several countries before reaching the coast at the Niger Delta, a region rich in biodiversity and economic resources, particularly petroleum. The delta area supports numerous communities and a wide variety of wildlife, including many fish species and bird populations. The Niger River is essential for agriculture, transportation, and cultural life in the surrounding regions.
