The Congo River in Africa is 4,700 km long; beginning at the confluence of the Lualaba and Luvua rivers – running southwest to the Atlantic Ocean. It is the ninth longest and also the deepest river in the world.

The Congo River is the source of endemic fish, and the tropical rainforests surrounding it are full of different kinds of animals; such as crocodiles and snakes.

The navigable system of the river serves as the chief passenger and cargo transportation in Africa. However, some areas of the river make navigation hard due to high waterfalls and strong rapids.

The people living around the river also use its resources to fish and to irrigate their crops.
