The Congo River is the world's deepest river, with measured depths of around 220 meters (720 ft). It's located in Africa.
The River begins in the highlands of Zambia and ends in the Atlantic Ocean in the Democratic Republic of the Congo.
It's the second-longest river in Africa, after the Nile.
Most of the world's great rivers end in a maze-like delta of tributaries, but not the Congo. Its water hits the Atlantic in a single narrow channel, which scientists believe is more than 750 feet deep at some points.
The Basin is an extraordinarily diverse ecosystem. There are over 10,000 species of tropical plants – 30% of which cannot be found anywhere else on earth. Around 400 different mammals and 1,000 species of bird call the basin their home.
