An awesome view on a rainy day from Kinshasa’s side of the Congo River where you can see the Brazzavile-Congo in the distance.

Ken Jennings for Conde Nast Traveler writes, “Biologists love the lower Congo, because it’s the first place they’ve ever found animal populations divided not by mountains or oceans, but by river currents. The river is less than a mile wide here, but entirely new species of fish are evolving on the two banks, because impenetrable currents divide their habitats. This seemingly bottomless canyon is now known to hold more unique species than almost any other spot on Earth.”
