Post 781: World Rivers Day. There are many great rivers scattered across the globe, but there aren't any rivers quite like the Congo. . While there are longer, more grandiose rivers, there are none that get as deep. Scientists don't actually know how deep it is at its deepest point, but estimates put it at over 750 feet! If the MetLife Tower from Manhattan were to be placed in the river, there would likely still be room for small fishing boats to sail above. . The secret to how a river can be that deep lies in how it pours into the sea. Unlike many rivers, which have a delta (a large fan of small mouths that pour into the ocean), the Congo does not. The narrow channel is less than a mile wide, but with 5 times more water flowing from it than from the Mississippi, it has cut a huge gorge. The slender waterway also has an incredibly fast current, with parts running so fast that many species can't cross. It's the first instance where species are divided not by mountains or oceans - but by currents. Different fish species have evolved on either side of the river, making the mouth of the Congo home to more unique species than almost any other spot on Earth. . .

Graphic shows two fish species looking at each other from across the river. The factoid reads: "The mouth of the Congo holds more unique species than almost any other place in the world." . . #congo #river #riverconservation #animalconservation #worldriversday #riversday #biodiversity #animalfacts #animalart #pixelplanet #pixelplanettoday #pixelart #planetfacts
