![]() ![]() The black caiman (Melanosuchus niger) is not only one of the largest predators in the Amazon ecosystem, but also the largest caiman species of the six alive today. The World Wildlife Foundation is working to support the Regional Conservation and Management Plan for River Dolphins in Brazil, Colombia, Ecuador and Peru to increase collaboration between the four countries and conserve the unique freshwater dolphin. Once abundant in the waters of the Amazon and Orinoco rivers of South America, Botos are now considered an endangered species due to recent population declines resulting from human activity.īoto populations are hurt by the damming and contamination of the Amazon River and are killed by fishermen for use as bait to catch catfish. While ocean dwelling dolphins lose the hairs on their rostrum shortly after birth, Botos keep their hair into adulthood. The striking freshwater mammal is also the dolphin with the most hair, with bristles on its snout acting as a sensory device in feeling for food on the muddy river bottoms. Unlike their marine cousins, Botos live exclusively in freshwater habitats.Īlthough Botos appear light grey in color, they flush pastel pink when excited - just like a human blushing! This colour-changing characteristic historically spared them from human persecution because of the belief that it was a special power. Known for its innumerable wildlife species, the Amazon River is the habitat for the largest species of river dolphin, which can attain a length of up to 2.6 m (9 ft).įamed for its unique pink colouration, the boto (Inia geoffrensis), also known as the Amazon River dolphin or pink river dolphin, is one of only four "true" river dolphin species. Its flow is also 60 times greater than that of the Nile. Together, this freshwater flow accounts for nearly 20% of all river water that enters the sea. The outflow of water produced each day generates enough power to keep New York City supplied with electricity for nearly a decade. ![]() While not in flood, the river’s main stretches can reach widths of up to 11 km (7 miles), also making it the widest river in the world. The lower 1,450 km (900 miles) average 17 m (55 ft) in depth, but the river has a maximum depth of 124 m (407 ft). It discharges an average of 200,000 cubic metres per second (7,100,000 cubic feet per second) into the Atlantic Ocean, increasing to more than 340,000 cubic metres per second (12,000,000 cubic feet per second) in full flood. The Amazon River has the largest volume of fresh water of any river in the world and is the greatest river (by flow rate). ![]() ![]() In celebration of Earth Day, we’ve rounded up some of the most interesting records that make the mighty Amazon one of the wonders of the world. It nurtures the largest rainforest in the world and provides life for a vast array of flora and fauna.ĭespite centuries of exploration, it's still a magical place that houses many secrets. #MarcaPerú #AmazonRiver /V6WsEZCW42- peru November 11, 2021 We celebrate the tenth anniversary of the declaration that recognizes the majestic Amazon River as a natural wonder. The Amazon River, NATURAL WONDER OF THE WORLD! □ □□ The Amazon River's role as a global freshwater powerhouse, its geologic past, special wildlife and impact on ecosystems in the region make this river one of the most fascinating places on Earth. Its massive amount of water feeds the adjoining Amazon Rainforest, makes it impossible to build bridges over and raises the height of the ocean in the Caribbean Sea. The Amazon River is one of the most complex and vital water systems in the world. ![]()
