Amazon River
At approximately 6,400 km (4,000 miles) the Amazon River is the second longest river in the world, just slightly shorter than the Nile although reputable sources disagree as to the exact length of the two rivers.
What is certain is that the Amazon is the largest river in the world by volume, with a total river flow that accounts for approximately one-fifth of the world’s total. The Amazon and its tributaries flow through Peru, Bolivia, Venezuela, Colombia, Ecuador, and Brazil before emptying into the Atlantic Ocean.
The Amazon has over 3,000 recognized species of fish and new species are still being discovered. Along with the Orinoco River, it is one of the main habitats of the Amazon River Dolphin, the largest species of river dolphin, which can grow to lengths of up to 2.6 meters (8.5 feet).
