Here are some of the mind-blowing facts about The Great Amazon River.
- The total length of the river is at least 6,992 km (4,345 miles), which makes it slightly longer than the Nile River (6853 km) but still the equivalent of the distance from Rome to Bengaluru.
- At an average discharge of about 209,000 cubic meters per second (7,400,000 cu ft. /s); approximately 6,591 cubic kilometers per annum (1,581 cu mi/a), Amazon River is the largest river by discharge of water in the world. Its discharge is greater than the next seven largest independent rivers combined.
- Amazon River represents 20% of the global riverine discharge to the ocean.
- During the wet season, the Amazon River can reach over 250 kilometers (155 miles) in width.
- Amazon’s depth in its lowermost section averages 20 to 50 meters (66 to 164 ft.), and in some places as much as 100 meters (330 ft.).
- The Amazon basin is the largest drainage basin in the world, with an area of approximately 7,050,000 square kilometers (2,720,000 sq. mi). The portion of the river’s drainage basin in Brazil alone is larger than any other river’s basin.
- The Amazon enters Brazil with only one-fifth of the flow it finally discharges into the Atlantic Ocean, yet already has a greater flow at this point than the discharge of any other river.
- Amazon releases up to 300,000 cubic meters per second (11,000,000 cu ft. /s) in the rainy season, with an average of 209,000 cubic meters per second (7,400,000 cu ft. /s) to the Atlantic Ocean.
- The Amazon is responsible for about 20% of the Earth’s fresh water entering the ocean.
- The fresh water, being lighter, flows on top of the seawater, diluting the salinity and altering the color of the ocean surface over an area up to 2,500,000 sq. km (970,000 sq. mi) in extent. For centuries ships have reported fresh water near the Amazon’s mouth yet well out of sight of land in what otherwise seemed to be the open ocean.
- There are no bridges that cross the Amazon mostly because of its huge width.
- The longest snake in the world, Anaconda lurks in the shallow waters of the Amazon Basin.
- To date, at least 40,000 plant species, 427 mammals (e.g. jaguar, anteater and giant otter), 1,300 birds (e.g. harpy eagle, toucan and hoatzin), 378 reptiles (e.g. boa), more than 400 amphibians (e.g. dart poison frog) and around 3,000 freshwater fishes including the piranha have been found in the Amazon.
- More than one-third of all known species in the world live in the Amazon rain-forest. It is the richest tropical forest in the world in terms of biodiversity. Scientists believe that there are many species which are yet to be discovered.
- It has over a thousand tributaries and 17 of them are over 1,500 kilometers (932 miles) long.
- Martin Strel swam the entire length of the Amazon river in 2007. He took roughly 660 hours of swimming in 66 days to complete this journey.
- Because of its vastness, it is sometimes called as The River Sea.
