Rising in the Peruvian Andes, its main trunk flows eastwards across Brazil. On its way the system drains 1 3 of South America. Eventually, over 4, 000 miles from its source, it empties into the Atlantic Ocean. The Amazon transports a billion tonnes of sediment a year, sediment clearly visible at the mixing of the waters where one massive tributary, the Rio Negro, flows into the main river. Its waters are wonderfully rich. To date over 3, 000 species of their fish have been described more than in the whole of the Atlantic Ocean. The Amazon is so large and rich in fish that it can support fresh water dolphins. These botos are huge two and a half metres long. |
