The greatest of all rivers is the Amazon. It goes across 6000 kilometers of South
America touching 9 countries. In the deep rivers and lakes of the Amazon,
pink river dolphins
(river dolphins), called bouto, boto or bufeos by local fishermen, swim in small
groups eating a variety of fish including piranha and crabs. These river dolphins
are known for their pink coloring. Sadly, all the river dolphins may soon be
extinct due to pollution and the pressure of human hunting if great changes do
not occur swiftly. In the Amazon, it is not uncommon for problems to occur with
fishing nets where the dolphins end up drowning when caught in the nets. There
are many legends and beliefs surrounding this mammal which may cause the superstitious
to eye the dolphins with a less than beneficial eye. Also, pink dolphins are
hunted for their eyes, teeth and genitals because of supposed aphrodisiac powers.
In addition, boats carrying oil and toxins occasionally wreck and spill pollutants
which cause a threat for hundreds of miles of waterway.
