"The Meeting of Waters is a natural phenomenon that can be seen in some rivers in the Amazon. The most famous place to see it is located in the city of Manaus. It is the point where the dark, muddy waters of the Rio Negro meet the lighter, clearer waters of the Rio Solimões, and the two rivers flow side by side without mixing for several kilometers.
It is a magical place filled with different types of animals, like piranhas, that can be seen swimming through these waters. Piranhas are a type of fish often depicted as ferocious, aggressive creatures. They are sometimes depicted as being attracted to the smell of blood and for attacking humans or animals who are injured or wounded. But it is also said that piranha meat is the ultimate aphrodisiac."
