Bonito, Mato Grosso do Sul, Brazil
Shoals of piraputanga that live in the crystal-clear waters of Bonito, in Brazil, are able to use their superior visibility above the surface to find unique feeding opportunities. The fish will often follow troops of brown capuchins along the river as they search for ripe fruit. As the monkeys feed, some fruit invariably falls into the water where the piraputanga are ready waiting. Even after the monkeys have dispersed, the fish, now with the knowledge of where the fruit is, are able to launch themselves out of the water with surprising accuracy to grab it.
