The Amazon’s big fish poop seeds far from where they eat fruit, helping to maintain the genetic diversity of the tropical forest, according to new research that shines light on a little-studied mechanism of seed dispersal.

The seed excretions occur during the six- to eight-month-long flood season, when the characid fish Colossoma macropomum swim from lakes and rivers into vast floodplains where they gobble up fruit dropped by trees and shrubs.
