O 'balé aquático' das curimbas: a rota de sobrevivência de cardumes gigantes pelos rios do Pantanal

A massive school of curimbas fish was observed migrating upstream in the Rio Miranda in Brazil's Pantanal region, a yearly reproductive behavior called piracema. The migration is critical for the fish's reproductive cycle, driven by environmental factors such as rainfall and water quality, underscoring the ecological importance of river preservation.
