The world's largest wetland floods an area many times the size of the Everglades
Sprawling across Brazil, Bolivia and Paraguay, the Pantanal is the largest tropical wetland on Earth, roughly ten times the size of Florida's Everglades. Seasonal floods submerge most of the region for months at a time, supporting one of the densest concentrations of jaguars, caimans and macaws found anywhere in South America.
