Capybaras primarily live in South America, inhabiting dense forests, savannas, and wetlands near bodies of water such as lakes, rivers, swamps, ponds, and marshes. They are semiaquatic mammals found throughout most South American countries except Chile and prefer areas where water is easily accessible. Their habitat includes tropical rainforests, flooded grasslands, and savannas, and they thrive in environments like the Amazon River region and Pantanal wetlands. Additionally, there are sightings of capybaras in other places like Florida in the United States, mainly from escaped or released pets, but their natural and main habitat is in South America.
