The Pantanal of Brazil, located in southcentral and southwestern Brazil, is an amazing place. 80% of it is underwater in the raining season, making the entire Pantanal (which stretches into Paraguay and Bolivia) the world's largest tropical wetland. Jaguars are best seen on river banks, watching for their favorite foods, cayman or capybara. Giant river otters and giant anteaters often can be seen, as sell as crab-eating foxes, tapirs, and a variety of other mammals and birds.
