Brazil Untamed

Venture into the lush confines of the Brazilian Pantanal, host to an assortment of unusual creatures with similarly strange habits. Among these, you'll encounter the piraputanga fish that leaps out of the water to pluck fruit off low-hanging branches and the lowland tapir--the largest land mammal in South America--who can eat up to 100 lbs. of vegetation each day.

At first glance, they look like pigs, but they're actually white-lipped peccaries from the Brazilian wetlands of the Pantanal, 10 times the size of the Everglades. Follow scientists as they track these mysterious mammals in their daily quest for food, while keeping a watchful eye for their main predator: jaguars.

Brazil's rainforests are home to thousands of creatures, but few are as intelligent and graceful as the white-whiskered spider monkey. Watch as these Amazon ambassadors use their long tails like a fifth limb, swinging from branch to branch high above the forest floor. At the Cristalino Private National Heritage Reserve, these endangered primates have found a perfect refuge.
