Brazil Untamed

Venture into the lush confines of the Brazilian Pantanal, host to an assortment of unusual creatures with similarly strange habits.

At first glance, they look like pigs, but theyre 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.
