With the world´s largest and most visible jaguars, the world´s only habituated family of Giant Otters, as well as Capybaras, Giant Anteaters, Tapirs, 3 monkey species, Hyacinth, Macaws, 400 other bird species, and tens of thousand of caimans, the Transpantaneira is a must for wildlife lovers. Giant Otters are 70-lb, 2-m-long top predators that chase jaguars (seen 4 times). Elsewhere very shy and elusive, the Giant Otters of PWC are completely tame and easy to observe up closed.
