Take a trek through the Amazon jungle to see some of the most exotic creatures in the world, including the brown-throated sloth, piranha, howler monkey, toucan and jaguar.
Found in the Amazon rainforest, the brown-throated sloth is the most common of the 4 species of the 3-toed sloth. Its guard hairs are very coarse and stiff, and they have no gall bladder or appendix. Although they can swim and walk along the ground, sloths spend most of their lives high in the tree tops, eating leaves.
