From the Moody Gardens website:
Experience a breathtaking tribute to the world’s vanishing rainforests and its inhabitants.
As you enter through a tree-top canopy entrance, you'll visit the rainforests of Asia, Africa and the Americas in a rare, up-close and interactive adventure with over 1,700 exotic plants and endangered animals that range from Giant Amazon River Otters to an ocelot, Kmodo dragons and other reptiles. Saki monkeys, Cotton-top tamarins, and sloths roam freely while an array of birds fly between the trees as you walk the trails through the spacious enclosure!
