From the Moody Gardens website:
Experience a breathtaking tribute to the world’s vanishing rainforests and its inhabitants.
As you enter through a treetop canopy entrance, you'll visit the rainforests of Asia, Africa and the Americas in a rare, upclose 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, Cottontop tamarins, and sloths roam freely while an array of birds fly between the trees as you walk the trails through the spacious enclosure!
