Descend into a South American rainforest filled with rare and indigenous plants and animals. The bamboo-planked path leads past monkeys, multiple species of toucans, Giant river otters and Orinoco crocodiles. Wrasses, stingray and rare Leafy sea dragons are only a few of the intriguing marine life in the aquarium. The 400,000-gallon Mundo Maya Cenote is filled with sharks and rays.
