The fauna of the region includes an incredible variety of mammals, such as the giant anteater, jaguar, Brazilian tapir, giant armadillo, pale-throated three-toed sloth, and capybara. A large number of primate species live there as well, such as the howler monkeys, titi monkeys, the white-faced saki, and others.

Yes, the area surrounding Angel Falls (Salto Ángel) in Venezuela is one of the most biodiverse regions on Earth, though the vertical face of the falls itself is a harsh environment. The falls are located within Canaima National Park, characterized by "Tepuis" (flat-top mountains). The rainforest at the base is home to iconic South American wildlife, including jaguars, pumas, giant anteaters, and various species of monkeys like the Red Howler. The avian life is particularly spectacular, with Harpy Eagles and colorful Macaws frequently seen in the canopy. On the summit of Auyán-tepui, where the water begins its fall, there are "islands of evolution" containing endemic species of frogs and lizards that exist nowhere else in the world. While you won't find fish living in the actual 3,212-foot vertical drop of the water, the rivers at the bottom are teeming with diverse aquatic life. The constant mist and humidity created by the falls support a lush micro-ecosystem of bromeliads and orchids, which in turn host a vast array of unique insects and hummingbirds, creating a complex and vibrant food web in the heart of the Guiana Highlands.
