There are at least 11 or more primate species in Tropic World, plus an assortment of other animals from 3 different continents. In the entire building there are orangutans, gorillas, white-cheeked gibbons, spider monkeys, capuchins, cotton-top tamarins, red-capped mangabeys, syke's guenons, colobus monkeys, sooty mangabeys, mandrills, pygmy hippos, brazilian tapirs, giant anteaters, small-clawed otters...and possibly another 1 or 2 species of primate. In the photo above I believe that it is showing the African section of the habitat.
