Watch emperor tamarin go about their business in the patch of rainforest that has been established at London Zoo, while in the meantime interacting with a red titi monkey who seems to disapprove. Rainforest Life, as the exhibit is called, is a magnificent example of how an exhibit can support a thriving community of a variety of species, such as emperor tamarin, red titi monkey, golden-headed lion tamarin, Linne’s two-toed sloth, southern tamandua, and Rodrigues fruit bat.
