The Guardian takes a look at some of the 441 new species that have been discovered in the Amazon rainforest in just the past four years in this article & photo gallery. Among the newly discovered species: the critically endangered Caqueta titi monkey that purrs like a cat, and a passion flower with curious spaghetti-like tendrils. Many of the newly discovered species are threatened by loss of habitat, climate change, and other environmental issues.
