The lemur, Javan rhino, and Santa Cruz kangaroo rat are all lonesome animals. As endemic species, they live in habitats restricted to a particular area due to climate change, urban development, or other occurrences.

Endemic species are often endangered, and a UT study finds that saving them is more important to biodiversity than previously thought.
