This adorable sleepy Asian Sun Bear cub can't stay awake. Sun bears are nocturnal in which they sleep mostly during the day. The Asian Sun Bear take their name from the bib-shaped golden or white patch on their chest, which legend says represents the rising sun. Also, the Sun Bear is part of a "Species Survival Plan" under the Association of Zoos since late 1994 to help ensure the survival of the species most of which are threatened or endangered in the wild.
