Lemur Is First Known Hibernating Primate, Study Says: "Madagascar, a large, tropical island off the east coast of Africa, isn't the kind of place you'd expect to find a mammal that hibernates. Yet researchers say a small, nocturnal lemur resorts to the same tactic used by bears, squirrels, and dormice to survive cold northern winters -- spending at least seven months of the year hibernating through harsh times brought on by drought.
The German-based team say their study is the only report of prolonged hibernation in a tropical mammal. Furthermore, writing in this week's scientific journal Nature, they claim the study provides the first proof of hibernation in any species of primate."
