'Vampire' Squirrel Has World's Poofiest Tail, Reputed Taste For Blood

Researchers recently determined that tufted ground squirrel, Rheithrosciurus macrotis, a rarely seen inhabitant of the forests of Borneo, has the bushiest tail, relative to its body, of any mammal on Earth. It is also, according to Bornean lore, a bloodthirsty killer.

Local legends suggest that Rheithrosciurus, which is thought to mostly eat giant acorns, can be savage. Hunters say that the squirrels will perch on low branches, jump onto a deer, gash its jugular vein, and disembowel the carcass.

"It sounds pretty fantastical," says Roland Kays, a zoologist at the North Carolina Museum of Natural Sciences in Raleigh. "Even more than its fluffy tail."

I don't know. That tail is pretty fantastic. Of course, R. macrotis has got nothing on the overall fluff of this angora rabbit.
