Bone Vampire

The Bone Vampire is a species of alien creature that was hunted to near-extinction in Doohan 6.

Overview
It gets its name from its way of feeding itself: by sucking the skeleton out of its victims. It reproduces asexually. By 3011, they were all extinct, with the exception of one egg that was hatched by Fry. When the Planet Express crew  returned it to its homeworld, the populace feared for their livestock, and set to hunt it down. When it is revealed that the people had excessive livestock to slaughter, they spared Mr. Peppy because he can bring back the entire species to help kill the extra livestock.
