Meet a new prince of the underworld—the Beelzebub bat.
Named for its diabolic coloration, the recently discovered bat has a black head and dark back fur, both of which contrast sharply with the flyer's whitish belly, scientists reported in a September study.
Despite the fiendish name, Beelzebub bats are typically shy creatures, doing their best to avoid humans in their remote rain forest habitat in Vietnam, scientists say.
If captured, however, the bats can turn fierce, said study co-author Neil Furey, a biologist with the conservation group Fauna & Flora International.
"Once in the hand, they will do their best to escape," he said.
"In essence, they exhibit a 'flight' first and 'fight' second response—the latter only when they have no other option."
