Scientists have confirmed the second case of a "virgin birth" in a shark.

In a study reported Friday in the Journal of Fish Biology, scientists said DNA testing proved that a pup carried by a female blacktip shark in a Virginia aquarium contained no genetic material from a male.

The first documented case of asexual reproduction, or parthenogenesis, among sharks involved a pup born to a hammerhead at an Omaha, Neb., zoo.
