New Self-Cloning Lizard Found in Vietnam Restaurant

What's more, the newfound Leiolepis ngovantrii is no run-of-the-mill reptile—the all-female species reproduces via cloning, without the need for male lizards.

Single-gender lizards aren't that much of an oddity: About one percent of lizards can reproduce by parthenogenesis, meaning the females spontaneously ovulate and clone themselves to produce offspring with the same genetic blueprint.

"The Vietnamese have been eating these for time on end," said herpetologist L. Lee Grismer of La Sierra University in Riverside, California, who helped identify the animal.

"In this part of the Mekong Delta [in southeastern Vietnam], restaurants have been serving this undescribed species, and we just stumbled across it."
