Scientists have made a marvelous discovery of a lizard in Vietnam cuisine, which does not reproduce by mating but through the process of cloning.
The lizard is called Leiolepis ngovantrii, according to National Geographic News.
"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," he added.
The lizard is an all-female species. Only one percent of lizards are able to reproduce on their own by cloning (parthenogenesis).
Grismer's colleague Ngo Van Tri of the Vietnam Academy of Science and Technology was the first to notice a restaurant in Ba Ria-Vung Tau Province selling oddly looking lizards, and sent pictures to Grismer and his son Jesse, a herpetology doctoral student at the University of Kansas.
The father-duo researchers suspected that they had found an all-female lizard species.
Grismer and his son flew to Ho Chi Minh City, spoke to the restaurant owner to reserve the lizards and drove eight hours on a motorcycle.
