Watch: Endangered lion cubs born in Rome zoo

Two rare lion cubs were on show for visitors at the Rome Zoo on Friday. The two female cubs belong to the Asiatic lion's species, one of the most endangered in the world. Rome Zoo officials said they were born in April and are in good health. Their birth represents a ray of hope for a highly endangered species. The International Union for Conservation of Nature (IUCN), an international body that classifies criteria for the study of endangered natural species, classifies the Asiatic lion, or 'Panthera leo' by their scientific names, as an endangered species.
