This May 15, 2018 photo provided by San Diego Zoo Global shows a researcher pointing to the newest ultrasound of Victoria, a southern white female rhino at the San Diego Zoo Safari Park in Escondido, Calif. The picture confirms what they've suspected for the past few weeks: she's pregnant. The rhino has become pregnant through artificial insemination at the zoo giving hope for efforts to save a subspecies of one of the world's most recognizable animals, researchers announce.
