Oh god the copper one.
Shomili, a four-month old greater one-horned rhinoceros, or Indian Rhino, runs behind her mother Sundari at San Diego Zoo Safari Park. Shomili, or “Mili” as zookeepers call her, was released into the park’s Asian Savanna habitat to join the rest of the zoo’s herd on April 23, 2013. Mili is the 65th greater one-horned rhino born at the zoo, which is working to conserve this endangered species. Only about 3,400 of these rhinos survive in the wild.
