Extra large congratulations are in order! Mara, a 10-year-old hippopotamus at the Los Angeles Zoo, has delivered a healthy calf—the first to be born at the zoo in 26 years. Because Mara was on birth control, the newborn came as a surprise to zoo workers, who suspected but could not confirm the new mama was expecting. What’s not surprising: How super cute the little mammal is. Zoo visitors can see the baby hippo (officials have yet to announce its name or determine its sex) and its parents in person daily.
