Overview
- Berlin Zoo said Tuesday that 13-year-old Nala delivered male twins about a week and a half ago, with one newborn dying shortly after birth.
- The surviving calf weighed 28 kilograms at birth, compared with the species’ typical newborn weight of around 40 kilograms.
- Zoo staff report close monitoring of nursing and weight gain to ensure the calf’s development.
- Nala has separated from the group for the early weeks of motherhood, which curators note is normal hippo behavior.
- The zoo highlighted that hippopotamuses are listed as threatened with increasingly fragmented habitats and sharp regional declines, including across much of the Nile.
