This week, just in time for the San Diego Zoo’s official reopening to the public on June 20, a 2-month-old male pygmy hippopotamus and his mother, Mabel, graduated from their maternity habitat to the larger main pygmy hippo habitat in the Lost Forest area of the Zoo.

Last month, after days of anticipation, Mabel, a 4-year-old pygmy hippopotamus at the San Diego Zoo, gave birth to her first calf.
