For the first time in San Diego Zoo Global’s history, an echidna (ih-KID-na) baby—or puggle, as they are called—has hatched at the San Diego Zoo Safari Park.

In between eating her morning meal, a 7-week-old cheetah cub played and pounced in an indoor nursery area at the Ione and Paul Harter Animal Care Center, at the San Diego Zoo Safari Park.

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.

Ever wanted to know how long a hippo can stay underwater? How they “dance” so gracefully through the water? Or how long they sleep?
