Amahle, the San Diego Zoo’s youngest river hippo, is growing rapidly—and she’s already showing her curious side, exploring her habitat and seeking out new areas to investigate when her mom, Funani, isn’t right by her side.

A koala moved quickly out of a caretaker’s arms and up into a tall eucalyptus tree, while wildlife care specialists looked on. This koala is a member of an important group of the species that returned to their home in the Blue Mountains of Australia this past weekend. 

An 8-month-old koala joey being cared for round the clock by San Diego Zoo wildlife care specialists is thriving. The male koala joey, named Omeo (pronounced Ooh-me-ooh), lost his mother due to cancer in mid-December, when he was about 5-and-a-half months old and was still in her pouch.
