Gaylene Thomas, a wildlife care manager at the San Diego Zoo, oversees two teams that care for a variety of species, including leopards, tigers, hippos, giraffes, deer, the giant pandas and red pandas. Among those animals are also some of the zoo’s newest babies: twin sloth bear cubs and two koala joeys.

The San Diego Zoo is celebrating the birth of its newest addition to the sloth family. It is the third baby for Xena, a 12-year-old sloth who has two other children, Tornero and Colheita. Some significant time has passed since the zoo last welcomed a sloth pup.
