Two male African elephants born at the San Diego Zoo Safari Park—Emanti and eMacembe LaLu Hlata, better known as “Mac”—are now residing at the Caldwell Zoo in Tyler, Texas.

Chimpanzees are well known for their extraordinary diversity of behaviors—including using tools for hunting or digging, cracking nuts with stones and using moss as a water-drawing sponge—with some behaviors also exhibiting cultural variation.
