A gorilla dove into a 16-foot moat to rescue her younger sister at Israel's Ramat Gan Safari. Eight-year-old Anya carried three-year old Amelia on her back after the latter fell into the ditch. After initially struggling to climb out of the moat, the pair managed to climb out the side of the moat into the visitor's area.
