Here's the remarkable story of Jambo, a silverback gorilla at the Jersey Zoo. After a young boy, Levan, fell into the gorilla's zoo enclosure, fracturing his skull and breaking limbs, Jambo immediately came to his aid. The silverback stood firmly next to the young boy and even stroked his back in comfort, protecting the boy from danger. When Levan woke up and began to cry, Jambo lead his entire troop away so human rescuers could reach the boy.
