An orangutan from a zoo reintroduced to the wild in Borneo began spear fishing after watching local fisherman.
Orang-utans have confounded naturalists by learning to swim across rivers and to fish with sticks.
Gerd Schuster co-author of Thinkers of the Jungle: The Orangutan Report, took this photograph of, “a male orangutan, clinging precariously to overhanging branches, flails the water with a pole, trying desperately to spear a passing fish… The extraordinary image, a world exclusive, was taken in Borneo on the island of Kaja… This individual had seen locals fishing with spears on the Gohong River.Although the method required too much skill for him to master, he was later able to improvise by using the pole to catch fish already trapped in the locals’ fishing lines.”
