Orang-utans have confounded naturalists by learning to swim across rivers and to fish with sticks.Naturalists were shocked to see the apes swim across a river to gain access to some of their favourite fruits at a conservation refuge on Kaja island in Borneo. Orang-utans were previously thought to be non-swimmers. The wildlife experts were equally surprised to see an orang-utan pick up a tree branch and stun a fish before eating it. Other apes introduced to the island were seen trying to spear fish with sticks after watching fishermen using rods. The naturalists also noted that the apes quickly worked out that it was even easier to steal fish from unattended lines used by the humans on the island.
These things are pure geniuses. No doubt. 1000% smarter than dolphins. Its only a matter of time before these things are working in a sweat shop making my jeans.
