AN ORANGUTAN LEARNED HOW TO SPEAR FISH BY WATCHING HUMANS DO IT!

AN ORANGUTAN LEARNED HOW TO SPEAR FISH BY WATCHING HUMANS DO IT!
The first time an orangutan was documented using a tool was in 1994,
when Carel van Schaik observed orangutans developing tools to help themselves eat.

They were using sticks to pry open fruit that had some needles that were in the way of the actual food part of the fruit.

In the jungles of Borneo, scientists observed an orangutan spear fishing (look at the picture below). Apparently this orangutan had seen (human) locals spear fishing on the river and attempted to do the same.

Apparently, the method required too much skill for him to master, but he was later able to improvise by using the pole to catch fish that were already trapped in the locals' fishing lines.
