Video shows chimpanzees 'fishing' for algae
A video recorded by German scientists shows chimpanzees 'fishing' for algae using long sticks on a stream bed in Bakoun, Africa. Similar studies earlier conducted in the village have recorded chimpanzees using small twigs to collect algae on the surface of water. This had led scientists to the "discovery" that instruments chimpanzees use to extract food "varies" as per location.
