10- Primates

Original air date: 20 March 1979

As the image below shows this episode is about intelligence among non-human primates

Selected material

White-faced capuchins (monkeys)

The capuchins find it hard to open the shell so they tire the muscles of the clam by rolling it along the branches (left) or knocking it (right)

At last they can open it easily and enjoy their prize
