Our EAST capuchin group is the larger of our troops with 21 individuals, 12 males and 9 females, and is lead by dominant male Popeye. To help us learn who is who, we use features such as hair tuft shape and size, facial spots and markings, hair line shape and colouring, and general body size and head shape. See what differences you can spot between individuals below! Can you use these features to try and spot them in real life too?
