Capuchin is also known as sapajou.
Capuchins are very clever. They are good at cracking nuts -- something you may never expect. Normally, only we humans know how to create and use tools. How do capuchins make it? In fact, keepers have been giving enrichment and acclimatization trainings to these capuchins in the past few years in terms of environment, food and cognition. So an ordinary capuchin knows how to fetch food with a proper tool.
