These cute little monkeys are Capuchins - name so because they look like cappuchino coffee. We saw them on a boat trip on Lake Gatun, the man made lake supporting the Panama Canal. We parked our little boat and they became quite curious - eventually finding a peanut on our boat. At one point I reached up to touch one and it slapped my hand hard. We were told NOT to smile because it appears as an agressive teeth baring gesture the monkeys use to fend off each other and predators. Cute AND wild.
