Macaca fascicularis
It is light brown or greyish fur and a long tail. A troop could comprise up to 30 individuals. Sometimes they disperse into small groups when they are out foraging. It is capable of swimming. Long-tailed macaques have several sleeping trees that they will go back to after they are done foraging for the day.
