Lifestyle and Location:
- The Golden lion tamarin are native to the Atlantic coastal forests in Brazil and is an omnivore.
- Their fist activity of a day up to 12 hours is feeding on fruit and travelling, in the afternoon they start to find insects to eat rather than fruit. Then as night falls they go to their night dens, which change every day to minimise scent, thus making it harder for predators to find them.
- Their dens are hollowed out trees or dense vines and are used for sleep and are usually about 11-15 m off the ground.
- Their groups are between 2 and 8 members.
