He arrived at Anami in 2002 and was kept separate from the others for safety reasons, since he was very young. However, on the day he was introduced, the surprise was immense and, contrary to what had been feared, the meeting resulted in strong embraces and positive interactions, showing that the integration was a success.

Matheus had the chance together free from the bars of a small, dirty circus cage, being able to grow and learn with other chimpanzees, an experience that was essential for his social development.

Today, he lives very well with his group and has great communication skills, including with the caregivers. He does not hesitate to ask for more food when he is hungry. He has become a beautiful and robust chimpanzee, now showing that he may be able to compete for a higher position in the hierarchy of the group he lives in.
