He arrived at the Sanctuary in 2007, along with Táta and Judy. They had been living in a zoo in Fortaleza, northeast of Brazil, where they suffered a lot, especially after the zoo closed and fell into a precarious situation. They even experienced a lack of food and water. Additionally, they lived in an enclosure with little shade, forcing them to stay in the heat and suffer from thirst.

Peter is very strong, imposing, and has a different fur coloration compared to other chimpanzees, being more grayish all over his body. He is reserved but enjoys playing tag. Whenever he goes to get food to eat in the little house of his enclosure, he grabs several bananas and other fruits at once, perhaps due to having experienced hunger in the past and fearing being left without food.

He is the father of Marcelino, Miguel and Milan. Peter is an excellent father, taking very good care of his children, always interacting positively with them.
