Eastern gorilla
There are two recognised subspecies of eastern gorilla: the mountain gorilla ("Gorilla beringei beringei") of the volcanic slopes of Rwanda, Uganda and eastern Democratic Republic of Congo; and Grauer's gorilla or eastern lowland gorilla ("Gorilla beringei graueri") in eastern Democratic Republic of Congo.
Caratinga
Some 150 northern muriquis (Brachyteles arachnoids) live today at the Fazenda Montes Claros, near Caratinga. It is one of their last refuges. The muriqui is the largest monkey of the Americas and one of the most endangered primates of the world. Specialists cite the biological importance of the Fazenda Montes Claros, where three other primate species live along with the muriqui: the buffy headed marmoset, the black-capped capuchin and the brown howler monkey.
