Zanzibar red colobus (Procolobus kirkii) is a monkey that lives only on Zanzibar, an island off the coast of Tanzania. They are an endangered species with no more than 3000 left in the wild. The people of Zanzibar hold negative views of the animal and call them `poison monkey’ because of their unusual smell. They live in groups of up to 50 individuals, with a 1:2 ratio of males to females. The red colobus eats leaves, seeds, and flowers that it finds in forests, coastal areas, and swamps. They also eat unripe fruit because they cannot break down the sugars in ripe fruit. They are known to eat charcoal to aid digestion.
