In lowland rain forests from Mexico to South America, along Amazon coasts, and Andes mountain slopes, spider monkeys live above in forest canopies. They eat mainly ripe fruit, adding leaves, flowers, seeds, nuts, insects and eggs to their diet. They mark their territory with glandular secretions and defend it with screams, barks, and throwing objects. Endangered for their fur and meat, Spider monkeys are diurnal, non-aggressive and social, but only share habitat with other diurnal monkeys.
