The Uakari Vermelho (Cacajao calvus) is a small monkey with a very short tail, red face, a bald head, and long coat. It generally weighs less than 9 pounds and is anywhere from about 20 to 23 inches in length. The Uakari Vermelho is found in the wet forests of the Amazon River. Their scarlet red faces are due to the lack of skin pigments and plentiful capillaries that run under their facial tissue. This bright red facial skin is a sign of good health and allows for the determination of a healthy mate. The Uakari Vermelho lives approximately 20 years. The overall diet consists of seeds, fruit, flowers, animal prey, and will also eat insects that happen to be cross their path.
