Red colobus monkeys

Red colobus monkey

Red colobus monkeys (genus Procolobus or Piliocolobus) live along the equator in Africa. They come in many different colors in addition to the reddish black that gives them their name. They often have whitish or grayish faces and chests, with the deep red color appearing only on their back, crown of the head, paws, and tip of the tail. This color variety has made these monkeys difficult to classify, and there is considerable disagreement in their grouping. Red colobus monkeys have a head and body length of 17.7-26.4 in (45-67 cm), a tail length of 20.5-31.5 in (52-80 cm), and weigh 11.2-24.9 lb (5.1-11.3 kg). These monkeys have no thumb at all, lacking even the small vestigial thumb seen in black and white colobus monkeys.
