  The gray woolly monkey (Lagothrix lagothricha cana) or Geoffroy's woolly monkey is a subspecies of the common woolly monkey from South America. It is found in Bolivia, Brazil and Peru. L. l. cana gets its common name, gray woolly monkey, from its thick gray coat. Its hands, feet, face and the inside of the arms are dark in color. The gray woolly monkey has been considered endangered by IUCN since 2008. The subspecies is listed as endangered because it suffered a 50% decrease in population over the past 45 years due to deforestation and hunting.
  
  ## Taxonomy
  
  Initially thought to be a subspecies of the common woolly monkey (L. lagothricha), it was later reclassified as its own species. Two subspecies of Lagothrix cana were known: L. c. cana and L. c. tschudii. L. c. cana in both Brazil and Peru and L. c. tschudii in southeastern Peru and in the Madidi National Park in Bolivia. However, a 2014 study supported reclassifying it again within L. lagothrica, with both subspecies being different subspecies of L. lagothrica.
  
  ## Habitat
  
  The gray woolly monkey predominantly lives in cloud forest, a type of forest under cloud cover for most of the year. They can be found anywhere from 1,000 to 2,500 metres above sea level. The population of gray woolly monkeys in Bolivia have been reported to be found as low as 700 metres above sea level. They spend the majority of their time high in the tree tops in search of food. They move through the trees using their large prehensile tails, which is a common trait seen in the family Atelidae. They are capable of hanging from their tails and often use them to bridge gaps between trees when travelling in them.
  
  ## Diet
  
  The gray woolly monkey predominantly eats fruit, but occasionally when fruit is scarce will eat young leaves and sometimes seeds.
  
  ## Groups
  
  Gray woolly monkeys live in groups of 11 to 25 members. These groups are of both mixed ages and sexes. The group will move together and show little aggression towards other groups, and will often share the best feeding spots with other groups.
  
  ## Size
  
  In general, males are larger than females. A male's head-body length ranges from 46 to 65 cm in length. A female's head-body length ranges from 46 to 58 cm in length. The tail length of the gray woolly monkey is on average from 66 to 68 cm in length. The male gray woolly monkey weighs an average of 9.5 kg. The female gray woolly monkey weighs an average of 7.7 kg.
  
  ## Threats
  
  The main threat the subspecies faces is hunting. They are hunted for food and pets. The females are often targeted for hunting as they are shot and then their offspring are taken and sold as pets. One story from the western Amazon reported several hunters who killed over 200 woolly monkeys in less than two years, which led to their local extinction. Deforestation is another major threat. Mining for cassiterite, a mineral used to make tin, is also a threat for both losing habitat and hunting.
  
  ## Conservation
  
  The gray woolly monkey is currently protected in many national parks. They are also listed in Appendix II of the Convention on International Trade of Endagenered Species (CITES).
