Common woolly monkey

The common woolly monkey, also called the brown woolly monkey or Humboldt's woolly monkey (Lagothrix lagotricha), is a large New World monkey of the upper Amazon basin, ranging from the Tapajós River in Brazil west through eastern Peru, Ecuador and Colombia, with scattered populations north to Venezuela. An adult measures 40 to 60 centimetres in head and body with a longer tail, weighs roughly 5.5 to 10.8 kilograms, and is diurnal. Its coat ranges from brown to grey or black, darker on the head and underparts, and the bare face is typically black. It is omnivorous but mainly a fruit eater, taking more leaves and insects when fruit is scarce, and it lives in groups of two to 70 that split into smaller foraging parties. The species is listed as Vulnerable by the IUCN, with road building, deforestation and hunting for food and the pet trade as the main pressures. Authorities now treat the gray, Colombian, silvery and Peruvian woolly monkeys as its subspecies.
