Coquerel’s Sifaka (Propithecus coquereli)
September 1 is World Primate Day, a designation intended to raise awareness about apes, monkeys, and prosimians like lemurs, lorises, and tarsiers. Many non-human primates are threatened by habitat loss, the pet trade, and hunting.
There are more than 440 species of primate worldwide, the majority of which live in the tropics.
The International Union for Conservation of Nature (IUCN) Red List classifies more than a third of primate species as critically endangered or vulnerable.
The following pictures show primates in a variety of sites around the world, including individuals in rescue centers, semi-wild habitats within protected areas, and the wild. All photos taken by Rhett A. Butler.
