The majority of primates live in South and Central America, Africa, and southern and Southeast Asia, in a variety of habitats, particularly forests but also including grasslands, savannas, shrublands, wetlands, deserts, and rocky areas.
The exact organization of the species is not fixed, with many recent proposals made based on molecular phylogenetic analysis.
Ranges are based on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species unless otherwise noted.

Members of the Hominidae family are hominids, or colloquially great apes, and include gorillas, chimpanzees, orangutans, and humans.
Members of the Pitheciidae family are pitheciids, and include titis, saki monkeys and uakaris.
Pitheciidae comprises 55 extant species in 5 genera, and is divided into the subfamilies Callicebinae, or titis, and Pitheciinae, or saki monkeys and uakaris.
Members of the Indriidae family are indriids, and include woolly lemurs, sifakas, and indri.
Members of the Lemuridae family are lemurids, and include ring-tailed, true, ruffed, and bamboo lemurs.
Lorisidae comprises sixteen extant species in five genera, and is divided into the subfamilies Lorisinae, or lorises, and Perodicticinae, or the angwantibos and pottos.
