Primate - member of the mammalian order Primates, which includes humans, apes, monkeys, and prosimians, or lower primates.
Prosimians: Primitive Primates
Prosimians are "primitive" primates that once ranged the world over-at least in the tropical rain forests-until monkeys and apes came along and out-competed them.
in the tropics or subtropics, and most depend on forests for their survival. Primates share characteristics-such as five-fingered hands with opposing thumbs, forward-facing eyes, and color vision-but they do vary greatly, especially from prosimian to ...
Prosimians
Cheirogaleidae: Dwarf lemurs
Lemuridae: Large lemurs
Megaladapidae: Sportive lemurs
Indridae: Leaping lemurs
Daubentoniidae: Aye-Aye
Loridae: Lorises and galagos
Tarsiidae: Tarsiers ...
Prosimians have:
A well developed sense of smell, and a more prominent snout.
Partial binocular vision (using two eyes together, as apes and monkeys do). Often nocturnal vision.
Some claws and developed manual dexterity.
Immobilized upper lips.
Prosimians are restricted to tropical woodlands. Many surviving species have become nocturnal, a habit that has been acquired because they have become withdrawn by competition from monkeys and rodents.

*** Prosimians such as the ruffed lemur cannot manipulate their fingers well enough to use them for grooming, as most monkeys and apes do. Instead of using their fingers, all prosimians have a toothcomb which is made up of their 6 bottom teeth.
These prosimians are quite social and the groups have clearly defined male and female hierarchies. Most communities number 2-5 individuals.

A female lemur carries her newborn to a new nest site in her mouth.
These small prosimians (primitive primates) are nocturnal and arboreal. The name slow loris refers to their deliberate movements that are very much like a chameleon.
In a study of prosimian cognition conducted in 1964, Pottos were seen to explore and manipulate unfamiliar objects, but only when those objects were baited with food.
This prosimian is a subspecies of the black lemur. Males are black while females have rufous to tan (and sometime gray) coats dorsally and on the tail, an off-white ventrum, a reddish beard, and dark extremities.
Order Primates has traditionally been divided into two main groupings: prosimians and anthropoids (simians). Prosimians have characteristics more like those of the earliest primates, and include the lemurs of Madagascar, lorisiforms and tarsiers.
Primates include prosimians, monkeys and apes. Primates inhabit tropical regions throughout Central America, South America, Africa, Madagascar and east and southeast Asia.
To the best of our current knowledge the first primates evolved between 60 and 70 million years ago with genera like Plesiadapis, within about 10 to 20 million years this early group had split into sections, the prosimians which gave rise to Lemurs ...
Small primates include monkeys and 'prosimians,' meaning 'pre-apes.' More monkey species and subspecies-at least 200-live in the New World (South and Central America) than anywhere else.
Along with rescuing animals from the pet trade, the food market, and other peril, the rescue center protects and conserves Vietnam's 24 types of primates and their cousins, the prosimians.
Estivation: Torpor occurring during summer when drought and/or reduction in food supply may make survival problematic (some rodents and some small prosimians).

The Central Florida Zoo is involved in 22 Taxon Advisory Groups for amphibians, apes, canids, crocodilians, felids, lizards, New World primates, parrots, prosimians, snakes, and terrestrial invertebrates.
