The primates vary in size from the mouse lemur, which is as small as 30 grams, to giant gorillas, which weigh upto 200 kilograms. More than 500 species of the primates are known, making them the third most diverse group of mammals after rodents and bats.
They have an increased brain size in comparison to other mammals. Their visual perception is also enhanced along with the sense of smell. However, both these features are more pronounced in apes and humans as compared to lemurs and lorises. They also possess claws on their digits along with flat nails. The bigger toe diverges from the other toes an...
All the species of primates have arboreal adaptations, but some of them such as gorillas, apes and humans are primarily terrestrial. The primates are unique as they are the most social of all animals, forming pairs and groups. The non-human primates also have different social systems that depend upon the movement of adolescent females. They are als...
They have forward-facing eyes such that their visual fields overlap. This feature is not special to primates but is seen in all predators. Their teethhave premolar and molar cusps that are low and rounded. This is in contrast with pointed cusps found in other placental mammals.
The arboreal primates living in forests can move by three methods: (a) leaping with the help of hindlimbs, (b) arm swinging with the help of forelimbs and (c) quadrupedalism with the help of both forelimbs and hindlimbs. Quadrupedalism is characteristic of baboons and apes whereas humans are bipedal.
The primates have a low rate of growth and development. They are breastfed by their mother and are totally dependent on them for the initial years of their life. In some cases, the young ones are carried by their fathers for transportation. The feeding mother temporarily ceases ovulation at the time of breastfeeding but regains her reproductive cap...
Primates devour a variety of food sources. They derive food from their natural environments such as fruits and vegetables. They include lipids, carbohydrates and proteins in their diet for energy and sustenance.
The primates tend to reproduce undergoing the following processes: breeding, gestation, birth and lactation. The primitive primates have an easy and short life cycle as compared to the advanced primates. The advanced primates have a longer gestation and juvenile period. In their juvenile period, they remain under the guidance of adults and thus get...

Jun 14, 2021 · Primates constitute an order of the class Mammalia of zoology that includes the lorises, lemurs, monkeys, tarsiers, apes, and humans. The order Primates contains more than 300 species, and it is the third most diverse order of class Mammalia after order Rodentia (rodents) and order Chiroptera (bats).
The Primates are an ancient and diverse eutherian group, with around 233 living species placed in 13 families. Most dwell in tropical forests. The smallest living primate is the pygmy mouse lemur, which weighs around 30 g. The largest is the gorilla, weighing up to around 175 kg.
