All About Primates
From small lemurs to large apes – everything about these clever animals with their skillful grasping hands!
What Are Primates?
Primates are mammals. This group includes the great apes, such as chimpanzees, gorillas, and orangutans – our closest relatives! Primates stand out from other mammals because they have hands with fingers and thumbs, allowing them to grasp and hold objects effectively. Many primates inhabit forests and enjoy climbing trees. They are highly intelligent, capable of problem-solving and using tools. Primates are generally very social and care for one another – they even groom each other.
Main Characteristics of Primates
1. Highly Developed Brain
In relation to their body size, primates possess a large brain. However, this alone does not indicate intelligence. It is primarily about the structure. In primates, certain areas of the brain are particularly well-developed: the cerebral cortex and the frontal lobe. These regions are crucial for tasks that require advanced thinking. Additionally, primates have a high number of nerve cells and synapses. This combination makes all the difference!
2. Grasping Thumb
Primates have five fingers – just like us humans. Most also have a thumb. This is quite special, as nearly all other animal species lack a thumb (except for pandas, koalas, raccoons, and opossums). What is the purpose of a thumb? For grasping! Without them, we humans would struggle to hold objects with our hands. Or even to support ourselves when we are unsteady. When we use our index finger and thumb together, we can also grasp small items – just like with tweezers.
3. Forward-Facing Eyes
Primates possess forward-facing eyes, a rarity in the animal kingdom. Only predators share this trait. These eyes allow for depth perception and assist in accurately judging distances—crucial for activities like climbing, hunting, or jumping. Additionally, primates have a highly developed visual center in their brains, enabling them to see colors as well.

Amazing Facts About Primates
- Primates are mammals. There are about 500 species.
- Primates are omnivores. They mainly feed on plants, fruits and insects.
- Primates have an opposable big toe. This means it can be placed opposite the other toes.
- In many primates the thumb is opposable, too. They can grab objects with precision using their thumb and forefinger (“pinch grip”).
- Primates usually have fingernails and toenails instead of claws.
- Primates (and koalas) are the only mammals that have fingerprints.
- Primates live in tropical and subtropical regions in America, Africa and Asia.
