What are the three types of primates?

There are not just three types of primates, but rather three suborders within the order Primates:

1. Strepsirrhini: This suborder includes lemurs, lorises, and galagos. They are characterized by a wet nose, a tooth comb, and a grooming claw.

2. Haplorhini: This suborder includes tarsiers, monkeys, and apes. They are characterized by a dry nose, a lack of a tooth comb, and a lack of a grooming claw.

3. Platyrrhini: This is a parvorder (a group smaller than a suborder) within Haplorhini, which includes New World monkeys. They are characterized by a prehensile tail, which they use for grasping.

So, while the three suborders are Strepsirrhini, Haplorhini, and Platyrrhini, you can also group primates by parvorders:

* Strepsirrhini

* Haplorhini

* Platyrrhini (New World monkeys)

* Catarrhini (Old World monkeys and apes)

It's important to note that these classifications are based on shared physical and genetic traits, and the relationships between different primate groups are constantly being revised as scientists learn more.
