Primates are a diverse group of mammals that include humans, monkeys, apes, and lemurs. They are characterized by their flexible limbs, large brains relative to body size, and forward-facing eyes, which provide better depth perception. Primates are typically social animals, living in groups and exhibiting complex behaviors. There are two main suborders of primates: Strepsirrhini, which includes lemurs and lorises, and Haplorhini, which includes tarsiers, monkeys, and apes. Primates are found in various habitats, from tropical rainforests to savannas, and they play important roles in their ecosystems, such as seed dispersal and maintaining plant diversity.
