Prosimians are a group of primates that include species such as lemurs, lorises, and tarsiers. They are considered the most primitive members of the primate order and are primarily found in Madagascar and parts of Africa and Asia. Prosimians typically have large eyes adapted for night vision, which helps them navigate their environments in low light. These animals are known for their unique behaviors and social structures. Many prosimians are arboreal, meaning they live in trees, and they often have strong limbs for climbing. They communicate through vocalizations, scents, and body language, showcasing a variety of social interactions within their groups.
