The term "tarsianos" refers to a group of mammals known as tarsiers, which are small primates found in Southeast Asia. They are characterized by their large eyes, which help them see in low light, and their long fingers and toes, adapted for climbing trees. Tarsiers are nocturnal and primarily insectivorous, feeding on insects and small vertebrates. Tarsiers belong to the family Tarsiidae and are unique among primates due to their distinct evolutionary lineage. They have a unique ability to rotate their heads almost 180 degrees, allowing them to spot prey easily. Tarsiers are considered an important part of their ecosystems, contributing to pest control in their habitats.
