Tarsiiformes is an order of primates that includes the family Tarsiidae, which consists of small, nocturnal animals known as tarsiers. These primates are characterized by their large eyes, which help them see in low light, and their long fingers and toes, adapted for grasping branches. Tarsiers are primarily found in Southeast Asia, inhabiting forests and woodlands. Tarsiers are unique among primates due to their diet, which mainly consists of insects and small vertebrates. They are known for their remarkable leaping ability, using their powerful hind limbs to jump between trees. Tarsiers are also notable for their distinct vocalizations and social behaviors, often living in small family groups.
