Tarsiiformes

Tarsiiformes is an infraorder of primates, commonly known as tarsiers. These small, leaping primates are found exclusively in Southeast Asia. Tarsiers are unique among primates for being entirely carnivorous, preying on insects, lizards, and snakes.1

Key characteristics include:
* Large eyes adapted for nocturnal vision.1
* Long ankle bones (tarsals), which give them their name.1
* A round head that can rotate 180 degrees.1
* A dry, hair-covered nose, distinguishing them from lemurs.1

Tarsiers are classified within the suborder Haplorrhini, alongside monkeys, apes, and humans, but form their own distinct infraorder. They are intermediate in some features between lemurs and monkeys.21
