Articles relating to the Tarsiers (Tarsiidae), haplorhine primates of the family Tarsiidae, which is, itself, the lone extant family within the infraorder Tarsiiformes. Although the group was, prehistorically, more globally widespread, all of the species living today are restricted to Maritime Southeast Asia, predominantly being found in Brunei, Indonesia, Malaysia and the Philippines. They are found primarily in forested habitats, especially forests that have liana, since the vine gives tarsiers vertical support when climbing trees.
