Primates of  Southeast Asia

Worldwide there are more than 450 species of primate. In Southeast Asia, as of 2016, there are 96 species recognised, comprising 19 species of prosimian (represented in the region by Lorises and Tarsiers), 56 species of Old World Monkey (including macaques, and colobines such as lutungs, surilis, doucs and others), 18 species of gibbon and 3 great apes (including humans).  In evolutionary terms, prosimians are considered to represent ancient lineages of primate, and great apes the most advanced.  Ecologically, primates play an important role as seed dispersers in the region's forests.
