Tarsier. Often referred to as the 'smallest monkey in the world,' the Tarsier, in fact, is more closely related to lemurs (prosimians) than to monkeys (anthropoids). Tarsiers belong to its own taxonomic suborder among primates. It is found mostly in Bohol, Samar, Leyte and Mindanao. It is variously known to the natives as 'mamag', 'mago', 'magau', 'maomag', 'malmag' and 'magatilok-iok'. The species has existed in the Philippines for 45 million years, or since the Eocene period. It is categorized as 'lower risk, conservation dependent.'
