中猴是一种杂食性猴类，主要生活在岛上的丛林中。它比人类小，但它的行动速度和人类差不多。 它不像它的近亲巨猿那般好战，但在面对人类时，它们可能会因为人类过大的体积和缺少毛发的外表表现的害羞。 由于它们易受惊的个性它们很难被驯服。如果你有耐心的话，你可以用手喂食它们，但是贴近它们过长时间可能会使它们害怕的逃跑。
Common name: Mesopithecus
Species: Mesopithecus amicufur
Time: Late Miocene–Late Pliocene
Mesopithecus amicufur is an omnivorous monkey species, primarily inhabiting the Island's jungles. It is smaller than a human, but can scurry about the same speed. It does not appear to be aggressive unlike its relative the Gigantopithecus, but is rather very shy towards humans likely due to their much larger size and lack of hairy exterior. Due to their skittish nature they can be difficult to tame. They can be hand-fed if you are patient, but stick too close to them for too long and they'll get spooked and run away.
A common pet, Mesopithecus is very easy to keep fed. It will eat nearly any fruit harvested on the island. Mesopithecus is most often used as a social companion, as it cannot carry enough to be a beast of burden, is not large enough to be ridden and is not particularly good for combat. It is, however, quite effective at vocally warning of incoming intruders and pelting them with copious amounts of tossed fecal matter. Nomadic tribes have also managed to teach Mesopithecus to open locked doors when pillaging.
