Limb adaptions allow for quick leaping locomotion between trees while capturing prey. The fossil record of tarsiers dates to between 34 and 56 million years ago, in the Eocene era (Zijlstra, 2013). As a result, the researchers suggest, the loriss markings resemble those of the snake, especially if the animal is encountered in the dusk of twilight, as one naturalist found out. Socialization includes grooming each other, scent marking, vocalizing (including duetting), and playing (Gursky, 1998).
