Lemurs, lorises, tarsiers

Lemurs, lorises, tarsiers, and New World monkeys rely on olfactory signals for many aspects of social and reproductive behavior.[4] Specialized glands are used to mark territories with pheromones, which are detected by the vomeronasal organ; this process forms a large part of the communication behavior of these primates.[4] In Old World monkeys and apes this ability is mostly vestigial, having regressed as trichromatic eyes evolved to become the main sensory organ.[91] Primates also use vocalizations, gestures, and facial expressions to convey psychological state.Marriage Workshop girls charm bracelets[92]
