Opposable thumb, and in most species, divergent big toe. Stereoscopic vision (we can see in 3-d: made possible by binocular vision (overlapping fields of vision) Decreased reliance on sense of smell: emphasis on usual communication. Dental formula: indicates the number of each type of tooth. Non-human primates and primate behaviour lecture 3 walking on 4 legs. Vertical clinging and leaping: some lemurs, tarsiers. Dental comb (modified incisors and canines) / toothcomb. Tarentum lucidum (eye shine on animals: dogs, cats have this, a structure in the retina allows eight to be reflected, the animal is likely to be active at night. Some practice infant parking : mouse lemur, potto, galago, ruffed lemur, ring-tailed lemur, sifaka. All have a rhinarium (must pad at lend of the nose) Olfaction plays a large role in their social communication: scent-marking (functions in temporality and/ or reproductive advertisement) Larger body size than pnosimians, and larger relative brain. No rhinarium, reduced reliance on smell size.
