SLIDE LORISES:
๎€Toxin in saliva; functional when capturing prey, also functioning when being the
prey itself
SLIDE GALAGOS:
๎€Urine-wash (scent-marking) for territorial purposes; chemical communication
SLIDE TARSIERS:
๎€Faunivore; not only eats insects, but can also eat small birds, lizards, can capture
small vertebrates. Only carnivorous primate, no plant matter
๎€No tapetum lucidum; general characteristic because they lack that protective layer,
hence why eyes are so big
๎€VCL locomotion, called a tarsier because of their elongated tarsal bones
๎€Locomotion: vertical clinging and leaping
PRIMATES AND SUBORDER SLIDE: KNOW BOTH CLASSIFICATIONS!
PROSIMIANS VS. ANTHROPOID, AND STREPSIRHINES VS. HAPLORHINES
๎€Tarsier; even though they are categorized under prosimians, tarsiers have mixing of
maternal and fetal blood. Should be categorized as anthropoids
๎€2 Suborders: StrepsirhinesHaplorhines
Tarsiers
๎€Tarsiers do not have a rhinarium (moist nose)
๎€*Haplorhines do NOT have rhinarium, but Strepsirhines DO
SLIDE ANTHROPOID CHARACTERISTICS:
๎€We have a very poor sense of smell vs. prosimians
๎€Increased parental care; would never park infants!
SLIDE ANTHROPOID CHARACTERISTICS 2:
๎€Increased gestation (pregnancy) lengths, longer time to reach sexual maturity
