Toxin in saliva; functional when capturing prey, also functioning when being the
Urine-wash (scent-marking) for territorial purposes; chemical communication
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 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
