Primate Behavior and Ecology
Primate Characteristics
Mammals, not pets; differ from most mammals by having grasping hands and feet, collarbone (Clavicle),
radius and ulna, forward facing eyes and stereoscopic vision (depth perception)
Dangerous, belong in the wild; diseasesdisastrous; visually oriented
Activity patterns: nocturnal (active at night), diurnal (active during day), crespuscular (active at dusk and
dawn), cathemeral (active any time of day or night)
Diets: frugivore (fruit), folivore (leaves), insectivore (diet of insects), graminivore (diet of small seeds and
grasses), faunivore (invertebrates and vertebrates), gummivore (tree exudates), graminivore (small seeds
and grasses), seed predator/schelerocarpivory (hard seeds), omnivore (varied diet)
Primate Taxonomy
Order -> suborder -> infraorder
Strepsirhine characteristics: dental tooth comb, moist rhinarium, unfused manibular and frontal sympases,
taetum hicidum, postorbital bar
oTwo superfamilies:
Lemuroidea: Madagascar and Comoro islands, Arboreal quadrupeds and leapers, some
partially terrestrial, many small-bodies species are nocturnal, females dominance, varied
diet
Lorisoidea: found throughout sub-Saharan Africa and Southeast Asia, Lorises and
galagos, Arboreal quadrupeds, nocturnal, varied diet
Legend: lemurs sad about lorises taking their tail; contrasting cries/calls
Lemurs endemic to Madagascar
Haplorhine characteristics: dry nose, retinal forvea, postorbital closure, fused mandibular and frontal
symphases (cf Tarsiers)
oThree infraorders
Tarsiiformes: one genus (Tarshius), found in SE Asia, small body size, relatively large
eyes, with fused lower leg bones, entirely faunivorous
Platyrrhines: (Neotropical mokeys), medium size, central and south America, cebidae,
atelidae and callitrichidae, prehensile tail in few species, most entirely arboreal (look like
old tropical European colonists)
Catarrhines: (Old World monkeys and apes), Africa, Asia and SE Asia, big,
cercopithecidae, hylobatidae and hominidae, varied diets, social organizations and
adaptations (mates for lifetime but sometimes “cheat….)
