Diversity of Living Primates
•All about Noses
•Strepsirrhini
•strepsi- turning inward
•comma shaped nostril on the rhinarium (wet nose!!!!)
•LEMURS & lorises
•Haplorhini
•haplos- one single fold, simple
•no rhinarium (no wet nose!!!)
•Platyrrhini
•Plat- flat
•flat nose
•new world monkeys
•Catarrhini
•Cata- hooked nose
•downward facing nose/nostrils
•both old world, and apes, and humans
•Lemurs (strep)
•type of locomotion:
•ring tailed- on the ground
•Brown- trees
•mostly four legs//upright body
•vertical clinging and leaping
•time of day active:
•day
•type of food:
•Physical characteristics:
•wet nose
•elongated snout
•long tails
•good at grasping
•mobile ears
•Whiskers
•closer to mammals than primates
•large primates: diurnal// smaller primates: nocturnal
•nails instead of claws- claw on second digit//retained for grooming purposes
•dental comb for grooming purposes
•general size:
•small//medium
•group or solitary:
• gregarious (group)
•some are solitary
•Adaptive radiation: evolved to inhabit multiple niches// therefore 100s of different lemur
species that vary in characteristics in the same place
•GORILLA SIZED LEMURS WAY BACK WHEN
•Lorises (strep)
•type of locomotion:
•Slender limbs for navigation
•long limbs for climbing
•Arboreal (lives in trees)
•Quadrupedal
•Climbers (:
•infant parking- leave young- cover infant in saliva- causes allergic reactions to
predators- predator spits out baby somewhere and goes away
•time of day active:
•nocturnal
•type of food:
•Fruits
•insects
•Physical characteristics:
•slender limbs (slender limbed loris)
•night vision // big eyes
•general size:
•tiny baby
•group or solitary:
•solitary
•fewer species of loris//africa, south asia//tropical forests
•Tarsiers (haplo)
•type of locomotion:
•leaps 15 feet
•trees//
•vertical clinging
•elongated feet for gripping
•time of day active:
•hunts at night
•Nocturnal
•type of food:
•Insects
•Physical characteristics:
•can’t move pupils lmfao has to move WHOLE head
•elongated feet and ankles
•eyes bigger than stomach and brain hehe
•Elongated feet for gripping
•long tails!
•big ears for very good hearing
•boney ring that protects eyes
•180 degree head range
•general size:
•tiny baby
•group or solitary:
•Gregarious- families of 8
•pair bond
•TARSIIFORMERS- tarsioidea
•ONLY 5 species of these left in the world
•found in south east asia//Philippines
