3 Strepsirhines Malagasy Strepsirhines Characteristics: –dental tooth comb –grooming claw on second digit of feet –postorbital bar –no postorbital closure –most have a mandibular symphysis –unfused frontal bone –variations in foot anatomy related to locomotion

4 Cheirogaleidae 5 extant genera Examples: –Pygmy Mouse Lemur (Microcebus myoxinus) –Coquerel’s Dwarf Lemur (Mirza coquereli) –Fat-tailed Dwarf Lemur (Cheirogaleus medius) Characteristics: –Average weight ranging from kg –Nocturnal –Arboreal quadrupeds –Microcebus myoxinus is smallest living primate –Cheirogaleus medius hibernates for up to 6 months –Most females only receptive to mate for a few hours each year Pygmy Mouse Lemur Dwarf Lemur Fat-tailed Dwarf Lemur

5 Lemuridae 4 extant genera Examples: –Ring-tailed Lemur (Lemur Catta) –Ruffed Lemur (Varecia variegata) –Gray Bamboo Lemur (Hapalemur griseus) Characteristics: –Average weight ranging from kg –Diurnal –Mostly arboreal quadrupeds –Hapalemur uses some Vertical Clinging and Leaping (VCL) Ring-tailed Lemur Bamboo Lemur Ruffed Lemur

6 Lepilemuridae 1 extant genus Examples: –White-footed Sportive Lemur (Lepilemur leucopus) Characteristics: –Average weight ranging from kg –Nocturnal –Vertical Clingers and Leapers (VCL) –Reingests its feces to get broken-down cellulose Sportive Lemur

7 Indriidae 3 extant genera Includes: –Woolly Lemur (Avahi) –Sifaka (Propithecus) –Indri (Indri indri) Characteristics: –Average weight ranging from kg –Specialized leapers with long hindlimbs, feet, and hands –All specialized VCL’s –Avahi is nocturnal –Propithecus moves bipedally on the ground –Indri has no tail Sifaka Indri

8 Daubentoniids Aye-aye (only extant species) Characteristics: –enormous ears –rodent like incisors –large clawed digits, except for hallux –third digit is extremely long and slender –nocturnal –quadrupeds

9 Strepsirhines Includes: –Galagidae (bushbaby) –Lorisidae (potto, slow loris, and slender loris) Characteristics: –grooming claw on the second digit –nocturnal –arboreal quadrupeds –dental tooth comb Mainland Africa Strepsirhines Galagos and Lorises Lorises Galago Loris

10 Galagos and Lorises Examples of Galagos: –Greater Bushbaby (Otolemur garnetti) –Senegal Bushbaby (Galago senegalensis) Characteristics: –Average weight ranging from kg –elongated calcaneus and navicular bones –VCL’s –Demidoff’s Bushbaby one of the smallest living primates Examples of Lorises: –Slender Loris (Loris tardigradus) –Slow Loris (Nycticebus coucang) Characteristics: –Average weight range from kg –Slow and stealthy quadrupeds Greater Bushbaby Slender LorisSlow Loris
