LorisoidsVI. HaplorhinesVII. TarsiersCurrent LectureI. Ancestral Mammalian Traitsi. Haira. Conserves body heatii. Five digitsiii. Mandible is a single bonea. 2/3 bones of the middle ear were once part of the mandible and skull of reptilesiv. Unfused mandiblea. In some mandibles, the mandible remains unfused for their entire lifetimev. Live birtha. Except the most primitive mammals (spiny anteater and platypus), which areegg-layingvi. Bicornuate uterusa. 2 horns to a uterusvii. Multiple nipplesa. Nurse multiple offspring at onceThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.viii.Tapetum luciduma. Reflective eyes in animalsix. Rhinariuma. Wet noseb. Split upper lipII. What traits distinguish primates from mammals?i. Enhanced vision: eyes rotated toward the front (converged orbits)ii. The presence of postorbital bara. Bar bone surrounding outside of the eyeiii. Grasping hands and feeta. All primates have a nail on their big toe (hallux), rather than a clawb. Most have nails on all of their digitsc. Primate hands are exceptionally dexterousiv. Reduced sense of smell (olfaction)v. Large complex brainsIII. Organizing primatesi. Prosimians vs anthropoidsii. Strepsirrhines vs haplorhinesa. Derived strepsirrhine traits:1. Tooth comb2. Grooming claw on second digitIV. Lemuroidsi. Geographic distribution: all live on the island of Madagascarii. Body size range: 1 ounce – 15 poundsiii. Activity pattern: most diurnal (day), some Nocturnal (night)iv. Locomotion: arboreal and terrestrial quadrupeds, vertical clingers and leapersv. Diet: fruit, flowers, gums, leavesvi. Separated in 5 major groupsvii. Five groups of lemuroidsa. Lemurids1. Ring-tailed lemura. Very large groups, long striped tails, scent glands, territorial2. Brown lemur3. Black and white ruffed lemur4. Eastern lesser bamboo lemurb. Lepilemurids1. Sportive lemura. Short, big eyesc. Indriids1. Indria. Long legs2. Sifakad. Cheirogaleids – mouse-like1. Fat-talied dwarf lemura. Store fat in tail2. Mouse-lemure. Daubentoniids1. Aye-ayeV. Lorisoidsi. Geographic distribution: Africa and Asiaii. Body size range: 2 oz – 3.5 poundsiii. Activity pattern: all nocturnaliv. Locomotion: arboreal quadrupeds, slow climbers, vertical clinging and leapingv. Diet: fruit, gums, and insectsvi. 2 groupsvii. Groups of Lorisoidsa. Galagos1. Mohol bushbaby2. Thick-taled bushbabyb. Lorises – bite can be venomous1. Pottoa. Small second digit2. Slow loris3. Slender lorisVI. Haplorhinesi. Dry external nose, fused upper lipii. Loss of the rhinarium, tapetum lucidumVII. Tarsiersi. Geographic distribution: southeast Asiaii. Body size range: all around 3.5 oziii. Activity pattern: all nocturnaliv. Locomotion: vertical clinging and leapingv. Diet: insects, small animalsvi. One genus with many speciesvii. Large eyes – lack tapetum lucidum even though they are
