Anthro2050 1st Edition Lecture 14Outline of Last Lecture I. Characteristics of PrimatesOutline of Current Lecture II. StrepsirhinesCurrent LectureStrepsirhines:- Live in South East Asia and Central Africa- Mostly nocturnal except for the lemurs- Have a tapetum lucidum; thick reflective membrane under the retina that maximizes available light for seeing better in the dark- un-fused mandible in the jaw and a dental structure called a tooth comb for grooming others- large mobile ears and a relative reliance on hearing- use scent to signal others and mark areas; scent glands in the genitals and on the wrists of some; also use urine for scent marking- have nails on their fingers and one claw on one finger for grooming- family laurisoidea (contains galagonidae and loridae)-Galagonidae-nocturnal to avoid conflict and contest with other primates in the area- ex. galagonidae; bush babies. very fast and leap through the trees-Loridae- nocturnal as well and move slowly through the trees- ex. loridae; slow loris. very slow and has poisonous saliva- family lemuridae (the lemurs)- non nocturnal unlike other strepsirhines- only found in Madagascar, where lack of predators allowed great diversification - ex. cheirogalidae; dwarf lemur, stores fat in its tail for the dry season- dauberitonidae; the aye aye, a genus and species all on its own. hunts by percussive foraging, using one long, skinny finger to tap on trees to listen for grubs then burrowing in the tree with its rodent like teeth and fishing the grubs out on the log finger.These 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.- Tarsioidea (Tarsiers)- border between strepsirhines and monkeys- live in South East Asia -are the only purely carnivorous primates, living off large insects- leapers with tarsal bone adaptations to allow for quick movement- their eyes are too big to move themselves, so they move their whole head up to 180 degrees around to see
