Sec 4 Flashcards
Very few primates are adaptive rule-breakers
False
None of the anthropoids weigh less than 500 grams.
false
Like lemuroids, platyrrhines evolved in isolation from all other primates.
True
The primates of the Semiorder Haplorhini, Suborder Anthropoidea, and Infraorder Platyrrhini include the Superfamily_______ (with odd-faced New World monkeys) and the Superfamily______ which includes the rest of the New World monkeys.
Ceboidea and pithecoidea
The Subfamily Callicebinae is represented by one genus with 30 species.
True
The Subfamily Pitheciinae includes 3 genera of aptly named “odd-faced” monkeys!
True
The Family Atelidae holds the only fully prehensile-tailed primates. These monkeys happen to be the largest platyrrhines in body mass.
True
Spider monkeys, squirrel monkeys, and howling monkeys have fully prehensile tails.
False
Both howling monkeys and wooly monkeys have schizodactyl hand but spider monkeys and muriqui monkeys lack thumbs!
true
The Superfamily Ceboidea has two Families – the Atelidae which includes the only fully prehensile-tailed monkeys and the Cebidae which include one subfamily of semiprehensile-tailed monkeys, one subfamily with the only nocturnal anthropoid, and one family of highly-specialized monkeys with the smallest body weights of all platyrrhines and anthropoids.
True
Including all of the capuchin genera together – these monkeys are known for allogrooming, tool-use, and general busy-bodied brainiest. This has helped to make the “organ grinder” monkey a favorite of casting directors for Hollywood films.
true
Squirrel monkeys, like owl monkeys, live in small family groups.
false
Owl monkey nocturnality is particularly unusual because they are descended from a diurnal ancestor and retain its retinal fovea. An additional interest fact is that they only have one type of visual sensory cell and are, as a result, color blind!
True
Marmoset and tamarin dietary adaptations include tegulae (claw-like nails) that enable vertical climbing on tree trunks. Some taxa engage in “crop-rotation” and one species is the smallest-bodied modern primate.
true
The Superfamily Cercopithecoidea has one Family – the Cercopithecidae. Cercopithecids are represented by cheek pouch monkeys in the Subfamily Colobinae and complex stomach monkeys in the Subfamily Cercopithecinae.
