Document Summary
Primates are mammals (warm-blooded, having hair and feeding milk to young) Primates differ from most mammals by having. Forward-facing eyes and stereoscopic vision (these traits allow us to have depth perception) Cathemeral: active any time of day or night. Most primates eat a variety of fruits, leaves, insects, flowers, and leaves. A few species specialize by eating mostly or only leaves, which requires special gut adaptations, or insects. Generally, larger-bodied species can eat more leaves whereas smaller-bodied species can eat more insects. Tapetum lucidum (an extra reflective layer in the back of the eye that allows them to see good at night) Postorbitol bar (behind the eye orbital bar) Three infraorders: tarsiiformes, platyrrhines(neotropical monkeys), catarrhini (old world monkeys and apes) Use of forelimb almost entirely for manipulation, carrying and throwing; rarely used for locomotion. Scaling: area (lxw) and volume (lxwxd) change at different rates. Animal doubles in size will be eight times heavier.
