2. Mammal Characteristics
endotherms – warm blooded 4 chamber heart fur/hair breast (mammary glands, milk) “care for young” behavior lungs with diaphragm advanced nervous system (complex brains for problem solving) highly developed senses (large eyes, sonar, smell sensitivity)

4. Mammal Adaptations
Teeth Adaptations: Incisors: cut Canines: tear, slash Molars: grind Cold Environment Adaptations: to keep warm Food (higher in calories, meat or fish) Fur/hair Fat Movement Adaptations: walk, run, hop, swing, glide, swim (w/ flippers)

5. Three (3) Mammal Groups
Monotremes- lay eggs ex: spiny anteater, duck-billed platypus Marsupials – partly developed young live in a pouch. ex: koala bear, kangaroo, opossum Placental Mammals – develop inside mothers body; diverse, subdivided based on eating and movement ex: carnivores (eat meat), marine (swim), rodents (gnaw), rabbits/hare (hop), trunk, insect eaters, toothless, hoofed, flying (wing), primates (large brain)
