18. REPTILES Thick, dry skin Ectotherms Lungs to breathe Evolved 35 mya Strong vertical legs Most lay thick rubbery eggs. This allows them to reproduce on land

19. Reptile eggs Shell - protects the egg Albumen – provides water and protein Amniotic sac - protects embryo Yolk - provides food Allantois – stores waste and passes oxygen

20. Labeling the egg

21. Lizards About 4,000 species Live in deserts, jungle, forests and grasslands Most eat small invertebrates and plants but some are strictly herbivores The tail of some lizards separate from the body when the lizard is grabbed. The tail that is left behind wriggles, confusing the other animal.

31. Adaptations Beak – cracking, drilling Feet – wading, scratching

32. Which food goes with which bird?

33. A few feet good for perching good for swimming good for capturing prey

34. Respiration Air sacs - give constant oxygen (fuel) - give enough energy for flight lungs

35. Circulation Double-loop circulatory system keeps oxygenated blood separate from de- oxygenated blood

36. Bones Birds have “hollow” bone that makes them lightweight Have trusses inside bone for strength

37. Complex Behaviors Song - protects territory - mating - calling Migrate

38. Flight adaptations Feathers and wings Hollow bones Keel and strong flight muscles Large eyes Increased heart rate Increased respiration High body temperature

43. 5 Characteristics of all Mammals Hair Mammary Glands and a diaphragm Most Sweat Endothermic

44. Three Classes Monotremes Marsupials Placental

Marsupials Pouched Inside pouches are mammary glands Infants are born not fully developed and move to pouch to finish development Different age babies can live in pouch at the same time Live mostly in Australia, New Guinea, and South America Kangaroos, opossums, koalas, Tasmanian devils, wallabies

47. Placental Most mammals are placental Embryos stay inside mother until fully developed Babies are born like smaller adults Placenta are special attachments from embryo to uterus Placenta supplies food and oxygen Placenta also removes waste Gestation period is the time it takes for an embryo to develop Gestation ranges from a few weeks to almost 2 years depending on the species
