80.2. Representative Species: Jawless fish
81. Class Chondrichthyes

82.2. Representative Species: Tuna
83. Class Amphibia

83.2. Representative Species: Frogs
84. Class Reptilia
84.1. Reproduction involves internal fertilization, which protects the egg and sperm from drying. To be truly free of water it is necessary to have a specialized aquatic environment in which the embryo develops.
84.2. Lizards
85. Class Aves
85.1. Like the structures of their reptile ancestors, the skin, lungs, and kidneys of birds reduce water loss, and reproduction involves internal fertilization and the shelled amniotic egg.
85.2. Representative Species: Birds
86. Class Mammalia
86.1. At the time of the vast extinction of reptiles, mammals began to diversify and became the dominant forms of vertebrates on land.
86.2. Representative Species: Humans
87. Monotremes
87.1. Lay eggs
87.2. Incubate them like birds
87.3. Have mammary glands and make milk
87.4. Long periods of maternal care
87.5. 1 offspring/year
88. Marsupials
88.1. Highly altricial young
88.2. Short gestation (8-43 days)
88.3. Young born extremely small relative to adult size
88.4. Why is it superior to Monotremes: A marsupial is a mammal that has a pouch in which to carry their young. Marsupials generally give birth earlier that placental mammals. They have very strong limbs because they have to climb to the mothers nipples to feed.
89. Placental
89.1. Placenta develops during pregnancy.
89.2. The placenta sustains the fetus while it grows inside the mother’s uterus.
89.3. Placental mammals give birth to relatively large and mature infants.
89.4. Why is it surperior to Marsupials: A placental mammal is a mammal that is nourished in the mother's uterus and born developed. This is a very diverse group and consists of whales, cats, dogs, and humans, etc.
