18 Mammal Orders There are 19 orders of mammals in the class Mammalia in which 17 nourish unborn young in the placenta, egg laying mammals and marsupials

19 Monotremes and Marsupials Only 5 percent of all mammalian species are in the orders Monotremata and Marsupialia.

20 Monotremata Oviparous or egg laying mammals Only 3 in existence Duck-billed platypus and two species of spiny anteaters called echidna. Not completely endothermic (their body temperature is lower and fluctuates more than other mammals )

21 Marsupials Marsupials give birth to tiny immature young that crawl to a pouch on the mothers belly immediately after they are born.

22 They attach themselves to milk secreting nipples nursing until they are mature enough to survive outside the pouch.

species of marsupial species exist in Australia, New Guinea, Tasmania, And the Americas. Tasmanian Devil

24 American Marsupial

25 Placental Mammals

26 Characteristics of Placentals Placental mammals carry unborn young in the uterus until young can survive in the wild. Oxygen and nutrients are transferred from mother’s blood to baby’s blood

27 Placental Characteristics The placenta is a membrane providing nutrients and waste & gas exchange between the mother and developing young Gestation period-is the time which mammals develop in mother’s uterus
