  • Click on a lesson name to select. Mammals Section 1: Mammalian Characteristics Section 2: Diversity of Mammals
  • Slide 4
  • Hair and Mammary Glands Two characteristics that distinguish members of class Mammalia from other vertebrate animals are hair and mammary glands. Mammalian Characteristics Mammals Section 1
  • Slide 5
  • Mammals Section 1
  • Slide 6
  • Functions of Hair 1. Insulation Mammals 2. Camouflage 3. Sensory devices 4. Waterproofing 5. Signaling 6. Defense Mammalian Characteristics Section 1
  • Slide 7
  • Other Characteristics Endothermy Mammals Source of body heat is internal. Heat is produced by a high metabolic rate. Body temperature is regulated by internal feedback mechanisms. Mammalian Characteristics Section 1
  • Slide 8
  • Feeding and Digestion Daily intake of food is used to generate heat to maintain a constant body temperature. Mammals Mammalian Characteristics Section 1
  • Slide 9
  • Mammals Mammalian Characteristics Section 1
  • Slide 10
  • Mammals Section 1
  • Slide 11
  • Trophic Categories 1. Insectivores Mammals 2. Herbivores 3. Carnivores 4. Omnivores Mammalian Characteristics Section 1
  • Slide 12
  • Teeth Reveal the life habits of a mammal Mammals Carnivores use canines to stab and premolars to slice and shear meat. Incisors of insectivores are long and curved, functioning as pincers in seizing insect prey. Mammalian Characteristics Section 1
  • Slide 13
  • Excretion Kidneys excrete or retain the proper amount of water in body fluids. Mammals Enables mammals to live in extreme environments Mammalian Characteristics Section 1 Mammals
  • Slide 14
  • Respiration High levels of oxygen are required to maintain a high level of metabolism. Mammals Mammals are the only animals that have a diaphragm. Mammalian Characteristics Section 1
  • Slide 15
  • Circulation Mammals require a consistent supply of nutrients and oxygen to maintain homeostasis. Mammals Keeping oxygenated and deoxygenated blood separate makes the delivery of nutrients and oxygen more efficient. Mammalian Characteristics Section 1
  • Slide 16
  • The Brain and Senses Mammals have highly developed brains. Mammals Cerebral cortex is responsible for coordinating conscious activities, memory, and the ability to learn. Cerebellum is responsible for balance and coordinating movement. Mammalian Characteristics Section 1
  • Slide 17
  • Complex Behavior Senses Mammals The importance of the senses varies from one group of mammals to the next. Glands A system of glands secretes a variety of fluids that helps to regulate a mammals internal environment. Mammalian Characteristics Section 1
  • Slide 18
  • Reproduction In mammals, the egg is fertilized internally. Mammals Development of the embryo takes place in the female uterus. Movement Mammals must find food, shelter, and escape from predators. Mammalian Characteristics Section 1
  • Slide 19
  • Mammal Classification Monotremes Diversity of Mammals Mammals Marsupials Placental mammals Section 2
  • Slide 20
  • Mammals Monotremes Reproduce by laying eggs Duck-billed platypus Echidna Diversity of Mammals Section 2
  • Slide 21
  • Marsupials Very short period of development in the uterus Mammals Crawl into a pouch made of skin and hair and continue development while being nourished by milk from the mothers mammary glands Diversity of Mammals Section 2
  • Slide 22
  • Placental Mammals Give birth to young that do not need further development within a pouch Mammals Represented by 18 orders Diversity of Mammals Section 2
  • Slide 23
  • Mammals Diversity of Mammals Section 2
  • Slide 24
  • Mammals Section 2 Table 30.2 Order of Placental Mammals
  • Slide 25
  • Evolution of Mammals Mammals Diversity of Mammals Section 2
  • Slide 26
  • Therapsids A therapsid is an extinct vertebrate with both mammalian and reptilian features. Mammals Pair of holes in the roof of the skull that allowed for the attachment of jaw muscles Limbs positioned beneath their bodies Might have been endotherms Diversity of Mammals Section 2
