Introduction to Mammals Endotherms Hair or Fur Feed Young with Milk
Phylogeny Separated into three groups Prototheria (before gestation) – egg laying mammals Metatheria (middle gestation) – pouched mammals Eutheria (true gestation) – live birth from uterus
Milk Produced in mammary glands May have been sweat glands Feed young, increase success
Types of teeth Incisors – cutting Canines – can be enlarged, piercing Carnassal – shearing, remove meat from bones Molars - grinding
Cardiovascular System Body temperature is internally regulated (endothermic) Heart is 4-chambered High metabolism Heart rate – depends on size of animal (smaller = faster rate)
Excretory System Urinary bladder – need more water per day Advanced kidneys – filter more blood
Reproductive System Dioecious Highly variable in shape Placental mammals Nonplacental mammals
Digestive System Length differs based on diet –Predators short –Herbivores very long –Omnivores medium length
MAMMALS. MAMMALS Mammals (formally Mammalia) are a class of vertebrate, air- breathing animals whose females are characterized by the possession of mammary.
