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. What Makes a Mammal? 5 Things All Mammals Have in Common: –All breathe air –All have 4-chambered heart –All are endotherms (warm-blooded) –All.
Animals 4-1 Bird- endothermic, vertebrate, that has feathers, a four-chambered heart, lays eggs, and has scales on their legs and feet. Notes.
Bird An endothermic vertebrate that has feathers, a four chambered heart and lays eggs Contour Feather A large feather that helps give shape to a bird’s.
Mammals Learning Target Objectives: Distinguish between different groups of mammals, listing examples of each. Compare and contrast features of organisms.

MAMMALS. MAMMALS Mammals (formally Mammalia) are a class of vertebrate, air- breathing animals whose females are characterized by the possession of mammary.
Characteristics of Mammals Mammals are endothermic vertebrates that have hair and produce milk to feed their young. Mammals can be found almost everywhere.
Mammals… It’s A Fact! Most have hair or fur Vertebrates – backbone Most babies are born alive Have two pairs of limbs Warm-blooded Young feed.

Characteristics of Mammals By Noelle Thrash. Mammals have hair mammals are the only animals that have hair or fur. Mammalian fur is made out of keratin.

All About Mammals What is a mammal? A mammal is an animal that has hair or fur. What mammal does this fur belong to? Most mammals give birth to live.
Open note quiz: amphibians & reptiles
Mammals Have hair Ability to nourish their young with milk Breathe air 4-chambered heart Endotherms.
By Kelsey Hamilton. Mammals are the only living organisms to have hair or fur. This helps to keep the mammal warm. All mammals have four-chambered.
Phylum Chordata. Includes 5 Classes 1.Fish 2.Amphibians 3.Reptiles 4.Birds 5.Mammals.
Mammals are warm-blooded. Warm-blooded means to be able to change their body temperature by their selves. They are also vertebrates. Vertebrate.
