What Is A Mammal?

• Mammals are animals that have hair, are
  warm-blooded, and nourish their young with milk.
• Some modern-day mammals include people, apes,
  dogs, mice, elephants, pandas, and many more.

3
Types Of Mammals

• Monotremes are primitive egg-laying mammals.
• Marsupials their young are born in an extremely
  immature state.
• Placental mammals their young are born at an
  advanced state.

4
Monotremes

• Monotremes are the most primitive mammals. These
  mammals lay eggs, after the babies hatch, the
  mothers nourish their young with milk. Today,
  monotremes only live in Australia and New Guinea.

5
Types of Monotremes

• There are three species of monotremes
• The duck-billed platypus and two spiny anteaters.
• This is a picture of a duck-billed platypus

6
Marsupials

• Marsupials are pouched mammals whose babies are
  born in a very undeveloped state. The young
  attach themselves to their mother. Many
  marsupials have a pouch that encloses the young.
• Marsupials evolved about 100 to 75 million years
  ago, during the time of the dinosaurs.

7
Types of Marsupials

• The biggest is the human sized red kangaroo.
• The smallest is the pilbara, it would fit in a
  persons hand.
• Kangaroo, opossum, Tasmanian devil, and koala the
  most common.
• The only marsupial in North America is the
  Virginia opossum.
• Pictured is a kangaroo.

8
Placental Mammals

• Placental mammals are advanced mammals whose
  young are born at an advanced stage.
• Before birth the young are nourished through a
  placenta. The placenta is attached to the
  mothers uterus and it delivers oxygen and
  nutrients to the young.
• Most mammals are placental mammals.

9
Types of Placental Mammals

• There are almost 4,000 known species of placental
  mammals.
• The most common people, cats, dogs, and horses.

10
Mammal Diets

• Mammals have to eat a lot to maintain their high
  body temperature. Diets vary from mammal to
  mammal. As with most animal groups, there are
  more herbivores (plant-eaters) than there are
  carnivores (meat-eaters).

11
The Different Types of Diets

• There are four types of diets that mammals can
  have. They can be
• Herbivores
• Carnivores
• Omnivores
• Insectivores

12
Herbivores

• Herbivores are plant eaters.
• Some herbivores include beavers, cows, horses,
  pandas, sloths, and others.
• Pictured are panda bears.

13
Carnivores
Baby Dolphin

• Carnivores are meat eaters.
• Some carnivores include whales and dolphins,
  dogs, tigers, lions, and others.

14
Omnivores
Grizzly Bear

• Omnivores eat both plants and meat.
• Some omnivores include people, some bears, and
  others.

15
Insectivores
Aardvark

• Insectivores eat insects.
• Some insectivores include aardvarks, anteaters,
  and others.

16
Venomous Mammals

• Only a few mammals are venomous.
• These mammals include male duckbilled platypus,
  several species of shrews, and the Solenodon (a
  small insectivore).

Mammal Extremes

• Here are some fun mammal facts.
• We are going find out what the fastest, slowest
  and biggest mammals are.
• We will also learn what the smallest, loudest and
  smelliest mammals are.
• Along with some other cool facts.

18
The Fastest Mammal

• The fastest mammal (also the fastest land animal)
  it the Cheetah.
• The cheetah runs between 60 and 70 miles per hour.

19
The Slowest Mammal

• The slowest mammal is the sloth.
• The sloth moves less than 1 mile per hour.

20
The Biggest Mammal

• The biggest mammal also known as the biggest
  animal that ever lived on Earth is the blue
  whale.
• The biggest land mammal is the African Elephant.

21
The Tallest Mammal

• The tallest mammal is the giraffe.

22
The Smallest Mammals
Pygmy Shrew

• The smallest mammal is the pygmy shrew and the
  bumblebee bat.
• The pygmy shrew weighs between 1.2 and 2.7 grams.
• The bumblebee bat weighs about 2 grams.

23
The Loudest Mammal

• The loudest mammal is the blue whale.
• The second loudest is the howler monkey.
• Pictured is a Black Howler Monkey.

24
The Smelliest Mammal

• The smelliest mammal is the striped skunk.

25
The Fattest Mammal
Ringed Seal Pup

• The blue whale has the thickest layer of blubber,
  but the ringed seal pups have the greatest
  percentage of fat (about 50).

26
More Mammal Facts

• There are about 5,000 species of living mammals
• You have learned that mammals are divided into
  three subclasses Monotremes, Marsupials, and
  Placental mammals.
• Mammals unlike other animals have body hair,
  three middle ear bones, and nourish their young
  with milk that females produce.

27
What Did You Learn?

• Hopefully you have learned a lot more about
  mammal.
• I also hope that you found the facts interesting,
  like the biggest and smelliest mammal.
• Do you now know what creature in the picture is
  not a mammal?
