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.

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.
![Page 4: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/4.jpg)
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.

Types of Monotremes There are three
species of monotremes:
The duck-billed platypus and two spiny anteaters.

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.

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.

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 mother’s uterus and it delivers oxygen and nutrients to the young.
Most mammals are placental mammals.
![Page 9: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/9.jpg)
Types of Placental Mammals There are almost
4,000 known species of placental mammals.
The most common: people, cats, dogs, and horses.

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).
![Page 11: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/11.jpg)
The Different Types of Diets There are four types of diets that mammals
can have. They can be: Herbivores Carnivores Omnivores Insectivores
![Page 12: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/12.jpg)
Herbivores Herbivores are plant
eaters. Some herbivores
include: beavers, cows, horses, pandas, sloths, and others.
Pictured are panda bears.

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

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

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

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.
![Page 18: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/18.jpg)
The Fastest Mammal The fastest mammal
(also the fastest land animal) it the Cheetah.
The cheetah runs between 60 and 70 miles per hour.
![Page 19: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/19.jpg)
The Slowest Mammal The slowest mammal
is the sloth. The sloth moves less
than 1 mile per hour.

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.

The Tallest Mammal The tallest
mammal is the giraffe.

The Smallest Mammals 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.

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

The Smelliest Mammal The smelliest
mammal is the striped skunk.

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

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.
![Page 27: Mammals presentation](https://reader031.fdocuments.net/reader031/viewer/2022020116/55aa17241a28ab42248b45ec/html5/thumbnails/27.jpg)
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?
