1. The Animal Kingdom
Living on Planet Earth

2. Animal Kingdom
All members of the kingdom of animals have one thing in common—they have a mouth or similar structure used to ingest food. If not, then they absorb their food and they belong to another kingdom of living creatures.

3. Animal Kingdom
Think of a shirt soaking up water. If a life form absorbs nutrients through its cells it’s not an animal.
It is from another kingdom of life forms.

4. Animal Kingdom
The Animal Kingdom is divided into groups of animals that have the same body or genetic plan.
Let’s learn about the different kinds of animals.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates

5. Animal Kingdom
We’ll explain what makes some animals the same, and point out some differences.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates

6. Animal Kingdom
Animals are sorted into classes that include: mammals, birds, amphibians, fish, reptiles and invertebrates.
Today we’ll learn how to sort animals into each group.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates

7. Animal Kingdom
Some animals have bones or cartilage inside that give them shape and help them to move.
If you remove all the fleshy parts of the animal you will have a skeleton.

8. Animal Kingdom
Animals that have bones or cartilage are called vertebrates.
These bones protect the spinal cord which carries the sensory information from all parts of the body to the brain.
Your vertebrae allow you to bend and to turn.

9. Animal Kingdom Nod your head up and down meaning “YES”.
That’s right!
Nod your head up and down meaning “YES”.
Yes, you are a vertebrate animal.

10. Animal Kingdom Five of the six animal classes are vertebrates.
They are: mammals, birds, amphibians, fish and reptiles.
Mammals
Birds
Amphibians
Reptiles
Fish

11. Animal Kingdom
Invertebrates do not have bones.

12. Animal Kingdom
Many invertebrates have a hard outside called an exoskeleton.

13. Animal Kingdom
It seems silly that mammals, birds, amphibians, fish and reptiles all have vertebrae inside them and the one animal group that has no bones inside is called an invertebrate!
Well that’s because the very old Latin language used the prefix “in” meaning: not, without or opposite of; and the classes of the Animal Kingdom were named a long time ago.

14. Animal Kingdom
Another major difference in animal classification is how the animals maintain their body temperature.
Warm-blooded animals are mammals and birds.
Cold-blooded animals are amphibians, fish, reptiles and invertebrates.

15. Animal Kingdom
Mammals and birds regulate their temperature internally.
They convert food to heat.
They keep cool by drinking water and sweating it out of their bodies.

16. Animal Kingdom
What food and water isn’t used to keep their body temperature normal is used for growth and maintenance.
This process is called warm-bloodedness.
Mammals
Birds

17. Animal Kingdom
Cold-blooded animals include amphibians, fish, reptiles and invertebrates.
These animals rely on the warmth of the sun and their surroundings to control their temperature.
Amphibians
Reptiles
Fish
Invertebrates

18. Animal Kingdom
Cold-blooded animals don’t depend upon food to keep them warm just to help them grow and maintain life.

Animal Kingdom
Water and air temperature play an important part in keeping cold-blooded animals comfortable.
No sweat!
I’m just keeping my mouth open to stay cool.

20. Animal Kingdom Let’s look at each class of animals more closely.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates

21. Animal Kingdom Mammals
Have mouths to ingest food
Have vertebrae to support their bodies
Are warm-blooded
Breathe with lungs
Nourish their young with milk
Have skin with hair or hair follicles

22. Animal Kingdom Birds Have mouths to ingest food
Have vertebrae to support their bodies
Are warm-blooded
Breathe with lungs
Have a beak made of bone
Have wings
Have skin covered in feathers

23. Animal Kingdom Amphibians
Have mouths to ingest food
Have vertebrae to support their bodies
Are cold-blooded
The baby, or larvae forms, live in water and breathe with gills. Most will develop lungs as an adult and can live on land.
Have permeable skin that water and oxygen move through

24. Animal Kingdom Fish Have mouths to ingest food
Have vertebrae to support their bodies
Are cold-blooded
Breathe with gills
Have skin with scales or plates

25. Animal Kingdom Reptiles
Have mouths to ingest food
Have vertebrae to support their bodies
Are cold-blooded
Breathe with lungs
Have skin with scales or plates

26. Animal Kingdom Invertebrates
Have mouths or other methods of ingesting food at some stage of their lives
Have no backbone or spinal column to support their bodies
Are cold-blooded
Breathe with gills or pores

27. Animal Kingdom Invertebrates
This group has the most numerous species and variations of life support. Invertebrates can be found almost anywhere on Earth.

28. Animal Kingdom
Some animals are so small you need a microscope to see them.
Each class has animals that lay eggs. Not all animals lay eggs.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates

29. Animal Kingdom
Look for animals on the land, in the water and in the air.
You’ll be surprised to learn where the members of each class can be found.
Mammals
Birds
Amphibians
Reptiles
Fish
Invertebrates
