1. Classification

2. Essential Question How are animals classified? Vocabulary to know:
Classification
Vertebrate
Invertebrate

3. Classification?
Animals are separated into groups or categories so that they are more easily studied and discussed by scientists and others.

4. Two Main Animal Groups
The two main groups of animals are vertebrates and invertebrates.

5. Invertebrates
They tend to be small because they do not have a backbone to support their bodies. Many invertebrates live in the ocean, where the water helps support their weight.

6. What other things are invertebrates?
Worms
Snails
Sponges
Crabs
Lobster
Shrimp
Clams
Cockroaches
Spiders

7. Vertebrates
They are animals that have backbones, such as a tiger or you! They can be as different as frogs and elephants. This large group of animals is divided into five smaller groups. Vertebrates tend to be much bigger than invertebrates.

8. The 5 groups of vertebrates

9. Animal Classification
Mammals
Fish
Birds
Reptiles
Amphibians

10. Mammals Characteristics: Have teeth Have hair Are warm blooded
Have a single jaw bone
Have inner ear bones
Produce milk for their young

11. Mammals
Mammals have larger brains and seem to be the most capable  learners. 
All mammalian mothers nourish  their babies with milk.

12. Fish Characteristics: Are cold-blooded vertebrate (backbone)
Live in water
Usually have paired fins, gills, and scales

13. Fish Most fish lay large numbers of eggs, but some have live birth.
Most fish breathe by drawing water over four or five pairs of gills.

14. Amphibians Characteristics: Are cold-blooded vertebrate (backbone)
Lay their eggs in water
Lack any skin coverings such as fur, scales or feathers

15. Amphibians Young amphibians tend to resemble small fish.
Amphibian means "two lives," a  reference to the change that frogs go through as they move from egg to  tadpole to frog. 
Even as adults, most frogs and other amphibians must stay close to water. 

16. Birds Characteristics: Have feathers Lay eggs
Have bodies specially adapted for flight
Have a beak rather than teeth

17. Birds Their nearly hollow bones provide lightweight strength.
Birds now live almost everywhere on Earth.

18. Reptiles Characteristics: Have scales Lay leathery eggs on land
Are often called cold-blooded because they can't regulate their own body temperature

19. Reptiles Reptiles do not use energy to fuel internal "furnaces"
Although reptiles breathe through lungs, some reptiles can also absorb oxygen in water through their mouth.
