Evolution vertebrates



In room six we have been learning to classify animals. scientists classify animals and plants into groups in order to easily identify, sort, and name them.

Classify = SORT
There are many different ways to group living things.

Classifying Animals
You can classify animals into two main groups. vertebrates or invertebrates 

ALL vertebrates have..
*Covering skin that protects them. 
* skeleton inside their body.
*Muscles that help them move.
*Blood moves through tubes.
* Lungs and gills for breathing.

Invertebrates 
* 90% of all animals are invertebrates. 
* Tend to be small because they do not have a backbone.
* Many live in the ocean because the water helps support their weight.
* Some have a hard covering or shell on the outside of their bodies for protection.
- Insects, spider, crabs, snails, clams
