Vertebrates

 In room 6 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 organisms.

You can classify animals into two main groups. Vertebrate 

or Invertebrate. 

All vertebrates have...

.Covering of skin that protects them

. Skeleton inside their body

. Muscles that help them move

. Blood moves through tubes

. Lungs or gills for breathing

Invertebrates

.90%  of animals are invertebrates

. Tend to be small because they do not have a backbone.

. Many live in the ocean because the water supports their weight

. Some have a hard covering or a shell on the outside of their bodys

for protection
