Evolution Vertebrate

In room 6 we have been learning to classify animals. Scientists classify animals and plants into groups in order to make them easier to identify, sort, and name them.

Clasify= SORT 

There are many different ways to group living things.

You can classify animals into two main groups vertebrate or invertibrate.

All vertebrates have:

• Covering of skin that protects them
• Skeleton inside their body
• Muscles that help them move
• Blood that moves through tubes 
• Lungs or gills for breathing
  

All 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 supports their weight
• Some have a hard covering or shell on the outside  of their bodies for protection-Insects, Spiders, crabs, Snails, clams.
