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 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 that moves through tubes
*Lungs or 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, spiders, crabs snails, clams.
