Vertebrates evolution

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

classify = sort
there are many ways to group living things

you can classify animals into two main groups. vertebrates and in vertebrates.

all vertebrates have have ...

  • covering of skin that protects them
  • skeleton inside their body
  • muscles inside 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 supports their weight
  • some have a hard covering or shell on the outside of their bodies for protection
