| Fish
belong in the group of animals called vertebrates. This
means they have a backbone and an internal skeleton made
of bone or cartilage. They breathe under water through
their gills, and move around using fins. Fish are
cold-blooded animals, meaning their bodies are the same
temperature as the water around them.
