Conditions of Use
Dear Mr. McCartney,
I learned vertebrate means “backbone”. All vertebrates have backbones and invertebrates don’t have a backbone. Some vertebrates are mammals, birds, reptiles, and amphibians.
We also learned about 3 types of fish: cartilaginous, bony, and jawless. Cartilaginous fish has a body structure made of cartilage. Bony fish has a skeleton made of bones.
The jawless fish are fish without a jaw.
I ended up liking the whole project. It was good working on the project with partners.
