Vertebrates

Vertebrates have backbones and brain cases. There is a lot of different kinds of vertebrates. To be exact there is 40,000 different kinds of vertebrates. There are eight different classes of vertebrates. Some of them are fish, mammals, lampreys, amphibians, reptiles, and birds. Vertebrates have spines. Sharks have cartilage and that is like tissue that is waxy. Vertebrates usually have necks. Some don't. They also have chests.  I like vertebrates cause I am one! Also they are cool cause i like dolphins. I also kinda like sharks. That is what I learned about vertebrates. Well that is all!            BYE!!!!!!!!!
