Vertebrates

Burp ah that was a good lunch! Today you are going to learn about vertebrates. Vertebrates are animals that have a backbone. Frogs and other vertebrates have a skeleton that shapes the body and protects body parts. A backbone is an important muscle in your body. I am tired. Do you know that the skeleton is mostly made of bone tissue? But some of the tissue contains cartilage. Cartilage is a firm,flexible, material that covers the ends of most bones! My leg hurts I will teach you more next. Also have you had a frog leg it is good! See you later.
