Versatile Vertebrates

Versatile Vertebrates. Sounds like a magic formula, right? But don't be confused. It's a scientific term for a specific group of species. Including us. Among vertebrates belong: cyclostomi aka round mouths, cartilaginous fishes, fishes, amphibians, reptiles, birds and mammals. What do they have in common? What is typical for their body? Are you shaking your head in confusion, telling yourself that you don't know? Shaking your head is a sign that you are a vertebrate! Because backbone and cranium are typical for them. Actually, for us.
