Bats are mamals.

They all have back bones but they may not all be bone some may be caralige. All you had to do is search. Actually all your child had to do was search. You'll find 2/3rds of you answer at the link below.

type in a search for "vertebrae" on wikipedia www.wikipedia.org

sharks don't have a backbone--their entire body is made of cartilage. fish do have a backbone, and i'm sure bats do too.

Absolutly all 3 have backbones.

Bats, fish and sharks are all vetebrates! (meaning they all have backbones) If you have other questions like this, put it in the zoology category and you'll have many science majors willing to help.

they ALL have backbones - although the sharks entire system is made of cartilage, it is still classed as a back bone - if not it would be an "invertibrate"

sharks ARE fish

Bats and fish have backbones. If your daughter's class wants a technical answer, then sharks do not. Sharks have no bony tissue and are instead cartilaginous.

"Cartilage is the only component of the skeletons of certain primitive vertebrates, including lampreys and sharks. It is composed of a dense network of collagen fibres embedded in a firm, gelatinous ground substance that has the consistency of plastic; this structure gives the tissue tensile strength, enabling it to bear weight while retaining greater flexibility than bone." -Britannica.com

Then again if you listen to Redawg, the first responder, then the above is an uneducated misinformed answer. Opps.
