You mean you don't know?
Why are you doing her homework for her?
She should be searching this herself, not having you cheat for her on Yahoo Answers.

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.

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

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.
