how many bones a shark have?

Sagot :

None! A shark doesn’t have any bones in it’s body.

That doesn’t mean a shark doesn’t have a skeleton however. A shark is classed as a chondrichthyes fish who’s skeletons are very different from those of bony fish and terrestrial vertebrates. Sharks and other cartilaginous fish (including skates and rays) have skeletons made of cartilage and connective tissue.
A shark has no bones. You may wonder if their teeth are bones, but actually they are, but they do not count as bones because they are not inside the body.
