Why sharks dont have bones?

Our bodies need the unbending strength of bone to support their weight on land. In the water, however, sharks’ cartilaginous skeletons have helped them survive and thrive.

Are sharks endoskeleton or exoskeleton?

Cartilaginous skeleton Unlike fishes with bony skeletons, a shark’s skeleton is made out of cartilage. This is a flexible but strong connective tissue that’s also found throughout the human body, in places like the nose, ears, and in joints between bones.
