Answer:

Shark skin is like a sandpaper which plays a significant role in the dynamic shark movements. Internally, this skin has millions of tiny scales which have the form of teeth called “dental dermicles” which create a thick mesh with a protein called collagen.

The skin covers muscles and has them attached in a way that creates an armor which acts in a similar way to an external skeleton, although it is not an exoskeleton.
