What covers a tiger shark?

A tiger shark is covered in skin. Like most sharks, it has tough, sandpaper-like skin called dermal denticles. These are tiny, tooth-like scales that help the shark streamline its body for swimming and protect it from injury.

Here's a breakdown:

* Skin: The outer layer of the shark's body.

* Dermal denticles: Tiny, tooth-like scales embedded in the skin. They are made of dentine and enamel, just like teeth.

* Coloration: Tiger sharks are typically grayish-brown with dark stripes, giving them their name.
