Shark skin is not soft and smooth as they it is covered in specialized scales. These scales are called placoid scales or dermal denticles.
Sharks don't have scales. They have skin. Actually they have a kind of teeth on their skin called denticles.
Dermal denticles. Literally, "skin teeth." They are similar in structure to the teeth of a shark. See http://en.wikipedia.org/wiki/Dermal_denticle
actually, sharks have denticles. denticles are very different from fish scales because they are constructed like hard, sharp teeth to help prevent any injury to the shark's body.
Shark skin looks and feels like it is covered with tiny teeth. In fact, their small, rough placoid scales (also called denticles), have the same structure as sharks' teeth! Shark skin is sometimes used as sandpaper.www.vanaqua.org/education/aquafacts/sharks.html

No. they are covered in rough skin called denticles.
Sharks are fish so, like all fish, they have scales. In the case of sharks, these scales are somewhat different in composition, and actually make up a yep of skin. Shark skin is made up of tiny, hard, tooth-like structures known as dermal denticles or placoid scales.

They have special scales like many sharks called placoid scales
A hammerhead's body covering is scales and skin.
Amphibians do not have hard scales. Their skin is smooth. It is covered in a thin layer of mucus to keep it moist.
