What are fish scales called?
The placoid scales of cartilaginous fishes are also called dermal denticles and are structurally homologous with vertebrate teeth. Most fish are also covered in a layer of mucus or slime which can protect against pathogens such as bacteria, fungi, and viruses, and reduce surface resistance when the fish swims.
Why are snakes covered with dry scales?
Snakes bodies are covered with scales. Without this protective armor snakes could not move over rough or hot surfaces like tree bark, rocks, and hot desert sand. Rough belly scales allow the snake to keep their grip on rough branches and to push off of surfaces when they need to move.

Do fish scales heal wounds?
