A fish scale is a tiny, hard plate that emerges from the fish's epidermis.
These protective scales, which are also good camouflage due to reflection and coloration as well as potential hydrodynamic benefits, cover the skin of the majority of jawed fishes.
As long as the fish has been washed and taken care of correctly before eating, fish skin is safe to consume.
We can reduce the exposure to potentially dangerous substances by eating fish with skin that is lower in mercury and other pollutants.
If properly cooked and completely cleaned, fish scales are edible.
Collagen, a fibrous protein that may be healthy, is also known to be present in fish scales.
