What Is Fish Skin Made of?

The fish skin is made of two distinct layers, viz and outermost layer, the epidermis and inner layer dermis. 

The skin is the outermost covering or wrapping of the body, so it is the most exposed part of the body to the environment. The skin plays an important role as the first line of defense. 

In most fish, the skin is well adapted for protection from injury and disease. It functions also for respiration, excretion, and osmoregulation. 

The epidermis layer of fish skin is composed of many layers of flattened and moist epithelial cells. The innermost layer is called stratum germinativum made up of active columnar cells and continuously divided by mitotic division. 

The epithelium of the epidermis consists of a variety of glands, which are:

  • Mucous glands : secrete slippery mucus which contain lipoprotein
  • Poison glands : secrete poisonous substances to protect themselves from the enemy for defense.
  • Photophores : produce light, mostly found in deep-sea fishes.

Moreover, the dermis layer lay down beneath the epidermis and contains blood vessels, nerves, connective tissues, and sense organs. 

This layer is well supplied by blood vessels, therefore it also provides nourishment to the epidermis. If you want to know more details about the structure of fish skin, please click here
