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.
