Extended data The luminous organ of the lantern fish is specialized by a group of skin gland cells to become luminous cells. This cell can secrete an glandular fluid containing phosphorus, which can be oxidized by oxygen in the blood in the glandular cells, and the fluorescence emitted in the oxidation reaction is the light emitted by the lantern fish.

There are about hundreds of species of lantern fish in the world, and they generally live in the deep sea. Its luminescence is a survival adaptation to the dark deep-sea environment. In the dark deep sea, the light they emit can be used to trap prey, confuse enemies and lure the opposite sex, which is beneficial to group life.
