Lantern fish
We Seeing lantern fish swimming in schools is a very beautiful sight, so why do these mysterious little objects glow? What special materials do they have that can emit light?
The reason why the lantern fish glows is the precipitation of pigment, which is technically called "guanopurine crystals". These crystals accumulate in the dermis of the lantern fish and are refracted by the light, so the lantern fish often looks bright. Bright, and viewed from different angles, there will be slight changes due to different light reflections.
There is also a theory that it is reflection caused by parasitic bacteria on the surface. This situation is more common in deep-sea fish. This should not be the case for lantern fish. However, in actual situations, there is a very special example, that is The Golden Lamp has a golden base color and a little silvery freckles on its body. It can be grown artificially. However, it is said that the grown species only have a little gold on their body, and even completely disappear when they grow up. The whole fish It's a bit like a transparent pattern, so some scholars believe that the "gold" on the golden lantern is attached to the so-called luminescent bacteria, which is not the same as the reason why ordinary lantern fish glow comes from "guanopurine crystals" under the skin. . In an artificially raised environment, there is no way to provide the water quality in the native place, so these luminous bacteria will gradually disappear. This is a very special situation among lantern fish.
