Lamp Fish

The picture of the lantern fish swimming in a group faces friends who like to wear fish. It must be extremely beautiful to us, but why does this fish glow? Why does the luminescence of lantern fish gradually disappear after being kept for a long time? The editor will tell you the reason why the lantern fish glows.
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, which is the golden lantern. The body surface of the golden lamp has a golden base color, and there are a few small silver freckles on the body. It can be grown artificially. However, I heard that the grown species only have a little gold on the body, and even disappear completely when they grow up, and the whole fish looks a bit like It is 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, because there is no way to provide the water quality in the native place, these luminous bacteria will gradually disappear. This is a quite special situation among lantern fish.
