It is believed that they are external spawners, meaning that the female releases eggs into the water to be fertilized by the male. The eggs then float to the surface where they remain until hatching.
How do Dragonfish produce bioluminescence?
It turns out that they use specialized light-emitting cells, known as photophores, which are located below their eyes. These cells create bioluminescence in very much the same way as other deep-sea creatures, by using an enzyme called coelenterazine which emits photons when introduced to free radicals.

What is a deep sea dragonfish?
The deep-sea dragonfish (Stomiidae ), also called the barbeled dragonfish, uses it’s fang-like teeth to grab prey in its deep-sea environment. Like other deep-sea organisms, dragonfish have bioluminescent photophores and other adaptations that allow them to make do at extreme depths.

Dragonfish teeth are made from an outer enamel-like layer and an inner layer made of dentin. But the evolution of transparent teeth means that this bioluminescence doesn’t reflect onto their teeth and blow their cover. This means the mouth would be invisible to prey right until the moment it was caught.

How do dragonfish light up in the dark?
The deep sea dragonfish is one of the many species of deep sea fish that can produce its own light through a chemical process known as bioluminescence. The light is produced by a special organ known as a photophore. It is believed that the fish can use these flashing lights in the dark waters to attract prey and even to signal potential mates.
