What adaptations do dragonfish have?
Summary: The transparent teeth of the deep-sea dragonfish help camouflage the dragonfish from their prey. The unique adaptation results from their teeth having an unusually crystalline nanostructure mixed with amorphous regions.
What do dragon fish do?
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.
What is special about the Black Dragonfish?
Black dragonfish are bioluminescent, but unlike most such predators, which use their light primarily to attract prey, they can see their own light. As a result, the fish can use their light to hunt. The light is nearly in the infrared and barely visible to the human eye.
Are deep-sea dragonfish carnivores?
Despite measuring just 15 centimetres in length, deep-sea dragonfish (Aristostomias scintillans) are apex predators and feed on fish that are up to half their size. They are so voracious that they even eat each other. If their teeth were visible, prey would immediately shy away, researchers say.
How does a dragon fish protect itself?
The Black Dragonfish has only one defense and that would be its bioluminescence in its body. The Red Flounder fish would be found on the ocean floor. The Black Dragonfish’s defense is bioluminescence the bioluminescence is found all over its body starting with the outside and almost to the inside.
How do Dragonfish survive?
Since many of their prey also produce light themselves, the dragonfish has evolved special method of remaining hidden from predators after its meal. The walls of its stomach are black to keep the lights concealed while its meal is digested.
How do Dragonfish glow?
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. The dragonfish has a large head and mouth equipped with many sharp, fang-like teeth.
Can Dragonfish see?
A species of dragon fish, Pachystomias microdon, that can see and emit far red light using organs, called photophores, below its eyes. (Image credit: Edith Widder, Ocean Research & Conservation Assoc.)
How do dragonfish move?
The dragonfish can use its light-producing barbel like a fishing lure. By flashing it on and off and waving it back and forth, it is thought that the dragonfish can attract the attention of its potential meal. Once an unsuspecting fish gets too close, it is snapped up in the dragonfish’s powerful jaws.

How do dragonfish use bioluminescence?
This protrusion is referred to as a barbel, which is tipped with a specialized photophore organ that is responsible for generating light. Through a process known as bioluminescence, dragonfish generate a flashing light used to attract and disorient prey as well as signal to potential mates.
How long can a dragon fish live?
about 10 years
Dragonfishes are small and can be about 6.5 to 15 inches long only. How long does a dragonfish live? Though there are many different species, a dragonfish can live about 10 years with the right environment while in captivity.
How does dragon fish produce light?
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.
How does the Black Dragonfish glow?
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.
