In most such fishes, luminescence is produced intracellularly; the light is emitted by special cells called photocytes. silhouette that a fish throws to predators beneath it in the water Our editors will review what you’ve submitted and determine whether to revise the article.Deep-sea hatchetfishes are small, shining silver fishes.
Its name suggests it may be based on the neon tetra.
Deep-bodied and flattened from side to side, they have slender tails and rows of light organs along the lower edge of each side of the body.
This article was most recently revised and updated by Deep-sea fishes… Bioluminescence is the result of chemical processes, where the energy produced is released as visible light. There are about 40 species ranging between 3 and 12 centimetres in length and they obviously get their name from their hatchet shape when seen in profile.
At day break, they return to the blackness of the deep ocean.
They are most well known for their extremely thin bodies which really do resemble the blade of a hatchet. These photophores produce light by means of a chemical reaction similar to that of the land-based firefly. Hatchetfishes are found in most temperate waters of the world where they are found at depths ranging from 600 feet (180 meters) to 4,500 feet (1,370 meters).To search this site, type your search word(s) in theAll content on this site is Copyright © 1998 - 2016 by Sea and Sky.

Most bioluminescent organisms are found in the ocean.
You probably won't have these guys in your aquarium at home, although you might have the unrelated Freshwater Hatchetfish instead. and squid have developed bioluminescent 'counterillumination' abilities. Hatchetfishes have large, tubular eyes that pointing upward. In most such fishes, luminescence is produced intracellularly; the light is emitted by special cells called photocytes.

This use of bioluminescent light is called "counterillumination," a common adaptation in midwater fishes and cephalopods.
Most researchers agree that they have a short life span of no longer than a year. They are small deep-sea fishes which have evolved a peculiar body shape and like their relatives have bioluminescent photophores.

In doing so, they're counterilluminating their bodies in a clever camouflage technique.
Hatchetfish can regulate the intensity and color of light from these organs to match the light filtering down.
Some species, including the giant hatchetfish can be brown or dark green in color.
Hatchetfish can actually shift the intensity of their bioluminescence based on the light available from above to optimize camouflage. The patterns of light created by the photophores differs slightly from one species to another, leading many researchers to believe that they may play a role in courtship, although very little is know about the mating habits of these mysterious creatures. Light-emitting organs called photophores line their undersides.
This giant of the family grows to an impressive six inches (12 centimeters) in length. Some midwater predators hunt by looking up for the silhouettes of animals. Most of the smaller hatchetfish species are covered in delicate silvery scales.
The ecological importance of bioluminescence in the ocean is manifest in the dominance of light emitters in open waters; luminescent fish (e.g., mycophids and hatchetfish) and crustaceans (e.g., copepods, krill, and decapods) dominate in terms of biomass, whereas bacteria and dinoflagellates dominate in terms of abundance. Accordingly, many fish, crustaceans
Accordingly, many fish, crustaceans and squid have developed bioluminescent 'counterillumination' abilities. AskNature Team September 14, 2016. This means that they can adjust the intensity of their underside lights to make them nearly invisible against the faint light above.

This enables them to search for food falling from the above. History at your fingertips These fish have special light-producing organs known as photophores that run along the length of their body.
