Stomiidae
Stomiidae is a family of deep-sea ray-finned fish, including the barbeled dragonfishes. They are quite small, usually around 15 cm, up to 26 cm. These fish are apex predators and have enormous jaws filled with fang-like teeth. They are also able to hinge the neurocranium and upper-jaw system, which leads to the opening of the jaw to more than 100 degrees. This ability allows them to consume extremely large prey, often 50% greater than their standard length. Features It is one of the many species of deep-sea fish that can produce their own light through a chemical process known as bioluminescence. A special organ known as a photophore helps produce this light. The deep-sea dragonfishes have large heads, and mouths equipped with many sharp fang-like teeth. They have a long stringlike structure known as barbel, with a light-producing photophore at the tip, attached to their chin. They also have photophores attached along the sides of their body.

Astronesthes Niger
''Astronesthes niger'', commonly known as snaggletooth, is a species of small, deep sea fish in the family Stomiidae. It occurs in the tropical and subtropical Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico, as well as the Indian Ocean and western Pacific Ocean, at depths to . Description ''Astronesthes niger'' is a slender, somewhat elongate, black fish with a large mouth, fang-like teeth, and a long barbel on its chin tipped by a knob. This fish grows to a maximum length of about and can be distinguished from other closely related species by its snout lacking a turned up tip, by the barbel being less than 1.7 times the length of the head, and by the swollen portion on the barbel being one third to one half its length. The dorsal fin has 15 to 17 soft rays and is set slightly behind the pelvic fins. There is a ventral adipose fin in front of the anus, and the anal fin has 12 to 15 soft rays. There are two longitudinal rows of photophores on either flank and there are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aristostomias
''Aristostomias'' is a genus of barbeled dragonfishes native to the ocean depths in the Pacific, Atlantic and Indian oceans. Red Light Bioluminescence Production of red light bioluminescence Similar to other deep-sea organisms that are capable of producing red light bioluminescence, including '' Pachystomias'', ''Aristostomias'' has large suborbital photophores that produce red-shifted cold light. In addition, ''Aristostomias'' has postorbital photophores that emit blue-green light. Visual systems Most meso- and bathypelagic fish are only able to see shortwave light, as their retinae possess rods with rhodopsins sensitive to blue light. ''Aristostomias'' is able to detect red-shifted light, as their retinae have long-wave absorbing rhodopsins and porphyropsins that can detect wavelengths of up to 590 nm. ''Aristostomias'' can detect red light at distances of up to 2 meters, suggesting that detection is used primarily for close-range intraspecific communication and sho ...

Bioluminescence
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus '' Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and so ...

''Chirostomias pliopterus'' is a species of barbeled dragonfish found in the Atlantic Ocean. This species grows to a length of SL. This species is the only described member of its genus.

Compared to other bioluminescent fish, ''Pachystomias'' has a uniquely large suborbital photophore, which extends from the orbit to the roof of the mouth, while the preorbital photophore is much smaller. The suborbital and preorbital organs have been observed to produce both brig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
