Barbeled Dragonfish
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.

Pegasidae
The seamoths make up a family of fishes, the Pegasidae, within the order Syngnathiformes. They are named for Pegasus, a creature from Greek mythology. Seamoths are notable for their unusual appearance, including flattened bodies, the presence of large, wing-like, pectoral fins, a long snout, and a body encased in thick, bony plates. They are found primarily in coastal tropical waters of the Indo-Pacific. Biology Seamoths have modified pelvic fins that allow them to "walk" across the sea bottom where they live. Their jaws are ventral, located behind their long rostrum, and are toothless. Their mouth is highly specialized, and can form a tube-like mouth used to suck worms and other small invertebrates from their burrows. They periodically molt their skin, perhaps as often as every five days.Herold D, and Clark E. 1993. Monogamy, spawning, and skin-shedding of the seamoth, ''Eurypegasus draconis'' (Pisces: Pegasidae).

Violet Goby
The violet goby (''Gobioides broussonnetii'') is a species of goby native to marine, fresh and brackish waters near the Atlantic coast of North and South America from South Carolina in the United States of America, to northern Brazil. It prefers bays, estuaries and river mouths with muddy substrates. It is often marketed as the dragon goby or dragon fish. Description The violet goby has a long, slender, eel-like body. Its dorsal and anal fins run almost the entire length of the body. The teeth are very sharp; however these are used for scraping algae off rocks, not fighting. When kept in good condition, dragon gobies develop an attractive, iridescent, silvery-blue metallic color with a gold blotch pattern. Violet gobies seen in pet stores are generally long. In the wild, violet gobies can grow to long. However, in captivity they seldom grow past . Males tend to have long, pointed genital papilla, while that of the females are shorter, blunt, and yellow in color. Habita ...

Polypterus Senegalus
''Polypterus senegalus'', the Senegal bichir, gray bichir or Cuvier's bichir, and sometimes called the "dinosaur eel" (a misnomer, as the creature is neither an eel nor a dinosaur), "dinosaur bichir", or "dragon fish" is in the pet trade due to its lungfish-like appearance, which was described as more primitive and prehistoric than other modern fishes. It is a prototypical species of fish in the genus ''Polypterus'', meaning most of its features are held across the genus. It is commonly kept in captivity by hobbyists. They are native from Africa where they are the most widespread species of the genus. Appearance ''Polypterus senegalus'' is an elongated fish, usually grey or beige in color, though it sometimes has shades of white, pink or blue on some of its rhomboid-shaped, multilayer scales. Most of the fish is covered in very subtle patterns with occasional darker blotches or dots. At the nose, the face is smooth and rounded, with larger scales than the rest of the fish. Exte ...

Asian Arowana
The Asian arowana (''Scleropages formosus'') comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. While most consider the different varieties to belong to a single species, work by Pouyaud ''et al.'' (2003) differentiates these varieties into multiple species. They have several other common names, including Asian bonytongue, dragonfish, and a number of names specific to the different color varieties. Native to Southeast Asia, Asian arowanas inhabit blackwater rivers, slow-moving waters flowing through forested swamps and wetlands. Adults feed on other fish, while juveniles feed on insects. These popular aquarium fish have special cultural significance in areas influenced by Chinese culture. The name 'dragonfish' stems from their resemblance to the Chinese dragon. This popularity has had both positive and negative effects on their status as endangered species. Evolution and taxonomy Like all members of the Osteoglossidae, As ...

Draconichthys
''Draconichthys elegans'' (meaning "elegant dragon fish") a selenosteid arthrodire placoderm from the Late Frasnian Kellwasserkalk facies of the Anti-Atlas Mountains of what is now Morocco. During the Late Devonian, the region would have been a shallow, algae-dimmed sea. ''D. elegans'' differs from all other selenosteids in the structure of its gnathal plates, which are comparatively large, and have long teeth-like prongs. This feature strongly suggests that it was a predatory animal, and used its pronged gnathal plates to prevent seized prey from squirming out of its mouth. The anatomy of its skull, however, is otherwise very typical of selenosteids, being very similar to the genera ''Enseosteus ''Enseosteus'' is an extinct genus of small selenosteid arthrodire placoderms known from the Upper Frasnian Kellwasserkalk facies of Late Devonian Germany and Morocco.

Arthrodire
Arthrodira (Greek for "jointed neck") is an Order (biology), order of extinct armored, jawed fishes of the class Placodermi that flourished in the Devonian period before their sudden extinction, surviving for about 50 million years and penetrating most marine ecological niches. Arthrodires were the largest and most diverse of all groups of Placoderms. Description Arthrodire placoderms are notable for the movable joint between armor surrounding their heads and bodies. Like all placoderms, they lacked distinct teeth; instead, they used the sharpened edges of a bony plate on their jawbone as a biting surface. The eye sockets are protected by a bony ring, a feature shared by birds and some ichthyosaurs. Early arthrodires, such as the genus ''Arctolepis'', were well-armoured fishes with flattened bodies. The largest member of this group, ''Dunkleosteus'', was a true superpredator of the latest Devonian period, reaching as much as 6 m in length. In contrast, the long-nosed ''Rolfosteus ...

Dragonfish Nebula
The Dragonfish Nebula, as it is known for its Stomiidae, appearance on infrared images, is a massive emission nebula and star formation, star-forming region 30,000 light-years from the Sun in the direction of the constellation Crux, the Southern Cross. The Dragonfish Nebula gets its name from a giant toothy fish known as the deep-sea dragonfish. The giant stars in this nebula blow a bubble in the surrounding gas. This bubble is over 100 light-years long and forms the mouth of the dragonfish. The two largest and luminous stars, which form its eyes, are said to be newly formed stars. The stars heat up the surrounding gas, giving off infrared light. The Dragonfish Nebula contains some of the most massive stars in the Milky Way galaxy. This nebula was first discovered in 2010 by Mubdi Rahman and Norman Murray from the University of Toronto. They discovered a cloud of ionized gas which led them to suspect that it was formed from the radiation of nearby stars. Since then more than four ...

Dragonet
Dragonets are small, percomorph, marine fish of the diverse family Callionymidae (from the Greek ''kallis'', "beautiful" and ', "name") found mainly in the tropical waters of the western Indo-Pacific. They are benthic organisms, spending most of their time near the sandy bottoms, at a depth of roughly two hundred meters. There exist 139 species of the fish, in nineteen genera. Due to similarities in morphology and behavior, dragonets are sometimes confused with members of the goby family. However, male dragonets can be differentiated from the goby by their very long dorsal fins, and females by their protruding lower jaws. The Draconettidae may be considered a sister family, whose members are very much alike, though rarely seen. Genera The following genera are classified within the Callionymidae: * '' Anaora'' J. E. Gray, 1835 * '' Bathycallionymus'' Nakabo, 1982 * '' Callionymus'' Linnaeus, 1758 (including ''Calliurichthys'') * ''Diplogrammus'' Gill, 1865 (including ''Ch ...
