Most dragonfish grow about 5-6 inches long. However, the black dragonfish reaches 16 inches. These deep-sea fish live at depths of 200-5,000 meters in coral reefs, rarely seen by humans. Some dragonfish species are eaten, but the black dragonfish is extremely poisonous and lethal if ingested.
The female black dragonfish reaches 16 inches long while the male only grows to 2 inches. They are bioluminescent, seeing their own light to spot prey.
Idiacanthus atlanticus, the black dragon, dwells from 25°S to 60°S at depths down to 2,000 meters. It is a small fish, about 15 centimeters long despite its gruesome look.
Dragonfish eat aquatic invertebrates, insects, larvae, and scavenge carcasses. They reach about 6 1/2 inches long. Several popular species are in the Stomiidae family, but over 300 species across 28 genera are mostly unknown. Appearance-wise, dragonfish have elongated, armored bodies and large mouths, growing over 2 feet long.
The female black dragonfish reaches 16 inches long while the male measures just 2 inches. They are bioluminescent but see their own light. The population size is unknown. An interesting fact is that they can emit red light from their eyes.
Dragonfish live about 10 years, reaching 6.5-15 inches long. The black dragonfish is a strange, slender fish living at 5,000-7,000 foot depths. A golden dragon fish does not actually exist.
Scaly dragonfish grow up to 12.6 inches at depths of 656-4,921 feet. Dragonfish have bioluminescent photophores helping them survive extreme depths.
What are the different types of dragonfish?
Dragonfish are found in oceans worldwide. Species live in deep waters, up to 5,000 feet below the surface. There are over 300 species of dragonfish across 28 genera. Six main types of dragonfish are the Black Dragonfish, Malacosteus, Idiacanthus, Viperfish, Eustomias, and Aristostomias.
The long, slender body of the dragonfish allows graceful movement through water. Dragonfish are carnivores that ambush prey. Some species migrate vertically, following prey and avoiding predators.
Dragonfish have large mouths filled with prominent teeth, giving them a frightening appearance. They range from about 6 to 12 inches long. The deep-sea habitat and menacing looks belie the small size of most species.
The bioluminescence of some species helps attract prey in the darkness of deep waters. Dragonfish use camouflage to remain hidden until prey approaches. Their stark black bodies paired with transparent teeth create a threatening look.
While intimidating and vicious hunters in their deep-sea realm, dragonfish pose no threat to humans. Their habitat is too deep for contact. However, that habitat allows them to survive even in polar seas along other fish. The extreme environment shapes their evolution as hearty predators.
Is dragonfish a bioluminescence?
The black dragonfish produces bioluminescence using an enzyme called coelenterazine. This emits a blue light which helps them catch prey in the deep sea. Dragonfishes live for about 10 years. Some species have evolved from blue-light sensitivity to red-light sensitivity. Predators of dragonfish include red founder fish.
Bioluminescence provides light in the darkness. It can help seek a mate, lure prey, and divert predators. The light comes from a photophore organ. Photophores along the sides of the body also produce light.
The longest bioluminescent creature is the scaly dragonfish at 32 centimeters. The comb jelly and firefly squid emit the most beautiful bioluminescence with their rainbow and blue glows. Dragonfish use bioluminescence to lure prey to their large mouths and sharp teeth. Despite this, larger deep-sea creatures and sharks prey on dragonfish.
Dragonfish see red light. They live 200-2000 meters below the surface where almost no sunlight reaches. Bioluminescence has evolved to become vital for communication, navigation and hunting. Dragonfish are the only marine animals that see red.
Jellyfish typically feed on microscopic algae, fish eggs and other jellyfish. A number of species use bioluminescence for defense to startle predators.
Dragonfish are small, elongated fish encased in armor. They are carnivorous, feeding on fish and crustaceans based on availability. There are about five species of dragonfish. All vertebrates have a notochord running down their back. Dragonfish can lift their upper jaw up as much as lowering their lower jaw to feed.
Why are they called dragonfish?
The name Dragonfish comes from the large head, broad jaw, and usually protruding teeth that give the fish a scary, dragon-like look. Unassuming dragonfish lurk in the twilight zone over 1,600 feet under the ocean’s surface. The deep water Black Dragonfish feeds on crustaceans and small fishes. It uses its sharp and large teeth to grab its prey. It also uses its teeth to scrape algae from rocks.
Dragonfishes are known to be dangerous top deep sea predators. Dragonfishes are small, about 6.5 to 15 inches long. They are carnivorous, primarily feeding on other fish and crustaceans. Their diet depends on available prey. Dragonfish use bioluminescence to lure prey. Once drawn close by the light, they capture it with large mouths and sharp teeth. Their ability to open their jaws wide allows swallowing prey almost as large as themselves. Despite being top predators, dragonfish face threats from larger deep-sea creatures like certain sharks and fish.
There are several popular dragonfish species in the Stomiidae family. The six main types are Black Dragonfish, Malacosteus, Idiacanthus, Viperfish, Eustomias, and Aristostomias. However, over 300 species distribute over 28 genera. Eastern people associate them with dragon legends, so they are often called dragonfish.
