Sloanes viperfish, Choliodas sloanes is a predatory, mesoplastic dragonfish that is found in deep-pelagic waters around the world. The species was first described by German scientists Marcus Eleazar Bloch and Johann Gottlob Snyder in their 1801 treatise Sistema Ichthologia: Iconisb CX Painting, Volume 1.
It can range in size from 22mm to 220mm, and is a silver-blue color. It has two rows of photophores, on each side of the central part of its body.
What does sloanes viperfish eat?
Viper fishes are known to eat shrimp, squid, hermit crabs, anchovies, mackerel and other small fish. They swim at high speeds toward the prey by pressing them with their sharp teeth. Other animals that eat VIPRfish include dragonfish, dolphins, and sharks. They live mainly in tropical to equatorial waters.
Distribution
Sloanes viperfish is found in tropical and temperate waters. It extends into the Atlantic Ocean and the western Mediterranean as well as the Indian and Pacific oceans.
Its latitude range is 35 ° N – 55 ° N in the Atlantic, with a maximum of 45 ° N in the Arabian Sea, with a range south of 10 ° N. It is usually at depths ranging from 200 m to 1000 m, and is seen both day and night in contrast to C. wana, whose individuals show monster migration. Some small individuals of sloanes viperfish also exhibit some limited monster migration. Larger people live further north.
The species occurs in tropical and equatorial marine waters worldwide. In Australia, samples have been collected from southwestern Western Australia to the north of the country and Tasmania to the south.

In the Central Mediterranean Sea, sloanes viperfish is eaten as the primary component of the Atlantic bluefin tune diet.
Information on the jaw
The primary feature of interest for sloanes viperfish is its large teeth. When the jaw is closed, the teeth fit together to form a cage so that the victim is trapped.
Its jaw can remain unchanged, it can open up to 90% of its mouth and can hold prey up to 63% of its body size. Its teeth are firmly fixed, more firmly attached to the jaw bone than desperate like any other fish species.
It needs to be able to open its jaw so wide for its large tooth stability. Also, it does not have the floor of the mouth to aid in the expansion of the jaw
The size, shape, location, and a number of teeth in the C-shaped body are different between C. saloni and each fang is highly specialized. sloanes viperfish was probably tempted by his archive to wrap his long surface ray near his mouth with his photophore.
The most prominent premaxillary teeth, which are relatively straight and sharp, can then be used to wound larger prey. The second premaxillary tooth is thought to be used as a knife, holding the large prey. All teeth are assembled in a cage to hold in a small cage.
A study in 25 showed that teeth of sloanes viperfish had dentin tubules. A decade later another study showed the teeth of Aristostomias cintillanus, another member of the family, Stomidae, lacked a dentin tube. The reason for the difference in the presence of dentin tubules of two species of the same family has not yet been discovered.
Diet
A major consumer of sloanes viperfish microfidae or lanternfish, it has a significant impact on their people in the Arabian Sea. An average sloanes viperfish individually receives at least one lantern every twelve days.
However, they are not like them in their diet. They also eat other fish, eggs, and shells. This is another thing that separates them from the C wings, which feed on crustaceans.
It feeds mainly on crustaceans and small fish. The first dorsal fin contains photophores which it believes attract the victim

Reproductive behavior
Little is known about this breed of this species but it is thought to spread outward. This means that the sperm and egg water in the uterus, both male and female, are drained into.
Habitat
Other species such as Dipsea fish, sloanes viperfishes are known to move vertically. During the day it is found in depths of 500 m to 2500 m, but at night it drifts into shallow water (less than 600 m) where food is abundantly grown.
sloanes viperfish is a long-recognized fish with a long-sea fish and a highly recognizable deep-sea fish with fan-like teeth and photophores that illuminate the sides of its body.
Identification
The species can be recognized by its large mouth, long fang-toothed teeth, and long front-page fin rays (up to half the body length). It is a dark dark silver-blue color with pale wings. The sides of the body are covered in hexagonal pigmented areas, each with one or more small photophores.
