An Anguiloph is an animal in the member of the Eurypharyngidae family. They are a deep sea fish named after their distinctive cross-relationship between the Angler Fish and the Pelican Eel.

This fish is rarely seen by the human world, although deep sea divers have had confirmed sightings of this species off the coast of Japan. The deep sea Anguiloph is the second member of the Eurypharynx and it belongs in the Neopterygii subclass. It is referred to as the death eel, Jukugo (死神) and LED eel.

The Anguiloph is most widely known for its dazzling display of Bioluminescent colors. Like the Cuttlefish, Anguiloph's hypnotize their prey using their bioluminescence to attract prey and distract predators. Living in the deep around 6,000 meters underwater the Anguiloph lives between the Abyssal and the Hadal zones of the ocean. According to legend this creature is known to lurk in the Japan Trench and is rumored to swim out into the waters of the Pacific Ocean.

Anguiloph's have rarely been recorded.

Distribution and Habitat Edit

Japan Trench

Anguilophs live in the Abyssal region of the ocean. They are rumored to be found in the Japan Trench. Due to the immense pressure of the ocean (11,000 psi) and harsh conditions the Abyssal zone contains the Anguilophs need the life giving resources of Hydrothermal Vents to thrive. These hydrothermal vents have a very high temperature which allows abyssal and benthic deep sea creatures to use it's heat and survive. The sulfide rich organism provides a source of community to fish and therefore it provides food for the Anguiloph. Another aspect of the Anguiloph's habitat is Cold Seeps, which provide another alternative and another community of life in the trenches.

Anguiloph eels live in low population densities like many deep sea fishes. Due to this the Anguiloph is a hermaphrodite which can then mate to survive.

Behavior Edit

Hunting and Diet Edit

The Anguiloph eel is an omnivore which means it can consume various types of objects. That which mostly include smaller fish and algae. The Anguiloph fish uses his natural bioluminescence to lure prey into it's mouth.


The outer black skin of the eel is covered in tiny circles which glow in the deep ocean. A fish unknowingly swims up to the eel and the Anguiloph takes his opportunity. The Anguiloph uses a method of opening his mouth widely and sweeps the ocean seabed looking for his next meal. This method is very effective at catching fish because of his back-pointing teeth, this does not allow the fish to escape. Because the Anguiloph traditionally lives alone in the dark, it is able to digest food for long periods of time allowing it to properly nourish itself.

Escape Edit

The Anguiloph eel has a soft exoskeleton which unfortunately does not provide much protection to the eel. Although due to it's black outer body the Anguiloph is able to stealthily move past predators because it blends in with its surroundings. Also the shape of it's body allows the eel to move swiftly through the water with great speed.

Communication and Reproduction Edit

The Anguiloph has a line of photophores which align across the sides of the eel. This function allows the eel to creature to maneuver the intensity of its bioluminescence. The way this is possible is through a chemical process which reacts with the enzyme-substrate reaction. The way the eel uses it, allows the Anguiloph to attract potential mates and prey. The lights create patterns in the ocean.

Using this method and a series of different movement patterns, scientists can differentiate a mating pattern with a hunting pattern. Since the Anguiloph is alone in the vast trenches of Japan it has very acute sense. With these senses the Anguiloph is able to detect potential mates and warp its gender to mate with other Anguilophs. This is a method called sequential hermaphroditism in which species of fish have both male and female gonads.

Female Anguilophs are oviparous. They hatch their eggs outside of their body. This allows the eggs to settle in with the harsh environment and follow in their parents footsteps to become predators.

Chemical Basis for Bioluminescence Edit

The Anguiloph uses fluorescence as a way to attract and catch prey (as stated above) the way this happens is through Bioluminescence.

Bioluminescence is the production of creating and emitting a "cold light". The chemistry behind this is because of a process called chemiluminescence, in chemiluminescence light is released causing the glowing reaction in the Anguiloph. The Anguiloph also uses luciferin which reacts with oxygen to create the blue light seen above. In the Anguiloph eel it's luciferin is stored in the body of the eel. It is used in strips which allow a fluid design and communication with other species.

Growth Edit

Since the eggs of the Anguiloph are born outside of the womb, the Anguiloph's life starts out troubled. After four weeks of developing from the egg they hatch into a world of darkness and survival. The mother Anguiloph teaches the young for roughly three days before she disappears to mate again. The babies use their instinct to find prey and become large predators.

Interaction with other species Edit

The Anguiloph does not have much interactions with other species. This animal is very dangerous and it's bite will cause severe damage when incountered. The eel tends to stay away from conflict and only interacts with animal when it is engaged in hunting and mating. It is interactions in the most primal form, these animals are not to be messed around with because they are killing machines.
