Pelican eels
Eel
An eel is any ray-finned fish belonging to the order Anguilliformes, which consists of four suborders, 20 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage, and most are predators.

What are the adaptations of a pelican eel?
The islands of pelican eel have achieved a unique adaptation to living in the deep oceans with little food there. The pelican eel has developed a huge face with a blocked jaw. There is also a bioluminescence at the tip of the tail of the pelican eel. It is thought that they use it to attract the victim as well as to attract mates.
How deep in the ocean is a pelican eel?
North Atlantic, it seems to have a range in depth from 500 to 3,000 m (1,600 to 9,800 ft). The Pelican eel, ( Eurypharynx pelecanoides ), is a deep-sea fish rarely seen by humans, though it is occasionally caught in fishing nets. It is an eel-like fish and the only known member of the genus Eurypharynx and the family Eurypharyngidae.
What predators do Pelican eels have?
Pelican eels themselves are preyed upon by lancetfish and other deep sea predators. Recent studies have shown that pelican eels are active participants in their pursuit of food, rather than passively waiting for prey to fall into their large mouths. The pelican eel is not known to undergo vertical diurnal migration like other eels.
Do Pelican eels die after reproduction?
Many researchers believe that the eels die shortly after reproduction. The pelican eel has been found in the temperate and tropical areas of all oceans. In the North Atlantic, it seems to have a range in depth from 500 to 3,000 m (1,600 to 9,800 ft).

They can live to be 100 years old. Read more about this fascinating species. They are not shy feeders and due to a powerful mouth they can bite through fine lines. Eels are born in the Sargasso Sea, within the Atlantic Ocean.
How do pelican eels move?
The pelican eel uses a whip-like tail for movement. The end of the tail bears a complex organ with numerous tentacles, which glows pink and gives off occasional bright-red flashes. The colors on its tail are displayed through its light-emitting photophores. This is presumably a lure to attract prey, although its presence at the far end of the body from the mouth suggests the eel may have to adopt an unusual posture to use it effectively. Pelican eels are also unusual that the ampullae of the lateral line system projects from the body, rather than being contained in a narrow groove; this may increase its sensitivity.
What are the characteristics of a pelican eel?
The pelican eel's most notable feature is its large mouth, which is much larger than its body. The mouth is loosely hinged, and can be opened wide enough to swallow a fish much larger than the eel itself. The pouch-like lower jaw resembles that of a pelican, hence its name. The lower jaw is hinged at the base of the head, with no body mass behind it, making the head look disproportionately large. Its jaw is so large that it is estimated to be about a quarter of the total length of the eel itself. When it feeds on prey, water that is ingested is expelled via the gills.
What is a pelican eel?
The pelican eel ( Eurypharynx pelecanoides) is a deep-sea eel rarely seen by humans, though it is occasionally caught in fishing nets. It is the only known member of the genus Eurypharynx and the family Eurypharyngidae. It belongs to the " saccopharyngiforms ", members of which were historically placed in their own order, but are now considered true eels in the order Anguilliformes. The pelican eel has been described by many synonyms, yet nobody has been able to demonstrate that more than one species of pelican eel exists. It is also referred to as the gulper eel (which can also refer to members of the related genus Saccopharynx ), pelican gulper, and umbrella-mouth gulper. The specific epithet pelecanoides refers to the pelican, as the fish's large mouth is reminiscent of that of the pelican.
What is the difference between a pelican eel and a fish?
Its muscle segments have a "V-shape", while other fish have "W-shaped" muscle segments. The pelican eel has an aglomerular kidney that is thought to have a role in maintaining the gelatinous substance filling the "lymphatic spaces" that are found around the vertebrae.
What do eels eat?
The stomach can stretch and expand to accommodate large meals, although analysis of stomach contents suggests they primarily eat small crustaceans . Despite the great size of the jaws, which occupy about a quarter of the animal's total length, it has only tiny teeth, which would not be consistent with a regular diet of large fish. The large mouth may be an adaptation to allow the eel to eat a wider variety of prey when food is scarce. It can also be used like a large net. The eel can swim into large groups of shrimp or other crustaceans with its mouth closed, opening wide as it closely approaches prey, scooping them up to be swallowed. The pelican eel is also known to feed on cephalopods ( squid) and other small invertebrates. When the eel gulps its prey into its massive jaws, it also takes in a large amount of water, which is then slowly expelled through its gill slits. Pelican eels themselves are preyed upon by lancetfish and other deep sea predators. Recent studies have shown that pelican eels are active participants in their pursuit of food, rather than passively waiting for prey to fall into their large mouths. The pelican eel is not known to undergo vertical diurnal migration like other eels.

The fish that inhabit the abyssal area are known as abyssal fish. These animals tend to be grey or black, they are not very structured and without lines. Mobile shapes have long legs; while the specimens tied to the bottom have stems, allowing them to rise above the water layer closest to the bottom, where the oxygen is scarce.
Why do abyssal waters have no sunlight?
This is because the abyssal waters are the reservoir of the salts of the decomposed biological materials that settle down from the upper zones, and the lack of sunlight prevents their absorption by photosynthesis.
