Ilyophis nigeli Shcherbachev & Sulak, 1997 | |
Ilyophis nigeli is an eel in the family Synaphobranchidae (cutthroat eels). [1] It was described by Yuri Nikolaevich Shcherbachev and Kenneth J. Sulak in 1997. [2] It is a marine, deep water-dwelling eel which is known from Japan, in the northwestern Pacific Ocean. It is known to dwell at a depth range of 700 to 1,800 metres (2,300 to 5,900 ft). Males can reach a maximum total length of 51.3 centimetres (20.2 in). [1]
The species epithet "nigeli" was given in honour of Nigel R. Merrett, credited with making "substantial contributions" to the knowledge of the synaphobranchid eels. [1]
Grenadiers or rattails are generally large, brown to black gadiform marine fish of the subfamily Macrourinae, the largest subfamily of the family Macrouridae. Found at great depths from the Arctic to Antarctic, members of this subfamily are amongst the most abundant of the deep-sea fish.
The pelican eel 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, 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.
Ilyophis is a genus of eels in the cutthroat eel family Synaphobranchidae.
Monognathus, or onejaw, is the only genus of the family Monognathidae of deep-sea eels. The name comes from the Greek monos meaning “one” and gnathos meaning “jaw”, a reference to the large mouth in comparison with the rest of the fish, and also the absence of an upper jaw.
Histiobranchus is a genus of eels in the family Synaphobranchidae. It currently contains the following species:
An eel is a ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 19 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.
Haptenchelys is a genus of deep-water eel in the family Synaphobranchidae. It contains two species. It is found in the Atlantic Ocean and Pacific Ocean at depths of 2,121 to 4,836 metres.
Bathypterois is a genus of deepsea tripod fishes. They are a diverse genus that belong to the greater family Ipnopidae and order Aulopiformes. They are distinguished by having two elongated pelvic fins and an elongated caudal fin, which allow them to move and stand on the ocean floor, much like a tripod, hence the common name. Bathypterois are distributed worldwide with some particular species of the genus having specialized environmental niches, such as lower dissolved oxygen concentrations. Bathypterois have a reduced eye size, highly specified extended fins, and a mouth adapted to filter feeding. They are filter feeders whose main food source is benthopelagic planktonic calanoid copepods, but some variation is seen with maturity in secondary food sources. Bathypterois use their three elongated fins for a wide range of motion from landing to standing on the ocean floor to catching prey, for which these fins serve as specialized perceptory organs. Bathypterois have both male and female gonads at once making, them simultaneous hermaphrodites, whose gonads go through five stages of development following seasonal autumn spawning.
Barathronus is a genus of deep-sea fish that are placed in the family Aphyonidae or family Bythitidae (brotulas), depending on the source.
