Oneirodes – Taxon details on Integrated Taxonomic Information System (ITIS).

Oneirodes is a genus of is a genus of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes. These predatory, deep-sea fishes are found in around the world. This is the type genus, and the most speciose genus, of the family Oneirodidae. They are sexually dimorphic but, like most taxa within their family, the small males are free living and are not sexual parasites on the larger females. Only the females are used to identify the species in this genus as no species specific charaxcters have been found for males.
Taxonomy

Oneirodes was first proposed proposed as a monospecific genus in 1871 by the Danish zoologist and naturalist Christian Frederik Lütken when he described Oneirodes eschrichtii.[1] Lütken gave the type locality of O. eschrichtii as off the western coast of Greenland.[2] The 5th edition of Fishes of the World classifies this genus in the family Oneirodidae in the suborder Ceratioidei of the anglerfish order Lophiiformes.[3] Theodore Gill named the family Oneirodidae in 1878[4] with O. escherichtii as its only species, making Oneirodes the type genus of its family.[5]
Etymology

Oneirodes means "dream-like". Lütken did not explain this choice of name, David Starr Jordan and Barton Warren Evermann suggested in 1898 that the name referred to the small, skin-covered eyes. Alternatively, in 2009 Theodore Wells Pietsch III proposed that the name was given because a “fish so strange and marvelous that it could only be imagined in the dark of the night during a state of unconsciousness”.[6]

Characteristics

Oneiriodes dreamers are characterised by having spines on the sphenotic bone, an deep incision on the rear edge of the operculum, rod shaped pelvic bones which are not expanded or expanded only slightly at the tips. The lobe of the pectoral fin is short and wide with the length of the lobe being less than thatof the longest pelvic fin rays. There is a spine on the symphysis of the lower jaw and the lower margin of this symphysis is convex, The rays of the caudal fin have no internal pigmentation and the black skin on the caudal peduncle does not extend past the base of the caudal fin. The [[Illicium (fish anatomy) merges from between the frontal bones, the frontal bones are curved on their upper margins abd the subopercular bone is short and wide woth a nearky circular lower part. There are 4, occasionally 5 , soft rays in the anal fin.[11] A unique character of the metamorphosed females of Oneirodes is that the posterior end of the pterygiophore of the illicium emerges from the skin on the back, behind the head.[12] The males have unpigmented skin between the nostrils and the inner surface of the subopercle is also unpigmented . The caudal peduncle has no subdermal pigments and there are between 7 and 13 denticles on the lower jaw.[13] The females range in standard length from 10 to 213 mm (0.39 to 8.39 in), and the published species descriptions are based on females as there are no known morphological character that separate the males by species, the males are free living and non-parasitic. Male specimens measure between 7.5 and 16 mm (0.30 and 0.63 in).[11]
Distribution and habitat

Oneirodes dreamers are found in the Atlantic, Pacific and Indian Oceans. They are bathydemersal fishes found at depths between 0 and 3,800 m (0 and 12,467 ft).[14][15]
