Escal appendage pattern B; esca with a tapering, internally pigmented, anterior appendage, two to more than three times length of escal bulb, becoming proportionately longer with growth, and usually bearing two short unpigmented filaments on anterior margin near distal tip; an unpaired, unpigmented, filamentous medial escal appendage usually consisting of numerous branched filaments, flanked on each side by a similar filamentous medial appendage; a truncated terminal escal papilla, with a distal spot of dark pigment in some specimens; a laterally compressed, crescent-shaped, posterior escal appendage, pigmented on distal margin in some specimens; an unpigmented filamentous lateral escal appendage on each side; anterolateral escal appendages absent.
Subopercle without indention on posterodorsal margin; length of ventral fork of opercle 23.3–30.0% SL; ratio of lengths of dorsal and ventral forks of opercle 0.51–0.61.
Epibranchial I with 1–5 teeth along anterior margin; teeth present on pharyngobrancial II; total number of teeth in upper jaw 29–180, in lower jaw 53–160; number of teeth on vomer 4–10; dorsal-fin rays 5–7; anal-fin rays 4, very rarely 5 (only one specimen had 5 anal-fin rays); pectoral-fin rays 16–18.
Measurements in percent of standard length: head length 34.8–47.6; head depth 41.9–64.3; premaxilla length 26.1–38.1; lower jaw length 40.9–54.8; illicium length 15.2–35.3..Additional description as given for the genus and family.
A species of Oneirodes distinguished from all other members of the genus in escal morphology. Although most similar to O. luetkeni, it clearly differs further from the latter and from all other congeners in having the following combination of character states: epibranchial I bearing 1–5 teeth; pharyngobranchial II toothed; upper jaw with 29–180 teeth; lower jaw with 53–160 teeth.
Oneirodes carlsbergi appears to have a relatively narrow circumtropical distribution between approximately 18°N and 8°S. It has been collected in the Eastern Atlantic Ocean as far west as 35°49'W, between 17°49'N and 5°34'S; in the Eastern Pacific as far west as 148°35'W, between 12°07'N and 7°45'S; and in the Western Pacific north of the Philippine Islands (16°55'N, 120°02'E) and in the Banda Sea (4°17'S, 129°34'E). One additional specimen, considerably outside the presumed circumtropical range of O. carlsbergi, was taken off the Irish Atlantic Slope (the holotype of Dolopichthys inimicus). The lectotype is from the Gulf of Panama.
Mesopelagic. The available data (maximum depths reached by fishing gear) suggest that O. carlsbergi has an extremely wide vertical range compared to that of other species of Oneirodes, and that it may be taken at relatively shallow depths. Thirty-six percent of the total known material, including the largest known specimens, was captured by gear fished at maximum depths not exceeding 360 m; 72% was taken by nets fished above 1000 m. Two specimens, 22.5 and 38 mm, were captured by a closing net fished between 690 and 900 m. Data for the Atlantic and Pacific populations were analyzed separately (Pietsch, 1974), but no significant differences in vertical distribution were found.

Although unknown, males of O. carlsbergi are certainly free living and non-parasitic, as is the case with most oneirodid taxa.
Known from 30 metamorphosed females (18–222 mm).

Oneirodes carlsbergi is a species of anglerfish in the family Oneirodidae (dreamers).[3] It takes its name from the Carlsberg Foundation, which funds scientific research.[4][5]
Oneirodes carlsbergi has (in females) a pointed lure (esca) protruding from its forehead; the esca has a tapering, internally pigmented, anterior appendage.[6] The maximum length of females is 15.9 cm (6.3 in).[7][8] It resembles Oneirodes luetkeni but can be distinguished by its large number of jaw teeth.[9]
Oneirodes carlsbergi is mesopelagic and bathypelagic, living at depths of 100–2,000 m (330–6,560 ft) in tropical to temperate parts of the Atlantic and Pacific Oceans.[10] It has also been found in the Banda Sea.[11]
