Oneirodidae (Dreamers)
Etymology: Oneirodes: Greek, 'oneiros' = a dream or dreamlike or out of a dream (suggesting this fish is so strange and marvelous that can exist only in dreams) (Ref. 86949).
Eponymy: Dr Basil (Vasilis) George Nafpaktitis (1929–2015) (Basileus is a latinization of Basil) was a Greek-born American ichthyologist and marine biologist. [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 5 - 6; Anal soft rays: 4. Characterized by having escal morphology: esca with filamentous, branched anterior appendage two times length of escal bulb, without internal pigment; presence of spots of dark pigment on most branches of anterior appendage; absence of medial escal appendage; rounded or conical terminal escal papilla with two bilaterally placed distal spots of pigment; posterior escal appendage, as long as escal bulb, with an anteroposteriorly compressed distal end, posterior surface of which is slightly concave and darkly pigmented; absence of lateral escal appendage; two pairs of filamentous anterolateral escal appendages; inner pair of branched tapering appendages flanking anterior appendage, each less than one-half length of escal bulb; long and narrow subopercle, dorsal end tapering to a point, without indentation on posterodorsal margin; length of ventral fork of opercle 25.3-28.6% SL; ratio of lengths of the dorsal and ventral forks of opercle 0.54-0.62; absence of epibranchial teeth; presence of teeth on pharyngobranchial II; upper jaw teeth 49-69, lower jaw teeth 46-60; teeth on vomer 4-8; dorsal fin rays 5-6; anal fin rays 4; pectoral fin rays 15-16; head length 38.9-43.4% SL; head depth 37.7-41.7% SL; premaxilla length 32.2-33.3% SL; length of lower jaw 42.1-44.3% SL; length of illicium 45.9-51.6% SL (Ref. 86949).
