Source-derived summary

Danaphryne is a monospecific genus of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep sea anglerfishes. The only species in the genus is Danaphryne nigrifilis which is found in the tropical and temperate regions of all of the world's oceans.

Taxonomy

Danaphryne was first proposed as a monospecific genus in 1939 by the Danish ichthyologist Erik Bertelsen with Dolopichthys nigrifilis as its type species. Dolopichthys nigrifilis was first formally described in 1932 by the British ichthyologists Charles Tate Regan and Ethelwynn Trewavas with its type locality given as the South China Sea at 19°18.5'N, 120°13'E, the Dana station 3716 from a depth of around 1,500 m (4,900 ft). The 5th edition of Fishes of the World classifies this taxon in the family Oneirodidae in the suborder Ceratioidei of the anglerfish order Lophiiformes.

Etymology

Danaphryne combines Dana, the name of the Danish fisheries research vessel Dana from which the type was collected, with phryne, a suffix commonly used in the names of anglerfish genera. Its use for these fishes may date as far back as Aristotle and Cicero, who referred to anglerfishes as "fishing-frogs" and "sea-frogs", respectively, possibly because of their resemblance to frogs and toads. The specific name, nigrifillis means "black thread", referring to the pair filaments on the bulb of the esca which are, thick, tapering and are black with white tips.

Description

Danaphryne has between 5 and 7 soft rays in its dorsal fin and 4 or 5 soft rays in its anal fin. The metamorphosed females are distinguished form other taxa within the family Oneirodidae by having a narrow snout, vomerine teeth and a large, almost circular nasal foramen.

Editorial summary

Begin with the source’s own compact description: “Danaphryne” is genus of fishes. The dossier treats that line as a proposition to test through Danaphryne, genus and fishes, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1939, 1932—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Danaphryne, genus and fishes is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “genus of fishes” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q2168465. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939 and 1932.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
