Johnsonina
genus of fishes
Johnsonina is a monospecific genus of marine ray-finned fish belonging to the family Triacanthodidae, the spikefishes. The only species in the genus is Johnsonina eriomma, the bullseye spikefish, which is found in the Western Atlantic Ocean.
Taxonomy
Johnsonina was first proposed as a monospecific genus in 1934 by the American ichthyologist George S. Myers when he described its only species Johnsonina eriomma, which he designated as its type species. Myers gave the type locality of J. eriomma as north of Tobago at 18°40'15'N, 60°50'15"W from a depth between 100 and 300 fathoms (600 and 1,800 ft; 180 and 550 m). In 1968 James C. Tyler classified this genus in the nominate subfamily of the family Triacanthodidae, the Triacanthodinae. It is the only species in that subfamily found in the Western Atlantic Ocean. The 5th edition of Fishes of the World classifies the family Triacanthodidae in the suborder Triacanthoidei in the order Tetraodontiformes.
Etymology
Johnsonina suffixes the possessive -ina onto Johnson, honoring the financier Eldridge R. Johnson who sponsored the Johnson-Smithsonian Deep-Sea Expedition of 1933 on which the holotype was collected. The specific name eriomma is a compound of eri, meaning "very", and omma, meaning "eye", an allusion to the large eyes and large eyespot.
Description
Johnsonina has a deep, slightly compressed body with klarge eyes and a small mouth which opens at the front.
“Johnsonina” enters the record as genus of fishes. Crown Archives preserves that source wording while asking what Johnsonina, genus and fishes can confirm, complicate or overturn.
Why this record matters
“Johnsonina” is worth following because a concise public description often conceals a longer documentary argument. Here, Johnsonina, genus and fishes provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q2785280. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1934, 1968 and 1933.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
