Chelidonichthys
genus of fishes
Chelidonichthys, the smallscaled gurnards, is a genus of marine ray-finned fishes belonging to the family Triglidae, the gurnards and sea robins. These gurnards are found in the Eastern Atlantic, Indian and Western Pacific Oceans.
Taxonomy
Chelidonichthys was first formally described as a genus in 1873 by the German zoologist Johann Jakob Kaup. In 1896 Trigla hirundo was designated as the type species of the genus by David Starr Jordan and Barton Warren Evermann, T. hirundo is now treated as a junior synonym of Trigla lucerna which had been described by Linnaeus in 1758 from the "Northern Ocean". The genus is classified into three subgenera by some authorities, Cheilonichthys, Aspitrigla and Trigloporus. The genus name combines chelidon, meaning "swallow", with ichthys, meaning "fish", probably an allusion to the specific name of the type species, hirundo, which also means "swallow".
Species
There are currently three subgenera and eleven recognized species in this genus:
subgenus Chelidonichthys Kaup, 1876
Chelidonichthys capensis (G. Cuvier, 1829) (Cape gurnard)
Chelidonichthys gabonensis (Poll & C. Roux, 1955) (Gabon gurnard)
Chelidonichthys ischyrus D. S. Jordan & W. F. Thompson, 1914
Chelidonichthys kumu (G. Cuvier, 1829) (Bluefin gurnard)
Chelidonichthys lucerna (Linnaeus, 1758) (Tub gurnard)
Chelidonichthys queketti (Regan, 1904) (Lesser gurnard)
Chelidonichthys spinosus (McClelland, 1844) (Spiny red gurnard)
subgenus Aspitrigla Fowler, 1925
Chelidonichthys cuculus (Linnaeus, 1758) (Red gurnard)
Chelidonichthys obscurus (Walbaum, 1792) (Longfin gurnard)
subgenus Trigloporus J. L. B. Smith, 1934
Chelidonichthys africanus (J. L. B. Smith, 1934)
Chelidonichthys lastoviza (Bonnaterre, 1788) (Streaked gurnard)
In addition, the fossil species †Chelidonichthys macroptera (Arambourg, 1928) is known from the latest Miocene (Messinian) of Algeria.
Characteristics
Chelidonichthys gurnards have bont plates along the base of first spiny dorsal fin but not along the base of the second soft rayed dorsal fin. The scales on the body and caudal peduncle are small and there are typically 60 scale rows along the lateral line but no scales on the head. There is a deep groove on the occipital region.
This brief starts where responsible research should: with the source description of “Chelidonichthys” as genus of fishes. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of fishes. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q1983412. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1873, 1896, 1758 and 1876.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
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.
