Acheilognathus macropterus
species of fish
Acheilognathus macropterus is a species of freshwater ray-finned fish belonging to the family Acheilognathidae, the bitterlings. This fish occurs in China and northern Vietnam. It grows to a length of 27.5 centimetres (10.8 in) SL.
Taxonomy and etymology
Acheilognathus macropterus is the name given to this species from Greek words A (without), cheilo (lip), gnathus (jaw), Macro (long), and pterus (feather/wing) due to the fish within this genus only having a lateral, lip fold on the lower jaw and a long dorsal fin on the adult males. The common name for this species is Giant Chinese Bitterling because of its Chinese origin.
There are 39 other species relating to this species at the genus level.
Genome
Mitochondrial genome was found using PCR amplification and DNA sequencing. The double stranded DNA is circular consisting of 13 protein-coding genes, 22 RNA transfer genes, two ribosomal RNA genes, and two main non-coding regions. The genetic composition is similar to other vertebrates and can be useful for future species identification and evolutionary correlations.
Description
Males have longer rays in their dorsal and anal fins, and mating males have a pale pink metallic color, dark abdomen, breeding tubercles on snout, and white spots on anal-fin. Mating females are colorless with an anal-fin being yellow and an 80 mm (3.1 in) ovipositor.
Begin with the source’s own compact description: “Acheilognathus macropterus” is species of fish. The dossier treats that line as a proposition to test through Acheilognathus, macropterus and species, not as a finished interpretation.
Why this record matters
The phrase “species of fish” 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.
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 Q1912945. None of the 0 selected statements returned an explicit reference.
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.
