Acestrorhynchidae
family of fishes

Acestrorhynchidae is a family of freshwater fish in the order Characiformes, found in South America. Members of this family are known as freshwater barracudas (not to be confused with the unrelated true barracudas of the Sphyraenidae) and biting tetras.
Until recently, this family contained only the genus Acestrorhynchus. However, taxonomic studies have found that the subfamilies Heterocharacinae (originally placed in the closely related Characidae) and Roestinae (originally placed in the more distantly related Cynodontidae) are actually more closely related to Acestrorhynchus, and now they are also placed in this family.
Begin with the source’s own compact description: “Acestrorhynchidae” is family of fishes. The dossier treats that line as a proposition to test through Acestrorhynchidae, family and fishes, not as a finished interpretation.
Why this record matters
The phrase “family 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.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 29, 2025. The linked authority identifier is Q9138782. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
