Source-derived summary

Calophysus macropterus, known natively as the piracatinga/pirácatina, piranambú, pintadinho, zamurito, water buzzard, or by its popular English name vulture catfish, is a species of catfish (order Siluriformes) of the monotypic genus Calophysus of the family Pimelodidae. It is sometimes placed in its own family, Calophysidae.

Description

This species reaches 40 centimetres (16 in) SL, though lengths of 71 centimetres (28 in) have been reported. It originates from the Amazon and Orinoco basins, which encompasses waterways in Brazil, Bolivia, Colombia, Peru, and Venezuela.

The vulture catfish is so named because it is an active scavenger, seeking carcasses in its native waterways to consume in shoals; its feeding action promotes the skeletonization of its food items - they are able to consume all the muscles and viscera from an 80 kilograms (180 lb) cadaver within half an hour - though it apparently avoids feeding on cartilage elements, eyeballs, scalps, and limb extremities. Its voracious nature has led to it becoming an important species in forensic pathology, especially concerning those victims whose corpses ended up in rivers; C. macropterus is often found in association with the cadaver even after it is extracted from the water, often being found under the victim's clothing. This species is also stated to commonly attack fish caught in fishermen's nets and seines as well as those hooked on trotlines or gaffed. They also seem to congregate in areas where fishermen and fishmongers dispose of fish offal.

In the aquarium

This fish is one of the smaller pimelodids available in the trade, and may be appropriate for a large aquarium. It is an adaptable and hardy species.

Editorial summary

Begin with the source’s own compact description: “Calophysus macropterus” is species of fish. The dossier treats that line as a proposition to test through Calophysus, macropterus and species, 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 268-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Calophysus, macropterus and species is the immediate research focus.
Editorial analysis

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.

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 Jul 27, 2026. The linked authority identifier is Q3754015. None of the 0 selected statements returned an explicit reference.

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.
