Creagrutus petilus
species of fish
Creagrutus petilus is a species of freshwater ray-finned fish, a characin, belonging to the family Stevardiidae.
Distribution
It is native to South America, occurring in the upper Machado River, a right‑bank tributary of the Madeira River. The Madeira is one of the largest tributaries of the Amazon, draining vast portions of Brazil, Bolivia, and Peru. The Machado basin lies in Rondônia, Brazil, and contributes to the hydrological complexity of the Madeira system, which is noted for its diverse habitats ranging from fast‑flowing upland streams to extensive floodplains. The species' presence in the Machado highlights its role within the interconnected ecosystems of the southwestern Amazon basin.
Size
This species reaches a length of 4.9 cm (1.9 in).
Etymology
The species name derives from the Latin word for 'thin' or 'slender,' in reference to its relatively elongate body form.

Why this record matters
“Creagrutus petilus” is worth following because a concise public description often conceals a longer documentary argument. Here, Creagrutus, petilus and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q6417724. None of the 0 selected statements returned an explicit reference.
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.
