Overview
The collector places Pira-nu beside Y-Porá and Yaguarón, while noting that regional water-being names can overlap. This particular form is a huge fish with a horse-like head and prominent eyes. It swims near the surface and overturns boats; animals or people falling into the water are quickly devoured. Its danger belongs to river travel rather than to a forest or mountain pursuit.
Its beginning gives the creature a striking material connection: discarded timbó-wood canoes lost in rushing water become the fish. A former vessel thus returns as an enemy of other vessels. Ambrosetti reports that transformation as part of the story, without supplying an individual canoe's history or an identified eyewitness. The account remains a specifically located literary witness to river folklore rather than a description of an actual fish population.
Origins & earliest records
Pira-nu is directly described in the inspected 1917 edition of Ambrosetti's regional collection. The story's transformation of lost canoes is its narrated origin, not a fossil or historical date. The passage gives no securely dated first occurrence, and the 1917 publication should not be treated as the invention of a previously unwritten name.
Records & interpretation
The primary chapter supplies appearance, behaviour and canoe transformation together. It also warns that the three water-being labels sometimes become confused, limiting claims about universally separate identities. The English name is a transliteration of the collector's spelling; a modern zoological identity or proposed explanation was not established by this source inspection.
