Overview
Nery places this account on an island in the Haycurupá river near Parintins, Amazonas. The island's raised land appears suitable for cultivation, yet the story explains reluctance to settle there through its feared occupant. Called cheval marin in his French text, the being is described as a fish with the form of a horse. Nery contrasts that description with the Amazonian manatee's familiar comparison to an ox.
The passage then turns to the evidence offered within the account. When the river falls and exposes sandy beaches below the island's hill, visitors are directed to scattered bones, hair, scales and feathers. These remains are interpreted locally as signs of the mysterious horse. The text does not narrate a capture, give the creature a named human identity or describe a particular attack. Its distinctive substance is the connection between an avoided island, seasonal water levels and traces attributed to a horse-shaped river inhabitant.
Origins & earliest records
The directly inspected printed witness is Nery's 1889 Folk-lore brésilien, pages 69–70. He supplies a specific Amazonian location but no named narrator or dated collection visit for this paragraph. River horse is an English editorial translation of cheval marin; it is not presented as a verified Indigenous name or the earliest oral term.
Records & interpretation
The full island paragraph was read through its low-water trace explanation. The mixture of bones, hair, scales and feathers belongs to the reported interpretation, not a scientific specimen description. No independent fieldwork or present-day community version was verified, so the profile retains this bounded historical witness and does not borrow attacks from other aquatic beings.

- Near Parintins an island in the Haycurupá river is said to remain unsettled despite cultivable high ground because a feared river horse prefers it. Nery calls it a horse-shaped fish and compares the metaphor with the river manatee’s cattle name. The account offers scattered bones, hair, scales and feathers exposed at low water as supposed evidence.
ChapterI, printed pp.69–70, complete Haycurupá island paragraph
Nery’s rhetorical question supplies no secure named eyewitness. The listed remains are claimed signs in the account, not forensic proof or actual specimens assigned to a new species. The manatee is a comparison, not identification of the horse. The following toad paragraph is a different being.
