Other Aquatic reports with no dependable place
53 cases, best-documented first. Page 1 of 1.
These accounts don't say where they happened in words we can place (often a video or post that never names a town), so the map can't draw them. They are still cases, with their sources; the map lists them under Cases with no resolvable place. Why some places are estimates or missing
We map claims, not creatures. A case is what some source says someone saw or heard, with the link to that source. It is not proof that anything was there, and a retelling counts once, not as a second sighting.
