According to an article in Chad Arment's BioFortean Review series, it is known variously as the night jaguar, carraguar, or renegrón. Allegedly native to Colima in Mexico, it is said to resemble a very large all-black jaguar but with coarser fur, and is exceptionally ferocious and fearless. I am only aware of two reports, one extremely brief, the other more extensive, but both of them over a century old. Is this cryptic Mexican cat still being reported today? If so, I'd greatly appreciate receiving any details here.
