The Pira-nu, “black fish”, is born in old timber canoes lost in the rapids. This Argentinian fish is of great size, with a horse-like head and big eyes. It swims at the surface of the water to capsize canoes, and it quickly devours humans and livestock that have fallen into the water.

  1. I wonder where the horse-head is from? Were there horses in South- America pre-Spanish Conquistadors; I know the North’s were brought over from Europe. Or is this monster a recent invention?

    Addendum: I acquired Otia Imperialia; which Book mentions the Tarrasque?
