South American Jungle Tales — Horacio Quiroga

In South America there is a river called the Yabebiri; and it flows through the city of Misiones. In this river there are many rays, a kind of mud fish like the salt-water skate; and the river, indeed, gets its name from them: "Yabebiri" means the "river of ray fish." The ray is a wide, flat fish with a long, slender tail. The tail is very bony; and when it strikes you it cuts, and leaves poison in the wound."
