One Catfish you Don't Want to Catch

The Candirú or Canero (Vandellia cirrhosa) is a freshwater fish belonging to the Catfish group. The species grows only to being one to two inches in length and four to six millimeters wide. It is shaped like an eel and is almost completely transparent, making it almost impossible to see in the water. A fast, powerful swimmer, the fish is smooth and slimy, with sharp teeth and backward-pointing spines on its gill. The Candiru is primarily found in the Amazon and Oranoco rivers and has a reputation among the natives as the most feared fish in its waters.
