The firewood catfish (Sorubimichthys planiceps) a species of South American pimelodid catfish, is the sole member of the genus Sorubimichthys.[2] Known by locals along the Amazon Basin as peixe-lenha,[3] the firewood catfish is so called because it is of little eating value and is often dried and used for firewood.

One of my favorite cats I have encountered! The way they jump out of the water multiple times in a battle is nuts! Jake Didier
I never heard of them and it is one striking looking fish. You have to try hard to get a name like Firewood catfish.
