Ripsaw catfish

The gentle Niger Ripsaw Catfish or Plated Catfish is the largest member of the Dorididae family of catfish. They have very sharp armored scales running down their lateral lines, plus sharp thorn-like hooks attached to their razor sharp scales. Sometimes literature refers to the doradids as “Talking Catfish” due to the fact that they can be heard to make audible noises, almost as if they are speaking to one another.  

The niger takes a long time to reach sexual maturity, and being slow to reproduce has placed them as code red on the endangered species list.
