Knife fish are a diverse group of ray-finned fish characterized by their laterally flattened, knife-like body shape. They are known for their unique swimming style, using undulations of a long anal fin to move both forward and backward. Many knife fish species can also generate weak electric fields for navigation, prey detection, and communication. They are primarily found in freshwater environments, with some species inhabiting South America, Africa, India, and Southeast Asia
