Eels vs. Catfish: Understanding the Difference

An eel is not a male catfish. Eels are a distinct group of fish belonging to the order Anguilliformes, while catfish belong to the order Siluriformes. Eels have elongated, snake-like bodies, whereas catfish typically have a flattened body with barbels around their mouths. Furthermore, eels do not display sexual dimorphism, meaning there is no distinct difference between males and females, while catfish do exhibit sexual differences.
