Ganoidei - English Definition & Meaning

Definition

Ganoidei is an outdated term that once referred to a group of bony fishes characterized by ganoid scales. Think of them as the vintage cars of the fish world. They included fish like gars and sturgeons. Modern classification has largely abandoned this grouping because it doesn't accurately reflect evolutionary relationships. The term still occasionally appears in older literature. It represents a historical step in understanding fish diversity.

Etymology

"Ganoidei" derives from "ganoid," referring to the type of scales these fish possess. As mentioned before, "ganoid" comes from the Greek word "ganos" (γάνος), meaning "brightness" or "luster." The suffix "-ei" is used in taxonomy to denote a group or class. Thus, "Ganoidei" literally means "those having bright scales." It signifies a classification based on a physical characteristic.
