GANOIDEI Meaning and
Definition
-
Ganoidei, also known as ganoid fishes, are a group of primitive, primarily freshwater fishes that belong to the class Actinopterygii. They are characterized by having thick, rhomboid-shaped scales that are covered with a hard enamel-like substance called ganoin, which grants them a shiny, almost armored appearance.
These fishes are known for their fossil records, which date back to the Paleozoic era, indicating their ancient lineage that predates the dinosaurs. However, they are also found in present-day ecosystems, albeit in limited numbers and distribution. Ganoidei are typically found in slow-moving or stagnant water habitats such as lakes and rivers.
One of the key features of ganoidei is their heterocercal tail, meaning that the upper lobe of their caudal fin is longer than the lower lobe. Additionally, they possess a single dorsal fin situated on their back and lack pelvic fins. They also exhibit a unique spiral valve intestine that aids in digestion.
Ganoidei includes various families such as sturgeon, paddlefish, and gars. Sturgeons are highly prized for their caviar, while paddlefish are known for their long, paddle-like snout used for filter-feeding. Gars, on the other hand, have elongated bodies, sharp teeth, and can breathe atmospheric air, allowing them to survive in oxygen-depleted waters.
Although ganoidei are considered ancient fish relatives, they are of great interest to scientists due to their evolutionary adaptations and their significance in elucidating the evolutionary history of fishes.

Etymology of GANOIDEI
The word "Ganoidei" originates from the Greek language. It is derived from the Greek word "ganos", meaning "brightness" or "brightness of a fish scale", and the Greek suffix "-eidos", which indicates "form" or "resemblance". Therefore, "Ganoidei" can be understood to mean "having the form or resemblance of a bright fish scale". This term was created to classify a group of primitive fish characterized by their ganoid scales, which are thick, bony, and diamond-shaped.
