It is often called forneyo together with the black sea bass Aristichthys nobilis . It is a freshwater fish of the family Cyprinidae in the order Cypriniformes. It is native to the large rivers of the Asian continent and the lakes and marshes of the plains that follow them. It is large, reaching a total length of over 1m. Its body is laterally compressed and spindle-shaped, with a large head and eyes positioned slightly downward. The outer edge of the ventral side of the body is flattened and keel-like, and its front extends further forward than the base of the pelvic fin. The gill rakers are almost entirely fused together, forming a spongy structure with countless holes on the surface. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
