Basic Fish Anatomy and Physiology
Fish species vary widely in their anatomy and
physiology. Several popular fish species from two
important families, the Cyprinidae (koi-Cyprinus
carpio and goldfish-Carassius auratus) and the
Cichlidae (discus-Symphysodo,~ sp. and OscarAstronotus
ocellatus) highlight some of the similarities
and differences in gross anatomy. Several
good references provide additional species informationY
