Fish anatomy is the study of the form or
morphology of
fishes. It can be contrasted with
fish physiology, which is the study of how the component parts of
fish function together in the living fish. In practice, fish
anatomy and fish
physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.
