Fish physiology

When threatened, the toxic pufferfish fills its extremely elastic stomach with water.[1]

Fish physiology is the scientific study of how the component parts of fish function together in the living fish.[2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and 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.
