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 living fish. The ...
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 ...
Chondrichthyes (/ k ɒ n ˈ d r ɪ k θ i iː z /; from Ancient Greek χόνδρος (khóndros) 'cartilage' and ἰχθύς (ikhthús) 'fish') is a class of jawed fish that contains the cartilaginous fish or chondrichthyans, which all have skeletons primarily composed of cartilage.
In many fish, a rete mirabile helps fill the swim bladder with oxygen, increasing the fish's buoyancy. The rete mirabile is an essential [ 8 ] part of the system that pumps dissolved oxygen from a low partial pressure ( P O 2 {\displaystyle {P_{\rm {O_{2}}}}} ) of 0.2 atmospheres into a gas filled bladder that is at a pressure of hundreds of ...

Their population status or structure, physiology, behaviour or the level of contamination with elements or compounds can indicate the state of contamination status of the ecosystem. They are particularly useful since they are sessile so that they are representative of the environment where they are sampled or placed. [ 107 ]
Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates.Passive electroreception using ampullae is an ancestral trait in the vertebrates, meaning that it was present in their last common ancestor. [7]
The decapod (crustaceans, such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (). [1] [2] Each segment may possess one pair of appendages, although in various groups these may be reduced or missing.
