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 ...
The skeleton of the head of a perch Parts of a pike's head. 1: liver, 2: gill arch, 3: palate with sharp teeth, 4: in the middle a heart, 5: fragment of spinal cord, 6: brain, 7: spherical lens, 8: scale. Fish heads, either separated or still attached to the rest of the fish, are sometimes used in culinary dishes, or boiled for fish stock.
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. They are, from head to tail:
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 ...
The flattened head and body of various fishes such as stingrays, which also commonly includes the pectoral and ventral fins. distal Remote from the point of attachment. dorsal Pertaining to the back. dorsum The upper (dorsal) surface of the head or body. dorsal fin The fin on a fish's back. dorsal fin origin The most anterior point of the ...
Flatheads are mostly marine demersal fish, often resting directly on the seabed, sometimes partially buried in sand or mud. They can be found in a wide range of depths, ranging from 10 m to the edge of the continental shelf at depths of about 300 m (980 ft). [12] Flatheads are carnivorous, feeding on small fish and crustaceans. They lie in wait ...
The eyes of Winteria telescopa differ slightly from those of other opisthoproctids by their more forward-pointing gaze.. Barreleyes, also known as spook fish (a name also applied to several species of chimaera), are small deep-sea argentiniform fish comprising the family Opisthoproctidae found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans.
They had a movable joint between armour surrounding the head and body. As the lower jaw moved down, the head shield moved, allowing for a larger opening. All arthrodires, save for Compagopiscis , lacked teeth, and used instead the sharpened edges of a bony plate, termed a "tooth plate," as a biting surface ( Compagopiscis had true teeth in ...
