Fish without these features use dynamic lift instead. It is done using their pectoral fins in a manner similar to the use of wings by airplanes and birds. As these fish swim, their pectoral fins are positioned to create lift which allows the fish to maintain a certain depth. The two major drawbacks of this method are that these fish must stay ...
Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves. It is common for fish to use more than one form of propulsion, although they will display one dominant mode of swimming [19] Gait changes have even been observed in juvenile reef fish of various sizes. Depending on their needs, fish can rapidly ...
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells , known as hair cells , which respond to displacement caused by motion and transduce these ...
Low-frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, which responds to nearby movements and to changes in water pressure. [2] Sharks and rays are basal fish with numerous primitive anatomical features similar to those of ancient fish, including skeletons composed of ...
Potamodromous – fish whose migrations occur wholly within fresh water; Oceanodromous – fish that live and migrate wholly in the sea [5] [10] Although these classifications originated for fish, they can apply, in principle, to any aquatic organism. List of diadromous orders and families, and the number of known species: [9] [11]

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
Digging deep burrows in soft sediments allows the fish to thermoregulate, [14] avoid marine predators during the high tide when the fish and burrow are submerged, [15] and lay their eggs. [16] When the burrow is submerged, several mudskipper species maintain an air pocket inside it, which allows them to breathe in conditions of very low oxygen ...
In fish, the lateral line system is used to determine changes in the oncoming flow pattern of a body of water, and the corresponding orientation of the animal toward or away from the current. [6] The lateral line sensory system consists of mechanosensory hair cells that detect the movement of water. [ 3 ]
