  2. Aquatic locomotion - Wikipedia

    en.wikipedia.org/wiki/Aquatic_locomotion

    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 ...

  3. Fish locomotion - Wikipedia

    en.wikipedia.org/wiki/Fish_locomotion

    Fish in the order Gymnotiformes possess electric organs along the length of their bodies and swim by undulating an elongated anal fin while keeping the body still, presumably so as not to disturb the electric field that they generate. Many fish swim using combined behavior of their two pectoral fins or both their anal and dorsal fins.

  4. Lateral line - Wikipedia

    en.wikipedia.org/wiki/Lateral_line

    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 ...

  5. Remora - Wikipedia

    en.wikipedia.org/wiki/Remora

    Ram ventilation [11] is the process in which at higher speeds, the remora uses the force of the water moving past it to create movement of fluid in the gills. At lower speeds, the remora will use a form of active ventilation, [11] in which the fish actively moves fluid through its gills. In order to use active ventilation, a fish must actively ...

    Horse galloping The Horse in Motion, 24-camera rig with tripwires GIF animation of Plate 626 Gallop; thoroughbred bay mare Annie G. [1]. 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).

  7. Hydrodynamic reception - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamic_reception

    Arthropods like these northern prawn, and some mammals, detect water movement with sensory hairs such as whiskers, bristles or antennae. In animal physiology, hydrodynamic reception refers to the ability of some animals to sense water movements generated by biotic (conspecifics, predators, or prey) or abiotic sources.

  8. Marine life - Wikipedia

    en.wikipedia.org/wiki/Marine_life

    Pteraspidomorphi is an extinct class of early jawless fish ancestral to jawed vertebrates. The few characteristics they share with the latter are now considered as primitive for all vertebrates . Around the start of the Devonian , fish started appearing with a deep remodelling of the vertebrate skull that resulted in a jaw . [ 323 ]

  9. Tradeoffs for locomotion in air and water - Wikipedia

    en.wikipedia.org/wiki/Tradeoffs_for_locomotion...

    Flying fish are not true fliers in the sense that they do not execute powered flight. Instead, these species glide directly over the surface of the ocean water without ever flapping their "wings." Flying fish have evolved abnormally large pectoral fins that act as airfoils and provide lift when the fish launches itself out of the water.
