  2. Electric fish - Wikipedia

    en.wikipedia.org/wiki/Electric_fish

    An electric fish is any fish that can generate electric fields. Most electric fish are also electroreceptive, meaning that they can sense electric fields. The only exception is the stargazer family (Uranoscopidae). Electric fish, although a small minority of all fishes, include both oceanic and freshwater species, and both cartilaginous and ...

  3. Electric eel - Wikipedia

    en.wikipedia.org/wiki/Electric_eel

    Gymnotus RegiusDelle Chiaje 1847. Electrophorus multivalvulusNakashima 1941. The electric eels are a genus, Electrophorus, of neotropical freshwater fish from South America in the family Gymnotidae. They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts.

  4. Electroreception and electrogenesis - Wikipedia

    en.wikipedia.org/wiki/Electroreception_and...

    Electroreception and electrogenesis are the closely related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups of fishes (most famously the electric eel, which is not actually an eel but a knifefish) to stun prey.

  5. Fish locomotion - Wikipedia

    en.wikipedia.org/wiki/Fish_locomotion

    Fish locomotion. Fish, like these yellowfin tuna, use many different mechanisms to propel themselves through water. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of ...

  6. Robot fish - Wikipedia

    en.wikipedia.org/wiki/Robot_fish

    A robot fish is a type of bionic robot that has the shape and locomotion of a living fish. Most robot fish are designed to emulate living fish which use body-caudal fin (BCF) propulsion, and can be divided into three categories: single joint (SJ), multi-joint (MJ) and smart material -based "soft-body" design.

  7. Electric ray - Wikipedia

    en.wikipedia.org/wiki/Electric_ray

    The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes / t ɔːr ˈ p ɛ d ɪ n ɪ f ɔːr m iː z /. They are known for being capable of producing an electric discharge, ranging from 8 to 220 volts, depending on species, used to stun prey and for defense.

  8. Aquatic locomotion - Wikipedia

    en.wikipedia.org/wiki/Aquatic_locomotion

    Aquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals .

  9. Electric catfish - Wikipedia

    en.wikipedia.org/wiki/Electric_catfish

    Electric catfish or Malapteruridae is a family of catfishes (order Siluriformes). This family includes two genera, Malapterurus and Paradoxoglanis, with 21 species. [1] Several species of this family have the ability to generate electricity, delivering a shock of up to 350 volts from its electric organ. [2]

  10. Electrophorus electricus - Wikipedia

    en.wikipedia.org/wiki/Electrophorus_electricus

    Electrophorus electricus is the best-known species of electric eel. It is a South American electric fish. Until the discovery of two additional species in 2019, the genus was classified as the monotypic, with this species the only one in the genus. [2] Despite the name, it is not an eel, but rather a knifefish. [3]

  11. Fish fin - Wikipedia

    en.wikipedia.org/wiki/Fish_fin

    Ray fins on a teleost fish, Hector's lanternfish. (1) pectoral fins (paired), (2) pelvic fins (paired), (3) dorsal fin, (4) adipose fin, (5) anal fin, (6) caudal (tail) fin. Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim.
