  2. Electric fish - Wikipedia

    en.wikipedia.org/wiki/Electric_fish

    An electric fish is any fish that can generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks 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 ...

  3. Electric eel - Wikipedia

    en.wikipedia.org/wiki/Electric_eel

    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. Their electrical capabilities were first studied in 1775, contributing to the invention in 1800 of the ...

  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 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 the fish's body and tail in the water, and in various specialised fish by motions of the fins.

  6. 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]

  7. Electric organ (fish) - Wikipedia

    en.wikipedia.org/wiki/Electric_organ_(fish)

    In biology, the electric organ is an organ that an electric fish uses to create an electric field. Electric organs are derived from modified muscle or in some cases nerve tissue, called electrocytes, and have evolved at least six times among the elasmobranchs and teleosts. These fish use their electric discharges for navigation, communication ...

  8. Electric ray - Wikipedia

    en.wikipedia.org/wiki/Electric_ray

    The torpedo fish, or electric ray, appears continuously in premodern natural histories as a magical creature, and its ability to numb fishermen without seeming to touch them was a significant source of evidence for the belief in occult qualities in nature during the ages before the discovery of electricity as an explanatory mode.

  9. Genetically modified fish - Wikipedia

    en.wikipedia.org/wiki/Genetically_modified_fish

    Genetically modified fish (GM fish) are organisms from the taxonomic clade which includes the classes Agnatha (jawless fish), Chondrichthyes (cartilaginous fish) and Osteichthyes (bony fish) whose genetic material (DNA) has been altered using genetic engineering techniques. In most cases, the aim is to introduce a new trait to the fish which ...
