  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 ...

    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 ...

  7. Electroreception and electrogenesis - Wikipedia

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

    An electric fish generates an electric field using an electric organ, modified from muscles in its tail. The field is called weak if it is only enough to detect prey, and strong if it is powerful enough to stun or kill. The field may be in brief pulses, as in the elephantfishes, or a continuous wave, as in the knifefishes.

  8. Brown ghost knifefish - Wikipedia

    en.wikipedia.org/wiki/Brown_ghost_knifefish

    The brown ghost knifefish (Apteronotus leptorhynchus) is a species of weakly electric knifefish in the family Apteronotidae. Only the brown ghost knifefish, a vertebrate, has been proven to have negligible brain aging thus far. In the current study, the basic development patterns of this species are examined, and the hypothesis that minimum ...
