Weakly Electric Fish
An electric fish is a fish that can generate electric fields. A fish that can generate electric fields is said to be electrogenic while a fish that has the ability to detect electric fields is said to be electroreceptive. Most electrogenic fish are also electroreceptive. Electric fish species can be found both in the ocean and in freshwater rivers of South America (Gymnotiformes) and Africa (Mormyridae). Many fish such as sharks, rays and catfishes can detect electric fields and are thus electroreceptive, but they are not classified as electric fish because they cannot generate electricity. Most common bony fish (teleosts), including most fish kept in aquaria or caught for food, are neither electrogenic nor electroreceptive.

Famous quotes containing the words weakly, electric and/or fish:
“Let’s not quibble! I’m the foe of moderation, the champion of excess. If I may lift a line from a die-hard whose identity is lost in the shuffle, “I’d rather be strongly wrong than weakly right.””
—Tallulah Bankhead (1903–1968)
“The widest prairies have electric fences....”
—Philip Larkin (1922–1986)
“To me heaven would be a big bull ring with me holding two barrera seats and a trout stream outside that no one else was allowed to fish in and two lovely houses in the town; one where I would have my wife and children and be monogamous and love them truly and well and the other where I would have my nine beautiful mistresses on nine different floors.”
—Ernest Hemingway (1899–1961)
