bioelectric organ, also called electric organ, system of tissues specialized for the production and use of electrical power in a living organism. … (Various other tissues and organs also possess the capacity to produce electricity—the skin of frogs and the heart, brain, and eye of higher animals including humans.)
What animals have electric organs?
Electric eels (Electrophorus electricus) have three electric organs—the main organ, Hunter’s organ, and Sach’s organ—which are made up of modified muscle cells. Electric eels (Electrophorus electricus) are freshwater fish found in South America. They can discharge enough electricity to jolt a human being.
Is electricity an organ?
electronic organ, also called electric organ or electrophonic organ, keyboard musical instrument in which tone is generated by electronic circuits and radiated by loudspeaker.
Where are electric organs located?
Electric organs are found exclusively in fishes. Among chondrichthyans, or cartilaginous fishes, electric organs are found only in the skates and electric rays. The electric organs of these two groups evolved independently, since they develop from different skeletal muscle masses.
How do electric organs work biology?
In biology, the electric organ is an organ common to all electric fish used for the purposes of creating an electric field. … The electric discharge from this organ is used for navigation, communication, mating, defense and also sometimes for the incapacitation of prey.
Why do eels shock?
Take the electric eel, Electrophorus electricus. An adult can stun its prey by firing 500 V discharges into the water as it hunts. … When an electric eel senses prey, or a threat, it sends a signal through its nervous system to the electrocytes. Nerve fibres join each electrocyte on one of its sides, but not the other.
What are the electric organ in fishes?
Electric organs are masses of flattened cells, called electrocytes, which are stacked in regular rows along the sides of certain fishes. Electroreceptors are also found in some nonelectric fishes and in some amphibians.
Where did electric organs in fishes come from?
So-called neurogenic electric organs arise from specialized axons originating in the spinal cord, while myogenic electric organs arise from transformed skeletal muscle, typically in the trunk region of the fish. Electrocytes employ mechanisms of electrical excitability similar to those of normal nerve and muscle cells.
Can humans produce electricity like eels?
Fish with exotic powers have long captured the imagination. Although structurally similar to batteries, the electric organs (EO) of the fish who wield them are operationally more like the Marx generators. …
Why do electric organs have two keyboards?
Each keyboard on an organ controls a separate division enabling the organist to have a different type of sound available to them simply by reaching to a different keyboard. The divisions can be coupled together creating the grand and inspiring sound that has earned the organ the title of “King of Instruments”.

When was the electronic organ invented?
The first successful electronic organ was developed in 1928 in France by Edouard Coupleux and Armand Givelet. It used electronic oscillators in place of the pipes of a conventional organ and was operated with keyboards and a pedal board.
How does an electric eels create electricity?
Electric eels have three pairs of abdominal organs that produce electricity: the main organ, Hunter’s organ, and Sachs’ organ. These organs make up four fifths of their body, and give electric eel’s the ability to generate two types of electric organ discharges: low voltage and high voltage.
Are electric organs striated?
All three electric organs originate from striated muscle fiber as indicated by the presence of a striated structure in the undeveloped electroplates.
What do electric eels eat?
Electric eels are found in murky pools and calm stretches of the middle and lower Amazon and Orinoco river basins in South America. Juveniles feed on invertebrates, such as crabs and freshwater shrimp. As adults, they eat amphibians, fishes and crustaceans.
How many fishes are electric?
One type that seems to come out of fiction is the electric fish. There are around 350 types of electric fish in the world. A fish that is able to generate electricity is called electrogenic, but some can also detect electric fields, which are electropositive.
Do electric eels produce AC or DC?
How do electric eels release their shock? Electric fish can either emit an electric organ discharge (EOD), in pulses, or in a wave-like (sinusoidal) manner. Furthermore, they can either produce DC, direct current (monophasic) or AC, alternating current (biphasic).
What was the electric eel called before?
Indigenous people in Venezuela called it arimna, or “something that deprives you of motion.” Early European naturalists referred to it as the “numb-eel.” And for 250 years, since it was first given a Latin name, Western scientists have known it as Electrophorus electricus, the electric eel, the sole member of its genus …
How do jellyfish make electricity?
Green fluorescent protein produced by the jellyfish Aequorea victoria (pictured above) can be used to create solar cells. “When exposed to ultraviolet light,” New Scientist explains, the protein “absorbs photons and emits electrons, which travel around a circuit to produce electricity.”
What is electric organ in Torpedo?
The electric organs of the torpedo rays contain about 45 columns of around 700 electrocytes. Electrical discharges escape through the dorsal surface of the fish. This is because the dorsal surface of both the electric organ and the body have less resistance than the surrounding tissues.
What is luminous organ?
A number of fishes especially marine species are known to produce characteristic light through their special organs called luminous organs. These organs are commonly found in fishes living in deep-sea where the sunlight ceases to enter. … The luminous organs or photophores are special gland cells of the epidermis.
Why do some fishes create electrical signals?
It emits pulse-like electric signals for a multitude of reasons, depending on the species. Many species use it for communication, while others use it for electrolocation, hunting, or defense. Their electric signals are often very simple as well as stereotyped, ie.
Where do electric fish live?
They live in the murky streams and ponds of the Amazon and Orinoco basins of South America, feeding mainly on fish, but also amphibians and even birds and small mammals.
How did electric fish evolve?
Scientists have found how the electric fish’s jolt evolved. Biologists identified the regulatory molecules involved in the genetic and developmental pathways that electric fish have used to convert a simple muscle into an organ capable of generating a potent electrical field.
Can an electric eel power a light bulb?
Electric eels can release between 10 to 850 volts, with one big jolt able to light up to a 40-watt DC light bulb.
How does an electric eel not shock itself?
The reason the eel does not shock itself is that the electrical shock is distributed by its whole body, which is roughly the size of an adult man’s arm. To make muscles in an arm to spasm you need 200 milliamps of current flowing for a minimum of 50 milliseconds.
Can an organ have 5 keyboards?
The organ is played with at least one keyboard, with configurations featuring from two to five keyboards being the most common.
How heavy is an electric organ?
The original Hammond organ was never designed to be transported regularly. A Hammond B-3 organ, bench, and pedalboard weighs 425 pounds (193 kg). This weight, combined with that of a Leslie speaker, makes the instrument cumbersome and difficult to move between venues.
Can you lay an electric organ on its back?
There are two main ways to transport your organ, the first being in its standard upright position, and the second being on its back. … If your organ does have reverb springs but it is necessary to transport it on its side, be sure to check if they are oil-filled, as some old organs are.
