How do electric catfish produce electricity?
How do electric catfish produce electricity?
When the fish wishes to produce an electric current, it triggers the pacemaker nucleus, which sends a signal to the electocytes initiating electrical discharge. The electrocytes then use transmitter proteins to move positive sodium and potassium ions out of the cell, building up an electrical charge.
What is the real name of the electric fish for what did the Egyptians use this animal?
Electric catfish
Several species of this family have the ability to produce an electric shock of up to 350 volts using electroplaques of an electric organ. Electric catfish are found in tropical Africa and the Nile River….

How many gallons does an electric catfish need?
Aquarium Size: It is probably best to house these fish in at least a 30-gallon tank, when they’re less than 3″ long, but a bigger aquarium is always better. Allow at least 5-gallons of water for each Catfish under 3″ long. They’ll eat a huge amount of food and grow very fast.
How many volts does an electric fish produce?
Electric eels can generate an electrical charge of up to 600 volts in order to stun prey and keep predators at bay.
How many amps does an electric catfish produce?
“Electric Fish.” Encyclopedia Americana. “The electric eel (Electrophorous electricus) can produce a discharge of over 500 volts (at about one ampere) and the fresh water African catfish (Malapterurus electricus) produces about 350 volts.”
Are electric eels actually electric?
Electric eels – actually a type of knifefish, not true eels – are notorious for being able to produce a hefty electric shock of up to around 600V. The source of their power is a battery-like array of cells known as electrocytes, which make up around 80 per cent of the eel’s metre-long body.
What is the largest building ever constructed in ancient Egypt?
The first, and largest, pyramid at Giza was built by the pharaoh Khufu (reign started around 2551 B.C.).
Why did stargazers get their name?
The stargazers are a family, Uranoscopidae, of perciform fish that have eyes on top of their heads (hence the name). Their usual habit is to bury themselves in sand, and leap upwards to ambush prey (benthic fish and invertebrates) that pass overhead.
How do you store electric catfish?
Captives do best under low light and in moderately soft water at 76-78 F and 6.5-7.5 in pH. A suitably powerful filtration system is essential, as are regular water changes. Electric catfishes prefer sluggish waters in the wild, and do not abide strong currents in captivity.
Can you buy electric eels?
The electric eel is a dangerous fish and we will not knowingly sell this to anyone with children. These eels, actually the largest knifefish in the World that happens to be shaped like an eel, at maximum size will emit 800 Volts. Our largest specimens are sold only to public aquariums.
Where is Malapterurus found in Africa?
The genus Malapterurus is found throughout western and central tropical Africa and the Nile River. They occur in all major freshwater systems including the Buzi Niger, Ogooué, Omo, Sanaga, Sabi-Lundi, Senegal, Shari, Zaïre and Zambezi River basins,as well as Lakes Albert, Chad, Kainji, Tanganyika and Turkana.
Are Malapterurus electricus mouth brooders?
Malapterurus electricus have been a sea torpedo that managed to migrate upstream. In their natural habitat they form pairs and lay their eggs in excavated cavities or holes. The male takes the eggs into his mouth. There have been rumours that they are mouth brooders.
How do Malapterurus use their EODs?
Because of their very small eyes, members of the genus Malapterurus hunt and navigate almost exclusively by using their EODs. Malapterurus electricus generates different kinds of EOD volleys (differing in the number, rate, and duration of volleys) depending upon the situation encountered.
