Electric Organ Discharge (EOD) in Electric Rays (Torpedo sp.) Electric rays of the families Torpedinidae, Narkidae, Hyphnidae, and an extralimital family, are unique in having two large, kidney-shaped electric organs in the disc on either side of the head.
Does torpedo have electric organ?
The common torpedo can use its pair of large electric organs to stun prey and deter threats. Each organ is comprised of 400-500 columns that contain jelly-filled disks referred to as “electroplaques”. These columns work together and are capable of discharging up to 200 volts either singly or in bursts.
In which fish electric organs are present?
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.
How does torpedo generate electricity?
Electric rays have patches of modified muscle cells called electroplaques that make up an electric organ. These generate an electric gradient, similar to the normal electric potential across most cell membranes, but amplified greatly by its concentration into a very small area.
In which animals electric organs are present?
Electric rays have two large, disk-shaped electric organs, one on each side of the body, that contribute to the disklike shape of the body. The electric catfish of Africa, the knife fish of Latin America, and the stargazers probably use their bioelectric organs as sense organs in the detection of other fishes.
Can electric ray kill human?
Danger to Humans
The Pacific electric ray is very confrontational and if harassed, will swim directly at divers. There are no confirmed mortalities from this ray, but there are some unexplained scuba fatalities in which this ray might have played a part.
Can electric eels kill you?
A full-grown electric eel can generate about 600 volts of electricity. Although there are few documented instances of people dying from an electric eel’s shock, it could happen. … A single jolt could incapacitate a person long enough to cause him or her to drown, even in shallow water.
Where are electric eels found?
Electric eels are found in murky pools and calm stretches of the middle and lower Amazon and Orinoco river basins in South America.
Why 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.
What is electric organ in Torpedo?
The electric currents produced by some species of fishes, such as the Numbfish and torpedo rays are generated in cells called electrocytes. … 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.
How fast is a torpedo?
The VA-111 Shkval (from Russian: шквал, squall) torpedo and its descendants are supercavitating torpedoes originally developed by the Soviet Union. They are capable of speeds in excess of 200 knots (370 km/h or 230 miles/h).
Why are manta rays called Devilfish?
Mantas are known as “devilfish” because of their horn-shaped cephalic fins, which are imagined to give them an “evil” appearance. Manta rays are members of the order Myliobatiformes which consists of stingrays and their relatives.
Is there an electric Stingray?
Electric Stingrays have an ability where they can create an electric discharge for defense. The voltage ranges from specie to specie, but the range is anywhere from 8 volts up to 220 volts. The electric discharge is used in order to stun their prey and can also be used for defense.
Do humans have Electrocytes?
Electricity is everywhere, even in the human body. Our cells are specialized to conduct electrical currents. The elements in our bodies, like sodium, potassium, calcium, and magnesium, have a specific electrical charge. … Electrocytes are specialized muscle like cells that exist at the end of a nerve.
Are electric eels always electric?
no! But electric eels are real. Known by the scientific name Electrophorus electricus, the electric eel is an electric fish able to generate powerful electric shocks. … True eels cannot produce electric shocks like electric eels can.
How do Electrocytes work?
The electric eel generates large electric currents by way of a highly specialized nervous system that has the capacity to synchronize the activity of disc-shaped, electricity-producing cells packed into a specialized electric organ.
