Quick Answer: How are electric rays Electric?

The electric currents produced by some species of fishes, such as the Numbfish and torpedo rays are generated in cells called electrocytes. When an electrocyte is stimulated, a movement of ions (electrically charged atoms) across the cell membrane results in an electric discharge.

How do electric rays make electricity?

The rays and eel produce electricity in different ways. Rays produce electricity through modified muscle cells called electrocytes. Like a row of batteries, stimulated electrocytes move electrically charged atoms (ions) across the cell membrane, creating a combined electric discharge.

Why are stingrays electric?

The electric discharge is used in order to stun their prey and can also be used for defense. There are 69 species that make up 4 families of this type of stingray. The most commonly documented ray of this genus is called the Torpedo Ray.

How do electric stingrays work?

All living creatures produce electricity – even humans – but electric rays have two special kidney-shaped organs that generate and store electricity like a battery. … If prey is encountered, the ray will stun the creature with electricity.

Why is it called the electric ray?

electric ray, also called torpedo, torpedo fish, numbfish, or crampfish, any of the rays of the families Torpedinidae, Narkidae, Narcinidae, and Hypnidae, named for their ability to produce electrical shocks. They are found worldwide in warm and temperate waters.

How do electric rays not shock themselves?

It’s one of the few superheroes of the ‘flat sharks! ‘” In other words, an electric discharge gives these rays a powerful offensive or defensive weapon, but using it (probably) temporarily “blinds” their own electric sense! And to avoid being shocked themselves, they have some biological insulation in place.

Are all rays electric?

Most rays swim using their pectoral fins, either by moving them in an elegant, wave-like motion or by flapping them like a bird. … Rays are not aggressive toward divers, but you should never touch a ray. At best, you will frighten it away, but you could receive a nasty sting or painful electric shock, or worse.

How many volts is electric eel?

Electrophorus electricus—everything about this fish’s scientific name says high voltage! So, it’s no surprise that of the fishes able to generate an electrical discharge, electric eels are the champions, producing up to 600 volts. Electric eels live in muddy waters.

How does an electric eel deliver its shock?

An electric eel can deliver a shock because its nervous system contains a number of disc-shaped electrogenic (electricity-producing) cells called electrocytes. … The collective discharge of electricity from each electrocyte in the chain allows the electric eel to release up to 860 volts.

How do animals create electric fields?

All animals produce electric fields due to the activity of their nerves and muscles. So when the platypus digs in the bottom of streams with its bill, its electroreceptors detect these tiny currents, allowing it to tell living prey from inanimate objects.

How do electric eels and stingrays produce electricity?

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.

How many electric rays are there?

There are over 50 species of electric rays who live in all oceans of the planet. They lie in wait for prey below the sandy bottoms. Torpedo nobiliana is the largest known electric ray. It lives in the North Atlantic Ocean.

How long do electric rays live for?

The average life span for this ray is at least 16 years and possibly up to 24 years. Pacific electric rays feed mainly on fish, including halibut, mackerel, flatfish, kelp bass, anchovies, hake, and herring.
