Your question: How does an electric eel work ks2?

So instead of using eyes, electric eels emit a weak electric signal, which they use like radar to navigate, to find a mate, and to find prey. Once prey is found, electric eels will use a much stronger shock to stun prey, usually smaller fish. Electric eels can grow up to 8 feet (2.5 meters) in length.

How do electric eels work simple?

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. The arrival of a signal causes positively-charged sodium ions (Na+) to flood into the cell.

What is a fun fact about electric eels?

Electric eel has around 6000 cells (known as electrocyte) that produce electricity. They can generate a power of 600 volts, which is 5 time stronger than the electricity generated in the standard US wall socket. Electric eel can produce electric shock strong enough to knock down a horse.

How do electric eels shock their prey?

An electric eel can deliver a shock because its nervous system contains a number of disc-shaped electrogenic (electricity-producing) cells called electrocytes. … The electric eel’s penchant for shocking its prey may have evolved to protect its sensitive mouth from injury from often spiny struggling fish.

What are electric eels adaptations?

Now imagine this electrical zap five times stronger! Another adaptation of the electric eel is its ability to discharge up to 600 volts of electricity. A group of muscles in its tail store this electricity. In fact, only 1/8 of the fish’s long, slender body contains organs not used for producing electricity.

Do electric eels go blind?

Electric eels live in muddy waters. Mostly blind, they rely on low-level electrical pulses to navigate and explore their surroundings. Higher levels of voltage are generated to stun or kill prey and to protect them from predators.

How old can electric eels live?

On the other hand, also under field observation, female electric eels had a life cycle ranging from 12-22 years. To summarise, electric eels are known to survive 15 years on average in the wild while they can live up to 12 years in captivity.

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).

How does an electric eel not electrocute 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.

How do electric eels breathe?

They are obligate air-breathers, which means they surface for air periodically. Their mouths are heavily vascularized with folds that increase the surface area, allowing them to breathe air, rather than trying to meet their respiration needs through gills in warm, anoxic waters.

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.
