How do fish make electricity? - Eleanor Nelsen

--

Nearly 350 species of fish have specialized anatomical structures that generate and detect electrical signals. Underwater, where light is scarce, electrical signals offer ways to communicate, navigate, find, and sometimes stun prey. But how do these fish produce electricity? And why? Eleanor Nelsen illuminates the science behind electric fish.

Teacher: There’s no electric in 1770s

Eel: Am I joke to you?

It’s my understanding that the spasms produced by the shock from an electric ray can be so violent that it’s not uncommon for the prey fish to actually break its own back.

Are these pokemon water or electric type?

[exoticcucumber]

This is the closest thing to a Pokémon we’ve ever discovered

Turns out that these fishes are one of the first electrical engineers of mother nature (who herself is one), being able to detect, analyse, and transmit changes in electric fields and signals respectively.. how incredible!

Finally learnt how pikachu uses thunder bolt

I legit just figured electric eels was a play on words and it just had some sort of poison on its skin that caused a pain similar to a shock. I never actually figured they could produce true electricity. That is so insane

3:35 can't belive Ted-Ed predicted among us

[kylemossi]

I put this in the search hoping there would be a TED Ed explaining it. You guys rock!

[RamiShreds]

Did each type of electric fish evolve electricity separately or is there a common ancestry?

[anon]

I'm german and just wanted to say that "Schnauzenorgan" litearlly means snout-organ. Have a nice day.

This is so helpful with me. I had wrongly known that the only fish that can create electricity is the electric eel before i watch this. This is so amazing !

[jasonreyes]

Soon we will be powering cars with these. Dudes will be like, "Hey Buddy.. How many eels this thing have?", "well it came stock with 450 eels. I went to the pet shop and added another 50 eels so now im up to a whopping 500 eels.."

Lets farm them and make endless alternative energy source

I love this channel so much! I share it with everyone at my school and even my friends. It nor only makes learning fun but it's entertaining and it helps me retain the information. Keep up the great work!

I asked my wife if she wanted to see my Shnauzenorgan. It didn't end well.

[lucidreality]

This channel is refreshing I can feel the knowledge being absorbed thank you for taking the time to create such a masterpiece 💖

The most important question: how do I charge my phone with it?

[alupade]

Am I the only one who is uncomfortable becauae ells can generate electricity without knowing Ohm's law

[PORTONEGROCUMBIERO]

This is actually one of the subjects in biology that I always wanted to know
