I love this thing of other animals' senses. Usefull for worldbuilding, believe me. When creating animals, I think on how they see their worlds with different senses. Maybe their hearing is so complex that the can form 3d images in their heads, like bats. Or maybe they smell chemicals that help them in comunication, like ants do. Or even maybe their major sense is the on of toutch, and the can feel the most sutile vibrations, like elephants. Or, if all the other animals produce electromagnetism, thats the best thing to feel.

what is frequency range? to navigate ships/submarines, many counties build transmitters which send ultra low frequency waves. it seems the ulf waves dont influence on them since a wavelength is so long that their detectors cant detect. but the 4g mobile system uses 2-3ghz wave. as the base stations have ground earths in the coast areas, a ghz wave would come into sea water. the ghz wave doesnt propagate longly in the water. but the sharks would detect any of waves. any experiment result?

I read a study on this exact thing. The ampullae are filled with a gel that acts as a thermo-electric semi-conductor. This means that As electric fields affect the fluid, it heats and expands ever so slightly, and that is how the sharks can feel electricity. The shark feels the expansion and heat from the semi-conductor that fills the ampullae.

An idea I have to help is to replicate what the scientists did with the Ray but on a larger scale. Use the pulses to draw them away from the nets, or fishing locals as a whole, this tactic may require a bit of troubleshooting but its simple and it doesnt hurt anything.

So when the tv is turned or or my phone dies, I can feel that. Or in my phones case the lack of. Sometimes I can even here the tv being turned on. It feels similar to someone else being in the room with you that you cant see. That spike or absence of electricity.

the last question seems as pointless as trying to answer the question wether your green is my green. Why try to figure out how different species experience thing while we do not yet know how individuals of our own species experience things

What strikes me as fascinating is how the ampulae remind me of an eye. Socket filled with a jelly like medium and lined with electro-sensitive cells. It's almost like they see the electric pulses as blinking beacons.

so this is the ninth sense, after proprioception nociception
I was looking for this for a while, and there are other senses, like elephants and sub audible sound seeing infrared etc

How to keep them out of nets: stop fishing and killing ecosystems would be a start. But this is still interesting stuff, important to know in order to protect them.

Its based on my faulty human perceptions and logic, but I would imagine it would be kinda like pins-and-needles. A sort of tingling, prickly sensation.

3: 25 Humans have Magnetite crystals in the brain similar to Bacteria.
P. S. This is a stingray not electricray
Playtapus has electroreceptors

I love it when the second they flipped the switch the Ray immediately lamps on the spot. Or was it just nice editing, either way it's halirous

You ever step out of a vehicle when the battery is low it has a way of letting you know it too gets me every time. thats my electric 6th sense

For us it's just a short video but behind this it's a huge hard work, many people's, lot of time, dedication.
Thanks for all your videos.

Or, it could simply feel like human hair. They could just get a annoying feeling just like touching arm hair and not our skin.

Humans can sense electricity too. If you don't believe me, lick a 9V battery. It doesn't hurt much, but you can definitely feel it.

huh, what electricity feels like, welllllll, it feels tingly, something stingy, varies on the voltage, but will hurt non the less.

There is also evidence that the ampuli can detect temperature changes of as little as 1 millionth of a degree, probably Celsius

I learned about ampulae from Endless Ocean 2. It's a shame those games weren't more popular. They were so informative!

This feel like lightning strike envy to anyone else?

If you want to feel electricity, lick a 9V battery. It's not dangerous or very painful, but it will startle you.
