Himanshu rajput urf sunny heartbeet asked the Naked Scientists:
   Dear sir mam.. !!
Here i was reading about an Electric Eel
So a question came on my mind that..
"when the eel release current then, why a person can't feel the electric charge.. On the same water away from the fish with a distance above 1000 km...??
as we know water is made up of molequles; which is a good conductor of electricity..
but the person away is unable to feel a single current..!!
WHY.??
What do you think?

Electric eels use electricity to sense the presence of their prey in the muddy waters where they live.
Electric impulses from the eel trigger the muscles of the fish and other creatures, so the eel can feel their movement, and locate them.

A bigger impulse can immobilize their prey.

There are cases of electric eels attacking land animals like horses and humans who venture into their watercourse.
