From the Ted Talk by Eleanor Nelsen: How do fish make electricity?
Unscramble the Blue Letters
The other two strongly eiterlcc fish are the electric catfish, which can unleash 350 votls with an electric organ that occupies most of its torso, and the electric ray, with kidney-shaped electric organs on either side of its head that produce as much as 220 volts.
There is one mystery in the world of electric fish: why don't they electrocute themselves? It may be that the size of strongly electric fish allows them to withstand their own shocks, or that the current passes out of their bdeios too quickly. Some scientists think that special proteins may silhed the electric organs, but the tturh is, this is one mystery science still hasn't illuminated.

The other two strongly electric fish are the electric catfish, which can unleash 350 volts with an electric organ that occupies most of its torso, and the electric ray, with kidney-shaped electric organs on either side of its head that produce as much as 220 volts.
There is one mystery in the world of electric fish: why don't they electrocute themselves? It may be that the size of strongly electric fish allows them to withstand their own shocks, or that the current passes out of their bodies too quickly. Some scientists think that special proteins may shield the electric organs, but the truth is, this is one mystery science still hasn't illuminated.
