Eels are already weird creatures with their eerie look, but they can also create electricity. No, I’m not kidding here, these strange-looking little snakes can generate actual electricity. But how do eels create electricity?
First of all, what we want to know is how eels can generate electricity, but not get a shock out of it. I mean, the electricity is inside them, how come they are not hurt or not damaged by it? It seems there is a solid scientific explanation to this: highly specialized nervous system that generates large electric currents.
When the body gives the command to generate electricity, the whole nervous system generates it at the same time and all the cells in the body are included. So the case is as simple as how a battery works: some cells work like the negative side in a battery and others work like a positive side. Hence, the eel does not have a shock.
Another interesting phenomenon comes from the natural habitat of the eels. So eels live in water and we all know water creates additional outlets to the electricity current the eel just generated, so the voltage get higher. If the eel was not living in water and if its natural habitat was air instead, the electricity voltage would be very low.
Last question: how can eels generate electricity to shock other animals but are not shocked themselves? The answer is hidden in the previous part. The amount of electricity generated inside the body of an eel is not much, but it gets very high through water. So the eel is safe, because the electricity current is higher due to water and towards the animal the eel gives shock to. Interesting, ha?
