860 volts. So powerful were the bumps from one of two electric eel species that scientists discovered in South America, reports the AP. It is the strongest shock among animals known - and more than the eel that was previously alone to be identified as electric and could emit 650 volts.

The researchers collected a total of 107 eels in four countries. The study's lead, C. David de Santana at the Smithsonian's National Museum of Natural History, says the new discovery demonstrates how important it is to protect and study the Amazon rainforest, the AP writes.
