Brazilian scientist Carlos David de Santa had to be extremely careful when descending into rivers and streams while obtaining samples of the Amazon's eel or balm for scientific research.
Even though they were always wearing rubber gloves, there were some shocks.
But to their advantage, during their five years of research, they discovered two new species of electric balm or electric L. One of them has a power of 860 volts, which is the most powerful in any living thing.
The previous record for electric fish was 650 volts.
