The highest voltage of the observation history of 860 volts is reported

The electricity generated by Denki eels is dangerous for humans, but until now it was reported that the maximum voltage of Denki eels was 650 volts. However, in a new study, it was announced that it was confirmed that it was able to discharge up to 860 volts, well above 650 volts.

Most powerful electric eel yet puts all other electric eels to shame

Newly identified electric eel is the most powerful ever found, say scientists-CNN

Researchers from the Sao Paulo Research Foundation and the National Smithsonian Museum of Natural History have analyzed 107 eels sent from Brazil, Amazon, Suriname, French Guiana, Guyana and other countries. And 'E. voltai' were reclassified. As this classification standard, the “voltage” of the electric discharge of Denki eel was used for the first time ever.

It was recorded that the eels were actually discharged, and it seems that there was a maximum discharge of 860 volts. Until now, the maximum discharge from animals has been 650 volts.

Researchers have found that the voltage of eels is related to whether they live. E. voltai lives in high-transparency, high-oxygen water in the highlands, but this water is characterized by low electrical conductivity due to its low salt content. For this reason, higher voltage is required for eels to attack the enemy.

E. varii and E. voltai are huge species that grow up to 2.4 meters, but were first found in Amazon in this survey. 'A new species of fish 2.4 meters was found 250 years after the scientific search, can you imagine how many creatures have not been found yet?' Carlos David of the National Smithsonian Museum of Natural History de Santana says.

For the past 250 years, we knew that Amazon eels lived in the Amazon basin, but it was a mystery how many species existed. Scientists have long thought that eels inhabit the region are the same species, but as a result of analyzing the genetic material, skull shape, voltage, etc. in this survey, there are actually three species with different eels It turned out to belong to.

Researchers believe that three different species evolved from a shared ancestor that lived about 7.1 million years ago.

Denki eel's ecology is also used for technological innovation, and this new discovery is expected to be used in the technical and medical fields.
