WASHINGTON (AP) — Researchers report two newly discovered species of electric eels in South America, one of which can deliver a bigger jolt than any other known animal. The researchers collected 107 eels in four countries and found differences in their DNA, along with minor physical variations. One species had the ability to generate 860 volts of electricity, more than the 650 volts discharged by the only previously identified type of electric eel. While 250 species of fish in South [...]
