The electric eel (Electrophorus electricus, actually a knifefish, not a true eel) can generate discharges of up to 860 volts, confirmed in a 2019 study describing a newly distinguished species (Electrophorus voltai) found to produce higher voltages than previously measured — the highest confirmed electric discharge of any animal, used both to stun prey and for electrolocation.
The question, scope, and sources behind this Registry record.
The electric eel (Electrophorus electricus, actually a knifefish, not a true eel) can generate discharges of up to 860 volts, confirmed in a 2019 study describing a newly distinguished species (Electrophorus voltai) found to produce higher voltages than previously measured — the highest confirmed electric discharge of any animal, used both to stun prey and for electrolocation.
The highest voltage discharge measured from any animal's electric organ.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
