COVER An electric eel (Electrophorus electricus) can generate up to 600 volts using modified muscles that act as batteries. This electrical weapon allows them to remotely activate the muscles in nearby prey to cause either involuntary movement or involuntary immobility, depending on the eel's needs. See page 1231 for details and links to movies that illustrate these findings.
