Functional adaptation 1
Organ gen erates el ectri ci ty: el ectri c stargaz er
The electroplax organ is a modified muscle in various marine creatures that generates high voltage, low
amperage electricity by reverse polarity.
Make > Generate/convert energy > Electrical energy
"Six groups of fishes (skates, electric rays, electric eel, elephant fishes, electric catfishes, and one
genus of stargazers) have developed electric organs used variously for communication (e.g., concerning
territory or courtship), defense, and stunning prey (electric eel). The electric organ, or electroplax organ,
is modified muscle in which the cells do not contract but rather reverse polarity on stimulation,
producing high voltage (up to 600 V by a large electric eel down to a maximum of about 25 V in an
elephant fish) but low amperage current. The electroplax organ is located in the trunk in most of the
electric fishes but in the tail of skates and in an eye muscle of the stargazer. These and many other
fishes also have electroreceptor organs, called ampullae of Lorenzini in elasmobranchs, to detect
conspecific electrical signals, muscle contractions of hidden prey species, and potentially the
electromagnetic field of Earth for navigation." (Miller 1978:4)
