Bio-Electric Research Exhibit

Many fishes and other aquatic organisms use electric fields in the water to sense their surroundings: a “sixth sense” that is especially useful in habitats where visibility is poor. The fish in this exhibit produce their own weak electric fields. You may see them “hiding” in clear plastic tubes—their electric sense tells them that they are hidden, even though light passes right through the plastic.

Some electric fishes produce such strong currents that they can stun and capture prey. One of these is the electric “eel”, a relative of the species studied here.
