Researchers at The University of Texas, Austin have discovered that just like we find ourselves plugged in to our cell phones, laptops, and other devices the electric fish generates electrical fields to move throughout the water and attract males in streams and rivers where the water is murky. The electric fish is native to Central and South America. For us, humans, generating electricity is expensive. The electric fish has a sort of dimmer switch to conserve its energy. Researchers have found that the dimmer switch works by sodium channels inserted by the fish from the use of membranes and special cells, called electrocytes. The greater the amount of sodium channels that are in the cell membrane cause the greater the electrical impulse. This article relates to our week 2 studies on electricity and offers us a look at a unique fish that has adapted and evolved to its surroundings by utilizing electrical fields to attract males as well as to keep potential predators, like the catfish, at bay. We as humans have many approaches to generating and storing energy and a great demand for
