Visitors to the Tennessee Aquarium in downtown Chattanooga, the United States, are treated to a shocking Christmas attraction this December. An electric eel by the name of Miguel Wattson is powering a festively decorated Christmas tree near its tank.
Every time Miguel Wattson releases a jolt of electricity, sensors in the tank pick up the signals, amplify it and feed it to the lights decorating the Christmas tree. Whenever you see the lights flicker, you know that Miguel Wattson is up to something. An electric eel typically discharges very little, about 10 volt, when at ease or when navigating in the dark (eels have very poor eyesight so they use electric jolts the same way bats use sonar to find obstacles), but when hunting for food or when plain excited, eels put out stronger voltages. An adult eel, more than four feet in length, can discharge as high as 800 volts, enough to stun preys it plans to devour.
