On one occasion, one of the Bohai Bay offshore fishing fleet up to the East China Sea fish fishing flood out, rule out the possibility of underwater at failure, maintenance staff have encountered a strange situation: just dive underwater, accidentally touched anything sudden numbness in limbs, trembling all over. Local fishermen told them that this is the dwelling at the bottom of a marine elasmobranch - Torpedo at mischief. But soon enough, they trawl catch a Torpedo. It has 60 cm long, flat body, head and chest together, dragging a wooden club-like tail meat rolling, look, much like a large fan . Ship of the local fishermen put money down get it from the Internet onto the deck. In fact, because of the arrest when the continuous discharge, at this time, this “live generator” has been exhausted.

In fact, the discharge of the instinct is not just electricity can skate. Has been found to have more than 500 kinds of fish, their bodies are equipped with “generators”, be able to issue a current. Each of the African electric catfish can produce 350-volt voltage, you can hit small fish die, but also to fishermen knocked unconscious. South American electric eel electric fish is the highest power in a generation, each one can be issued up to more than 800 volts of electricity. It was calculated that 10,000 electric eel at the same time put the electricity for the trams take a few minutes.

Why fish can discharge it?

It turned out that they are inside the body there is a peculiar organ discharge can be generated outside the body at very high voltage. This organ, and some originated in the gill muscle, or tail muscle, and some originated in the eye muscle and glands. Various fish organs discharge location, the shape is different. The electric eel at the tail of the distribution of electrical officer on both sides of the spine muscles, arranged prism; the electric ray electrical Official arranged in the head, chest and abdomen on both sides, looks like two flat kidneys, much of honeycomb from the cells, these cells are arranged in hexagonal column, called the “electricity board.”

The world’s first simple battery - PV cell is the 19th century Italian physicist Volta electric fish in accordance with the principle of the design of the natural organ. With modern science and technology continues to develop, in the study of electric fish, the future will be many new revelations.
