The electric ray and the electric eel are both strange creatures. They both have organs that can discharge electricity. However, although both of them can discharge, they are two different creatures, and they can not be regarded as the same creature because they both discharge. In fact, there are many creatures that can discharge electricity, not only electric rays and eels.
Electric rays and eels have different electrical discharges. The electric ray generates electricity through two electric organs on the inside of its pectoral fins, which are composed of many "electric plates". Electric rays can be controlled by nerve organs to control electricity generation, when they want to generate electricity, they will first send nerve signals, and then release electricity through the tail. The electric ray can even control the intensity of its own discharge, which is a special point. Electric eels use muscles on both sides of their tails to discharge electricity, and their tails have many muscles, which are lamellar and are the organs of discharge.
As mentioned above, the electric ray and the electric eel can discharge electricity, but they are not the same kind of organism, and they discharge different organs. In addition, the intensity of the two discharges is different. There are many different species of electric rays, which can produce between 40 and 220 volts. The electric eel can generate more than 300V, sometimes even 800V. Therefore, from the strength of the voltage, the electric eel is more powerful. But none of them can last very long in the discharge. The electric ray will run out of power after more than ten seconds of continuous discharge, while the electric eel can only last 10-15 seconds.
