Rays

All these creatures have broad, flat bodies, either round or rhomboid, and live on the bottom of the sea, whence they are often brought up in trawls. Trawlermen take care to cut off the tails of the big ones quickly before they can do damage or cause injuries. And they watch out for the dangerous sting rays and the electric rays (not listed here as they are not good to eat). The electric rays are capable of discharging electricity by which they stun their prey. Large specimens have been rated at 220 volts/8 amps. Classical writers noted that a dangerous shock could pass along a spear to the hands of a fisherman; and Plato described Socrates as being like an electric ray in administering the shock of doubt to his hearers.
