Electric Rays among forms of life on Earth

these marine predator rays typically electrocute animals they eat, and these rays respond when touched, by generating
a current of up to 30 amperes and a voltage ranging from 30 up to 220 volts

Original "Torpedo Electric Ray"
the electrical discharge of this cartilagenous fish was well known to ancient Greeks and Romans

range - Mediterranean Sea and eastern Atlantic Ocean, from the Bay of Biscay to coasts of West Africa

Common Torpedo Ray (Torpedo torpedo)   200 volts

This kind of ray can be readily identified by five blue spots on its back.

 

The term torpedo is derived from Latin, `torpor', arising from a Roman description of the numbing, inactivating affect an electric ray's shock may have on any human who comes into contact with it.


 

In about 1900 AD the self-propelled naval torpedo weapon was named after this kind of devastating sea beast.

 

 

 

Electric minds of Planet Earth send a BIG SHOUT OUT to Don in Vancouver, a first classs fellow emeritus of GSA...!
Ad astra and best regards.
