Can sharks sense electrical currents?
Yes, scientists have found that sharks have the keenest electric sense yet discovered. Sharks have a system of electroreceptors—special sense organs located in tiny pits in the shark’s skin on the head and lower jaw. These electroreceptors can detect electrical currents and changes in their intensity—as small as thirteen-billionths of a volt per inch. Since all living creatures produce a weak electrical field, the electric sense can help sharks locate prey.
