Sharks have special organs called ampullae of Lorenzini, which are small pores located near their mouths and on their heads. These organs contain sensory cells that can detect changes in the electric field around them.
This ability allows sharks to detect prey, even in murky water or when the prey is hiding. It also helps them navigate and communicate with other sharks.
Yes, all sharks have this ability. It is believed to be a primitive trait that has been present in sharks for millions of years.
This varies among different shark species, but on average, sharks can sense electric fields within a few feet of distance.
No, humans do not have the same organs as sharks and therefore cannot sense the electric field perturbation. However, some animals such as electric eels and certain fish have similar abilities.
