15 Facts You Didn’t Know About Sharks
Sort of. Sharks have an array of electroreceptors in the pores around their mouths. These receptors can detect tiny electromagnetic fields made by things as seemingly inconsequential as muscle contractions or movements in living organisms. In the conductive environment of sea water, sharks have been measured detecting electric fields as weak as 5/1,000,000,000 of a volt per centimeter of receptor tissue.There is no hiding from a shark - this is almost as conductive as the most high-tech man-made materials.
