Sandbar Shark ... Like other shark species, this sandbar shark has electroreceptors, hundreds of specialized pores located on and around its head. This sensory system detects the electric fields all animals give off with every heartbeat or movement of a muscle. Sharks use this incredible ability to locate even buried prey, like stingrays on the seafloor. Large sharks can detect an electric field at about three feet (one meter).
