Sharks may be more sensitive to electric fields than any other animal. Sharks have a special network of jelly-filled canals in their head called the ampullae of Lorenzini that detect electric fields. This lets the shark pick up weak electrical stimuli from the muscle contractions of animals. It may also serve to detect magnetic fields which some sharks may use in navigation. Many small pores open up on the skin, detecting the intensity and direction of vibrations in the water.
Sharks are very sensitive to low frequency sounds and have good directional hearing.
The endolymphatic pores on the top of a shark's head are the only external evidence of its ears. Inside the endolymphatic pores are the endolymphatic ducts which lead to the macula neglecta and a series of semicircular canals with which sharks hear.
