Electrical Reception

Sharks can detect very small electrical signals made by moving animals from hundreds of metres away. Covering the shark's snout and lower jaw are lots of small pores called 'ampullae of Lorenzini'. These pores contain hair cells and a jelly matter that detect tiny electrical currents in the water. Sharks use this sense to build an electrical 'map' of their surroundings, allowing them to find prey and avoid predators.
