To adapt to their surroundings these sharks can feel electrical fields using special organs called the ampullae of lorenzini. They are located in the snout of the shark. This adaptation allows them to feel the electricity that is released from other animals, making it easier for them to find prey. These sharks are also nocturnal, making it easier to sneak up on fish, however it makes it harder to see and that is where their ability to feel the electricity comes into play.
