Many marine animals, from tiny clams to big fish, produce electric signals. Sharks and other ocean predators, including skates and rays, sense those electric fields. They do it using organs known as ampullae (AM-puh-lay) of Lorenzini. Scientists call such tissues electroreceptors because they detect electric fields.
How do angel sharks protect themselves?
