Den Den Mushi

Den Den Mushi (電伝虫, Den-den Mushi), literally meaning "electric transmission bug", are snails that usually seen with phones or fax machines attached to their shells. They take the place of telephones and other simmilar machines in the world of One Piece. Despite acting like machines, they are actually animals.

They are capable of making a worldwide signal, and many are large enough to make long distance calls.

The Den Den Mushi can come out in many many styles based on where they are and who owns them. For example, marine Den Den Mushi have the marine symbol painted on their face or on their shell. When a person is speaks through a Den Den Mushi, the Den Den Mushi will mouth the person's speech and display the person's emotions. For example, when someone screams, the snail will scream as well. Den Den Mushi are usually active when someone answers the phone, but once they are hung up, they go to sleep. Since being raised by humans gives them access to plenty of food, Den Den Mushi don't mind being used and tamed.
