Sonar
Sonar is useful to dolphins because it tells them how big and how far something is. It tells them what is surrounding them. It can also tell them if a dolphin is female or male for mating.
No, sonar didn't affect the outcome of World War I. Sonar and electronics technology were not far enough advanced to make a difference in the era from 1910 to 1920. Certainly the war spurred the efforts to develop sonar, but it didn't come far enough fast enough to have any significant effect on WWI at all. A link is provided to the Wikipedia article on sonar, and the section on "History" is brief and easy to read. Why not surf on over and check it out? Our friends there supply knowledge for free.
