Sonar is used to gain information about objects underwater which you can't see because of the darkness and/or opacity of the water.

They both use Sonar to navigate and guide where they are going. Sonar uses sound waves that bounce off of objects and are reflected back at the animal. Submarines also use Sonar.

Sonar uses sound waves to detect objects underwater, while radar uses radio waves to detect objects in the air or on the ground. Sonar is typically used in marine environments, while radar is commonly used in aviation and meteorology.
Sonar uses electricity, so the source of energy is either a generator or a battery.
