How they identify them self • Dolphins have there own unique whistle to identify them self.
How they protect themselves. • Dolphins sleep by resting one half of their brain at a time so that one eye is always open. This allows them to rise to the surface to breathe and to protect themselves from predators.

How the use echo location • Dolphins use echolocation to find pray. • When they do this they can tell what, size , shape, distance, speed, direction, internal structure of the object is.
Conclusion • I think that echolocation is really cool especially for dolphins they can tell the internal structure of anything just using sound waves.
