U.S. Navy dolphins keeping all mammals safe

LOS ANGELES - It started in 1960 when the Navy acquired a dolphin named "Notty" in hopes of learning how to create less drag on torpedoes and submarines. They abandoned the biomechanic study when they noticed how smart and trainable they were. It didn't take long before they discovered their amazing sonar and how useful that could be for military operations.

One thing that is certain, is the marine mammals in the Navy help save human lives and have served our country. Now, they are helping us again -- but this time to save their distant relatives in an interspecies rescue mission. Watch the video to see how they are helping save an entire species from extinction.
