Government developing drones that look and act like animals

Our fifth story OutFront: the rise of drones... with fins.

The number of U.S. drones has jumped from about 50 to 7,500 since 2001. But in a new twist, some of these machines are taking to the water like, well, fish.

This drone in particular is called the "Bioswimmer," developed by the Department of Homeland Security to dart into hard-to-reach places underwater.

And it's not the only nature-inspired robot built for the government – there's a "cheetah" and a robo-mule too, both developed by the Defense Advanced Research Projects Agency, or DARPA.

OutFront tonight with more details on these fascinating projects is CNN Pentagon Correspondent Barbara Starr.
