If this mechanical fish could talk, that might be what it would say. Sadly, it can’t talk. But it can swim in dangerous waters, search for underwater mines, and scout out damage done by the enemy. You see, it isn’t just any fish. It’s a spy for the U.S. Navy.

The robofish is modeled after the Bluefin Tuna. The Bluefin is the biggest tuna in the world. Bluefins can live up to 40 years. They’re made for fast swimming. The Navy’s version is codenamed “Ghostswimmer.” It’s 5 feet long, 100 pounds, and can dive about 300 feet underwater. It acts just like a tuna. It can swim about 46 miles per hour.

The Navy researchers are getting their ideas from the best engineer in the universe: God. He designed creatures to move. His creatures each have different styles of motion. The tuna, for instance, is one of the few fish that uses only it’s back part to move. That makes the design easier to mimic. The tuna also swims quietly and can navigate tight corners. What a great cover!

Ghostswimmer needs more testing. Sometimes on test swims, researchers control it with a joystick. Other times they program it to swim solo. So be on the lookout for more robofish news. But don’t bother looking for it in the water. You’ll never see it coming.
