It takes a fish . . .

. . . to find a fish.

Item:

Two bottlenose dolphins trained by the U.S. Navy’s marine mammal program have discovered a rare 19th-century Howell torpedo off the coast of San Diego. 

Story.

Oh all right, they were really mammals. Still . . .

The find hints at what the dolphins can actually do, or maybe could do at some point in the future. Locate mines, find robotic detection systems?The question isn't whether dolphins are as smart as humans; rather, are they smarter than unmanned underwater vehicles?
