Only when placed directly on top of the mines!

Dolphins aren't so intelligent after all. Check out the fruit of this study:

"Dolphins have a popular reputation for being excellent communicators," Lindell said. "But our study group offered only three types of response to every question we posed: a nonsensical, labored wheezing, an earsplitting barrage of unintelligible high-pitched shrieks, and in extreme cases, a shrill, distressed scream."

And this important finding:

Even the dolphins' proven ability to navigate through a form of sonar called echolocation was ineffective on land.

"The military has claimed great success in training these mammals, utilizing their echolocation skills to detect mines that have been placed underwater," said Lindell, who conducted a similar experiment in a concrete parking lot. "We were unable to replicate this finding ourselves."

Lindell added: "In most cases, the dolphins succeeded in finding land mines only when we placed them directly on top of the mines."
