GAINESVILLE, FL—Although dolphins have long been celebrated for their high intelligence and for appearing to have a complex language, a team of researchers at the University of Florida reported Monday that these traits are markedly less evident on dry land.
"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."
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."
