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. According to study researchers, a group of 25 bottlenose dolphins removed from their holding tanks failed 11 exercises designed to test their basic cognitive abilities and reasoning skills. “The dolphins were incapable of recognizing and repeating simple gestures,” said study co-author Dr. Scott Lindell. “Their non-verbal communications were limited to a rapid constriction and expansion of the blowhole, various incomprehensible fin motions, and heavy tremors while they lay prone on the lab table.” After capturing the dolphins from the ocean, Lindell and his colleagues tagged them and placed them under the intense, high-wattage lights of a moisture-proof lab. The researchers then administered an extensive battery of tests designed to measure ever...
