WASHINGTON - Dolphins have the ability to call each other by their names, claims a new study. Researchers say that the bottlenose dolphins are the only animals beside humans who can use sounds to alert their friends as to exactly who they are. "We captured wild dolphins using nets when they came near the shore," said lead researcher Vincent Janik, of the Sea Mammal Unit at St Andrews University in Scotland. "Then in the shallow water we recorded their whistles before synthesizing them on a computer so that we had a computer voice of a dolphin." He added that the researchers played back the sounds to the dolphins and the mammals responded, "We played it back to the dolphins and we found they responded," he said. "This showed us that the dolphins know each other's signature whistle, instead of just the voice." These findings seem to suggest that dolphins might be closer to humans
in their make up than previously thought. "I think it is a very exciting
discovery because it means that these animals have evolved the same abilities
as humans," Janik agreed. "Now we know they have labels for
each other, like we do." "Each animal develops an individually distinctive signature whistle in the first few months of its life, which appears to be used in individual recognition," Janik said. The researchers studied the dolphins in Sarasota Bay, Florida. These dolphins have been observed for close to 30 years. Study co-author Laela Sayigh said that it was too early to tell that dolphins were skilled in language, I tend to shy away from using the word 'language' myself, because it's such a loaded term, she said. I still really feel strongly that there is no evidence for something like our language. (Dolphins) have got the cognitive skills at least to have referential signals.
Navy divers inspect Oriskany site PENSACOLA, Fla. - Anxious divers got their first look at the USS Oriskany Thursday, reporting that the ship landed in an upright position facing north to south when the Navy used explosives to sink the massive aircraft carrier a day earlier. The Navy said the Oriskany's flight deck was positioned at a depth of 150 feet as the ship settled into the sand. The depth of the flight deck is important because the maximum depth for recreation sport divers is about 132 feet, said Eilene Beard, a dive shop owner and Pensacola native who donated $25,000 in retirement savings to help the community promote the Oriskany project. The first official reports of the 150-foot depth of the flight deck were a disappointment to Beard. "The maximum sport diving depth is 132 feet and we'd hoped it wouldn't go below that, but there will be plenty of superstructure along the wheel house for sport divers," Beard said. Divers who go beyond the 132-foot depth must be qualified in technical diving and breathe a combination of gases to reach the extended depths, she said. "Oh it looks like that's going to be a fun dive. She's going to hold so many fish in all those nooks and crannies," said shop employee Paul Sjordal. The Navy sunk the massive Korean and Vietnam era aircraft carrier Wednesday morning 24 miles off the coast of Pensacola as a flotilla of boats filled with hundreds of Oriskany veterans watched. Many saluted as the Oriskany dipped below the ocean. The ship, known as the "Mighty O" was the first warship sunk under a pilot program to dispose of old Navy vessels through reefing. The $20 million sinking was delayed for nearly two years by hurricanes and environmental permitting problems. The Oriskany, commissioned in 1950 and named after an American Revolutionary War battle, saw duty during the Korean War and was home to John McCain when the Navy pilot and future senator served in Vietnam. It was also among the ships used by President Kennedy in a show of force during the 1962 Cuban missile crisis. It was decommissioned in 1976. Pensacola leaders hope the sinking will provide an economic infusion by luring sport divers and fishermen. Phones rang nonstop at the MBT dive shop Thursday afternoon with customers who wanted to book trips to the Oriskany dive site. The site was expected to be opened for recreational diving Friday afternoon.
