Irish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they may have developed a unique dialect to communicate with each other.
The Shannon Dolphin and Wildlife Foundation (SDWF)1 has been studying a group of up to 120 bottle-nose dolphins in the River Shannon2 using vocalisations collected on a computer in a cow shed3 near the River Shannon.
As part of a research project, student Ronan Hickey digitised and analysed a total of 1,882 whistles from the Irish dolphins and those4 from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories5. Of the categories, he found most6 were used by both sets of dolphins7 -- but eight were only heard from the Irish dolphins.
"We are building up a catalogue of the different whistle types they use and trying to associate them with behaviour like foraging, resting, socialising and the communications of groups with calves," project leader Simon Berrow said. "Essentially we are building up what is like a dictionary of words they use or sounds they make."
Berrow, a marine（海洋的， 航海的） biologist（生物學）, said the dolphins' clicks（發(fā)出的卡塔聲） are used to（被用于） find（發(fā)現(xiàn)） their way around（周圍） and locate（查找...的地點，位于） prey. The whistles are communications（交流）. "They do a whole range of other sounds like barks, groans and a kind of gunshot," he said. "The gunshot （槍響聲）is an intense（強烈的） pulse of sound（脈沖聲）. Sperm whales use it to stun their prey.
"When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using it for the same reason as the sperm whales," Berrow said.
References8 in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century9.
They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boats to visit them.
本題所說的意思是鯨魚能發(fā)出比海豚更強烈的超聲波去殺死獵物。題句表達的內(nèi)容短文中找不到，故答案為 C。
6. As early as （早在）the 6th century（世紀）, Irish（愛爾蘭的） fishermen（漁夫） started（開始） raising（提高, 飼養(yǎng), 籌集 ） dolphins in the Shannon estuary（河口）.
