1.C. 细节题。 利用问题句中的细节信息词bottle-nose dolphins， sperm whales, eating habits和特征词SDWF(香农海豚与野生动物基金会) scientists共同作为答案线索，在文章中查找答案相关句：
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 (一直在研究)a group of(一组) up to (多达，直到)120 bottle-nose dolphins (宽吻海豚)in the River Shannon using vocalisations (发声)collected on a computer (被收集在计算机里)in a cowshed (牛棚) 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 biologist, said the dolphins' clicks are used to find their way around and locate prey. The whistles are communications. "They do a whole range of other sounds like barks, groans and a kind of gunshot," he said. "The gunshot(射击， 枪响) is an intense(强烈的) pulse of sound(脉冲声). Sperm whales use it to stun(使晕倒) their prey(猎物).
"When I first heard(听到) it I was surprised (感到吃惊)as I thought (认为)sperm whales (巨头鲸)were the only species(物种) who used it. We can speculate(推测) the dolphins(海豚) are using it for the same reason (为了与...同样的原因)as the sperm whales(巨头鲸)," 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.
