Irish Dolphins May Have a Unique Dialect
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 Channel Dolphin and Wildlife Foundation (SDWF) has been studying a group of up to 120 bottle-nose dolphins in the River Shannon using vocalisations collected on a computer in a cow shed 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 those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both sets of dolphins—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 is an intense pulse of sound. 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.
References 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 century.
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.
The difference in eating habits between the bottle-nose dolphins and the sperm whales interested the SDWF scientists.
A．Right
B．Wrong
C．Not mentioned

Adaptation of Living ThingsCertain animals and plants develop characteristics that help them cope with their environment better than others of their kind.This natural biological process is called adaptation.Among the superior characteristics developed through adaptationare those that may help in getting food or shelter,in providing protection,and in producing and protecting the young.That results in the evolution of more and more organisms（微生物）that are better fitted to their environments.Each living thing is adapted to its way of life in a general way,but each is adapted especially to its own distinct class.A plant,for example,depends upon its roots to fix itself firmly and to absorb water and inorganic（无机的）chemicals.It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals.These are general adaptations,common to most plants.In addition,there are special adaptations that only certain kinds of plants have.Many animals have adaptations that help them escape from their enemies.Some insects are hidden by their body color or shape,and many look like a leaf or a little branch.The coats of deer are colored to mix with the surroundings.Many animals have the ability to remain completely still when an enemy is near.Organisms have a great variety of ways of adapting.They may adapt.in their structure,function,and genetics;in their development and production of the young;and in other respects.An organism may create its own environment,as do warm-blooded mammals（哺乳动物）,which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather.Usually adaptations are an advantage,but sometimes an organism is so well adapted to a particular environment that,if conditions change,it finds it difficult or impossible to readapt to the new conditions.The author cites the behavior of warm-blooded mammals in order to illustrate that______.A:a living thing may have the ability to create an environment of its ownB:a living creature may have the ability to remain still when an enemy is nearC:a living creature may have the ability to make food from its inorganic chemicalsD:a living creature may have the ability to change the color of its skin
