Dolphins Essay Research Paper Dolphins There are free essay sample

Dolphinfishs Essay, Research Paper Dolphinfishs There are many differences between Dolphins and Porpoises. Peoples might believe that the two are the same mammal, but they are non. Dolphinfishs have cone-shaped dentitions and porpoises have spade-shape dentitions. The easiest manner to state them apart is that the porpoise is smaller in size and is broader across the dorsum. Dolphinfishs are classified in the Delphinidae species and there are 30 to fifty different sorts of species in this household ( Minasian 204 ) . The Porpoises are classified under the Phoceonidae household which is Latin for pig-fish. Dolphinfishs are the smartest mammals in the ocean. Navy ships have used mahimahis to observe mines in the H2O and hunt out enemy pigboats. Dolphinfishs are really friendly mammals ; there are topographic points in Florida where one can sit the mahimahi in the H2O many dream of such a drive. This dream might non come true if people and different companies keep on killing them. We need to acknowledge the value of these mahimahis and the dangers confronting them, and acquire to halt these dangers and salvage this astonishing animal. The three chief dangers and menaces to mahimahis are pollutants, tuna boats and people. Dolphinfishs are really sacred animals to many people. When two mahimahis are in a symbol with one indicating up and the other one indicating down it symbolizes? The affaire dhonneur cosmic watercourse of involution and development? ( McIntyre 31 ) . The symbol is the manner of demoing how the mahimahi evolved and where it is traveling. The mahimahi by itself means? Allegory of Salvation inspired in the antediluvian legends which show it as the friend of adult male? ( McIntyre 31 ) . It tells the fabrication of a dolphin salvaging a adult male. The ancients believed that the mahimahi represented the critical power of the sea or H2O which symbolizes the beginning of life. The Grecian word for mahimahi is Delphys which means uterus and is known as the? populating uterus of the sea of creative activity? ( McIntyre 34 ) . Many of the Gods were based on the mahimahi because they believed it could partake in fabulous signifiers. There are many narratives about mahimahis and Gods and how they help the Gods from the sea. There are besides a batch of symbols that represent the mahimahis in small narrative blocks. This is likely why mahimahis are a signifier of good fortune or sacred to us in this century ( McIntyre 33 ) . Dolphinfishs are among a really few mammals and animate beings with the intelligence similar to our ain. Cetacean ( which is what dolphins, giants and porpoises are classified under ) encephalons are larger than human encephalons in memory and conceptual idea. There are three carnal types with comparable mental equipment ; these are worlds, elephants and blowers. Worlds are superior in the physical sense, but might be missing in the intelligence stage. Harmonizing to John Lilly: You see, what I have found after twelve old ages of work with mahimahis is that the bounds are non in them, the bounds are in us. So I had to travel off and happen out, who am I? What? s this all about? ( qtd. McIntyre 57 ) What Lilly is stating is fundamentally that the mahimahis have no bounds, they can maintain traveling and make anything for a long clip, but we limit ourselves and while we are making this the mahimahis are deriving more intelligence. The dolphin utilizations sonar like in a navy ship to observe dangers and other things in the Waterss. Sonar is a device utilizing submerged sound moving ridges for pilotage, scope determination, sensing of submersed objects, communications and etc. ( Readers Digest Dictionary 1278 ) . Since their echo sounding system gives them elaborate images of objects in the ocean, they might be able to animate sounds and undertaking images to one another. Harmonizing to Peter Warshall: Both adult male and cetaceans seem to hold a enormous capacity for digital information exchange ( information understood on the footing of its sequence in clip and infinite, like written words or the Morse Code ) utilizing fluctuations in pitch and frequence. Cetaceans may besides hold parallel communications systems which are so different from our ain that we may non be able to comprehend them. ( Analog information is information you understand because the informations itself is like what you are speaking about. For illustration, the word? loud? spoken aloud. ) It seems, excessively, that digital address is used chiefly to mention to tractable objects, while linear communicating trades with more subjective points like emotions. In this sense, it may be that Cetaceans have the ability ( utilizing their clicking setup ) to pass on digitally every bit good as analogously. ( qtd. McIntyre 58 ) What Warshall is reminding us is that the blower? s information are much more advanced than the information of a human being, possessing non merely one, but two ways to pass on. The manner the mahimahi communicates is through sound. Sound is its primary sense in the ocean. The ground mahimahis use sound is that it is excessively difficult to run at dark in murky Waterss because mahimahis are so deep the light doesn? t penetrate the H2O. Therefore, they use sound to state if it is loud or soft, fast or decelerate, high notes or low notes, short silences or long silences and many other combinations ( McIntyre 133 ) . Dolphins evolved two sorts of voice ; one is for societal communicating and the other voice is for pilotage and location. The reverberation they receive are synthesized by the encephalon into images and information ; for illustration: distance, way, velocity, form, texture, denseness and the internal construction of the object. Warshall has written about an experiment with mahimahis: A trainer taught a mahimahi to near a illuminated electric bulb. the mahimahi ever performed right but neer looked at the light bulb. The baffled trainer hid the light bulb. He turned it on and, certain plenty, the mahimahi swam towards it. The trainer figured it out: mahimahis prefer to listen-to hear the chink of the light switch-rather than look. ( qtd. McIntyre 134 ) This proves the theory that dolphins use sonar alternatively of utilizing their eyes to see. Their echo sounder is like our eyes. They can see anything and state everything that is go oning around them: Sonar is a manner of? seeing? with sound. The dolphin sends out a short chink or ping which hits a fish and bouncinesss back. The Dolphin hears the reverberation and interprets the size, texture, velocity, location, and other features of the fish from the reverberation. An reverberation can be placed between the outgoing chinks. In this instance, the dolphin interprets the returned unchanged reverberation. An reverberation can besides be placed so that it interferes with the surpassing chink. In this instance, the mahimahi must construe the sum and sort of deformation in the reverberation. ( McIntyre 134 ) Bottlenose mahimahis have been trained to use their echo sounder to state the difference between two metals and the thickness of them. Dr. Kenneth Norris did an experiment in which a mahimahi could state the difference between a half inch long gelatin capsule filled with H2O and a piece of fish the same form at 20 pess ( McIntyre 134 ) . This is utile to mahimahis because they use sonar in runing so they don? t pursuit after the incorrect quarry: A mahimahi can see item utilizing his sonar-sight by altering from low to high frequences. When sound moving ridges brush a fish with great celerity ( high frequence ) they return many more reverberations. Each reverberation provides an extra item for the mahimahi as he forms a sound image in his encephalon. ( McIntyre 135 ) This is how sound travels in H2O. Sound is energy. The manner Cetaceans create sound is by a disturbance-an explosion-by snarling the jaws shut, starting a bubble or slapping the good lucks. This compresses the H2O and the fluctuations in the perturbation makes the H2O? sound? otherwise ( McIntyre 136 ) . No 1 knows how the blowers produce their sound, but they are thinking it is the air that is recycled in the lungs merely as with people who play the saxophone and other instruments like it. Hearing in H2O for worlds is really difficult, but mahimahis, who wear? T listen through the ears, have other ways of listening. The manner they hear is through the jaw and the forehead part or melon. The sound hits the jaw and travels in a thin oil inside the lower jaw to the interior ear membranophone. The manner they hear from the melon is that sound enters the oil filled melon and base on ballss though air transitions to the interior ear membranophone ( McIntyre 138 ) . The building sounds in an oceanarium have been known to be so terrible it has killed a mahimahi in the nearby armored combat vehicle. When it rains, the noise in the out-of-door armored combat vehicles are so painful for the mahimahis they leap out of the H2O merely to get away the sounds like that the rain makes when hitting the H2O. The ground why this doesn? T affect dolphins in the ocean is because they can plunge deep plenty to avoid the horrifying sound. This is the manner the mahimahi and other mammals in t he ocean listen to one another, but it can be painful if the sound is excessively high in frequence for the mahimahi to take. Nevertheless, mahimahis are the lone animate beings on Earth that can hear such high tones and be alright with it. These astonishing mahimahis have been threatened by adult male for a long clip. Ever since the beginning of clip, worlds have tried to extinguish their challengers. First it was the Homo Neanderthalensis ; so they went on to kill most of the elephant species and other big mammals. In the present century the worlds have applied their cognition to killing off giants: The blower system appears to be a more incorporate and brooding one, evolved in conditions where immediate danger was non so likely as it was for most mammals. It is ironic that our engineering, which developed as an version to danger, has now presented the giants with dangers for which their ain evolutionary history leaves them rather unprepared. ( McIntyre 36 ) Cetaceans evolved so they could calculate out what dangers were in front, but now that engineering has kicked in, it is harder to calculate the dangers out because they are non used to the unnatural signifiers they take. There are chemicals in the H2O that kills many of the blowers members. Peoples are careless and dump pollutants and other things in the ocean that are really harmful to the species. One of the first happenings of pollutants found in the ocean was Polychlorinated Biphenyls and DDT? s. Polychlorinated Biphenyls are a really inordinate chemical found in pitch and used in lacquers and preservatives of citrous fruit fruits ( Readers Digest Dictionary 141 ) . DDT? s are a powerful insect powder which are effectual on contact ( Readers Digest Dictionary 342 ) . These pollutants were found on Britain? s seashore. John Harwood of Mammal Research Unit has done trials on a dolphin lying dead on the shore of Britain: The trials on isolated mahimahis were prompted by the find of a babe Bottlenose mahimahi, which was beached in Cardigan Bay, Wales. The babe mahimahi had more PCB? s and DDT in its tissues than animate beings from a severely polluted Wadden Sea off the Dutch seashore. ? For the degrees to be so high in an animate being so immature is really distressing, ? said John Harwood. Some dead porpoises stranded in the same topographic point besides had high concentrations of these pollutants. ( qtd. in Mackenzie 22 ) If the Waterss in Britain are this bad, no marine life will hold a opportunity to populate because the pollutants will kill them with in clip of them catching it. The manner the mahimahis get these pollutants are from the nutrient they eat. They accumulate them in their blubber and the toxic pollutants are released when the mahimahi has to populate off the blubber when it is sick, pregnant or in nerve-racking times. Hundreds of dead mahimahis were found on the Mediterranean beaches. These mahimahis were killed by a virus similar to the 1 that killed 20,000 seals in the north sea. The mahimahis died from pneumonia, because the virus destroyed the encephalons and lungs which caused their decease. Just as with an eruption among worlds, this is the mahimahis? pestilence and harmonizing to Seamus Kennedy: The eruption is the Mediterranean resurrects frights that the virus could infect all types of Marine mammals, including giants and the endangered monastic seal. ? From what we know about the behavior of morbilliviruses in tellurian mammals, they are highly deadly and spread quickly through a susceptible population. ? said Kennedy. Rinderpest, a morbilliviral disease of cowss, for illustration, can kill every animate being in a herd that has non been exposed to the virus before. ? There is no ground to believe that the virus won? T behave the same manner in Marine mammals. ? said Kennedy. ( qtd. Mackenzie 22 ) This disease is like poulet syphilis or even something worse, for this disease can kill. This disease could get down out like a common unwellness and weave up as an eruption like AIDS. This epidemic is distributing north to south from the Centre around the Balearic Sea. Approximately 50 mahimahis and other mammals have washed up on different seashore on the east side of the Atlantic ocean. ? We know that both seals and porpoises are so susceptible to these viruses. The opportunities that the monastic seals are non susceptible are so slender as to be non-existent? said Kennedy ( qtd. Dolphins in Danger ) . This epidemic has spread all the manner to the Gulf of Mexico where 33 mahimahis have washed up in Alabama and Mississippi. Kennedy states we think an epidemic is possible: ? Because we find a few animate beings positive, it means that the virus is about in a population of high susceptibleness, ? he says. He adds that there is no practical manner to hold an epidemic, and it would merely hold to fire itself out. ? If big Numberss die, at least we know in progress what? s doing it, ? ( qtd. Dolphins in Danger 13 ) The scientists know where the virus is located, but there is no manner of halting it because there is no possible manner to happen a remedy right know. The lone hope is that it merely goes off. Research workers have believed that cryptic deceases of 1000s of mammals in Europe and United States have resulted from TBT. TBT is tributyl Sn found in pigment on little boats which is used to maintain cirripeds from lodging to the hull. This is likely the most toxic substance of all time wittingly introduced to the sea ( Pearce 5 ) . The scientists believed that the porpoises picked up the compounds from the nutrient. Harmonizing to Hisato Iwata: He suspects that butyl Sn compounds may be linked to the mass deceases of several marine mammals populations in North Atlantic Waterss since the 1980 # 8217 ; s. The animate beings appeared to hold died from an epidemic morbillivirus, likely triggered by some unknown agent stamp downing their immune systems. Iwata says that immunosuppression is? one of the most representative toxicities of butyl Sn compounds. ? ( Pearce 5 ) They think that the butyl Sn may hold caused the epidemic morbillivirus which means boats are polluting the H2O and killing the mahimahis. The following biggest job is that mahimahis are being killed by cyberspaces from tuna boats. In 1992 more than a 100 dead mahimahis washed up on the seashore of Devon and Cornwell caused by angling cyberspaces. There were Markss of net rope on the mahimahi that suggested this scenario. In Britain the one hundred and 18 mahimahis were the most mammals killed in their records. The vets searched for what happen: They looked for marks of the extremely infective morbillivirus that killed 10s of 1000s of seals in the north sea in the late 1980 # 8217 ; s, and subsequently caused the deceases of 100s of stripped mahimahis in the Mediterranean. They did non happen any. Nor was there any suggestion that the mahimahis had suffered from a parasitic disease or pollution. ( Bonner 6 ) This is how they came to the decision it had to be cyberspaces because the mahimahis didn? T dice from any disease, but had Markss on them. The scientists so put two and two together and they figured out it was the cyberspaces. This besides tells them that the mahimahis were fundamentally murdered by fisherman merely so they could acquire their fish. Thirty to thirty-eight of the mahimahis examined had bad Markss around the beak and flipper countries. They besides had other Markss that told the testers that they were caught up in cyberspaces. A twosome of mahimahis had lost their fins and other parts because the fisherman had to break up the parts to acquire the mahimahis free from the web: The mahimahis died all of a sudden, with fish still undigested in their tummies. The species of fish, chiefly mackerel and sardine, and the narrow mesh of the cyberspaces Markss, suggest that they were caught by bag seiners or brace trawlers, big boats which ran a net between them up to a kilometer apart. ( Bonner 6 ) The fisherman didn? T attention what got caught up because they could hold shortened the net and watched where they dropped, but they merely cared about one thing and that was catching the fish. Dolphinfishs killed by tuna fleets are expected to be less than five 1000s in 1993. In 1992 15,470 died in cyberspaces ( Marine Conservation News 22 ) . This is a immense addition and no 1 cared ; they merely wanted to do money. Six old ages ago when a heart-breaking picture of a mahimahi threshing in the cyberspace of a Panamanian tuna boat was flashed across the telecasting screens around the universe, the solution for one time seemed blessedly simple: Ban the fishing cogwheel and patterns that enmesh the sleek, endearing mammals along with yellowfin tuna. Congress and the nutrient companies reacted fleetly. With in a twosome of old ages, the U.S. tuna market was basically closed to all but? dolphin safe? fish. ( Carpenter 71 ) This narrative is why tuna companies should halt fishing with cyberspaces and dragging them all over the H2O and possibly happen a different manner to catch their tuna. Finally, the authorities came through, but it was still late because another mahimahi had died a atrocious decease. Five old ages ago the Eastern Pacific was a sidesplitting field for mahimahis. Over the past 35 old ages six million blowers were killed from the tuna boat? s cyberspaces. The mahimahis were caught in the cyberspaces because tuna swim right underneath the mahimahis and this is how the mahimahis get captured. Tuna boat captains now have particular orders and hopefully this might work: Before a net is hauled in the captain backs up the boat, leting one terminal of the net to dunk below the sea surface opening up a flight channel for at bay mahimahis. Skippers besides use a particular cyberspace with a panel of all right webbing to forestall mahimahis from snagging their beaks and submerging. Furthermore, each tuna boat is granted an one-year mahimahi putting to death quota. If a skipper exceeds his bound, he must halt fishing on mahimahis for the twelvemonth, and the surplus is deducted from his allocation for the following twelvemonth. ( Carpenter 72 ) This is a good technique, but they shouldn? T kill any mahimahis. The new quota should read: if they kill one mahimahi they will lose their yachting licence and be fined to a great extent. With the safe cyberspaces, they should hold no job maintaining mahimahis alive. The authorities should besides merely allow a certain sum of boats to tuna Hunt and they should all be professional? s. That manner we will hold no dolphin violent death. Tuna boats have tried several methods of maintaining mahimahis off from cyberspaces. The first method is by bombing and the 2nd is utilizing bogus fish. The bombing process works like this. First they find a school of mahimahis and so a chopper or velocity boat drops a seal bomb to disorient the mahimahis. This method allows the fisherman to sack both mahimahis and tuna and one time they are caught up the fisherman bead another bomb to trail the mahimahis out the other terminal of the cyberspace. However, conservationists say? the mahimahis get caught up in the cyberspaces still. ? ( Anderson 19 ) Congress eventually has done something right: In the late 1988, the U.S. Congress banned the usage of explosives more powerful so seal bombs, which were exempted from the statute law pending farther surveies. Last November, the national piscary service concluded that no explosives should be detonated within one and a half pess of the mahimahis ( Anderson 19 ) . The Fisheries Service stepped in and told the boats what to make because the authorities was excessively frightened. The other method plants like this. The fictile devices reflect the mahimahi? s echo sounder signals and halt them from swimming into the cyberspaces: Dolphinfishs and porpoises eatage for nutrient with the aid of echo sounder. Like chiropterans, they send out sound moving ridges and do sense of their environment beyond the scope of their sight from the reverberation they have back. ? It? s as if the animate being has a limelight on top of its caput, a spot like a mineworker? s lamp. ? says David Goodson. , but fishing cyberspaces are excessively all right to reflect the echo sounder. ? Basically, the cyberspace is acoustically unseeable to the mahimahis. ( Coghlan 18 ) If they can happen a manner to do the cyberspaces sonar built, so the mahimahis will maneuver off from them and there will be no dead mahimahis. The design of the experiment is a lightweight ball: ? The curvature of the interior surface is critical and must be precisely right to give the needed contemplation from any angle approached? ( Coghlan 18 ) . The mahimahis are supposed to swim over the cyberspaces, but alternatively they swam around them and so after it was clear they went back to the original class after they bombarded it with echo sounder. Goodson says? a much larger scale trial is now required to optimise the contemplation design and spacing ( Coghlan 18 ) . The lone clasp back for this undertaking is the money needed for the research and without farther support this thought will neglect. Worlds have straight caused some of the mahimahi? s deceases excessively. The humans entirely have done this without any arms, chemicals or cyberspaces. Harmonizing to C.A.L.M ( Department of Conservation and Land Management ) : Young mahimahis at Monkey Mia in Western Australia are deceasing because their female parents have become dependent on nutrient handed out by park Texas Rangers to entertain tourers. The Dolphinfishs nursing from manus fed females, are malnourished and vulnerable to disease and assail by marauders. ( Anderson 5 ) The Texas Rangers are killing the mahimahis and the tourers think it is fun. If the mahimahis become weak so they will decease from sharks and other enemies because they are so weak they can non contend back. In 1975 tourers were feeding four female mahimahis and merely two of these mahimahis are still alive. The females produced 17 progeny and merely five remain. The mortality rate was 70 per centum since 1986 ( Anderson 5 ) Even sometimes mahimahis kill their ain sort. Nineteen healthy mahimahis were stranded on the beach and died because they followed their leader. Every one of the mahimahis were healthy except the male leader, the 1 they followed. Paul Jepsen says? Sick blowers frequently beach themselves? ( qtd. Anderson 5 ) . This is merely like a cult making what of all time the leader does. Harmonizing to Jepsen: There are three theories about why groups of mahimahis become stranded on beaches, he says. ? It may be through disease, or because they chase fish inshore or because of some kind of navigational mistake # 8211 ; possibly because their reverberation sounding systems do non descry gently postponing beaches. ? The necropsies showed that none of the mahimahis had been eating fish instantly before they die. ( qtd. Anderson 5 ) This is the mistake of the mahimahis, even though they are supposed to be the smartest mammal so why are they making this to themselves. After all the violent death of mahimahis by tuna boats, the authorities has eventually made some regulations against these fishermen. Tuna companies have agreed that? they will no longer sell tuna caught by methods harmful to mahimahis? ( ? Tuna w/o Guilt? 63 ) . The companies will set out a label on all tins that will state? Dolphin Safe. ? Harmonizing to Senator Joseph Biden: The Tuna company will set a DOLPHIN SAFE logo on its tins, and may hold to bear down? a twosome of cents more? to account for higher costs, O? Reilly said. The dolphin-free promise was matched on the same twenty-four hours by the other two major canners, Bumble Bee Seafood and Van Camp Seafood which sells Chicken of the Sea trade name. Environmentalists responded with hilarity. ? It was an incredibly responsible action. ( ? Tuna w/o Guilt? 63 ) The canners have agreed as good that? They will no longer accept tuna caught in the part, unless it has been harvested without salvaging the mahimahis as good? ( ? Tuna w/o Guilt? 63 ) . When they had announced that the tuna fish would be made dolphin free, they said? It symbolized the victory of ecological values that non merely can non be measured in dollars and cents, but have no obvious human benefit at all, this 1s for the mahimahis? ( ? Swim With the Dolphins? 76 ) . Heinz made the first move to guarantee tuna fish to be dolphin safe. Following them were other companies. Heinz did this in concern for clients and in taking this measure, it received station cards and letters from concerned school kids. Ted Smyth says: ? Hopefully in a few old ages the safest topographic point for tuna will be swimming underneath a dolphins. ? ( ? Swim With the Dolphins? 76 ) If a jurisprudence is passed that tuna boats can non sack around mahimahis so tuna will non hold anything to worry approximately because they swim with the mahimahis and no 1 will be able to acquire to them. Health experts urge Americans to populate longer by eating more fish, but conservationists warn that sacking tuna had already killed 80,000 mahimahis. There is concern for this because they are the most intelligent animal next to worlds. Now the tuna boats sail behind the streamer? We Love Dolphins. ? The job is that tuna love dolphins excessively, and love to swim with them. When the boats throw the cyberspaces around the mahimahis, they merely hope to happen tuna below, non recognizing the danger they are doing to other animals besides the mahimahi: Dolphinfishs are non yet wholly safe. Giant fishing vass towing 30-miles-ling impetus cyberspaces strip mine the sea of both mammals and fish. Their effectivity is so complete that The United Nations has called for an terminal to their usage. And so there? s pollution. When half the Bottlenose mahimahi population on the U.S. middle Atlantic seashore died, the authorities suspected a natural ruddy tide was to fault. But many scientists wondered whether PCB? s found in the dead animals, frequently at degrees fifty times higher so the degrees allowed in fish, had weakened them foremost. ( ? Dolphins Get a New Reason? 14 ) Finally the authorities understands that the cyberspaces are really unsafe to the mahimahis and other blowers in the ocean. Now what the mahimahis have to worry approximately is PCB? s, and if they get attacked by anything so they will be defenceless because they will be so weak. Another job the mahimahis have to face is imprisonment: ? Heartss are won over when these marine mammals perform, but many critics believed that it is barbarous to maintain them in imprisonment? ( Riley 58 ) . Laws were passed in South Carolina censoring any public show of confined mahimahis and giants and in Australia their gaining control and show has been ban since 1988. The Miami Dolphins football squad has a mahimahi that is in a armored combat vehicle so it can execute for the fans during halftime. Lawsuits were filed against New England Aquarium over intervention of the mahimahis. Whatever the hereafter holds, the particular relationship that has existed between the mahimahis and worlds since the clip of Homer will go on. Even Scientists trained to detect life with rigorous objectiveness, acknowledge the human impulse to happen? a kindred spirit? in mahimahis. O? Barry learned that felicity in life is the journey itself, non some topographic point you arrive at. Dolphins live that manner every twenty-four hours. ( Riley 67 ) Dolphinfishs and adult male have ever been close and will be like this for old ages to come. Dolphinfishs live life in felicity because they don? T recognize the danger people cause them. Dolphinfishs are intriguing animals which people already know, but now people are understanding them better. We have lost a batch of mahimahis over many of old ages and hopefully people, angling boats, and chemical workss will watch what they are making because they are destructing a species that one twenty-four hours could salvage our lives and be a valuable beginning. Look at what the mahimahis did for the naval forces during wartime. They helped steer the ships through mine Fieldss and spotted the enemies ships and other things to assist the U.S. in the war. Possibly Congress or even the president will go through a jurisprudence that prohibits tuna boat angling unless they can come up with a manner non to kill or ache the mahimahis. There are still many dangers out in the ocean that are killing mahimahis and hopefully in the hereafter we will be able to happen them all and bring around them so non another individual mahimahi will decease. Remember mahimahis are mammals and they are really near to us so we should protect them as we protect our ain species. Anderson, Ian. ? Dolphins Pay a High Price. ? New Scientist 15 Oct. 1994: 5.
