关于描写蓝鲸的英语作文篇一：
The largest animal on Earth is thriving anew, at least off of California. And all it took was for people to stop hunting blue whales.That's according to a new study in Marine Mammal Science.
据《海洋哺乳动物学》杂志报道：地球上动物正重新崛起，至少，在美国加州是这样的。而要实现这一目标，只需停止猎杀蓝鲸。
Today, the California group of the mighty blue whales numbers roughly 2,200, according to conservationists and based on distinctive singing. That compares with the more than 3,000 killed over the first seven decades of the 20th century. The blue whale can grow up to 30 meters in length and weigh more than 180 metric tons—and requires for food each day roughly 40 million tiny sea creatures called krill.
据自然资源保护论者及蓝鲸独特的叫声可知，如今美国加州巨形蓝鲸的种群数量约为2,200个。相比之下，20世纪前70年间，逾3,000头蓝鲸被杀。蓝鲸能一直长到30米长、180多公斤——它们每天以4000万条磷虾为食。
This may explain why the number of whales off California has stopped growing. Some conservationists had argued that individuals being hit and killed by ship traffic held back population growth. But the new research suggests it's more likely that California blue whales have reached the limits to growth in that region of the eastern Pacific Ocean.
这也许能解释为什么那些离开加州的蓝鲸没能继续繁衍生息，增大自身种群。一些自然资源保护论者曾持这样的观点：蓝鲸数量之所以没有增长，是因为遭受到海上船只的撞击和猎人们的捕杀。但新的研究认为：更有可能的原因是它们的数量已经达到了该物种在东太平洋环境容纳量的最大值。
Of course, more than 350,000 blue whales were killed in other parts of the world in the 20th century. So the species has hardly recovered to its historical abundance. But, at least in California, the blue whale is back.
当然，20世纪，除加州外，还有350,000多头蓝鲸遭受猎杀。因此，蓝鲸数量几乎没能恢复到原来那种繁荣昌盛的局面。但至少在加州，蓝鲸数量又开始增加了。
关于描写蓝鲸的英语作文篇二：
Blue whales off the California coast make calls that, sped up 10 times, sound like (sound of two-part call). The original is a wall-rattling frequency too low for us to hear.
Scientists analyzed around 2,500 of those calls, and found that the second part (sound) is nearly identical in pitch every time from each whale: 16 hertz, or four octaves below middle C. And the slight variations in frequency that do exist are only a tenth of the difference between a C and a C sharp. Those findings appear online in the Journal of the Acoustical Society of America.
The researchers don't know how many different individual whales they caught singing, or why even they sing at all. But past studies suggest only blue whale males make calls like this. So the investigators speculate that males might synchronize to a single common pitch as a sort of mating beacon.
Thanks to the Doppler effect, females swimming towards a male would hear a slightly higher pitch; swimming away, a lower-pitched moan. Serenade out of tune—you might be swimming solo tonight.
在加利福尼亚海岸边的蓝鲸们发出这样叫声，频率升高10倍后听起来像是这样子的(……滴滴滴……，呜~~呜~~~，两段蓝鲸叫声)。它们的原声由于频率太低以至于人类无法听到。
科学家们对两千五百份这样的原声进行了分析，几乎每一只蓝鲸第二部分(呜~~呜~~~)都是一样的调子：十六赫兹，比中央C低四个八度。并且最小的频率变化也仅仅只是C与升C之间频率差的十分之一。
研究者们并不知道多少不同蓝鲸的个体歌声被捕获到，也不知道为什么它们要唱歌。但是在过去的研究表明，只有雄性蓝鲸才会这样唱歌。因此科学家们推测雄性蓝鲸们也许会一致地发出同一种单一频率的叫声作为求偶的信号。
感谢多普勒效应，当雌性蓝鲸在朝着雄性蓝鲸靠近时，她们会听到稍微高一些频率的叫声;当朝着相反方向游的时候，她们会听到频率稍低的哀鸣。而那些哼着走调的小夜曲的蓝鲸绅士们——你们也许今宵无人陪伴了。
关于描写蓝鲸的英语作文篇三：
Three million years may seem like a long time. But when you consider that planet Earth is more than 4.5 billion years old, it is a pretty short period of time.
And it is over that shorter time period that the whales in our oceans today got to be so large.
The blue whale is the largest animal that has ever lived. They weigh more than even the biggest dinosaurs. They can grow to 30 meters long and weigh up to 130,000 kilograms.
Blue whales are part of the baleen whale family. Baleen is a kind of food-filtering structure in the mouths of the whales. The whales developed this system about 30 million years ago.
Other whales in the baleen family include fin whales, bowhead whales, and right whales. Today, these whales can weigh well over 70,000 kilograms.
But for millions of years, they were not nearly that large, scientists say.
"All of a sudden – ‘boom' – we see them get very big, like blue whales," scientist Nick Pyenson told the New York Times. He and other researchers recently published an article on whale size in the British research journal Proceedings of the Royal Society B.
"It's like going from whales the size of minivans to longer than two school buses," Pyenson added.
The researchers -- Pyenson, Jeremy Goldbogen and Graham Slater -- believe that a change in the Earth's climate caused whales to get so large only about 3 million years ago.
This change led to food becoming more easily available.
An oncoming ice age made the ocean water cold. High winds mixed the water in the ocean faster than before. Rain and snow made more nutrients run off from the land into the water. The nutrients resulted in algae. That attracted small fish and shrimp called krill.
The mixture of nutrients resulted in more food for large whales to eat.
Whales that were able to quickly eat a lot of food survived. And they got larger. Whales that had teeth instead of baleen, however, did not survive.
The largest baleen whales then produced other large whales.
Over the next three or four million years, the baleen whales grew 10 times bigger than they had been, the researchers say.
It is possible that the largest whales are gone, the researchers said. But, as they told the BBC, blue whales could grow even bigger -- or they could slowly die – depending on Earth's changing climate.
300万年看似时间很长，不过跟地球45亿年的年龄比起来，可谓是大巫见小巫了。
在这么短的时间内，现存于海洋中的鲸鱼体型进化得如此庞大。
蓝鲸是有史以来体型动物，它们的体重甚至超过恐龙。蓝鲸身长可达30米，体重可达130吨。
蓝鲸属于须鲸。鲸须可以过滤鲸鱼口腔内的食物。3000万年前，鲸鱼进化出这一过滤系统。
其它须鲸类鲸鱼还包括长须鲸、弓头鲸和露脊鲸。现如今，这些鲸鱼的体重远超过70吨。
然而科学家表示，数百万年前，鲸鱼并没有这么大。
科学家尼克·派森(Nick Pyenson)对《纽约时报》表示，“突然之间，它们的体型像蓝鲸一样发生了巨变。”近日，派森和其它研究人员在《英国皇家学会会刊B辑》上发表了一篇关于鲸鱼体型变化的研究。
派森进一步解释称，“鲸鱼的体型就像从一辆小货车进化为两辆校车。”
研究员派森、杰里米·葛保根( Goldbogen)和格雷厄姆·斯莱特(Graham Slater)指出，大约300万年前，地球的气候变化导致鲸鱼体型发生巨变。
这一进化使鲸鱼更容易捕食。
即将来临的冰河时代导致海水温度骤降。狂风使海水流动得更快。雨雪夹带着陆地上的营养物质流入大海。这种养分滋生了藻类，进而吸引了鱼虾。
这种混杂的养分补充了鲸鱼的食物链。
那些快速补充大量食物的鲸鱼得以存活，它们的体型也愈加庞大。而那些有牙齿但没有鲸须的鲸鱼被环境淘汰。
之后，这种须鲸繁殖出其它大型鲸鱼。
研究人员表示，接下来的300-400百万年间，须鲸的体型比原来大了10倍。
研究人员表示，这种鲸鱼有可能消失。不过正如他们对英国广播公司所说，蓝鲸是继续进化还是逐渐灭绝皆取决于地球的气候变化。
关于描写蓝鲸的英语作文篇四：
This is a good-news story about sea life. Scientists have reported that the numbers of blue whales in the eastern Pacific Ocean are the highest they have been in over a century. Researchers at the University of Washington report that there are now over 2,200 blue whales between Mexico and Alaska. Hunters killed nearly all the blue whales in that area and were close to extinction. Whaling became illegal in 1971 and the numbers of the world's largest mammal started increasing. It has taken over 40 years for the blue whale to recover. Lead researcher Dr Cole Monnahan was very happy at this positive news. He said: "For us, this is a great conservation success story."
这是一则关于海洋生物的好消息。科学家称，在太平洋东部的蓝鲸的数量是一个世纪以来最高的一次。华盛顿大学的研究人员称，目前在墨西哥与阿拉斯加州之间，蓝鲸的数量超过了2,200头。捕鲸者几乎杀死了这个海域的所有蓝鲸，蓝鲸濒临灭绝。1971年开始，捕鲸被规定为违法行为，此后，世界上哺乳动物的数量开始上升。蓝鲸的恢复花费了40余年之久。首席研究员，科尔.莫纳汉博士对这则好消息感到非常开心。他说，对我们来讲，这是一则保护生物的成功故事。
Dr Monnahan said the number of 2,200 blue whales in the area might not rise any further. He said: "Before this study, some people thought that number should be going up, but if there were about 2,200 whales to begin with, then that is what the environment can support." Monnahan warned that the creature still needs to be protected, saying: "California blue whales are recovering because we took actions to stop catches and start monitoring. If we hadn't, the population might have been pushed to near extinction." He added that: "The recovery of California blue whales from whaling demonstrates the ability of blue whale populations to rebuild under careful management and conservation measures."
莫纳汉博士称，这个海域的蓝鲸数量已达到2,200，数量很可能不会再增加了。他说，在研究开始之前，一些人认为蓝鲸的数量还会增加。但是如果一开始就有2,200头蓝鲸，那么这就是这一海域所能供养的最大限度了。莫纳汉警告说，这一生物还是需要保护的，并称，加利福尼亚州的蓝鲸数量正在恢复，正是因为我们采取措施阻止捕鲸行为，并开始监督捕鲸行为。如果我们没有这样做的话，蓝鲸很可能会濒临灭绝。他还说，捕鲸行为阻碍了蓝鲸数量的增加，加利福尼亚的蓝鲸能在这种情况下得到恢复，主要是得益于仔细的管理及其保护措施。
