海洋生物的英语作文【精品19篇】

On Sunday, my mother and I went to the Ocean Park to play.

As soon as I entered, I saw two beluga whales. They had bright black eyes and were white, plump and lovely. The shark has two rows of sharp teeth. Its frightening. There are all kinds of jellyfish with colorful lights. The turtle in the pond is so big that I can sleep on it as a bed.

The sea lions performance is particularly wonderful, some dances, some heading balls, and some hula hoops, especially cute.

Ocean Park is really fun, I am very unforgettable now!

星期天，我和妈妈去海洋公园玩。

刚进去就看见两头白鲸，它们拥有着一双亮晶晶的黑眼睛，全身白白胖胖的，真可爱。鲨鱼有两排锋利的牙齿真吓人，还有照着七彩灯光的各种水母，水池里的大海龟大得不得了，我都可以把它当作床，在上面睡觉了。

海狮的表演特别精彩，有的跳舞，有的顶球，还有的转呼啦圈，特别的可爱。

海洋公园真的是太好玩了，令我现在都很难忘！

“嘿！沈雨恬，听说海洋公园搬来了，参观海洋生物展。”哥哥一进门就兴奋地对我说。“真的吗？”我惊奇地问。哥哥就把他手里的广告单给我看。我一看，嗬！上面写着几个大字“海洋公园搬家了”下面还有日期：十月一日——十月三日。“还有三天。”我自言自语地说。太好了，我一定要去看看。

十月三日，因台风延期的海洋生物展好不容易展出了！我和妈妈以及刘老师、孙婧她们来到了目的地——灯光球场。一路上我就像一只急不可待的兔子，蹦蹦跳跳的，小学三年级作文《参观海洋生物展》。买了票一进去，我就看到了各种各样五彩斑斓的贝壳，看得我眼花缭乱，不知看哪个好。有一个水字螺特别奇怪。它的棱角有六个。一边是两个角往上弯，最后一个角是往下弯。另一边却都是往下弯的。我还在贝壳展里看到了红铁树，红铁树还开花呢。粉红色的花瓣，黄黄的花蕊，可漂亮了。

孙婧拉着我和妈妈去看蝴蝶展。蝴蝶展旁边有鲨鱼展，我不想看那凶猛的海中霸王，蹲在美丽的蝴蝶面前舍不得走了。每一只蝴蝶都好看，我真是想不通：那么恶心的蛹怎么能变出这么美丽可爱的蝴蝶呢？我最喜欢霸王蝶了，因为它又大又美，有我的头那么大呢！

后来我们又来到了珊瑚展区，看到了好多种珊瑚虫，它们都是活的呢。珊瑚有很多种颜色，很鲜艳。其中有一种是半透明的白色，顶端还有一点点粉红色的小东西，我们都猜这是一个个小嘴巴。

我们还看了美丽的海底杀手——水母，海中的老寿星——海龟……今天真让人大开眼界，全部看完，我们才恋恋不舍地回家了。

对于人类而言，大2113海是辽阔无垠和刚猛5261无比的，但是如果放置4102在更广阔的空间内，它同样也是渺小和脆弱的。《海1653洋》先从一个孩子的视觉去感受大海之大，然后又从一只海鬣蜥的独特视觉去看人类文明对海洋生物的影响，并把地球和海洋引向了更加浩瀚无垠的宇宙，在一瞬间大海变得微不足道。在人类已探知的宇宙范围之内，唯一能孕育生命的就是地球这颗蓝色的星球，而海洋则是地球生命的起源之地。然而在广阔的宇宙中，地球不过是空气中的一粒微尘，鲜活而渺小，海洋就是这个生命体的血脉。

这一大一小的对比，揭示了生命的伟大渺小并存的富于思辨性的二元对立，同时也昭示了越是渺小越值得珍惜的哲理思维。大海之小又是具体而微的。海洋中那些色彩斑斓的生命在镜头下蹁跹起舞，互相竞争，述说着生命之强和生命之美。《海洋》通过诗化的镜头和优美的配乐，为我们展示了大海中各种美丽的生命形态，大到鲸鱼，小到微生物，从海滨天空到洋底深处，从南极到北极，各种生命形态既有合作也有竞争，合作演示着自然的奇迹，竞争彰显着进化的艰难。奇妙之处，令人意趣盎然，艰难之处让人心生感动。从大到小，从小复大，《海洋》已把生命和自然述说的唯美而动人。

The Marine life environment is a complex system including seawater, sea water content and suspension, seabed sediment and Marine life.The abundant biological resources, mineral resources, chemical resources and power resources of the sea are the indispensable resources of human beings, which are closely related to the survival and development of human beings.

The main objective of Marine conservation is to protect Marine life resources so that they are not depleted for sustainable use.Special priority should be given to protecting Marine life that is valuable and endangered.According to the relevant departments of the investigation, due to overfishing, accidental killing of non-target to allow hunting of Marine, coastal tidal flats in the engineering construction, mangrove deforestation, widespread Marine pollution, at least 25 in the worlds most valuable fisheries resources exhausted, whales, turtles, manatees and many other Marine animals are in danger of extinction.With the expansion of Marine development, the potential for greater damage to Marine biological resources is expected.

Marine conservation of the first task to stop the excessive use of Marine biological resources, secondly we must protect Marine habitats or niches, especially their migratory, spawning, feeding, avoiding DiHai coast, beaches, estuaries, coral reefs, to prevent the heavy metals and pesticides, oil, organic matter and eutrophication of nutrients, such as pollution of the sea.To maintain the renewable capacity of Marine biological resources and the natural purification capacity of seawater, maintain the balance of Marine ecology and ensure the sustainable development and utilization of the sea.

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天，大姨带我去大梅沙看大海，因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮，我觉得大海应该是这样的：碧蓝的海水，浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树，海边静静的躺着许多贝壳，海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空，天空上的一轮红日，海欧飞来飞去，这景象多美呀！多令人陶醉呀！我心情轻松愉快。

可当我才看见大海的一瞬间，我失望了，心情一下子变的沉重了。因为我眼前的大海是灰暗的，是浑浊的，是没有生气的，是没有自信的。有的只是自卑。我知道大海原来不是这样的，而是被人们污染成这样的。

现在，人类为了生活，大量砍伐树木，砍了又不栽，以前有多少热带雨林，现在是平地，以前多少树木，现在取而代之的是高楼大厦。工厂排放的废气，污染空气，又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水，让水里的小鱼，小虾都被毒死了，河面上浮着发臭的鱼的尸体和垃圾，这一切又是多么的可怕呀！

让我们去拥抱大自然吧！去保护大自然吧！让世界上的一切都变得美好。

我们生活在地球上，那里有郁郁苍苍的树木；有五颜六色的花朵；有奇峰罗列的山峰……地球真是丰富多彩，陆地上生活着许多生物，海洋也不例外。看了电影《蓝色星球二》使我大开眼界。

海洋占地球面积的97%，听了这个数字让使我大吃一惊。波涛汹涌的大海一直不休息，卷起巨大的浪花。宽吻海豚成群结队的在浪花旁边嬉戏。伪虎鲸和虎鲸是老朋友，他们在海面快乐地玩耍。

猪齿鱼在浅海处生活，它们的食物十分奇特——贝壳里的肉。座头鲸体型庞大，在海面无忧无虑地生活。在北极地区因人类的影响，气候变暖冰雪融化，海象们患难与共，一不留意，就会变成北极熊口中的美食。

海底变化莫测，海上也热闹非凡，父母们带着雏鸟在“训练场”上练习飞翔。因为刚学会飞的雏鸟，不能长时间飞行。一旦失去力量和平衡，就会坠入海中。珍鱼参在海里看见海面上有雏鸟，就会上来吃掉，难以置信的是：珍鱼参可以精准地计算出，正在捕捉的鸟儿的速度。

大海奥秘无穷，通过这次观影，我懂得了前所未知海洋知识。从电影里感受到了大海的丰富多彩，激起了我探索大海的决心！还打开了我的视野，它无边无际，流淌着快乐！大海为地球卷起巨大的、快乐的浪花……

The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.

Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.

Many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.In fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.

Water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.All these factors make our water unsafe to drink.

前几天，学校组织我们去紫光影院看了一部电影——《海洋》，它拍得很美，但看着看着我却哭了。海洋实在是太美了!海里有珊瑚，它们色彩斑斓，有的是粉的，有的是红色的，还有的是白的，这些都是我从未见过的。它们在海水中一会儿张开，一会儿合拢，像是在说悄悄话，其实它们是在捕食，真是神秘极了!

海里的动物那么自由自在，快乐无比。海豚、海豹、鲨鱼、海牛、鲸……如果你到了海底，你会发现那儿的生物是那么丰富多彩，五彩缤纷!乌贼最可爱了，它喷出海水能让自己一下窜出很远。海豚就像一个跳水健将，迅速的跳来跳去。原来海里每天都上演着“争夺战”，螃蟹和龙虾开始了争夺地盘的战争，龙虾生气了，把螃蟹的一只大螯硬生生地给扯下来了，真是弱肉强食的海底世界啊!可是人类一点却也不珍惜这个美丽的海洋世界，当人类认为自己征服了海洋，就开始大规模地进行捕杀。从二十世纪到现在，蓝鲸从二十五万只下降到七百多只。在电影中，我看到人类把一只鲨鱼的鳍割光了，又把它扔到海里。它沉到海底还活着，两腮往外流着血，嘴巴一张一合，仿佛在诉说自己的悲惨遭遇。血水染红了海水，一片片晕染开……此时此刻，我的心突然被刺痛了，有种无法言语的感受。我的眼睛不知不觉的湿润了，影片渐渐变得模糊，我再也看不下去了，原来人类竟是如此的残忍……

在一个世纪以前，大海中有数不清的鲸和海豚，但是现在许多海域已经看不到它们的踪迹了。人类呀，海洋在向你们发出哀求，你们听到了吗!为什么我们不能爱护我们的星球，爱护这个星球上的一切动物呢?海洋世界是美丽的，也是珍稀的，为什么我们就不能来保护它呢?

Boundless sea to look forward to, give people the beauty, give a person

warm motherly love.

The sea is like a poem; it jumps; like a picture, rich in meaning; and like

a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes

filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea

is blue world, is also the cradle of life. Pregnant with many free and small

life. The sea is so mysterious, so charming!

Now the sea has changed. The sea is no longer clear, it becomes muddy and

dirty. Washed up on the beach, left is no longer alive and kicking the fish

shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish

shrimp, stinking. Why is that? Its all because of us. When people admire the

beauty of the seaside, they throw the foul rubbish into the sea. There are also

people living on the beach, the toilet drain pipe to the bottom of the sea.

Whats worse is that the factory waste water flows into the sea in large stocks,

and the sea is dyed in a strange color. Led to the birth of a lot of lack of

brains, low IQ infants, our next generation - bright eyes [voice tender], the

face of the next generation of red, will never see the beautiful blue sea.

Someone once did an experiment. He compared a basin of water to the ocean,

and dropped a drop of ink into the sea. Immediately, the ink slowly spread out,

became shallow and disappeared. The sea water was almost as clean as ever. If

the ink kept dropping, the color of the sea would be deeper and darker, and

eventually it would become a basin of black water. 6 billion people on the earth

produce large quantities of living waste water and industrial pollution every

day. Like ink, it has been injected into the clear sea water. It has become a

polluted lake.

To the health of our human beings, to see the beautiful blue sea for our

children and grandchildren. Let us act now, love the ocean as much as we love

life, and love the common blue home of mankind.

“呼，呼！呀!”一觉醒来，我睁眼一看，枕头像棉花山，小床变得像一个足球场那么大，我实在不敢相信自己的眼睛，心里在嘀咕：“天哪，真壮观，这些东西怎么都变得这么大了，如果不是它们变大了，那就是我变小了……”我脑子里冒出一个又一个奇怪的想法，奇妙的梦作文。“我脑子进水了?眼睛出问题了?还是中了魔法了？我百思不得其解，只好爬到了“棉花山”上，眺望着四周，眼前的景象更让我吃惊:我的鞋子比大口袋还大，衣服看起来有1亿个我这么大。“no”我怎样去穿衣服啊！没办法只有借用一下芭比娃娃的裙子了、没想到的是，芭比娃娃的衣服我竟然穿起来刚刚好，而且十分的暖和。我不禁笑了笑!

“肚子太饿了”!可怜的我知道顺着床单滑下去，一路连滚带爬的到了桌子上，小学五年级作文《奇妙的梦作文》。“哇”！早餐可真丰富啊，像小河的牛奶，像高山的烧卖，连饼干都有飞机场那么大了，真是应有尽有，五花八门，眼花缭乱啊！这些好吃的够 我吃一辈子了

脸刷牙了。我费了九牛二虎之力才爬到脸盆上，又发现水龙头没关紧，聪明的我赶忙借了一滴水抹抹脸，有借了一滴水簌簌口。便随手抽出一张餐巾纸，把纸张四个角抓好“嗖”的一下，已由这边脸盘上落到那边地板上，接着我从卫生间门缝中轻而易举的钻了出来，又轻而易举的的钻进了老爸的卧室。

我拼命的捂住耳朵，怕被老爸的呼噜声吓死，没想到的是，我真的要被吓死了，我一头撞到了闹钟。“叮叮叮….”闹钟叫个不停，老爸也被我吵醒了，被他发现原来是我搞的鬼。肯定要揍我了，我乱成一团，气喘如牛，却又叫不出声来……

忽然我变高大了，啊，原来我是在做梦！总算能松口气了，我再也不想变小了！

In the vast ocean live many creatures with great intellectual and physical capacities.Dolphin is one of those great creatures,whose capacities to think and move at an astounding rate puzzle those who study their behaviors,Dolphins possess something that makes them different from all the other sea creatures.It is not strength or speed but the size of their brains.Dolphin s brain is almost the same size as that found in the human head.They live for a ling time.

Dolphins babies are born in the water.They can grow up to three and a half meters long.

Dolopins use sound to help them find their way,look for their food and talk with each other.Sound is just like their eyes and mouths.

海洋是我非常向往的地方。小学的时候我曾读过一本书，叫《奇妙的海洋生物世界》，就已经对海洋和海洋生物充满好奇。因此，我非常期待这次名师讲坛，非常期待学到更多的海洋知识。

果然，这是一场妙趣横生的讲座。冷向军教授从大家最感兴趣的宇宙大爆炸开始讲起，他告诉我们地球上首先出现的是远古的海洋，之后才有陆地。他还说，最先出现的物质也不是陆地上的，而是在海洋中诞生的。冷教授的这番话，完全颠覆了我从小到大形成的观念，原来海洋是这么神奇啊!

冷教授详细介绍了生命的起源，他说：生物的形成经历了很多阶段，从无机小分子物质开始，到有机小分子物质，再到有机高分子(大分子)物质，然后形成多分子体质，并在最终形成了原始生命。这个过程都是在原始海洋中实现的。冷教授还比喻说，如果地球的出现算作一天的话，那么人类出现在这一天的最后1分31秒。而根据冷教授的推论，1秒等于5000年，也就是人类已经有400万年的历史啦。

终于，冷教授的讲座迎来最振奋人心的时刻。原来，海洋生物包括海洋动物，海洋植物，微生物等。而海洋动物又分为有脊椎动物和无脊椎动物，有脊椎动物主要是鱼类，以及鲸鱼等大型海洋动物。他还重点介绍了我们生活中见到最多的鱼类。鱼分为海水鱼和淡水鱼，全世界有2.8万种鱼，其中海水鱼就有1.6万种……冷教授用生动的语言给我们传授了大量的海洋和海洋生物知识，让我们受益匪浅。他甚至还教我们怎么辨别鱿鱼、章鱼、乌贼的方法呢。

讲座的最后，冷教授讲了捕鱼和海洋污染的知识。中国是捕鱼最多的国家，同时也是养鱼最强和护鲸最有力的国家。但是，全球到处都在污染海洋，特别是石油和塑料。冷教授给我们看了几张图，上面都是因为石油黏附导致无法飞翔而在等死的海鸟，都是吃了塑料而致死的海洋生物，令人心痛。因为此，我甚至想起了不久前在SSP上看到的一篇文章—Saving

Sea Life，对那篇有了更深刻的理解。

不知不觉讲座就结束了，但是我和我的同学们都觉得意犹未尽。我们在了解了海洋和海洋生物的同时，也知道了海洋污染的严重。我们既有获取大量知识的喜悦，又为海洋污染感到痛心。我们发出呼吁：保护环境，保护海洋，救救那些可怜的海洋生物吧!

最近，同学们都在养一种花花绿绿的东西，听说他的官名叫海洋生物球――一棵棵彩色的软软的小球。它还能长大、繁殖呢！我也买了一袋，拿回家养了起来。

我拿出一个空饮料瓶，用水冲洗干净后，把一棵棵绿色的柔软的小球放了进去，再到入一些凉白开水，就大功告成了。

我高兴地捧着它，只见瓶子里的小不点儿不停地游动散发出绿色的波纹。过了不大一会儿，那绿色融入水中。小不点儿变成透明的了。在这绿色的水中，它门生活得舒服吗？它们可以长大吗？我便赶忙去换水。

从此以后，我经常给小不点儿换水。果然，一个星期后，小不点儿‘的数量从十八颗变成了三十颗，它们果然繁殖了，一周的时间竟比原来多了十二颗！我不由得欢呼起来，水换得更勤快了。

前不久，我们学了《宇宙生命之谜》这一课，让我知道了生命所以能够存活，必须有一个适于生存的环境。有一点很重要，那就是必须有空气。

我猛然想起了我的海洋生物球，瓶子里没有空气，它们能活下来吗？

放学后，我急忙跑回家。看我的小不点儿死了没有。可它们十分顽强，静静地沉在水底我沉默了，也许它们不是什么海洋生物球，而是小摊主赚钱的橡胶球吧？

All things cannot be separated from water, and fish cannot leave water.The theme is: water, the root of all things.

It is true that the seven parts of the sea are right. We are from one of the creatures in the sea, and we have the same gills of fish when we are young...Everything shows that we are connected to the sea.

Maybe we were just a little fish, but now we are the greatest humans.

The sea is so kind and mysterious, what is it that we humans are, the most intelligent creatures at the top, what are our ancestors?Its a low-grade fish or an advanced dinosaur, and everything is a mystery.

Now the sea is being developed by us, the sea ranch, the Marine oil base is so amazing.The sea gave us life, and gave us so much energy, and we?Marine oil base causes large oil spill, resulting in Marine oil pollution!What are we doing with the indiscriminate killing of whales and the salivating of shark fins?Is the environmental protection or the destruction of the ecological balance?

If the sea could wash everyones heart like a shell, there would be no creatures in the world because of our indiscriminate killing.Is it a reward that the sea is our mother, and it has created the destruction of all that it has created?No, it isnt.What else can we do when black oil covers the ocean, and when black exhaust fills the sky?The sea belongs to nature, nature belongs to us?We belong to the sea, and the sea belong to us?

What are we doing here?To kill for personal gain?Destroy for yourself?No, no, no.I do not believe that we will destroy our oceans, and I do not believe that people will despair when the oceans disappear.Because everyone is selfish.

Is it humane that the oceans have created us and destroyed us?

Although were trying to protect the environment, its too late, unless time goes backwards, unless theres a miracle, unless its all over again.I believe we can get the ocean back to our youth, and we are the smartest intelligent creatures.

Everyone, for the sake of the bright future of the sea, also protect the sea for ourselves.thank you

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

Ocean refers to the protection of the marine environmental protection,including protection of marine resources and protection of the marine ecosystem.

Marine organisms,including sea water is an environmental and water-capacity solution and suspended solids,sediments and marine life,the complexity of the system.Rich in marine biological resources,mineral resources,chemical and power resources,such as human resources indispensable treasure trove of resources,human survival and development of the relationship is extremely close.

At present,the protection of the marine main objective is to protect the living marine resources,so that it will not be failure for the sustainable use of mankind.Special priority should be to protect those valuable and endangered marine life in danger.According to the survey departments of the United Nations,as a result of over-fishing,accidental killing of non-target to allow the killing marine life and coastal tidal flats of the project,the mangrove deforestation,pollution of the marine environment in general,at least 25 of the worlds most valuable fisheries resources Exhausted,whales,sea turtles,manatees and other marine animals face extinction risk.With the expected expansion of the scale of ocean development,the possibility of living marine resources caused more damage.

美丽而又富饶的海底世界生活着一群自由自在的海洋生物,为了加深对海洋生物的了解,我与同学结伴去博物馆参观了海洋生物展。

在一楼,我们看到了枪鱼。海龟等海洋生物标本。其中旗鱼留给我的印象最深。旗鱼背上的鱼鳍就像一把大扇子,还有许多凸出的线条。旗鱼的眼睛就像一棵散发着光芒的黑珍珠,圆而亮。最特别的属旗鱼的嘴,又细又长,而且还很尖。还像一个大夹子,能把食物牢牢夹住,以防鱼儿挣脱。其二就是它的尾巴。像一个人字形。与它的嘴巴相同的是尾巴也很长。看到这标本,我似乎也看到了这条旗鱼当年的辉煌。它蓝色的身子与蓝色的海混在一起,稍稍一动,整个身子的优美姿态,吸引了我,也吸引了同伴们。

接下来,我们又去了四楼展厅。四楼展厅大多以贝类化石为主。美丽的贝类化石不得不使我们看得眼花缭乱。有黄色的贻贝。五颜六色的扇贝。。。。。。贝壳是贝类的生物的家,不过,随着它的生长,贝类会经常”搬家”的。贝类生物大多附生在海底的岩石上，也有生活在泥沙中的。贝的种类不同,贝壳的形状也就不一样。分双壳贝和单壳贝。牡蛎就属于双壳贝。它又叫蚝、蛎黄、海蛎子。但是牡蛎的这两个贝壳同贻贝的两个贝壳有很大的不同。贻贝的两个贝壳左右对称，而牡蛎因为是用左壳固着在岩石或其他物体上的，所以两个贝壳的大孝形状都不同。我国沿海所产的牡蛎种类，约有20种左右。最常见的有密鳞牡蛎、近江牡蛎、褶牡蛎、长牡蛎和大连湾牡蛎等5种。它又叫蚝、蛎黄、海蛎子。望着这些种类繁多的贝类,我与同伴们不禁浮想联翩……

海洋生物是人类赖以生存的宝贵财富,如今,大部分的珍惜海洋生物以濒临灭绝,而我们只能在博物馆里看到那些海洋生物的标本。化石。如果,我们再不保护海洋生物,保护海洋生物的家园,恐怕将来我们有可能会在博物馆看到现在在海洋中数量居多的鱼的化石了吧!我呼吁:从现在开始,保护海洋,珍惜海洋生物!

海洋生物与人类的关系是密切的,现在你保护海洋生物,也就是保护人类,让人类的生活环境变得更加美好!

我最喜欢的海洋生物是鲸，鲸不是鱼。鲸可以分成两类：齿鲸和须鲸。我喜欢的鲸类当然是须鲸喽!我最喜欢的海洋动物须鲸不长牙齿，它们有上百条从上颚垂下的鲸须(也叫鲸须板)。鲸须就像是过滤器，水，浮游生物和磷虾等小动物一起进入鲸的嘴里。然后，鲸用鲸须把水滤出去，浮游生物就会被留在嘴里。

蓝鲸是地球上首屈一指的巨兽，论个头堪称兽中之“王”。蓝鲸还是绝无仅有的大力士。一头大型蓝鲸所具有的功率可达1700马力，可以与一辆火车头的力量相匹敌。它能拖拽800马力的机船，甚至在机船倒开的情况下，仍能以每小时4海里～7海里的速度跑上几个小时。蓝鲸的游泳速度也很快，每小时可达15海里。蓝鲸有一个扁平而宽大的水平尾鳍，这是它前进的原动力，也是上下起伏的升降舵。由前肢演变而来的两个鳍肢，保持着身体的平衡，并协助转换方向，这使它的运动既敏捷又平稳。
