A couple of days ago, my dad and I go to the supermarket to buy things. Kingwe saw the sea shark, a shark that is cut in two, I think: sharks in the ocean so ferocious, and King of the sea anyway! But for now, or are we human beings killed, for sale, sell us to eat.

In my opinion, there seem to be two kinds of sharks (character), but the fact that sharks have only one character, in my imagination, the first is: fierce sharks, second: no use of sharks.

In these two species of shark, ferocious sharks is under what circumstances could use the title of it? Is swimming around in the ocean, and very handsome King in front of the sea. Useless shark is a shark be captured by humans, killing, for sale with title.

In the evening, father settle when I went to bed, my dad said to me: "today we see that the shark was cut in two in the future will be eaten by humans, do we humans are cruel, don't you think? "

I replied:" it's very cruel, but, if not cruel, we would starve. Because we still have to eat meat or something. Also, what other herbivores, for example eating cattle, sheep, and our homes not turned into a desert.

Grass, we have better homes. But we are a little cruel. "Dad just smiled and walked out of my room.

The White Shark: Introduction (介绍)

Many paleontologists are very interested in living groups, because the study of the living organisms can both unlock their evolutionary history and provide important keys towards interpreting their fossil record. Some living groups have ancient histories. For example, sharks have existed as a group for over 350 million years! Today, sharks and rays (elasmobranchs) are represented by over 600 species that show a remarkable range of ecological and morphological diversity. Unlike the true fishes, sharks do not have internal bone, but instead have a cartilaginous skeleton. Although many people are told that sharks are primitive in comparison to other groups, this is not true. Many sharks are efficient and specialized hunters that have thrived for millions of years.

This small exhibit shows an amazing predator: the great white shark (Carcharodon carcharias). The white shark is found in temperate waters throughout the world's oceans, and it is an important, though not common, predator in California's coastal habitats. Scientists from several organizations throughout California including the Point Reyes Bird Observatory, the Marine Mammal Center, the California Academy of Sciences, Bodega Bay Marine Laboratory, California Department of Fish and Game, and the Museum of Vertebrate Zoology at UC Berkeley, have been studying white sharks and their prey for several years in hopes to better understand their behavior and ecology.

Food and Feeding（觅食?) Behavior (行为)

White sharks are predatory animals that begin life by feeding on fish, rays, and other sharks, and as they grow, switch to feeding on marine mammals and scavenging on large animal carcasses. Their first mammalian prey are usually the small harbor seal, but as the sharks increase in size, they become large enough to eat sea lions, elephant seals, and small toothed whales. Attack strategy consists of a swift, surprise attack from below, inflicting a large, potentially fatal bite. The pinniped often dies from massive trauma or blood loss, but the bites may be superficial or misplaced on the body, allowing the seal to escape and survive the attacks with their scars as witness. Large white sharks will also scavenge on the carcasses of whale sharks, and on the fat-rich blubber layer of dead whales. They will occasionally feed on sea turtles and sea otters, and are known to attack, but not eat, humans.

Habitat(栖息地) and Distribution{;(生物的)分布区域}

The waters off central California offer a rich bounty of food for white sharks, and every summer and fall they actively feed in nearshore areas. The Farallon Islands, a national wildlife refuge about 27 miles off San Francisco, is a common feeding ground for the sharks. Four species of pinnipeds, the northern elephant seal, the California sea lion, the Steller sea lion, and the harbor seal, live around and breed on these islands, making a plentiful food resource for the white sharks. The coastal waters along central California, especially around the Año Nuevo State Reserve and along the Marin Headlands, is another common feeding area for the sharks. In the summer the sharks feed on seals and sea lions along the coast as far north as Oregon and occasionally the Gulf of Alaska, and in the Fall, they turn south and feed along the offshore islands. It is believed that female white sharks migrate to southern California to give live birth to their offspring. In abnormally warm-water (El Niño) years, white sharks are more plentiful off central California because both they, and their prey, are shifted north. The years 1984-84 and 1991-92 show high trends in white shark predatory activity, and were the warmest oceanic seasons in recent history.

求关于大白鲨的英文资料!!!

成千上万的备用牙

我们人类更换牙齿只是在小时候才进行，当长大后就不再可能更换牙齿。而且即使在小时更换时,也是先前的脱落,然后在牙床上再慢慢长出新牙。可是，海里的大白鲨在这一点上却与人类大不相同。它那血盆大口中，上鄂排列着26枚尖牙利齿，一旦大白鲨前面的任何一枚牙齿脱落，后面的备用牙就会移到前面补充进来。在任何时候，大白鲨的牙齿都有大约三分之一处于更换过程之中。据估计，大白鲨一生之中将丢失并更换成千上万枚牙齿。如果大白鲨的牙齿也可以卖钱的话，那么大白鲨也将是千万富翁。

想想看，我们人类要是也有这样的本领该多好啊，不过如果那样的话，可能牙医和口腔医院就要失业或者关门了。

头部直立于水面

你见过鱼类可以把头竖立在水面上么？在所有的鲨鱼之中，大白鲨是惟一的可以把头部直立于水面之上的鲨鱼，这赋予它们在水面之上寻找潜在猎物的优势。不过，大白鲨通常是在水下发起攻击的。

电影明星

大白鲨还是超级明星。在《星球大战》电影出现之前，好莱坞的《大白鲨》是最卖座的电影，当年这部成本仅有800万美元的电影票房收入却达26亿美元，收入与成本比值达到325倍，创造了一个奇迹！

游泳冠军

大白鲨在水中的泳速最高可达43英里每小时，合计69千米每小时，在中国许多汽车没上高速公路之前，大部分汽车都达不到这个速度。它的这个速度相当于奥运百米冠军速度的85倍。科学家曾经在加州海边跟随一条鲨鱼直到夏威夷，行程2400英里（3862千米）--仅仅用了40天！

杂食家

虽然他们最喜捕食海豹、海狮，偶尔也会吃海豚，但除此之外他们也吞食许多其他东西，如海獭、海面上漂浮的死鱼等。在解剖许多大白鲨的胃部时，人们发现里面有瓶子、罐头壳、草帽、捕龙虾的笼子甚至还有布谷鸟。这充分说明，大白鲨并不是挑食的动物，它是一个不折不扣的杂食家。

他们有耳朵么？

大白鲨有耳朵么？虽然从外面看不见，但大白鲨确实是有耳朵的。大白鲨通过位于颅骨内两个很小的传感器来辨听声音。有时他们能专注倾听接受来自受伤的鱼或者是海豹发出的呻吟声。

高于周围水温的体温

人类的体温维持在37摄氏度左右，但是生活在水中的鱼类的体温可没有这么高，它们体温通常和周围水温一样。但是大白鲨却很特殊，他们的体温要比周围水温要高得多，最多时高出15摄氏度。这一点对于大白鲨很有用，高体温可以帮助他们游得非常快，而且有助于消化良好。

体态宽胖的怀孕妈妈

一头怀孕的雌性大白鲨其腹部最多可以容纳14个小白鲨。而且小白鲨出生时长达152米，22公斤重，�就象一个十几岁的孩子一样。想象一下，如果一头大白鲨腹部装了14条小白鲨，那么其重量将达308公斤，换句话说，相当于14个十几岁的人类孩子。成年大白鲨平均体长在3米到49米之间，雌性比雄性要大一些。目前已知最大的大白鲨长度达7米，体重3200公斤。但是无论是雄是雌，他们都是最大的食肉者。

全是白色的么？

虽然名字是叫大白鲨，但他们并不全都是白色的。其腹部是灰白色，背部则是暗灰色。这可以帮助他们有效地隐藏自己。从上面看去，他们的背部暗色很容易与深色海面融为一体，而从下方往上看，他们的灰白色的腹部又与带着亮光的水面相匹配。

他们吃人么？

“他们吃人么？”看起来不是这样的。有些科学家认为将大白鲨描述为“咬人鱼”似乎更确切。在大白鲨攻击游泳者事件中，大部分都只是在他们离开前咬一下人类而已。科学家们认为这也许是人类的肉吃起来没有海豹、海狮那么香！

天哪，但愿大白鲨永远也不要觉得人类的肉好吃。

求英文鲨鱼简介........

Sharks are a type of fish.

There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. The biggest whale shark can grow to twenty meters in length. Sharks do not have bones. The skeleton of a shark is made of cartilage. Human noses and ears are also made of cartilage.

A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. Sharks also sense electrical and magnetic energy linked to nerves and muscles of living animals.

英语作文 大白鲨

The great white shark, also known as great white, white pointer, white shark, or white death, is a large lamniform shark found in coastal surface waters in all major oceans. The great white shark is very well known for its size, with the largest individuals known to have approached or exceeded 6 metres (20 ft) in length,and 2,268 kilograms (5,000 lb) in weight.It reaches maturity at around 15 years of age and can have a life span of over 30 years.

The great white shark is arguably the world's largest known extant macropredatory fish and is one of the primary predators of marine mammals. It is also known to prey upon a variety of other marine animals including fish, pinnipeds, and seabirds. It is the only known surviving species of its genus, Carcharodon, and is ranked first in a list of number of recorded attacks on humans.

The best selling novel Jaws and the subsequent blockbuster film by Steven Spielberg depicted the great white shark as a "ferocious man eater". In reality, humans are not the preferred prey of the great white shark.
