鲨鱼怎么用英语介绍
① 有关鲨鱼的介绍 （用英语）
Sharks (superorder Selachimorpha) are fish with a full cartilaginous skeleton[1] and a streamlined body. They respire with the use of five to seven gill slits. Sharks have a covering of dermal denticles to protect their skin from damage and parasites and to improve fluid dynamics.[1] They have replaceable teeth. They are some of the world's most misunderstood predators, as they very rarely attack humans unless intimidated.
Sharks include species from the hand-sized pygmy shark, Euprotomicrus bispinatus, a deep sea species of only 22 centimetres (9 inches) in length, to the whale shark, Rhincodon typus, the largest fish, which grows to a length of approximately 12 metres (41 feet) and which, like the great whales, feeds only on plankton through filter feeding. The bull shark, Carcharhinus leucas, is the best known of several species to swim in both salt and fresh water (it is found in Lake Nicaragua, in Central America) and in deltas.[2]

How long have sharks existed?
Fossil records indicate that ancestors of modern sharks swam the seas over 400 million years ago, making them older than dinosaurs! They are considered to be the first vertebrate with a complete jaw. Throughout time sharks have changed very little.
What is an "elasmobranch"? Elasmobranchs are a closely related group of fishes, differing from bony fishes by having cartilaginous skeletons and five or more gill slits on each side of the head. In contrast, bony fishes have bony skeletons and a single gill cover. Elasmobranchs include sharks, rays, and skates.
Do sharks have bones?
No, sharks and all other fishes belonging to the class Chondrichthyes lack true bone, but rather have cartilaginous skeletons.
How long do sharks live?
While longevity data are not available for many sharks, maximum ages do vary by species. Some sharks like the smooth dogfish (Mustelus canis) may only live 16 years, while others such as the porbeagle shark, (Lamna nasus) may live as long as 46 years. Whale sharks (Rhincodon typus) the largest fish in the world may live over 100 years.
What does a shark's skin feel like?
Shark skin feels exactly like sandpaper because it is made up of tiny teeth-like structures called placoid scales, also known as dermal denticles. These scales point towards the tail and helps to rece friction from surrounding water when the shark swims. Because of this, if someone rubbed the skin from the head towards the tail, it would feel very smooth. In the opposite direction it feels very rough like sandpaper. As the shark grows, the placoid scales do not increase in size, but rather the shark grows more scales. The silky shark (Carcharhinus falciformis) has small scales giving it a "silky" feel to the touch.
Do sharks sleep?
It was once believed that all sharks had to swim constantly in order to breathe and could not sleep for more than a few minutes at a time. Oxygen-rich water flows through the gills ring movement allowing the shark to breathe. While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.

shark-skin like swimsuit
A new high-performance swimsuit, developed by mimicking the skin of sharks, will be worn by top athletes in Athens from this week.
The revolutionary new fabric, developed by Speedo, is the result of four years of research and development that began with the study of shark skin at the Natural History Museum .
The new swimsuit, called Fastskin FSII, increases a swimmer's speed by recing passive drag through water by up to 4% more than the next best swimsuit.
Research into shark skin texture and movement through water was carried out under the guidance of Natural History Museum fish expert Ollie Crimmen.
Tiny 'teeth' cover the surface of a shark's skin and the shape and positioning of these 'teeth' vary across the body to manage the flow of water.
With these findings Speedo created a full 'bodyskin' with different fabrics on different parts of the body and for the first time, male- and female-specific and stroke-specific swimsuits.
Some mob movies are intentionally funny. Others carry all the blunt force of a baseball bat. "Shark Tale," a computer-animated mob spoof ---- not incidentally featuring the voices of two men previously involved in a mob movie co-starring a baseball bat ---- goes for funny.
The end result of a film made by some of the same people who brought us "Shrek" is a visually creative underwater escapade, often charming and amusing, but not supremely clever or all that heart-tugging. "Shark Tale" swims as a technically impressive entertainment, hip and supercool, but not totally engaging.
The story is of Oscar, voiced by Will Smith, who is at the bottom of the food chain, working at the local whale wash. Oscar talks the talk but doesn't walk the walk, seeking fame and glamour but never choosing wisely in his attempts to find those things. If it wasn't for the well-meaning advice of co-worker Angie (Renee Zellweger), an angelfish who harbors a secret affection for Oscar, he would be even deeper into his go-nowhere approach.
Things change thanks to happenstance. The mob-boss shark, Don Lino (Robert De Niro), runs things but has trouble getting his vegetarian son, Lenny (Jack Black), to display the toughness necessary to become a boss himself. When Oscar quite accidentally slays Don Lino's other son, Frankie, then takes undeserving credit for the kill, he becomes a hero and cultural superstar, acquiring the wealth and fame he always desired.
Trouble comes when Oscar must then repeatedly prove he's the shark-slayer he claims. Along with the way, and with the help or interference of several other comical characters ---- voiced by Martin Scorsese, Angelina Jolie, Peter Falk, Katie Couric and other talents, Oscar learns the true meaning of self-respect.
"Shark Tale" is loaded with amiable gags and likable characters, and some juicy touches that end up very funny, such as when a squirming, squealing shrimp is pleading for his life to great comical effect. It also has a primary lesson of accepting yourself and who you are as its main teaching, along with sidebar issues about respect and playing fair.
It all adds up to a reasonably amusing but not oh-wow experience, lacking the same look-at-that ingenuity as "Shrek," even if some of the small touches are very clever.
The movie gives us a chance to hear old pals De Niro and Scorsese trading funny lines ---- many of them improvised ---- taking us back to their many collaborations, including "GoodFellas," referenced above.
Smith is ready-made for the role, and other supporting voices fit just fine. Ultimately, "Shark Tale" is just that ---- fine ---- though nowhere close to a genre breakthrough. Instead, it's a mildly entertaining underwater escapade, a little too aware of itself and its hip intentions, but sometimes dazzling to observe. 有点多啊。。

鲨来鱼，被一些人认为是海自洋中最凶猛的鱼类之一。但鲨鱼中体型最大的鲸鲨却以小型海洋生物为食物，和须鲸差不多。由于食物具有某种相似性，经过漫长的生物演化，它们长得和须鲸很有相似点，这个叫做“趋同进化”。于是“鲸鲨”的名字就理所当然了。
The shark, considered by some to be one of the most ferocious fishes in the sea. But the shark in the largest whale sharks with small sea creatures for food, and whales almost. Because the food has some similarities, over a long period of biological evolution, they grow and whales very similar. This is called "convergent evolution." So the "shark" the name of behoove.
⑦ 鲨鱼皮泳衣英文介绍
鲨鱼皮泳衣是人们根据其外形特征起的绰号，其实它有着更加响亮的名字：快皮， 它的核心技术在于模仿鲨鱼的皮肤。生物学家发现，鲨鱼皮肤表面粗糙的V形皱褶可以大大减少水流的摩擦力，使身体周围的水流更高效地流过，鲨鱼得以快速游 动。快皮的超伸展纤维表面便是完全仿造鲨鱼皮肤表面制成的。此外，这款泳衣还充分融合了仿生学原理：在接缝处模仿人类的肌腱，为运动员向后划水时提供动 力；在布料上模仿人类的皮肤，富有弹性。实验表明，快皮的纤维可以减少3% 水的阻力，这在1%秒就能决定胜负的游泳比赛中有着非凡意义。1999年10月，国际泳联正式允许运动员穿快皮参赛。
而关于穿什么样的泳衣游得更快，人们已探索了许多年。泳者在水中遇到的阻力，与水的密度、泳者的正面面积、摩擦系数及泳者速度的平方成正比，因此减少正面面积和摩擦系数是设计低阻力泳衣的关键。

(8)鲨鱼怎么用英语介绍扩展阅读
鲨鱼的起源不详，但其地质学纪录可追溯到泥盆纪(4.08亿～3.6亿年前）。鲨鱼化石在中泥盆世出现，在石炭纪（3.6亿～2.86亿年前）成为占优势的脊椎动物。现代鲨鱼出现于侏罗纪早期（2.08亿～1.87亿年前），到白垩纪（1.44亿～6,640万年前）已经发展成现存的各科。
总之，除觅食和游泳机制的改进外，进化对鲨鱼的形态改变甚微。无论对化石种和现存种类来说，牙齿在鲨鱼种类鉴别方面均有很重要作用。

蝶鱼(BUTTERFLY FISH) -------------------------------------------------------------------------------- ~ Sea Snakes ~ NAME: Sea snake is the common name for certain marine members of a family of venomous snakes. HABITAT: Sea snakes inhabit tropical waters from the Indian ocean to the Pacific ocean. Sea snakes are particularly abundant in the Persian Gulf and the Bay of Bengal. SIZE: Most sea snakes are not large, ranging from about 1.6 to 3.3 feet in length, although Stokes's sea snake can reach nearly 6 and a half feet. REPRODUCTION: One group of sea snakes, sometimes called the true sea snakes, give birth to live young and lack the enlarged ventral scales typical of most terrestrial snakes. The other group, sometimes referred to as seakraits, lay eggs; because they must leave the water to deposit their eggs, they retain straplike ventral scales, although these may be smaller than those of terrestrial snakes. SWIMMING: The paddlelike tail of sea snakes is wide and compressed and makes an effective swimming organ. BREATHING: Unlike eels, sea snakes have no gills and must rise to the surface of the water for air, but they can remain underwater for several hours, obtaining dissolved oxygen from water that they swallow and eject. FEEDING: Many species feed on elongate fishes, such as eels, which they paralyze with their venom. BEHAVIOR: Sea snakes are generally not aggressive and usually will not bite humans unless handled roughly or forcibly restrained. VENOM: Sea snakes are highly venomous, and bites, though rare, are fatal. COMMON SPECIES: The yellow-bellied sea snake, one of the most common sea snakes, ranges along the Pacific coast from southern California to northern South America. It is less than 3 and a quarter feet long and is black or dark brown with a bright yellow belly. SCIENTIFIC CLASSIFICATION: Sea snakes are usually classified in two subfamilies, the Hydrophiinae and the Laticaudinae, both in the family Elapidae. Some taxonomists classify them instead in two families, the Hydrophiidae and Laticaudidae, separate from the family Elapidae. Stokes's sea snake is classified as Astrotia stokesii. The yellow-bellied sea snake is classified as Pelamus platurus. 海蛇长了一口毒牙。其喷射的毒液，比陆地上最毒的眼镜蛇的毒液的毒性还要大50倍。海蛇的毒液属于神经毒素。人被海蛇咬伤后，从毒液进入人体到出现症状，一般要经过4个小时才发病。在此之前，没有什么明显症状，只有一点麻木和刺痛的感觉。4个小时后，毒素一旦发作，患者就会出现全身肌肉酸痛、眼睑下垂、颈部强直、心脏和肾脏受损。如果抢救无效，患者最终将死于心脏衰竭。海蛇可以制药。蛇毒可以用来制成各种单价或多价抗毒血清。用这种抗毒血清，可以治疗毒蛇咬伤。海蛇毒可以提取多种活性酶。这些活性酶可以在医药和科研中使用。使用海蛇毒素研制成的新型镇痛药，对三叉神经痛、坐骨神经痛等顽固性神经疼痛具有良好的镇痛效果。此外，对恶性肿瘤引起的剧痛，也有明显的镇痛效果。用海蛇毒制作的镇痛药，和镇痛药物吗啡相比，虽然起效稍慢，但是镇痛时间长，不会成瘾，所以很受欢迎。我国用海蛇治疗风湿性关节炎、腰背痛、肌肉麻木等疾病的传统方法是，活蛇入酒，浸死，然后取出来，洗干净，封存在60度的酒中半年以上，每次服用少量，同时用酒擦身。海蛇肉和蛋都有良好的补益作用。将海蛇肉或者海蛇蛋炖食，可以治疗营养不良，并且有强身壮体的功效。海蛇胆可以驱风活血，蛇油还可以养护肌肤，是良好的护肤佳品。
⑩ 怎样用英文描述鲨鱼
Sharks are the most fierce animal in the ocean. they appear in the earth about 300,000,000 years before dinosaurs. The skin of sharks are always inrate and slippery, and it's very sensitive to the other objects in the ocean. Marine animals such as fishes, shrimps and crabs are elementary food for sharks. Even though, some kind of sharks still attack human beings, e.g. great white sharks. During these recent years, the total number of sharks has Significantly reced, owning to their expensive fins.
