鯊魚怎麼用英語介紹
① 有關鯊魚的介紹 (用英語)
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. 有點多啊。。

鯊來魚,被一些人認為是海自洋中最兇猛的魚類之一。但鯊魚中體型最大的鯨鯊卻以小型海洋生物為食物,和須鯨差不多。由於食物具有某種相似性,經過漫長的生物演化,它們長得和須鯨很有相似點,這個叫做「趨同進化」。於是「鯨鯊」的名字就理所當然了。
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 鯊魚皮泳衣英文介紹
鯊魚皮泳衣是人們根據其外形特徵起的綽號,其實它有著更加響亮的名字:快皮, 它的核心技術在於模仿鯊魚的皮膚。生物學家發現,鯊魚皮膚表面粗糙的V形皺褶可以大大減少水流的摩擦力,使身體周圍的水流更高效地流過,鯊魚得以快速游 動。快皮的超伸展纖維表面便是完全仿造鯊魚皮膚表面製成的。此外,這款泳衣還充分融合了仿生學原理:在接縫處模仿人類的肌腱,為運動員向後劃水時提供動 力;在布料上模仿人類的皮膚,富有彈性。實驗表明,快皮的纖維可以減少3% 水的阻力,這在1%秒就能決定勝負的游泳比賽中有著非凡意義。1999年10月,國際泳聯正式允許運動員穿快皮參賽。
而關於穿什麼樣的泳衣游得更快,人們已探索了許多年。泳者在水中遇到的阻力,與水的密度、泳者的正面面積、摩擦系數及泳者速度的平方成正比,因此減少正面面積和摩擦系數是設計低阻力泳衣的關鍵。
英文:::The shark dried shark skin swim suit is the people according to the nickname which its contour characteristic gets up, actually it has a more resounding name: The quick skin, its core technologies lies in the imitation shark's skin. The biologist discovered that the shark skin surface roughness V shape folds may rece fluent greatly the friction force, causes around body's current of water to wind through highly effective, the shark can hover fast. The quick skin's ultra extension textile fiber surface is copies the shark skin surface to make completely. In addition, this model of swim suit also fully fused the bionics principle: Imitates humanity's tendon in the connecting point, delimits when backward the water for the athlete provides the power; Imitates humanity's skin on the cotton material, high resilience. The experiment indicated that the quick skin's textile fiber may rece 3% water the resistance, this in 1% seconds can decide that the victory and defeat in the swim meet has the extraordinary significance. in October, 1999, Guojiyonglian allowed the athlete to put on the quick skin participation officially.what swim suit but does about put on to tour quickly, the people have explored for many years. The swimming the resistance which meets in the water, with water density, swimming frontal face area, friction coefficient and the swimming speed's square is proportional, therefore reces the frontal face area and the friction coefficient designs the low resistance swim suit's key.

鯊魚的起源不詳,但其地質學紀錄可追溯到泥盆紀(4.08億~3.6億年前)。鯊魚化石在中泥盆世出現,在石炭紀(3.6億~2.86億年前)成為占優勢的脊椎動物。現代鯊魚出現於侏羅紀早期(2.08億~1.87億年前),到白堊紀(1.44億~6,640萬年前)已經發展成現存的各科。
總之,除覓食和游泳機制的改進外,進化對鯊魚的形態改變甚微。無論對化石種和現存種類來說,牙齒在鯊魚種類鑒別方面均有很重要作用。

蝶魚(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. 海蛇長了一口毒牙。其噴射的毒液,比陸地上最毒的眼鏡蛇的毒液的毒性還要大50倍。海蛇的毒液屬於神經毒素。人被海蛇咬傷後,從毒液進入人體到出現症狀,一般要經過4個小時才發病。在此之前,沒有什麼明顯症狀,只有一點麻木和刺痛的感覺。4個小時後,毒素一旦發作,患者就會出現全身肌肉酸痛、眼瞼下垂、頸部強直、心臟和腎臟受損。如果搶救無效,患者最終將死於心臟衰竭。海蛇可以制葯。蛇毒可以用來製成各種單價或多價抗毒血清。用這種抗毒血清,可以治療毒蛇咬傷。海蛇毒可以提取多種活性酶。這些活性酶可以在醫葯和科研中使用。使用海蛇毒素研製成的新型鎮痛葯,對三叉神經痛、坐骨神經痛等頑固性神經疼痛具有良好的鎮痛效果。此外,對惡性腫瘤引起的劇痛,也有明顯的鎮痛效果。用海蛇毒製作的鎮痛葯,和鎮痛葯物嗎啡相比,雖然起效稍慢,但是鎮痛時間長,不會成癮,所以很受歡迎。我國用海蛇治療風濕性關節炎、腰背痛、肌肉麻木等疾病的傳統方法是,活蛇入酒,浸死,然後取出來,洗干凈,封存在60度的酒中半年以上,每次服用少量,同時用酒擦身。海蛇肉和蛋都有良好的補益作用。將海蛇肉或者海蛇蛋燉食,可以治療營養不良,並且有強身壯體的功效。海蛇膽可以驅風活血,蛇油還可以養護肌膚,是良好的護膚佳品。
⑩ 怎樣用英文描述鯊魚
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.
