鲨鱼的英语作文 篇一：鲨鱼的生态角色

Sharks are fascinating creatures that play an important role in the ecosystem. As apex predators, they help maintain the balance of marine life and ensure the health of our oceans. In this essay, we will explore the ecological significance of sharks and why they deserve our protection.

Firstly, sharks are crucial in controlling the populations of other marine species. By preying on weaker or injured individuals, they help eliminate any potential threats to the overall health of the ecosystem. This process is known as "top-down control," where sharks keep the populations of their prey in check, preventing overpopulation and maintaining a diverse and balanced marine community.

Secondly, sharks also help regulate the behavior and distribution of marine animals. Their presence alone can influence the behavior of other species, preventing them from becoming too complacent or causing disruptions in the food chain. Moreover, sharks tend to inhabit specific areas, creating a natural habitat segregation that allows different species to coexist without excessive competition for resources.

Furthermore, sharks contribute to the health of coral reefs. As predators, they control the populations of herbivorous fish that feed on algae, preventing overgrazing and allowing coral reefs to thrive. Healthy coral reefs are essential for the survival of numerous marine species, making sharks indirectly responsible for the preservation of biodiversity in these ecosystems.

In addition to their ecological role, sharks also have significant economic value. Shark diving tourism has become increasingly popular, attracting millions of visitors each year. These tourists contribute to local economies by spending money on accommodations, food, and other activities. Protecting sharks not only ensures the sustainability of this industry but also promotes conservation efforts and raises awareness about the importance of marine ecosystems.

Despite their ecological and economic significance, sharks are facing numerous threats. Overfishing, habitat destruction, and climate change have led to a decline in shark populations worldwide. It is crucial for governments, organizations, and individuals to take action and implement measures to protect these magnificent creatures.

In conclusion, sharks are vital to the health and balance of marine ecosystems. Their role as apex predators helps control populations, regulate behavior, and contribute to the preservation of coral reefs. Additionally, sharks have economic value through shark tourism. It is essential for us to recognize the importance of sharks and work together to protect and conserve these remarkable creatures for future generations.

鲨鱼的英语作文 篇二：鲨鱼的生活习性

Sharks are fascinating creatures with a unique set of behaviors and adaptations that allow them to thrive in their marine habitats. In this essay, we will explore the fascinating life of sharks and gain a deeper understanding of their incredible abilities.

Firstly, sharks are known for their exceptional sense of smell. They can detect the scent of blood from miles away, thanks to the specialized olfactory organs located in their snouts. This keen sense of smell helps them locate prey, even in the vastness of the ocean. It is estimated that a shark can detect just one drop of blood in a million drops of water.

Secondly, sharks have an incredible ability to sense electrical fields. Specialized organs called "Ampullae of Lorenzini" located on their heads allow them to detect the weak electrical signals emitted by other animals. This sense helps them locate hidden prey, even in murky waters or at night when visibility is limited.

Furthermore, sharks have a unique reproductive strategy. Most sharks are ovoviviparous, meaning they give birth to live young after the eggs hatch internally. This allows the mother to protect and nourish her offspring until they are ready to survive independently. Some shark species, such as the great white shark, have long gestation periods and give birth to relatively few offspring, ensuring their survival in the harsh marine environment.

In terms of feeding habits, sharks display a wide range of behaviors. While some species are opportunistic feeders and will consume anything they come across, others have specialized diets. For example, the whale shark is a filter feeder, consuming plankton and small fish by filtering them through its gills. On the other hand, the tiger shark is known for its scavenging behavior, often feeding on carrion or even garbage.

Lastly, sharks have an incredible ability to adapt to their surroundings. They have been around for millions of years and have survived numerous environmental changes. Their bodies are streamlined for efficient swimming, and their skin is covered in dermal denticles, which reduce drag and increase swimming speed. These adaptations have allowed sharks to become highly efficient predators and survivors in the marine environment.

In conclusion, sharks possess a variety of fascinating adaptations and behaviors that enable them to thrive in their marine habitats. From their exceptional sense of smell and ability to detect electrical fields to their unique reproductive strategies and feeding habits, sharks are truly remarkable creatures. Understanding and appreciating their incredible abilities is essential for their conservation and the overall health of marine ecosystems.

鲨鱼的英语作文

　　导语：很多鲨鱼包括大白鲨，口中都有成排的利齿。只要前排的牙齿因进食脱落，后方的牙齿便会补上。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

　　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 reducing 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.

　　电影的'最终结果由一些相同的人们给我们带来的“怪物史莱克”是一个视觉创意水下越轨行为,通常都是迷人和有趣的,但不是非常聪明或heart-tugging。“鲨鱼黑帮”游泳技术令人印象深刻的娱乐,臀部和过冷,但不是完全接触。

　　奥斯卡的故事,由威尔·史密斯表示,他是食物链底部的,工作在当地的鲸鱼洗。奥斯卡会谈讨论但不付诸行动,寻求名声和魅力,却从未在他试图找到明智地选择这些事情。如果不是同事安琪的忠告(蕾妮·齐薇格),一位神仙鱼港口一个秘密喜欢奥斯卡,他甚至会深入无尽的方法。

　　这部电影给了我们一个机会听到老朋友德尼罗和斯科塞斯交易有趣的台词——其中许多简易——带我们回到他们的许多合作,包括“好家伙”,上面的引用。

　　史密斯是现成的角色,和其他支持的声音配合得很好。最终,“鲨鱼黑帮”就是——好——虽然离一个类型的突破。相反,它是一个温和的娱乐水下越轨行为,有点太意识到本身和它的臀部的意图,但有时令人眼花缭乱的观察。
