写海洋动物的英语作文篇一:
Marine environment is one in water seawater tolerance hydrolyzate and suspended solids seabed sediment and marine organisms including complex systems. Ocean rich biological resources mineral resources chemical resources and power resources is an indispensable resource treasure house of human beings with human survival and development of the relationship very close.
The main objective of the current marine conservation is to protect the living marine resources so as not to failure in order for human sustainable use. In particular give priority to protect those valuable and critically endangered marine life. According to the UN for investigation due to overfishing accidental capture and killing of non-target to allow hunting of marine coastal shoreline construction mangrove deforestation widespread marine pollution at least the world's 25 most valuable fishery resources depleted whales sea turtles manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development
Marine living resources are likely to cause more damage.The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat in particular their migration spawning foraging avoiding predators coast tidal flats estuaries coral reefs it is necessary to prevent the heavy metals pesticides oil organic and easy to produce nutrients such as eutrophication of marine pollution.

写海洋动物的英语作文篇二:
In the animal kingdom, both predators and prey species utilize one of two things to survive—stealth or speed. Both on land and beneath the sea, those who master either evasion or capture through these methods will thrive, living to reproduce and achieve the unspoken directive of their species. While stealth—through camouflage or evasion—is common, perhaps the most thrilling feature of many of the animals we find in the ocean are the fantastic speeds that can not only be achieved, but often maintained for long periods of time.Speed represents a tremendous expenditure, an investment of energy that must be replenished via consumed calories. Therefore, any observer should marvel not only at the existence of this trait, but also at the bounty of an ecosystem and the ability of individuals to draw their needs from that system. Their existence is a reflection of the fantastic diversity and abundance of our oceans. Here are ten of the fastest aquatic animals—both predator and prey.
动物世界里,不管是捕食者还是被捕食者,暗袭和速度是它们赖以生存的两大法宝。许多陆地和海洋生物正是通过这两项技能得以繁衍成长,维持在自然界中的生存地位。对于暗袭,大多数动物拥有独特的保护色和逃遁技巧,以此捕食或躲避天敌。然而,在海洋世界,失去遮蔽物和光线,速度才是生存王道。许多海洋生物爆发力惊人,不仅可以很快达到超高时速,更为赞叹的是凭借其惊人耐力能游行数小时。长时间竞速意味着巨大的体能消耗,需要通过摄入大量卡路里补充体力。因此,人们不仅会对这一特点感到惊奇,更会对它们身处生物系统底部却能以个体能力获得所需而惊叹不已。它们的存在就是海洋多样性及丰富性的最好体现。
写海洋动物的英语作文篇三:
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.
写海洋动物的英语作文篇四:
This fish earned its name by utilizing evasion as a way to escape its predators. It bodily leaps from the ocean, reaching a speed of about 35 miles per hour and a recorded gliding time of up to thirty seconds. This can take them as far as 200 meters from their point of exit from the water, which may be far enough to escape pursuit or confuse predators. Fishermen favor these types of fish, but due to their sheer numbers in the wild, none of the 40 different species of flying fish are listed as endangered. While they can be found foraging seasonally along the outskirts of warm water reef complexes, flying fish are primarily pelagic, and favor tropical or subtropical open waters around the equator.
飞鱼得名于它独特的避难方式。遇到捕食者时,飞鱼会采用一种独特的逃跑方式:它会纵身一跃,跳出海面。此时它的速度可达到每小时35英里,在空中滑翔长达30秒。这一跃能使它们飞行200米,足以使它们全身而退或者迷惑捕食者。渔民们很是钟爱这种鱼,野生飞鱼数量众多,所以40种飞鱼中没有一种濒临灭绝。人们发现飞鱼有时会季节性的在温水区近郊地带的杂礁灰岩附近觅食,不过它们属浮游类鱼类,喜欢在赤道附近的热带,亚热带地区的公海活动。
Subsisting mainly on a diet of plankton and small marine life, flying fish are schooling fish that hunt primarily at night. While some sources may find this counter-intuitive, given the ease with which the fish are drawn to light sources, this actually makes perfect sense. Many of the plankton and marine resources the fish favor are slightly luminescent, especially by moonlight, making them easily seen in the darkness. This also provides cover, given the coloration of the fish—blue or grey on top, silvery white on the bottom—so that they are not easily seen from above or below as they feed on the clouds of marine flora. Flying fish generally mate during the autumn or spring, when currents are at their weakest. Females will deposit their eggs on the surface, attached to flotsam, and males will fertilize the eggs. Schools at this time can number in the millions, and constitute a major resource for species that feed on the fish. Because they only tend to live about five years in the wild, their flesh is prized for its purity—free of the heavy metals often found in longer-lived species.
飞鱼主要以浮游生物和小型海洋生物为食,主要在夜间以集群的方式进行捕食。有些人会觉得下面这个说法有悖常理,因为鱼类易被光源吸引,这么说也不无道理。许多浮游生物和鱼类自身都会发出微弱的冷光,尤其是在月光照射下,更是清晰可见。但这同时也为鱼类提供了一层防护,让它们有了保护色:一般在上部会呈现蓝色或灰色,下部呈现银白色。凭借这些保护色,当飞鱼在海底植物中进食时就很难发现它们。飞鱼通常会在春秋时节进行交配,因为这个时期洋流的活动最为和缓。雌性飞鱼会将卵产在海面上,让其依附在漂浮物上,雄性飞鱼再让鱼卵受精。此时在飞鱼的集群中,会有数以百万的成员。而这也为以鱼类为生的动物们提供了主要的.食物来源。由于野生飞鱼只有5年的寿命,它们不会像长寿的鱼类一样体内留有大量重金属物质,因此飞鱼肉被人们视为珍品。
写海洋动物的英语作文篇五:
Orcas are not related to whales at all, other than being ocean-dwelling mammals. Rather, they are close kin to dolphins. While it was believed that they were a single species, recent research indicates that they may, in fact, be comprised of several different species of Orca. You can find them in every ocean in the world, though they tend to favor the colder waters around Antarctica and the North Atlantic or Pacific. The only predator they possess is humankind. While there's a deadly standoff between the two species, Orcas proliferate in the wild, and have an incredible life span. The males usually live as long as sixty or seventy years, while the females—who are excluded from the sometimes-violent competition for mates—may live a hundred years or more in the wild.
虽名虎鲸,但不同于海洋其他哺乳动物,非鲸目,海豚科的近亲。此前一直认为虎鲸只有一种,但最近的调查显示虎鲸种类繁多。部分虎鲸会终年停留于南极、大西洋北部和太平洋等温度较低的海域,但总体来看,它们的活动范围几乎覆盖全世界水域。它们堪称海上霸王,唯一的天敌也只有人类了。虎鲸全年都可以交配,数量庞大,雄鲸的平均寿命在60到70年左右,野生雌鲸不同于雄鲸经常参与猎杀食物,寿命可达100年甚至更长。
They've been observed reaching speeds of around 30 miles per hour, although some Orcas may utilize much greater bursts of speed, based upon their favored prey. Resident pods in the Pacific Northwest have shown a decided preference for salmonids—specifically, Chinook salmon. This presents a conflict with the goals of companies that rely on high yields of salmon for profit. Several communities of killer whale seem to favor beach and ice floe ambush approaches, snatching seals and walruses or even sea birds from their resting places. Others, located in the Southern Hemisphere, take up the challenge of hunting sharks in the open sea, as well as feeding on species of rays and other fish abundant in the cold southern waters.
虎鲸约时速30英里,当然也有爆发力更强的,为了追捕中意的猎物,时速可以更快。太平洋西北海域的虎鲸族群偏爱三文鱼,尤其是大鳞三文鱼。这就和沿岸经营三文鱼生意的公司产生一定的利益冲突。虎鲸族群喜欢在浮冰区伏击猎物,捕杀海豹、海象或者在这里歇脚的海鸟。在南半球海域里,有些虎鲸还会在公海里捕杀鲨鱼,也会以鳐和其他鱼类为食。
