  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。
