Delightful Dolphins of the Deep 深海精灵──海豚

by Rachel Black

For ages, sailors have said that it is good luck to see dolphins swimming alongside boats. Their presence meant that land was near, which would be vital information if a boat and her crew were in danger. Some dolphins have even protected shipwrecked sailors from sharks. It is no wonder that these unique and fascinating creatures have long been known as our friends.
长久以来,水手们都说看见海豚跟在船边游是件很幸运的事。牠们的出现代表陆地就在附近,这对一艘遭遇危险的船只及其船员来说是极重要的信息。有些海豚还会保护遇难水手不受鲨鱼攻击。难怪这独特又迷人的生物一直被视为人类的好朋友

You may think dolphins are fish, but they are actually mammals. They are related to whales and porpoises, and they evolved around 10 million years ago. Dolphins breathe air, give birth to live young, and feed them milk. They are social animals, living together in groups called pods or schools that range in size of up to 12. In places rich in food, many schools can combine together to form pods of up to 1,000 dolphins.
你也许会认为海豚是鱼类,但事实上牠们是哺乳类动物。牠们与鲸鱼和鼠海豚属于同一类,约在一千万年前便已进化完成。海豚呼吸空气、生育下一代并哺乳。牠们是群居动物,一群可达 12 只不等的海豚生活在一起,称为 pod 或 school。在食物丰富的地方,许多群海豚聚集在一起时,可形成数量多达一千只的海豚群。

Dolphins are thought to be intelligent animals because of their playfulness, curiosity, and quick ability to learn. They seem to communicate with each other through a combination of squeaks, whistles, and clicks. While scientists don't know what they are going on about, it is thought that dolphins are telling each other that food is nearby, or warning each other of approaching danger. Dolphins use sonar to discover an object's size, shape, and location. By sending out a series of clicks and receiving the echo that bounces off the object, they can differentiate between a shark and a boat.
由于海豚爱玩、好奇心重,而且学习速度很快,因此被认为是很聪明的动物。牠们似乎会以结合了吱吱声、口哨或卡嗒的声响相互沟通。虽然科学家不确定牠们在做些什么,但此举被认为是海豚在告诉彼此食物就在附近,或警告危险将至。海豚利用声纳探测物体的大小、形状和所在位置。藉由发送一连串卡嗒声并从物体反弹的回音,牠们便能区分鲨鱼和船只。

Unfortunately, dolphins have faced increasing danger in recent years. Fishermen in pursuit of profitable tuna may accidentally trap dolphins in their nets, killing them in the process. These intelligent mammals of the sea deserve our protection and respect.
不幸的是,海豚近年来面临日益扩大的危机。想靠鲔鱼大赚一笔的渔夫可能会意外使海豚困在渔网中,而让牠们在受困过程中致死。这些聪明的海中哺乳类应该要受到保护和尊敬才是。
