如题所述

Answer 1

Whale is the common name for various marine mammals of the order Cetacea. The term whale sometimes refers to all cetaceans, but more often it excludes dolphins and porpoises, which belong to suborder Odontoceti (toothed whales). This suborder also includes the sperm whale, killer whale, pilot whale, and beluga whale. The other Cetacean suborder Mysticeti (baleen whales), are filter feeders that eat small organisms caught by straining seawater through a comblike structure found in the mouth called baleen. This suborder includes the blue whale, the humpback whale, the bowhead whale and the minke whale. All Cetacea have forelimbs modified as fins, a tail with horizontal flukes, and nasal openings (blowholes) on top of the head.
Whales range in size from the blue whale, the largest animal known to have ever existed at 35 m (115 ft) and 136 tonnes (134 LT; 150 ST), to various pygmy species, such as the pygmy sperm whale at 3.5 m (11 ft).
Whales collectively inhabit all the world's oceans and number in the millions, with annual population growth rate estimates for various species ranging from 3-13%. For centuries, whales have been hunted for meat and as a source of raw materials. By the middle of the 20th century, however, industrial whaling had left many species seriously endangered, leading to the end of whaling in all but a few countries.

鲸是海洋哺乳动物中鲸目生物的俗名，鲸目之下包括有海豚科。但在日常语言中，人们将鲸和海豚分开。海豚科属於鲸目下的齿鲸亚目，该亚目中有抹香鲸及白鲸等。而以鲸须替代牙齿，利用过滤水中浮游生物进食的须鲸亚目，有座头鲸及地球上最大的哺乳动物蓝鲸等。
数世纪以来，鲸经常被作为桌上佳肴或是工业产品的原料。然而，到了20世纪中叶，鲸的数量已经因为捕鲸工业的盛行而锐减，成为了濒临绝种的生物。所幸现阶段大多数国家都已经在八零年代签下全球禁捕令，停止捕鲸工业的持续发展。
