Warming-up
whale
n.鲸
鲸的体型是世界上存在的动物中最大的，它是终生生活在水中的哺乳动物，对水的依赖程度很大。鲸形状像鱼，鼻孔在头的上部，用肺呼吸。它体长可达三十米，是现在世界上最大的动物。鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟，长须鲸可在水下300-500米处待上1小时，最大的齿鲸——抹香鲸能潜至千米以下，并在水中持续2小时之久。

曾广泛分布于中国东部、日本、俄罗斯、朝鲜等地，由于环境恶化,大量的水田农药，生存空间越来越狭小导致种群数量急剧下降，至20世纪80年代仅我国陕西省南部的汉中市洋县秦岭南麓仅有7只野生种群，后经人工繁殖，种群数量已达到2000多只
由于人类的过度开发，乱砍森林，金丝猴的栖息地越来越小，他们的生存空间受到威胁，因而他们的繁衍也受到了濒临灭绝的威胁。
