　　蓝鲸是世界上最大的动物，全身呈蓝灰色。目前捕到的最大的蓝鲸地点在大西洋的福克兰群岛附近。这条蓝鲸长33.5米，体重195吨这远比大象大得多了它的舌头重约3吨它的心脏重700公斤，肺重1500公斤,血液总重量约为8吨～9吨,肠子有半里路长。这样大的躯体只能生活在浩瀚的海洋中。鲸是歌唱家水中杰出的“歌唱家”当推“座头鲸”。1971年，美国生物学家对从海上寻下的“座头鲸”发声进行了分析，发现了极其特殊的声音信号。原来这些“座头鲸”发出一连串优美动听、调子不一的婉转声。这些声音延续了30分钟，然后从头唱起，从抑扬顿挫、轻曼悦耳的程度判断，可鲸遨游大海时从来不会迷失方向。鲸的种种用处对人是很有好处的，现在鲸大量的死亡，使人类也走向灭亡，我们要保护鲸类，让它们继续生栖繁衍。让人们根据它们的好处，制造出更先进的仪器，鲸是人类的朋友。为什摸？不错，我这里还有一点资料：鲸遨游大海不会迷航鲸的种种用处对人是很有好处的，现在鲸大量的死亡，使人类也走向灭亡，我们要保护鲸类，让它们继续生栖繁衍。让人们根据它们的好处，制造出更先进的仪器，鲸是人类的朋友。鲸每天都睡觉.睡觉时,总是几头聚在一起,要是有响声,它们就四散游开.鲸可以活几十年或一百年.
