白鳍豚英文简介
白鳍豚(bái qí tún),在长江里大约生活了2500万年的白暨豚,是中新世及上新世延存至今的古老孑遗生物。白暨豚是鲸类家族中小个体成员,是世界上现有5种淡水豚(拉河豚、亚河豚、恒河豚、印河豚、白暨豚)中存活头数最少的一种。由于数量奇少,白暨豚不仅被列为中国一级保护动物,也是世界12种最濒危动物之一。原属淡水豚科,20世纪70年代末,根据中国科学家周开亚教授的建议,单独设立了白暨豚科。 鲸目白暨豚科白暨豚属的唯一种。

白鳍豚的体形呈纺锤形,身长约2-2.5米左右,体重可达200千克以上。嘴部又长又细,背呈浅灰色或蓝色,腹面为纯白色,背鳍形如一个小三角,胸鳍宛如两只手掌,尾鳍扁平,中间分叉,善于游水,时速可达80千米左右。由于长期生活在浑浊的江水中,白暨豚的视听器官已经退化。它眼小如瞎子,耳孔似针眼,位于双眼后下方。但大脑特别发达,声纳系统极为灵敏,头部还有一种超声波功能,能将江面上几万米范围内的声响迅速传入脑中。一旦遇上紧急情况,便立刻潜水躲避。白暨豚耐寒,体温通常在36℃左右。

编辑本段分布范围

白鳍豚主要生活在长江中下游及与其连通的洞庭湖、鄱阳湖、钱塘江等水域中,通常成对或10余头在一起,喜在水深流急处活动。现有数量稀少,20年前的估计只有300头左右,当时就已面临灭绝的危险。

编辑本段生活习性

白鳍豚喜欢群居,尤其在春天交配季节,集群行为就更明显。每群一般2-16头。其活动范围广,但对水温条件要求较高,经常在一个固定区域停留一段时间,待水温条件发生改变后,又迁入另一地域。以鱼类为食。

白鳍豚喜欢生活在江河的深水区,很少靠近岸边和船只,但它时常游弋至浅水区,追逐鱼虾充饥。它的吻宽细长,上下颌长有130多枚圆锥形的同型齿,可它却懒得咀嚼,只管张口吞下鱼食,消化能力很强。白暨豚往往成对或三五成群一起活动,但人们很少有机会看到它,只有在它露出水面呼吸时才能瞥见一眼。

白鳍豚分布在长江中下游干流的湖北枝城至长江口约1600千米的江段内,以鱼为食,喜结群活动,小群约2~3头,大群约9~16头。白暨豚是用肺呼吸的水生哺乳动物,每次呼吸时,头顶及呼吸孔先浮出水面,接着露出背部和低三角形的背鳍,出水呼吸时间约1-2秒钟,潜水时间每次约20秒,长潜时可达200秒。成熟个体最大体长,雌性2.5米,雄性2.3米,体重100~150千克,有恒定体温,总是在36摄氏度左右。

编辑本段繁殖习性

白鳍豚两年繁殖一次,每胎1仔,出生时体长80厘米左右。新生幼体体色略深.成年白暨豚一般背面呈浅青灰色,腹面呈洁白色,在阳光的照耀下尤其光亮。水平伸展的鳍肢和尾鳍上下两面分别与背面和腹面同色,这样的颜色分布恰好与环境颜色相符。当由水面向下看时,背部的青灰色和江水混为一体很难分辨;当由水底向上看时,白色的腹部和水面反射的强光颜色相近也很难被发现。这使得白鳍豚在逃避敌害、接近猎物时,有了天然的隐蔽屏障。白暨豚寿命可达30多年,雌兽一般在6岁达到性成熟,雄兽为4岁。成年白暨豚每年 *** 两次,分别在3月至5月,8月至10月。孕期为10至11个月,一胎一仔,偶有两仔。野生状态下,成年白鳍豚雌雄比例为1:1,但雌兽怀孕率一般仅为30%,自然繁殖率很低。

每年的冬末春初是白鳍豚的交配期,母豚妊娠期长达1年左右,因此产仔大多在来年的春季。出生后的小白鳍豚靠母亲的乳汁喂养,直到五六岁才算成熟;一般寿命30年。

白鳍豚是食肉动物,口中约有130个尖锐牙齿,为同型齿。常在晨昏时游向岸边浅水处进行捕食,一般以整条吞食体长小于6.5厘......>>
