动物的生死友谊

  ①动物世界是一个神奇的世界。弱肉强食是动物界的自然法则,强者和弱者之间似乎天生就是一种“水火不相容”的关系。但是令人难以相信的是,它们之间居然也能朝夕与共,和睦相处。  

       ②非洲蜜獾是一种孤独的动物,经常独来独往。但是因为它喜食蜂蜜,和一种褐色小鸟--响蜜鸟结下了“甜蜜的友谊”。一个找蜜,另一个挖蜜,然后共同享用。在非洲,很多蜜蜂都选择在地上建巢。当响蜜鸟发现蜂巢以后,就会向蜜獾的洞飞去,发出一种特殊的叫声。一听到这种呼叫信号,蜜獾就立即钻出洞来,在响蜜鸟的带领下向蜂巢跑去。蜜獾的毛又密又厚,所以蜜蜂奈何不了它。很快蜜獾就把蜂巢挖开了,一股脑儿将蜜和蜜蜂的幼虫全部吃掉,最后把空蜂房留给响蜜鸟。而响蜜鸟想要的正是空蜂房——蜂蜡。在响蜜鸟的嗉囊里有许多共生菌和酵母菌,这些菌类能分解蜂蜡,把它变成脂肪,从而使机体能够吸收。  

       ③然而,并非仅仅为了“嘴馋”的共同利益才使动物们联合起来,有时是安全的需要,把一些不同的动物牵扯到一起。  

       ④在中美洲有一种文鸟,这种小鸟会编织很复杂的巢,巢的样子就像一个罐子吊在树枝上。在热带,有猴类、野猫、蜥蜴、蛇等,它们都善于爬树,所以鸟类想要保全自己的后代不受侵害很困难。不过,那些凶恶的动物并不敢冒险爬进文鸟的“罐子”里,因为它常常把巢安置在黄蜂巢旁边,正是黄蜂巢--这个可怕的大球在保护着小鸟。有趣的是,黄蜂从不得罪自己的邻居,而对侵犯小鸟的各种敌人却毫不留情。  

       ⑤从昏黑的深海,到充满激流的岸边,到处都有寄居蟹。寄居蟹可以栖息在任何腹足类的贝壳里。如果没有空贝壳,寄居蟹就会发起进攻,把“主人”一块块地从“房子”里撕扯出来,自己移进去,然后它就用一只螯堵住贝壳的入口。可是海洋中有些凶猛的动物并不害怕寄居蟹的大螯。比如章鱼就不怕,章鱼用有力的“手腕”很容易“破门而入”,把寄居蟹从贝壳中拉出来。为了防范“强盗”的进攻,寄居蟹备有一种特殊的武器,那就是寻找海底的“毒花”——海葵,并和海葵在一起生活。海葵的毒性很大,一点儿海葵毒汁就可以毒死一只美洲虎。海洋里的动物对海葵都尽量远远地避开,它们都害怕这些“毒花”。但寄居蟹并不害怕,因为海葵可以成为它们的义务卫士。  

       ⑥科学界已知有400多种寄居蟹,但它们与海葵的关系各不相同。比如,真寄居蟹和疣海葵的关系可以说是相依为命。如果把它们分开,疣海葵两三个月就会死掉,而真寄居蟹因为得不到疣海葵毒汁的保护,过不了几天就会被贪婪的螃蟹或章鱼吃掉。所以真寄居蟹往往把海葵放在“门槛”上——在接近贝壳入口的下面。疣海葵的毛孔就好像是堡垒的枪眼一样,从那里可以飞射出毒“箭”,射伤那些侵犯真寄居蟹的敌人。而疣海葵的嘴正好在真寄居蟹的后面,当蟹吃东西时,疣海葵也就随着一起就餐——用触手去抢被真寄居蟹扯碎的食物。  

       ⑦动物之间友谊与合作的故事几乎是讲不完的,这些故事是那么动听、奇妙,其中的奥秘正等待着科学工作者去探索、去揭示。
