Which makes sense.
这种解释是有道理的。
In a paper just published in Naturwissenschaften, though, Dr Aisenberg and her colleagueGilbert Barrantes at the University of Costa Rica report that female Leucauge argyra gofurther: they create plugs all by themselves.
但Aisenberg博士与她的哥斯达黎加大学同事Gilbert Barrantes在《自然科学》杂志上新发表的论文指出: 长角银腹 雌性蜘蛛还有一手更绝妙的高招:她们能自行分泌封堵粘液。
And that really is odd.
这就真的让人觉得奇怪了。
Because plugging is in a male s interest, he should never leave it just to the female.
因为封堵行为是对雄性蜘蛛有利的事情,他怎么会将这种特权拱手让给雌性蜘蛛单独完成呢?
Except that in this case the plug turns out to be very much not in a male s interest.
除非有这种情况出现,即封堵行为会对雄性蜘蛛有非常不利的影响。
In fact, it can kill him.
事实上,这种让权造就了雄性蜘蛛的死亡。
Spider sex is unusual in that males transfer their sperm to the female on small limbs calledpedipalps.
蜘蛛的交配方式与众不同,雄性蜘蛛利用称做 须肢 的小肢干将精液输送给雌性蜘蛛。
