看蜘蛛横空射出25米网

Spider Shoots 25 Metre Web | The Hunt | BBC Earth

It’s called Darwin’s bark spider.
它叫达尔文树皮蛛
And the female has a remarkable strategy.
雌性达尔文树皮蛛有个绝妙的策略
Like a real-life Spider Woman,
她就像一个现实版的蜘蛛女侠
she sprays strands of silk in one long continuous flow.
能喷射出一股长长的连续的蛛丝
The threads fan out like a sail
这些丝像帆一样成扇形散开
and drift on air currents blowing across the water.
随着拂过水面的风而飘动
Every few seconds she crimps the strands together
每隔几秒钟 她就把丝缕聚拢起来
to stop them spreading too widely.
防止它们散得太开
The breeze will do the rest.
剩下的工作就交给微风啦
Blowing the threads into a single line
微风将丝线吹成一股
and a 25-meter bridge.
长达25米的桥
Now, she will reinforce her bridge
现在 她将加固这座桥
because her web will hang from it.
因为她的网要结在上面
But there’s something bouncing the line at the other end.
但这条丝的另一端有东西在震动
Another Darwin spider is trying to take advantage of her hard work.
另一只达尔文树皮蛛企图霸占她辛劳的成果
She must deal with the intruder head on.
她必须直面迎战入侵者
The cut line is an inconvenience
线被割断了 这带来很大的不便
but no more than that.
但仅此而已
With hooks on the tips of each leg,
她用每条腿末端的钩子
she gathers in the thread.
把丝收拢起来
It won’t go to waste,
这些丝不会浪费掉
as she’ll eat it later.
因为待会儿她会把它吃掉
When it’s all reeled in,
把丝都绕拢之后
she sprays again.
她又开始吐丝了
Out streams another 25-meter bridging line.
她又喷射出一段25米长的蛛丝桥
How a spider no bigger than the thumbnail
一只不过拇指甲大小的蜘蛛
could produce so much silk so quickly
居然能如此快速地造出这么多丝
has baffled scientists.
这着实让科学家们困惑不已
And it’s no ordinary silk.
并且 这不是普通的丝
It’s the toughest natural fiber on the planet.
它是地球上最结实的自然纤维
Tougher than steel.
比钢铁还结实
And it needs to be tough to span the wide river.
而且为了跨越宽阔的河道 它也需要足够结实
With the bridge taut
蛛丝桥绷紧了
and the ground anchor in place,
地面的支撑点也已牢靠
it’s time to construct her trap.
是时候搭建她的陷阱了
These spiders can build the world’s largest orb webs,
这些蜘蛛能够建造世界上最大的球状网
up to 2 meters wide.
宽达两米
A few hours from the first spray of bridging line,
距喷射第一缕蛛丝桥已经过了几小时
the job is done.
准备工作完成
Now, her strategy is simple.
现在 她的策略很简单
Sit and wait.
坐等
And there’s one final bout of silk production.
只需再吐最后一次丝了
Shrink-wrapping her food for later.
收裹好食物 以备后用
