视频后面有更多细节
Details after the show.
没错 这只马陆正在发出光亮
Yep, this millipede is glowing.
捕食者可能会在月光下看到那个超凡脱俗的光晕
That otherworldly aura is what a predator might see under the moonlight.
我们的眼睛还没那么敏锐
Our eyes aren’t sensitive enough to see it
在没有特殊紫外线灯的情况下还不能看到它
without using a special UV light.
这光芒是一种预示:
The glow is a head’s up:
这只马陆正在准备制造致命的突袭
this millipede is packing a lethal surprise.
当落日余晖洒在旧金山东部的山丘上时
When dusk falls in the hills east of San Francisco,
这种学名为Xystocheir dissecta的马陆
Xystocheir dissecta millipedes emerge
从它们的地下避风港出来觅食
from their underground havens to go foraging.
尽管长了那么多条脚 它们仍然走得很慢
Even with all those legs, they’re kinda slow.
如果你是一只饥饿的鸟 青蛙或者蜘蛛
If you’re a hungry bird, frog or spider,
在你眼中 马陆就像是一道美味大餐
a millipede looks pretty yummy.
所以 该马陆来防守了
So, time for defense.
大多数种类的马陆会把自己蜷缩成一个球
Most millipedes curl up into a ball.
但这名为Zystocheir dissecta的马陆却把防护措施提高了一个档次
But Zystocheir dissecta takes it up a notch:
它将和敌人来一场化学战
it unleashes chemical warfare on its enemies.
看到这些小洞了吗?
See those little holes?
它们是防御腺孔
They’re ozopores.
这些腺孔能分泌一种隐形却致命的气体
They secrete an invisible, deadly gas:
氰化氢
hydrogen cyanide.
氰化物会阻碍细胞吸收氧气
Cyanide blocks cells from using oxygen,
基本上 中招者都会窒息而死
essentially suffocating their victims.
马陆释放的毒气足以杀死一只鸟或者老鼠
The millipede can spray enough to take down a bird or a mouse.
所以 大部分的小动物都想离它远远的
Yeah,so most critters want to be far away.
越远越好
Really far away.
马陆对自身的毒气已经产生了免疫力
The millipedes have developed an immunity to their own toxin,
所以它们不会受毒气影响
so they’re unaffected.
但是有一种小甲虫同样对这种毒气具有免疫力
But there’s one tiny beetle that’s developed an immunity to the gas too,
也就意味着它们可以抵御马陆那致命的毒攻
which means it can take the millipede’s impressively noxious attack.
对Promecognathus crassus这种甲虫来说
For Promecognathus crassus,
马陆是它们最爱的食物
millipedes are their favorite food.
等等 真的吗?
Wait, really?
马陆几乎是甲虫的五倍大
The millipedes are like five times bigger,
而且周身覆盖着铠甲般的甲壳
and covered in armored plates.
但是甲虫有着长长的 像剪刀一样的下颚
But the beetle has these: long, scissor-like jaws.
狩猎开始了
The hunt begins.
甲虫先跳到马陆背上
The beetle jumps on
然后如驯服野马般骑在马陆身上
and rides the millipede like a bucking bronco.
随后 甲虫用它们的长下颚从背后夹住马陆的头
Then it clamps down behind the millipede’s head,
在扭打中慢慢使马陆屈服
slowly wrestling it into submission.
之前有些科学家认为甲虫试图切断马陆的神经
Some scientists thought the beetle was trying to sever its nerves
从而使马陆不能释放氰化物
so it can’t release cyanide.
这现在是他们认为解决这个大家伙的唯一办法
Now, they think it’s just the only wayto take down the giant.
不管怎么说 这些氰化物的攻击没有起到任何作用
Either way, those blasts of cyanide gas aren’t doing anything.
这只马陆尝试第二种方案:紧紧蜷缩自身
The millipede tries plan b: curling up tightly
但这场混战吸引了另一只想要分杯羹的竞争对手
But the scuffle has attracted a rival who wants the feast for itself.
但是 后到的甲虫却没那么幸运
The latecomer is outta luck, though.
这只顽强的甲虫已经咬进马陆的身体
This tenacious beetle has dug in.
它正将马陆锯开 试图将头切下
It’s sawing away, trying to take the head clean off.
然后 它就可以享用马陆多汁的内脏
Then, it can devour the juicy innards.
根据加利福尼亚大学伯克利分校的研究者们的说法
According to researchers at the University of California, Berkeley,
这只甲虫是第一只记录在案的
this beetle is the first documented case
可以免疫氰化物的捕食者
of a predator being resistant to cyanide.
这恰恰说明 在生物军备竞赛中
Just goes to show – in a biological arms race,
没有谁能一直处于生物链的顶端
you’re never on top for long.
