微观深望
Deep Look
如剃刀般锋利的刺 用来刺敌人
Razor Sharp. Designed to impale.
敌害若被刺中 便很难移除
And next to impossibleto remove.
这不是那种会运用上述武器的令人害怕的动物吗?
The fearsome creature that wields these weapons?
哦!看看它的脸
Aw! look at that face.
北美豪猪可能行动缓慢 她慢慢悠悠的行进
A North American Porcupine may be slow, as she plods along
但她不需要着急
she can take her time,
寻找美味的叶子或树皮作为食物 或咀嚼橡子
looking for tasty leaves and bark or munching on acorns.
她可没有什么好担心的
She doesn’t have much to worry about
因为她身上长着30000根极为锋利的刚毛
That’s because she’s packing 30,000 piercingquills.
等等 那些白色的东西并非刚毛
But hold on, those white things aren’t quills,
这些只是长出来的长毛
they’re just extra long hairs,
是让她看起来更尖锐的圈套
decoys to make her look even more spikey.
真正的刚毛藏在下面
The real quills are underneath.
它们也是白色的 但通常藏在黑毛里面
They’re white too, but usually hidden underthat dark fur.
大多数动物懂得 不要轻易去惹豪猪
Most animals learn – do not mess with porcupines.
一般情况下 豪猪通常将它的刚毛保持平整 顺着自己的身体
A porcupine normally keeps its quills flatagainst its body.
一旦感受到威胁 刚毛便会直竖起来
But when threatened, it bristles,
调转屁股 露出棘刺长得最浓密的地方
showing off an area on her backside where the quills
这块可以称之为“棘刺丛”
are the densest, called the rosette.
这些棘刺还会发出臭味
And it stinks.
其刚毛上覆盖着一层厚厚的油脂
The quills are coated in a thick grease that puts
散发出来的气味既刺鼻 又带麝香味 为豪猪所独有
off a pungent, musky smell, unique to porcupines,
这种味道使敌人退却
that says “back off.”
但若这依然抵抗不了敌人
But if that’s not enough…
她便会用自己的尾巴猛击靠近她的任何东西
She uses her tail to slap anyone who getstoo close.
看看这个
Watch this…
她不会“射”出她的尖刺 那只是谣言而已
She didn’t shoot her quills out – that’sa myth.
尖刺不会轻易被射出来
The quills don’t release easily
除非豪猪们撞到了什么东西或者尖刺先受到推动
Unless they hit something or get pushed in first.
这些尖刺极为锋利 比皮下注射器的针头还要锋利
They’re super sharp – sharper than thishypodermic needle.
我们来看看刺头
And check out the tip –
它上面长着朝后的倒刺 用显微镜才可看见
it’s covered in microscopic, backward-facing barbs.
当你试图将刺头移除 上面的倒刺便会呈扇形展开
When you try to remove it the barbs fan out,
使得刚毛卡在里面
keeping the quill lodged in.
唉哟
Yowch.
如果你的一些部位如嘴巴不幸被刺到
If you get them in an unlucky sport, like your mouth,
日子就很难过了 你懂的
That makes it hard to, you know…live
虽然棘刺会让你疼痛难耐
But even though they’re super painful,
但是这通常不会导致感染
getting stuck with a quill doesn’t usually lead to infection.
刚毛上面覆盖的油脂就是天然的抗生素
The quill’s grease acts like a natural antibiotic,
可抑制某些危险细菌的生长
inhibiting the growth of some dangerous bacteria.
也可能是因为豪猪太过笨拙
Maybe it’s because porcupines are actuallypretty clumsy.
从树上掉下来时 它们总是会不小心刺到自己
They’ve been known to accidentally quill themselves, falling out of a tree maybe.
哈佛大学的研究者正从这些刚毛中寻找灵感
Researchers at Harvard are now looking atthese quills for inspiration.
医生用来缝合伤口的外科钉
Surgical staples that doctors use to close wounds curve
扎进肉里 留在体内
in under the skin to stay put.
扎进去的时候 便会给肉体造成伤害
That causes damage on the way in
并且为细菌留下生长的空间
and leaves room for bacteria to take hold.
那么做一个像豪猪的刚毛般带有倒刺的外科钉如何呢?
So what about a staple with barbs like a porcupinequill?
这种外科钉将使得伤口更小 不用弯曲便可以固定住
It could make a smaller wound and stay putwithout curving.
此外 还可防止感染 加快伤口愈合
That could keep infection out, and speed uphealing time.
随后它便会溶解
Then it just dissolves.
聪明得很 不是吗?
Pretty sharp, right?
这便说明了为什么这个浑身带刺的小毛球可以博得任何人的喜欢
That’s something about this spiky, littlefuzzball that anyone could love.
