极速猎杀（2013）

比F1赛车更加迅捷
Faster than a formula one race car...
如火箭推进器般雷霆万钧
More thrust than a space shuttle's rockets...
让战斗机相形见绌
And maneuvers that put fighter jets to shame...
世界上最迅猛的动物
The fastest animals on the planet
依靠其速度来捕食
Use speed to kill.
高速摄像机与尖端电脑动画
High-speed cameras and state-of-the-art cgi
将展示它们的拿手绝技
Uncover how they do it.
在黑泻湖的水下世界中
In the underwater world of the black lagoon,
进化促使动物们
Evolution has created
创造出惊人数目的狩猎方式
A staggering variety of ways to kill.
这些奇特的暗♥杀♥者镇定地等待着突击的时机
Freakish assassins are poised to strike,
通过穿刺、射击和颚部完成狩猎
Using spears, bullets, and alien jaws.
生死狩猎场
A world of action is hiding
隐于一瞬之间
In the blink of an eye.
泻湖是一个介于海和湖之间的奇特的地狱般的生态系统
A bizarre netherworld between ocean and river,
这种生态系统在亚马逊和非洲尤为多见
Lagoons are found from the amazon to africa,
并存在于其他地区
And everywhere in between.
连湖边的地貌都似乎由着自己的方式变化着
Even the landscape seems to have a life of its own,
看似平静的表面下 实则暗流涌动
Bringing constant turmoil to this seemingly peaceful place.
生活在这里的生物以进化适应变化
The creatures here evolved to cope with change,
毕竟他们活在一个物竞天择 生死未卜的世界中
Living in a world where death is the only certainty.
月亮绕地球公转导致的潮汐
The moon is responsible for the tidal changes
造就了这个静若处子 动如脱兔的泻湖
That create this two-faced lagoon.
一天的两次潮汐
Pulling tides in and out twice a day...
亘古不变
Relentlessly.
匕♥首♥般的潮浪漫过湖边沙地
Daggers push through the sand--
使得这片毫无生气的湖陆交界处长出了大量的红树林
The deadly welcome mat to a sprouting mangrove forest.
红树林的根盘根交错
Underneath the water,
在水下打造了一个鱼类生存最理想的迷宫般的栖息之处
Mangrove roots create a maze ideal for fish nurseries.
鱼类来这里寻求庇护
They come here for protection,
而掠食者们把这里当做狩猎场
But others are here to hunt.
红树林的树荫下匍匐满了芸芸众生
The shady mangroves crawl and creep with life,
看起来这里比起那危机四伏的水下世界是安全的
Seemingly safe from the horrors that lurk underwater.
但是在黑泻湖域 危机无处不在
But in the black lagoon, nowhere is safe.
射水鱼是个敏锐的捕手
This archerfish is a sharpshooter.
射水鱼（archer fish）是印度洋-太平洋地区鲈形目射水鱼科5种鱼的统称
以其能从口中射出水滴，射猎水面悬垂植物上的昆虫为食而闻名世界。
这片红树林根的迷宫是射水鱼首选的狩猎场所
The mangrove maze is its prime hunting ground,
箭无虚发
And to hunt here successfully
射水鱼必须使出一些出乎猎物意料的狩猎方式
He's had to evolve some creative ways to kill...
它们利用红树林根为自己打掩护
Taking advantage of the cover that the mangrove roots provide,
静候它的猎物走出安全地带
He targets prey completely out of his watery realm...
比如这只螳螂
Like this cockroach,
丝毫不知它已经被瞄上了
Clueless he's being stalked.
射水鱼最后一跃注定了它的生命到此为止
A lethal leap seals his fate.
强有力的尾鳍
A powerful tail
为射水鱼弹入空中提供力量
Propels the archerfish into mid air...
速度叹为观止
So fast,
昆虫连挣扎逃跑的时间都没有就成了他人盘中餐
The insects don't have time to even attempt an escape.
狩猎的成功依赖于
This incredible burst of speed
突然爆发出的惊人速度和超凡的伪装技术的合二为一
Can only work hand in hand with exceptional camouflage.
鱼身上白色的底色和黑色斑点
Its white body and black spots
这使它完美地和湖面上斑驳的红树林的树荫融为一体
Blend perfectly into the dappled shade of the mangroves,
它纤细的身体体表面♥积♥很小
While its slim body has a small surface area
因此从上方是很难察觉到射手鱼的存在的
And is difficult to detect from above.
对于处于水面上方的六腿爬行昆虫来说
For the six-legged creepy crawlies on the topside,
狩猎者可以说是隐形的
The hunter is practically invisible.
但是射水鱼能成为一个伟大的捕手
But it's not only camouflage
不仅仅是它高超的伪装技术
That makes it a great hunter.
声音和味道并不能从空气中传入水下
Sound and smell don't cross the air-water interface,
所以射水鱼必须依靠它们的视觉
So these fish must depend on their vision
来寻找它们的猎物并且精准的捕获猎物
To find and accurately grab their prey.
射水鱼的眼睛
The archerfish's eyes
离它的嘴巴很近
Are positioned close to their mouths,
这使得它们拥有绝佳的双眼可视区
Giving them fantastic binocular vision.
它们用眼部的不同位置
They see colors differently
所见的颜色是不一样的
In different parts of their eyes.
在他们眼球的上方有视色素
They have visual pigments tuned to the murky brownish waters
当它们向下看暗浊的水下世界
In the upper part of their eye
光线进入眼睛后正好在这块区域成像
that looks downwards
它们的眼球下方有和人类非常相似的色觉区
And normal color vision, much like humans',
当它们向上看瞄准猎物时
In the part of the eye that looks up
光线进入眼睛后在色觉区成像
And towards potential targets.
如果你认为射水鱼的跳跃给你留下最深刻的印象的话
If you thought jumping was impressive,
那接下来的一定会让你大开眼界
You ain't seen nothing yet.
当跃出水面捕食这招不管用的时候
When jumping doesn't cut it,
射水鱼就会化身为水下水枪
The archerfish turns into a submarine water pistol
它们可以喷射出强有力又精准的水柱
And can spit out a strong and accurate jet of water
迫使昆虫离开它们的安全高地
To dislodge insects from their lofty perch.
它们用舌头抵在
With their tongue against the groove
口腔上部的凹槽处
On the roof of their mouth,
这样就形成了一段管子
They form a tube
然后通过迅速地鼓动鱼鳃 从而喷出水柱
And force water out by snapping shut their gills.
它们可以通过控制舌尖的位置来操控水柱的方向
They can direct the jet of water with the tip of their tongue,
它们甚至还考虑了
Even taking into consideration
水柱由于重力所产生的弧度
The arc of the water bullet due to gravity.
准备 瞄准 喷射
Ready, aim, and fire.
这些红树林里中有许多射手们通常会聚集在一起
These mangrove marksmen often form shooting parties
相互掠夺对方的食物
And will steal each other's prey.
射水鱼也是这样
The archerfish is one of a kind.
射水鱼是世上唯一一种使用水柱捕食的鱼类
No other fish on the planet uses a jet of water to hunt.
正中靶心
Bull's-eye.
穿过红树林树下昏暗的湖泽
Beyond the dark alleyways of the mangrove,
在泻湖湖底多叶的四周
In the leafy suburbs of the lagoon,
一只青梭子蟹刚刚完成了交♥配♥
A blue swimming crab has just finished mating.
随着扁平浆状附肢的摆动
With the help of swimming paddles,
它此刻正在觅食
He's now on a search for food.
但由于无处可做掩护
But with no place to hide,
它很容易就成了狩猎者们瞄准的猎物
He's an easy target for predators.
头顶上的天空才是它所要担忧的
And it's the sky above him he needs to worry about.
不知从何处 来自空中的暗♥杀♥者发起了攻击
Out of nowhere, an aerial assassin strikes.
这只螃蟹幸运的躲过一劫
The swimmer crab has made a lucky escape...
暂时 虎口逃生
For now.
这是非洲海雕
This african fish eagle,
美洲秃头雕的近亲
Cousin to the american bald eagle,
把它的狩猎范围定在了
Stakes her claim to a half a square mile
黑泻湖湖岸半平方英里左右的地方
Of the black lagoon's shoreline--
这片地方是它首选的狩猎场所
Prime hunting ground.
马上就要退潮了
The tide is moving out,
这使得鱼和甲壳类动物
Leaving the fish and crustaceans
无处可藏
With fewer places to hide.
到了非洲海雕狩猎的时间了
It's her time to hunt.
它看到身旁的猴子
Monkeys aside,
以它超凡的视力
Her spectacular vision allows the fish eagle
让它能定位到一英里之外的猎物
To pinpoint prey over a mile away,
甚至是在泻湖水底的猎物都能看到
Even beneath the lagoon's surface.
人们相信
It is believed
鹰的视距是人类的5倍之远
That eagles can see five times further than humans,
这要归功于鹰的视网膜上
Thanks to retinas that are densely coated
密集地布满了叫做视锥细胞的光感细胞
With light-detecting cells called cones.
同时 他们的视网膜中心窝较之人类更深
They also have a much deeper fovea--
视网膜中心窝是处于眼的后部
A cone-rich structure in the back of the eye
能产生数倍放大的一种结构
That provides extra magnification.
它虽然叫鱼鹰
She may be called a fish eagle,
但这个机会主义的捕食者
But this opportunistic predator
几乎会猎捕所有进入它视野的生物
Will eat almost anything that catches her eye.
它发现什么了
She sees something.
它必须得快点
She's got to be quick.
如果它的猎物在被捕获之前就先先发觉猎手的话
If her prey spots her before she can catch it,
猎物就会沉入非洲海雕所不能企及的黑泻湖深处
It'll swim to the unreachable depths of the black lagoon.
它那对展开长达8英尺的双翼
A powerful 8-foot wingspan
