动物世界中充满了各种壮丽的奇观
The animal world is full of spectacle and wonder.
但身处其中又会是怎样一番感受呢
But what's it like to be right in the heart of the action?
为此我们派出了间谍小组潜入其中
To find out, our team of spy creatures goes undercover.
它们不仅在外形上栩栩如生
They not only look like the animals they film...
行为举止也惟妙惟肖
..they behave like them, too.
它们配备了最先进的拍摄技术
Armed with the latest camera technology...
向着全世界进发

从炙热的热带区域

到广阔的北方大地
..to the lands that lie in the north.
从南部海域的岛屿
From the islands of the Southern Seas...
到漫天冰雪的极地冻土

在这一次的任务中 我们的动物间谍们
On this assignment, our spy creatures
将揭示南半球海岛上生机勃发的奥秘

由于远离大♥陆♥
Far from the mainland,
这些与世隔绝的地方
these isolated places
孕育了地球上某些最独特的生物
have given rise to some of the most unique animals on Earth.
太平洋中的加拉巴哥群岛
The Galapagos Islands of the Pacific Ocean.
这片贫瘠的的群岛
A barren archipelago
是三百多万年前
formed by underwater volcanoes
由海底火山形成的
over three million years ago.
将这片熔岩地貌视为家园的
This landscape of lava is home to
是只能够在这里被发现的奇特动物群
a remarkable fauna found nowhere else in the world.
其中最有趣的动物之一
One of the most intriguing
就是海鬣蜥
is the marine iguana.
这些冷血蜥蜴
Before they can become active,
必须晒足太阳
these cold-blooded lizards
才能变得活跃起来
must bask in the sun.
它们用黑色的皮肤吸收阳光的热量
Their black skin absorbs the heat,
将它们的核心体温
raising their core temperature
提升至高达四十摄氏度
to a toasty 40 degrees.
为了拍摄这些受到高度保护的动物
To film these highly protected animals,
间谍鬣蜥获得了特别许可
Spy Iguana has special permission
可以比任何人类都更接近它们
to go closer than any human is allowed.
想要成功完成任务 它必须伪装得像模像样
To succeed, it has to be totally convincing.
一旦身体变得足够暖和
Once they are hot enough,
它们便开始行动了
they start to move.
间谍鬣蜥
Spy Iguana
正在目睹一场壮观的景象
now witnesses something remarkable.
一场属于蜥蜴的悬崖跳水运动
Cliff jumping for lizards.
它们是为了去吃
They are after the seaweed
生长在近海的繁茂海草
that flourishes just off shore.
它们的时间很紧迫
They're on borrowed time.
海水温度很低
The water's cold.
它们的体温
And in less than an hour,
在三十分钟内就会降低一半
their body temperature will halve
那时它们就必须返回岸上
and they'll have to return.
现在 由另一名间谍接手任务
Now, another spy takes over.
伪装成火山岩的摄像机可以
Lava Cam can track the iguanas
追踪它们到任何地方
wherever they go.
每年的这个时候
At this time of year, the females
雌性鬣蜥会开始在海滩上产卵
are laying their eggs on the beach.
沙子被晒得滚烫
The sand is baking hard,
但在一米之下
but a metre down
却有适合孵化的完美温度
it's the perfect temperature for incubation.
间谍鬣蜥加入了它们的行列
Spy Iguana joins them
以便近距离观察
for a closer look.
挖好一个孵化巢需要一个小时
Digging the nest can take an hour.
在烈日之下更为艰辛
Hard work in the hot sun.
在它们休息的时候
When they take a break,
会扣上自♥制♥的太阳帽
they have a self-styled sun hat.
我们的间谍也自♥制♥了一顶
Even our spy.
对最佳育婴地点的竞争异常激烈
Competition for the best nest sites is intense.
正在挖巢的鬣蜥必须时刻准备捍卫领地
Those digging must be prepared to hold their ground.
上下抖动头部是在向主人提出挑战
Head bobbing is a challenge for ownership.
通过一番角力
The winner is decided
来争夺所有权
by a test of strength.
原领主获胜
The owner wins.
它可以继续完成剩余的工作了
She's free to finish her work.
放眼潮汐线
Along the tide line,
其它鬣蜥在参加完海底盛宴后
the others are returning
正陆续归来
from their underwater feast.
经过冰冷海水的降温
Chilled through by the cold sea,
它们必须再晒一次日光浴
they must sunbathe once more.
当间谍鬣蜥跻身其间时
As Spy Iguana joins them,
另一番趣景上演
another surprise is in store.
它们开始喷射鼻涕了
They sneeze snot.
它们鼻腔里的特殊腺体
Special glands in their nose
能将多余的盐分排出体外
remove excess salt,
而排出方式很是惊奇
which is expelled spectacularly.
它们能做到的
Whatever they can do,
我们的间谍也能做到
our spies can do, too.
这个还是算了吧
Oh...perhaps not.
随着一天接近尾声
As the day ends,
鬣蜥们表现出了它们温情的一面
iguanas show their more affectionate side.
甚至我们的间谍也赢得了一位追求者
Even our spy has an admirer.
当落日的余辉
Snuggling together
掠过加拉巴哥群岛时
preserves precious warmth,
它们依偎在一起
as the sun sets
以保持珍贵的体温
over the Galapagos Islands.
在八千多英里之外
Over 8,000 miles away,
澳大利亚南海岸的附近
off the southern coast of Australia,
袋鼠岛是另一个独特的野生动物天堂
Kangaroo Island is another unique wildlife haven.
这里与大♥陆♥分离长达一万年
Cut off from the mainland for 10,000 years,
岛上甚至进化出了独有的袋鼠品种
it even has its own variety of kangaroo.
树袋熊也在这里生存
Koalas are here, too.
但它们相对来说算是新移♥民♥
But they are relative newcomers.
在一百多年前被引进后
Introduced here 100 years ago,
它们一直生存至今
they now survive
种群数量异常庞大
in unrivalled numbers.
混迹于它们之间的
Among them is a new koala,
是一只刚从大♥陆♥到来的树袋熊
fresh from the mainland.
它来此是为了
It's here to film
拍摄树袋熊的繁育行为
their breeding behaviour.
时机正好
The timing's perfect.
它们刚刚睡醒
They're just waking up.
打哈欠可以让大量氧气涌进大脑
Yawning pumps oxygen to the brain.
尽管精神抖擞
Even wide awake,
但也不需要进行长途跋涉
he needn't go far.
它最爱的食物就在身边
His favourite food is all around him.
桉树
Eucalyptus.
但桉树叶不仅坚韧
But their leaves are not only tough,
而且有毒
they are poisonous,
所以树袋能进化出了极为强效的消化液
so koalas have powerful digestive juices
能够中和树叶中的毒素
that neutralise the toxins.
仅是消化掉这些食物就能耗光它们的精力
Just digesting their food saps energy,
所以它们每天至少要睡二十三个小时
so they sleep up to 23 hours a day.
但今天这只树袋熊
But today, this koala
一反常态
is breaking the habit.
在繁殖季节
In the breeding season,
它必须加倍打起精神
he must step up a gear.
我们的移♥动♥间谍摄像机
One of our mobile spy cams
必须随机应变
must rise to the challenge.
树袋熊极少到地面活动
Koalas rarely come to the ground
更不用说像这样暴走
or show such a turn of speed.
但现在它需要捍卫自己的领地
But he now has a territory to defend.
它用咆哮来宣告自己的主♥权♥
He bellows to announce he's in charge.
这是对其它雄性的警告
A warning to other males.
