小小世界（2020）

地球如此壮观
Planet Earth is so spectacular,
以至于生命中的小事物很容易被忽视
it's easy to miss the smaller things in life.
但如果仔细看看
But take a closer look...
你将会发现一个完全未知的世界
and there's a whole undiscovered world.
这个世界中的微型英雄
A world where tiny heroes...
和小怪兽们
and little monsters...
需要无比强大的超能力
need incredible superpowers...
才能在险象环生中存活下来
to help them triumph against giant odds.
加勒比海地区
The Caribbean.
(旁白 保罗路德)
这里看起来就像天堂
It looks like paradise.
似乎是古巴吸蜜蜂鸟温馨的家
And it seems a pretty nice home for the Cuban bee hummingbird.
它比一只蜜蜂大不了多少
Not all that much bigger than a bee.
是世界上最小的鸟类
It's the smallest bird in the world.
这里有各种稀奇古怪的动物
There are all sorts of little castaways
生活在这些岛屿上
that have found their way to these islands.
很多都是同类中体积最小的 不存在于地球上其他地区
Many are the tiniest of their kind and found nowhere else on Earth.
岛屿上的食物与生存空间十分有限
Food and space is so limited on islands.
这里大多是“小者生存”
It's often survival of the smallest.
但是天堂也有阴暗面
But paradise has a darker side.
当飓风季节到来
When hurricane season hits,
小型动物必须面对地球上最强大的力量
tiny animals must face some of the greatest forces on the planet.
《加勒比海岛》
在晴朗的日子里 加勒比海岛 充满了各种可能
On sunny days, life on a Caribbean island is buzzing with possibilities.
这是一只雄吸蜜蜂鸟
A male bee hummingbird.
它正在寻找配偶
Looking for a mate...
靓丽的羽毛就是为了吸引异性
and dressed to impress.
但是这只雌鸟很忙
But this female's busy.
它在照顾两只小鸟
She's caring for two chicks,
小鸟刚从咖啡豆大小的蛋里孵化出来
just hatched from eggs the size of coffee beans.
它们的家和咖啡杯一样大
Into a home the size of an espresso cup.
它们以昆虫和花蜜为食 四天后体型就能长大一倍
In four days, they'll double in size on a diet of insects and nectar.
为小鸟提供这些食物是一项艰巨的任务
Providing all this food is a mammoth task.
蜂鸟的能量消耗速度 大于其他任何一种动物
Hummingbirds burn energy faster than any other animal.
所以鸟妈妈必须每天从几百朵花中采集
So she must visit hundreds of flowers a day.
它的体型太小了 昆虫是它的主要竞争对手
She's so tiny, bugs are major competition.
在鸟妈妈觅食的同时 鸟巢失去了保护
And while she feeds, the nest is unprotected.
即使是一只蚂蚁都会对它造成威胁
Even a single ant is a threat.
随着更多蚂蚁蜂拥而至 小鸟陷入了非常危险的境地
And as more swarm in, the chicks are in serious danger.
真及时
Just in time.
鸟妈妈赶了回来 救下了小鸟
She's back to save the day.
长♥期♥以来 加勒比海地区的生物进行了演化
Over time, Caribbean creatures have evolved,
它们体型逐渐变小 以充分利用稀缺的食物
shrinking down to make the most of what little food they can find.
这是一条细盲蛇
A thread snake,
它细得像一根意大利面
as thin as a strand of spaghetti...
长度是其一半
and half as long.
它捕食蚂蚁
He's an ant hunter...
但并非所向无敌
of sorts.
成年蚂蚁太大了 它的小嘴无法将其吞下

但是蚂蚁的幼虫则很容易吞食
But their larvae go down nicely.
每一座岛都有诸如此类 独一无二的小奇迹在上演着
Many of these miniature marvels are unique to a single island.
它只有半根火柴那么长
Just half the length of a matchstick,
侏儒壁虎是世界上最小的蜥蜴之一
the dwarf gecko is one of the smallest lizards in the world.
这种体型非常适合在落叶中捕食微型昆虫
The perfect size to hunt micro-bugs down here in the leaf litter.
但在面对热带暴风雨时 它的尺寸可能太小了一些
But perhaps a little on the small side when up against a tropical storm.
雨点像炸♥弹♥一样落下
Raindrops hit like bombs.
蜂鸟妈妈竭尽全力保护它的宝宝们
The mother hummingbird does all she can to shelter her chicks.
其他鸟儿则飞去躲雨
Others fly for cover.
但是暴风雨太过猛烈
But the storm is so overwhelming...
鸟妈妈除了放弃鸟巢别无选择
there's no choice but to abandon her nest.
在丛林的地面上 雨水汇成了小溪
On the forest floor, the runoff becomes a tidal wave.
但是体型小是侏儒壁虎的一项超能力
But size is a dwarf gecko's superpower.
它太小、太轻了 所以能在水面上行走
So small, so light, he literally walks on water.
可以一直漂浮着直到大水退去
And stays afloat until the flood recedes.
加勒比海地区 每年要经历超过15次热带暴风雨
With over 15 tropical storms battering the Caribbean each year,
天堂会瞬间变成地狱
paradise can quickly turn into hell.
蜂鸟的宝宝们被冲走了
The hummingbird's chicks have been swept away.
它必须从头开始
She must start all over again...
还要赶在下一场暴风雨之前
before the next storm hits.
暴风雨过后 植物被冲到了海里
In the wake of a storm, vegetation is washed out to sea.
小生物和植物一起漂在海上
And with it, creatures are cast adrift.
漂流者们偶尔会幸运地来到新的海滩

很多动物就是这样移♥民♥到新岛上的
This is how many animals colonize new islands.
小而坚强的安乐蜥成功偷渡
Small and hardy, Anolis lizards make successful stowaways.
但是在它之前 早就有其他动物抵达这里了
But others arrived here long before her.
硬毛鼠和美洲鬣蜥靠吃冲上岸的残骸为生
Hutias and iguanas survive by scavenging on whatever washes up.
它必须离开海滩
She needs to get off the beach.
它与安全地带之间只有几米的距离
Just a few meters between her and safety.
几只勇敢的先锋 便可以繁衍出一批新的蜥蜴
It only takes a few brave pioneers to start a whole new population.
暴风雨给大小各异的海滩常客 送上了一份大餐
The storm has delivered a bounty for beachcombers of all sizes...
从硬毛鼠到沙跳虾谁都有份
from hutia to sand hoppers.
但并非每一只小动物都在觅食
But not everyone's on the hunt for food.
这只寄居蟹在找新家
This hermit crab is looking for a new home.
它自己的家已经年久失修
Hers is in serious disrepair.
一批新的海螺壳在暴风雨中被冲上了沙滩
A new supply of shells has washed up in the storm.
但是想找一个合适的并不容易
But finding the right fit isn't easy.
它现在只有高尔夫球那么大
She's only the size of a golf ball.
但寄居蟹可以长到椰子大小
But hermit crabs can grow as big as a coconut
它必须不断更换更大的海螺壳 来适应身体的成长
and must keep upgrading their shells to match.
因为寄居蟹永远需要更大的房♥子
With a never-ending demand for bigger homes,
它们想出了一个绝妙的解决方案
hermit crabs have come up with an ingenious solution.
当一只寄居蟹 找到一个尺寸不合适的海螺壳时
When a crab finds a shell that doesn't fit...
它会发出信♥号♥♥ 让其他寄居蟹来“看♥房♥♥”
it signals to others to come and inspect.
当大小合适的寄居蟹抵达现场
And when the right-sized hermit arrives...
它们便形成一个换房♥链
they form a housing chain.
由大到小排列
Big to small.
最大的先换
The largest moves first.
然后每一只蟹会换进 刚刚腾空的、大一号♥的新家里去
Then each takes the newly vacated property one size up.
这一只寄居蟹来晚了
She's late to the party.
但总是会剩下一个海螺壳
But there's always one shell left over.
即最小的那个
The smallest.
不知用了什么方法 寄居蟹就是知道 自己找到了合适的家
Somehow, a crab just knows when it's found the right home.
终于有像样的避风港了
Finally, a proper shelter.
这正是它需要的
She'll need it.
每年的这个时节 坏天气说来就来
This time of year, bad weather is never far away.
在深入岛内的地方 因为上一场暴风雨 河水依然十分汹涌
Further inland, rivers are still raging from the last storm...
向大海输送着雨水
carrying rainwater out to sea.
但有些生物却逆流而上
But some are heading the other way.
瓢鰕虎鱼会到上游去寻找 最适合繁衍的地方
Tri-tri gobies travel upstream to find the best place to breed.
为了避免竞争 有些雄性会格外努力

这条鱼的尺寸比茶勺还小
He's smaller than a teaspoon,
但是它把鱼鳍当成吸盘 用嘴攀爬
but using his fins as suction cups and his mouth to grip,
便能够战胜急流
he can conquer rapids.
然而这个瀑布
This, however...
可能是个更大的挑战
could be more challenging.
瓢鰕虎鱼可以爬上350米高的瀑布
Gobies can scale waterfalls 350 meters high.
这几乎就好比人类爬上帝国大厦
Almost as high as the Empire State Building.
攀升的过程会持续好几天
The ascent will take days.
有很多鱼会来尝试攀爬
Many attempt the climb...
但是能够活下来的不到1%
but less than 1 in 100 survive.
稳扎稳打就会得到回报
It pays to take it steady.
大功告成
Success.
它获得了繁衍的机会
And a chance to breed.
新一代的小鱼出生后会顺流而下

暴风雨季节的湿气 引发了生物爆发式的繁衍
The humidity of storm season triggers an explosion of life.
牙买♥♥加山地蟹只有方糖大小

它无需浸入水中便可存活
It doesn't need to be in water to survive.
但蟹妈妈还是需要水来繁衍后代
But a mother still needs it to breed.
有些雨水在岩石上形成了小小的积水池
There's rainwater trapped in tiny rock pools,
但是在这里养育子女太危险了
but it's too risky to raise a family out here.
蟹妈妈有完美的解决方案
