森林占地球陆地面积的三分之一 Forests cover one third of the lands of the Earth.
全球一半的动物种类隐藏其中 Hiding within them are half of all the animal species on the planet.
但森林是环境复杂的狩猎场 But forests are complex places in which to hunt.
没有清晰的视线 There is never a clean line of sight.
也没有追逐的空间 No room for the chase.
在迷宫般的世界中捕获猎物 To get to its prey in this labyrinthine world
同时避免被发现 without being discovered
森林猎食者必须掌握伏击的技巧 the forest hunter must master the art of the ambush.
老虎是最大的森林掠食者 The tiger is the largest of all forest predators.
然而 其生存依赖于隐藏自己... Yet its life depends on being able to hide itself...
对重达200公斤的猫科动物来说 这并不容易 no simple task for a cat weighing up to 200 kilos.
需要数年才能掌握隐藏技巧 The vanishing act takes years to perfect
从幼崽时期就开始训练 beginning when tigers are just cubs.
和家养的小猫一样 Like domestic kittens, tiger cubs
幼虎无法抑制潜行的冲动 can't resist the compulsion to stalk.
刚开始只是个游戏 At first, it's a game.
但幼虎正在学习技巧 But the cubs are learning the skills
有助于悄无声息行走在嘎吱作响的森林地面 needed to move silently over the crunchy forest floor.
这需要多次练习 It takes practice
还要有毅力 and perseverance.
幼虎会失败多次 A cub will fail many times.
但最终 其生存依赖于日渐成熟的技巧 But, ultimately, its life will depend on getting it right.
当它成为一只年轻的成年虎 By the time it is a young adult,
就能够无声无息地行动 a tiger can move without making a sound.
但为了接近猎物 它必须避免被看到 But to get close to its prey, it must also be out of sight.
鹿群眼目众多 Herds have many eyes,
而且从不放松警惕 and they never let down their guard.
只要它们能看到老虎 就无法被伏击 As long as they can see the tiger, there can be no ambush.
只要能看到 As long as they can see
老虎 the tiger.
还不够近 Not close enough.
为提高捕获鹿的成功率 To stand a good chance of catching a deer,
老虎必须潜行到10米以内 a tiger must stalk to within ten metres
才能发动突袭 before launching an attack.
为了成功 And to do that,
它必须充分利用森林提供的掩护 it must take advantage of any cover its forest provides.
随着经验积累 老虎成为专家 With experience, a tiger becomes expert
能够利用一切机会 at exploiting any opportunity.
风暴的噪音和黑暗有利于隐藏行踪 The noises and darkness of a storm can be used to conceal its approach.
它从下风处靠近鹿群 It moves in downwind of the herd
没有被发现 undetected.
一旦进入攻击距离 它就会静止不动 Once within striking distance, it freezes.
老虎捕猎的终极技巧 The final trick for a hunting tiger
就是等待猎物靠近 is to get closer
而自身纹丝不动 without moving at all.
让这只雄鹿自由靠近 Let the stag come as close as it will.
等待它转身 Then wait for it to turn
然后迈出一步 and take one step away.
完美而英勇的袭击 The perfect strike and brave...
这头雄鹿几乎和老虎一样重 this stag weighs almost as much as the tiger.
它本能地将猎物藏起来 然后享用美餐 It instinctively moves its prize out of sight before starting its meal.
技巧熟练的伏击者 An accomplished ambusher.
需要数年时间训练技巧 Years in the making,
才能将森林的挑战 with the skills to turn the challenges of its forest
转变为自身优势 to its advantage.
并非所有森林都如此 But not all forests are the same.
在遥远的北方 森林随着树木开始延伸 They begin where the trees begin, in the far north.
这是全世界最大的森林 This is the largest forest of all.
不间断的针叶林带环绕地球一周... An unbroken band of coniferous trees that wraps around the globe...
这是亚寒带针叶林 the Boreal forest.
在冬天 看起来空无一物 In winter, it can appear empty
但这无尽的迷宫 是上演独特捉迷藏游戏的竞技场 but this endless maze is the arena for a unique game of hide and seek.
森林中下了数月的雪 Snow falls in this forest for months on end.
当雪逐渐积累在布满枯树枝的 As it collects on the fallen branches and trunks
凌乱森林地面 that litter the forest floor,
在雪下面形成隐藏的迷宫隧道 a hidden labyrinth of snow tunnels is created beneath.
这里与冷空气隔绝 Here, out of the icy air,
是森林中啮齿动物过冬的地方 is where the forest's rodents spend their winter.
看似空旷的森林中也有猎物存在 Prey exists even in this seemingly empty forest
只要你知道去哪里找 if you know where to find it.
这是美洲貂 The American marten.
在冬天 它只住在 It only lives where, in winter,
雪足够深能形成迷宫的地方 the snow is deep enough to create this maze.
细长的体型很适合在雪道中搜寻 Its slim body is ideally shaped for searching snow tunnels,
但这种体型会使热量迅速流失 but that shape means it also loses heat quickly.
它必须持续寻找食物以维持生命 To stay alive, it must continually search for food.
美洲貂嗅到了一股气味 The marten picks up a scent.
它仔细听任何动静 It listens for any movement.
找到了 Found you!
一只老鼠不够吃 One mouse is not enough.
为了在冰冻森林中保持体温 To keep warm in this frozen forest,
美洲貂一天需要捕获3只老鼠 the marten must find three mice every day.
但雪下有数千条隧道 找哪一条呢 But with thousands of tunnels under the snow, which one do you check?
每条都得找 You check them all!
这是疯狂的捉迷藏游戏 A frantic game of hide and seek.
只有十分之一的隧道中有老鼠 Only one in ten tunnels is home to a mouse.
即使如此 也不一定能找到老鼠 And even then, finding the mouse is not guaranteed.
在亚寒带针叶林中的捕猎者 For hunters in the Boreal forest,
仅仅寻找食物就是最大的挑战 just finding food is the biggest challenge of all.
在更南方的森林中 食物更充足 In the forest further south, prey is more abundant.
这是我们都很熟悉的落叶林 The deciduous forest we know so well.
在夏天 一片小鸟的喧闹 In the summer, it's busy with small birds.
树木长有浓密的树叶 The trees are thick with foliage.
这里环境复杂 难以辨认方向 It's a complex world in which to navigate.
这对雌雀鹰来说是个难题 A problem for the female sparrowhawk.
因为它需要产卵 Since she has to produce and lay eggs,
它的体型必须达到一定尺寸 her body must be of a certain size,
在这拥挤的栖息地中 过大的体型不利于偷袭猎物 and she's too big to sneak up on her prey in this crowded habitat.
每年这时候 它依靠另一种... At this time of year, she relies on another...
体型更小更敏捷的捕猎者 a smaller, more agile hunter
它能够快速穿过纵横交错的树林... able to travel at speed through the tangled woodland...
这是雄雀鹰 the male sparrowhawk.
它非常适合在浓密的夏季森林中捕猎 He is well suited to hunting in the dense summer forest
但它必须上缴几乎所有的猎物 but he must give almost everything he catches
给它的老板 to his boss.
雌性有雄性两倍大 She's twice his size!
在夏天 雌鸟和幼鸟都要依靠雄鸟的捕猎技术 In the summer, she and their young depend on his hunting expertise.
雄鸟从不休息 在飞行中对小鸟发动突袭 He never rests, surprising small birds on the wing.
或者藏在高处进行伏击 Ambushing from lofty hiding places.
它是夏季的捕猎专家 He is a specialist summer hunter.
每天 它都提供十只小鸟 Each day, he provides up to ten small birds.
知道游戏规则改变 Until the rules of the game change
秋天来了 with autumn.
落叶树结霜的残叶逐渐脱落 The deciduous trees shed their delicate, frost...prone leaves.
雄鸟这个夏天依赖的掩护 The cover the male relied on all summer
消失不见 is blown.
狩猎从说迷藏变为开阔环境的追逐 The hunt must change from hide and seek to open chase.
雌雀鹰更大的体型成了优势 The greater size of the female sparrowhawk is now an advantage.
它拥有更大的体重和力量以捕获更大的猎物 She has the strength and the weight to catch bigger prey.
雄雀鹰无法扑到体型大的松鸡 Jays are too large for the tiny male to tackle.
这对羽翼刚刚丰满的雌鸟来说 是绝佳的训练对象 But they are the perfect target practice for the fledgling females.
它们无法抗拒挑战 They can't resist the challenge.
看起来像一场游戏 It may look like a bit of fun.
但喳喳叫的松鸡 有助于刚长成的幼鸟进行训练 But buzzing jays helps the fledglings learn
掌握在无树叶为掩护环境中的捕猎技术 how to hunt in a place where there is no leaf cover.
在即将到来的冬天 它们要依靠急停技术 In the coming winter, they will rely on the sudden stall
尾追技术 the tail chase
和拦截技术 the interception
捕获更大的猎物 By taking larger prey,
雌鸟在冬季森林中的生存机会变得更大 the females increase their chances of surviving in the winter forest.
它们一次捕猎就能维持一周时间 Whereas they can last for a week on just one kill,
雄鸟只能捕捉小型猎物 the male, limited to smaller meals,
必须进行两倍次数的捕猎 must hunt almost twice as frequently.
在季节变化如此迅速的森林中捕猎 It's the price the sparrowhawk must pay for hunting in a forest
这是雀鹰必须付出的代价 that changes so radically with the seasons.
有一种森林里 捉迷藏游戏更为复杂 There is a forest where the game of hide and seek is even more complex.
这就是雨林 The rainforest.
植物生长的绝佳环境 A place in which the perfect conditions for plant life
树林繁盛不息 泛滥成灾 never end and the forest runs rampant,
形成最令人眼花缭乱的竞技场 forming the most confusing arena of all.
但一定有猎物藏在某处 But there has to be prey hidden somewhere.
事实上 到处都是 In fact, it's hidden everywhere.
雨林中最大的难题就是大小 The great problem of the rainforest is one of scale.
这里大多数猎物 体型微小 Most of the prey animals here are tiny.
掠食者如何依靠这么小的猎物生存呢 How can a predator hope to survive on such small prey?
答案就是成为小型掠食者 One answer is to be a small predator.
这是波西亚蜘蛛 This is a Portia spider.
波西亚蜘蛛外出捕猎 而不用蛛网 Rather than use a web, Portia ventures out in search of prey.
像这样隐藏起来寻找猎物 Playing hide and seek in this,
这里是最大的迷宫 the mother of all mazes.
它具有三种特殊能力有助于寻找猎物 To help her in her quest, she's equipped with three superpowers.
第一种 惊人的行动方法 First, an amazing approach to getting about.
这是一种会跳跃的蜘蛛 Portia is a jumping spider,
能够跳过体长50倍的距离 able to leap up to 50 times her own body length.
没有地方是它去不了的 Nowhere seems beyond her reach.
第二种特殊能力... 绝佳的视力 Next, her second superpower... superb eyesight.
对于在杂乱环境中分辨猎物必不可少 Essential if she is to distinguish her prey in all this clutter.
因为它的猎物不会四处走动 Because her prey doesn't stray.
波西亚蜘蛛以其它蜘蛛为食 Portia is a spider...eating spider.
这产生了一个难题... This raises a few problems...
其猎物拥有三倍大的体型 her lunch is three times her size
不仅有毒液 packed with venom
而且周围布满陷阱 and surrounded by a sticky trap.
这是不可能的任务吗 Mission impossible?
根本不是 它具有第三种特殊能力 Not at all, because of her third superpower.
波西亚蜘蛛是一个天才 Portia is a genius.
它在三维的世界中行动 She can map her world in three dimensions
并且形成了进攻方案 and formulate a plan of attack.
它有注意了 She can have an idea.
结网的蜘蛛看不到它 The web...builder is blind.
丝毫没有察觉到危险 It won't have a clue that she's coming.
正中目标 Right on target
而且避开了毒牙 and safely behind those fangs.
波西亚蜘蛛利用灵活的头脑 往往可以以智取胜 But a mind as active as Portia's can always do with more brain food.
在这里 没有沿蜘蛛丝滑下去的固定点 Here, there's no anchor point for the abseil.
波西亚蜘蛛有别的方法 But Portia has another idea.
不是去主动找蜘蛛 Instead of going to the spider
它会让蜘蛛来找它 she will bring the spider to her.
它拨动蛛丝来模仿挣扎的猎物 She plucks the strands to imitate struggling prey
吸引蜘蛛 drawing the spider in
自己来送死 to its death.
但波西亚蜘蛛有势均力敌的对手... But Portia does have her equal...
喷网蜘蛛 the spitting spider.
具有竞争力的跟踪者 而且拥有秘密武器 A rival stalker with its own secret weapon.
鼓起的头部武装有喷胶枪 A bloated head armed with glue guns
能喷出黏性蛛丝困住目标 that trap with sticky threads.
只要喷入眼睛 就会让波西亚蜘蛛看不见 One spit in the eye would blind Portia.
但它知道如何避免 But she knows how to avoid that.
只捕捉带着卵囊的雌蛛 Only hunt a female with an egg sac.
在安全的距离尾随 Follow at a safe distance.
跟着它进入巢穴 Track it to its lair.
对波西亚蜘蛛很危险 A dangerous place for Portia.
但喷网蛛被分散了注意力 But the spitter is distracted.
它正在照顾自己的卵 She's tending to her eggs.
波西亚蜘蛛等到恰当的时机 Portia waits for just the right moment.
嘴里有东西无法喷施蛛丝 It can't spit if its mouth is full.
成功了 Mission possible!
对于比波西亚蜘蛛更大的掠食者 For predators larger than Portia,
有一种方法能在短时间内 找到很多小型猎物 there is one way to find lots of small prey in a short space of time.
只要等到夜幕降临 Wait until nightfall.
在黑暗的掩护下 Under cover of darkness,
森林中很多小型动物活跃起来 the forest comes alive with small animals
它们相信黑夜能提供掩护 trusting that night will hide them.
其实不然 It won't.
一些捕猎者在月光下埋伏 Some hunters ambush by moonlight.
这是眼镜猴 The tarsier.
只有人类手掌大小 No bigger than a human hand,
却拥有哺乳动物中相对于体型最大的双眼 with the largest eyes of any mammal relative to body size,
还有像蝙蝠的巨大耳朵能听清 and huge, bat like ears to pick out
一片嘈杂中的刮擦声 a telltale scratch amongst the hubbub.
黑暗无法为昆虫提供隐藏 以躲避眼镜猴 The darkness can't hide an insect from a tarsier
但眼镜猴却能藏于黑暗 来捕捉昆虫 but it can hide a tarsier from an insect.
但眼镜猴之间存在竞争 Because tarsiers compete for food,
它们在捕猎时相互保持距离 they keep their distance while hunting
只搜索自己的丛林领地 each sweeping its own patch of jungle.
但在它们捕猎时 But while they hunt
自己也会成为猎物 they too are hunted.
它们有自己的黑夜跟踪者 They have their own night stalker.
一条网纹蟒蛇 A reticulated python.
它使用能感知气味和热量的器官 在黑暗中寻找猎物 It uses scent and heat sensing organs to find its prey in the dark.
如果眼镜猴发现了蟒蛇 它们有应对方法 If the tarsiers spot it, they know what to do.
召集大部队 Call in the troops!
周围所有的眼镜猴 All the tarsiers in the neighbourhood
放弃捕猎并集合起来 abandon their hunts and rally together
朝着蟒蛇发出高频音尖叫 screaming at the python with high pitched calls.
大势已去 蟒蛇被赶走了 The game is up, and the snake is driven away.
数量多是安全的 There is safety in numbers,
但当骚乱结束后 but when the commotion is over,
每只眼镜猴仍旧各顾各的 it's back to every tarsier for itself.
在白天 另一场捉迷藏游戏在高处展开 By day, a different game of hide and seek takes place high above,
就在丛林的顶层 in the jungle canopy.
这里是更开阔的竞技场 A far more open arena,
悬在30米的高空 hanging 30 metres up in the air,
更大的猎物居住在此 and home to larger prey.
一群群猴子 Troops of monkeys
正在享用大树的花朵和果实 feasting on the flowers and fruits of the giant trees.
因为猴子时常面临坠落的风险 它们需要 Because monkeys are always at risk of falling, they need
前视的双眼 以判断到下一根树枝的距离 forward facing eyes to judge the distance to the next branch
这导致它们有一个盲点 which means they have a blind spot.
这是角雕 拥有长如熊爪的鹰爪 The harpy eagle. With talons as long as a bear's claws,
翼展长达两米 它是空中伏击的高手 and a two metre wingspan, it's the master of the aerial ambush.
如果猴子在树顶之下 If a monkey is under the canopy,
角雕就抓不到 it's out of the harpy's reach.
只有猴子从隐蔽处跳出来 It's only when one breaks cover
才有机会抓到它 that it becomes available.
角雕的捕猎方法是有代价的 The harpy's way of hunting comes at a price.
带着猴子这么重的猎物飞行 肌肉要足够强壮 To fly with prey as heavy as a monkey, it must build enough muscle
这让它成为地球上力量最大的鹰 to become the most powerful eagle on Earth.
因此 养育角雕幼鸟要付出非同一般的辛劳 Raising a harpy chick, therefore, takes an extraordinary commitment.
角雕的育雏期是所有猛禽中最长的 Harpies have the longest period of parental care of any bird of prey.
它们养育幼鸟长达两年 They feed their chick for up to two years.
在此期间 父母会给幼鸟带回200多只猴子和树懒 In that time, the parents will bring it over 200 monkeys and sloths.
在年末 它已经完全长大 At the end of a year, it's fully grown
但离最终独立还很远 but it's far from the finished article.
它必须用数月时间 It must spend many more months
在丛林训练场中锻炼肌肉 building up its flight muscles for the heavy lifting ahead
以便将来能拖起沉重的猎物 by working out at the jungle gym.
更加需要的是 And, more demanding still,
它必须学习在空中伏击猎物的技巧 it must learn the art of the ambush in this aerial world.
不让猴子发现并不容易 Trying to hide from monkeys is not easy.
对幼鸟的第一次捕猎 There are more straightforward options
还有更简单的选择 for the chick's first encounter.
一只三趾树懒... A three toed sloth...
丛林中最缓慢的猎物 the slowest prey in the jungle
完全无法逃脱角雕的捕猎 with no way of escaping an eagle.
原本只是走走样子 It should be a formality
但树懒也会反抗 but even sloths fight back.
这是重要的一课 It's a valuable lesson.
在丛林中捕猎大型动物从不简单 Hunting the jungle's larger animals is never simple.
幼鸟必须赶紧训练技术 The chick must raise its game soon.
毕竟 这里是它父母的领地 After all, this is its parents' territory.
如果它不开始自己捕猎 If it doesn't start hunting for itself,
即便父母辛苦养育 它们也会杀死这只幼鸟 even after all their efforts, they may kill it
给另一只幼鸟让路 to make way for another that will.
大多数森林掠食者单独捕猎 While most forest predators hunt alone,
有些却群体行动 some work as a team.
黑猩猩使用复杂而机智的伏击方法 Chimpanzees hunt monkeys by using the most complex
来捕猎猴子 and intelligent ambush of all.
当它们作出决定 When they decide to do so,
整个队伍踏上寻找猎物的长途跋涉 the whole troop sets out on an extended trek in search of prey.
一旦听到猴子的叫声 所有黑猩猩立刻静音 Once they hear monkey calls, all the chimps switch to silent mode.
它们在下方小心翼翼地移动 Carefully, they move in beneath.
疣猴在30米高处的浓密树顶层 Colobus monkeys, 30 metres up in the dense canopy.
只靠一只黑猩猩 It's almost impossible
在森林里几乎不可能抓到猴子 for a single chimp to catch a monkey in this forest.
疣猴的体重比黑猩猩轻一半 The colobus are less than half their weight,
能借助小树枝逃跑 却无法承受黑猩猩的体重 and can escape using small branches that cannot support a chimp.
黑猩猩必须团队合作 设下陷阱 The chimps must work together to set a trap.
最有技术的捕猎者 The most accomplished hunter
判断出疣猴可能逃跑的路线 judges the possible escape route of the colobus,
然后悄悄地到森林前方 and moves silently ahead in the forest.
它提前进入伏击位置 He takes up an advanced, ambusher position,
隐藏在树顶层之下的树枝间 hidden in the branches just below the canopy.
其它黑猩猩作为包围者 Other chimps, the blockers,
领导群体 爬到疣猴的两侧 take his lead, climbing up either side of the colobus,
使它们看起来明显把其它逃跑路线封锁了 making themselves obvious to close off other escape routes.
最后一只黑猩猩是驱赶者 The last chimp is the driver.
它的任务是将疣猴赶入陷阱 His job will be to chase the colobus into the trap.
当所有黑猩猩就位 它发动进攻 When all are in position, he launches the attack.
当驱赶者保持势头 While the driver keeps up the momentum,
包围者会封住缺口 the blockers move to close any gaps.
猴子朝陷阱逃去 The monkeys flee towards the trap.
当它们到了伏击的那棵树 陷阱就会发动 When they reach the ambush tree, the trap is sprung.
疣猴被带到地上 A colobus is brought to the ground.
每只黑猩猩急不可耐 Everyone is desperate for a share.
但肉有一种独特的分法 But the meat is divided up in a specific way.
捕猎者优先选择 The hunters take the choice cuts.
等级高的雌猩猩和幼猩猩也分到了肉 High ranking females and their offspring get their share.
没有出力的雄猩猩 觉得受到了不公的待遇 Males who played no part in the hunt feel hard done by,
变得沮丧又生气 and become frustrated and sulky.
在群体以植物为主的食谱中 肉食很宝贵 Meat is a precious treat in the troop's largely vegetarian diet.
这在黑猩猩的社会中起了重要作用 But it plays a vital role in chimp society.
通过分享猎物 In sharing their catch,
黑猩猩们加强了纽带 利于群体成功合作 the chimps reinforce the bonds that enable them to succeed as a group.
尽管黑猩猩们的合作十分机智 But for all the chimps' intelligence and teamwork,
它们捕猎的成功率只有一半 their hunts only succeed about half the time.
事实上 只有一种动物 In fact, there's only one animal
完全掌握了在森林中常胜的捕猎技术 that has mastered the forest hunt enough to win every time.
面对它毫无藏身之处 There is nowhere to hide from it.
这是地球上最成功的捉迷藏玩家 It is the most successful player of hide and seek on Earth
蚂蚁大军 the army ant.
看似包含上百万个体的球状物 This may look like a ball of a million individuals,
别犯错误... but make no mistake...
整个群体统一行动 the colony acts as one.
拥有两百万根触角作为传感系统的超级生物体 A super organism with a sensory system of two million antennae.
工蚁的活体形成框架 A skeleton made from the living bodies of workers.
兵蚁形成防御系统 A defence system of soldier ants
随时准备应对危险迹象 ready to act at any sign of danger,
内部的消化系统处理大堆的食物 a digestive system processing piles of food deep inside.
甚至还有专门处理废弃物的系统 Even a coordinated system for dealing with all the waste.
通过合作 这些昆虫超越了个体尺寸 These are insects that, by working together, transcend individual size.
群体会搜索整个丛林 The colony can search the entire jungle
洗劫一切野生动物 and flush out its wildlife.
每天派出一架无声探测器到森林里 Each day, it sends out a silent probe into the forest
寻找食物 in quest of food.
不像其它蚂蚁那样用侦察兵 It doesn't use scouts like other ants.
相反 巨大的搜索队向处女地推进 Instead, a vast search party pushes into virgin territory
寻找任何生命迹象 seeking out the signs of anything alive.
它们伸展开10米宽的前沿 They spread out along a ten metre front,
扫过森林的地表 sweeping across the forest floor.
为找到猎物 蚂蚁们必须接触到 To find prey, the ants must first touch it.
讽刺的是 森林中最成功的捉迷藏玩家 The irony is that this, the most successful hide and seek player
几乎完全看不见 in the forest, is almost completely blind.
它们只依靠动作分辨活物 It distinguishes the living only by their movement.
只要动物保持静止就会很安全 As long as an animal remains still, it is safe.
但就算最轻微的抽动也会暴露自己 But the slightest twitch will give it away.
几秒钟内 猎物就被拖倒 Within seconds, the prey is pinned down.
几分钟以内 关节就会被扯断 Within minutes, it's torn apart at its joints.
猎物越是挣扎 蚂蚁们进攻就越猛烈 The more the prey struggles, the more the ants engage.
进攻前沿的正对面 Right across the raid front,
所有大小的猎物被迫逃出隐蔽所 prey of all sizes are driven from their hiding places.
在蚂蚁们到来时 就连黄蜂也得放弃巢穴 Even wasps must abandon their homes when the ants arrive.
侵入者路线上的所有活物 Everything alive in the path of the raiders
都被绝对数量压倒 overwhelmed by sheer numbers.
这些猎物都是开胃小菜 All this prey is just an appetizer.
蚂蚁大军发现了主要目标... The army has found one of its chief targets...
另一种蚂蚁的群落 a colony of a different kind of ant.
蚁巢位于树顶 The nest is at the top of this tree.
防御黑蚁爬满了树干 The defending black ants swarm down the tree trunk,
在树枝上占好位置 and take up positions on the branches.
但蚂蚁大军派出小股部队 But the army ants send in a legion.
它们紧紧咬住黑蚁 从树上跳下 They lock jaws with the black ants and leap from the tree
使它们退出战斗 to take them out of the battle.
双方阵亡的蚂蚁 如下雨般从树顶落下 Casualties on both sides rain down from the canopy.
蚂蚁大军的目标不是成虫 But the army ants don't want the adults.
它们正在寻找皮肤软嫩多汁的幼虫 They are seeking the soft skinned juicy larvae.
整整一代的白色幼虫被洗劫一空 A whole generation of white grubs is plundered.
蚂蚁大军拖着战利品 The spoils of the ant war are carried along trails
返回主群 leading back to the main colony.
一群灭亡 一群兴盛 Other lines are fresh from other victories.
蚂蚁大军的进攻非比寻常 The army ant raid is an unequalled phenomenon.
超过100万捕猎者 Over a million hunters
捕获几百种猎物 chasing hundreds of species of prey animals.
当这个超级生物体返回巢穴 By the time the super organism returns to its nest each day,
会捕获30000只猎物 30,000 animals will have been caught.
这是地球上最大规模的捕猎行动 It's the largest hunt on Earth,
却由体型最小的捕猎者展开 executed by one of its smallest hunters.
捉迷藏吗 Hide and seek?
游戏结束 Game over.
