00:12:37,733 --> 00:12:42,000  
自然界既有光明  
In nature, there is dark, as well as light...  

133  
00:12:42,000 --> 00:12:44,266  
也有晦暗的中间地带。  
and all shades in between.  

134  
00:12:50,966 --> 00:12:54,500  
在充满利益竞争、  
In communities full of competing interests,  

135  
00:12:54,500 --> 00:12:56,800  
饥饿与背叛的生态圈里  
hunger, and betrayal,  

136  
00:12:56,800 --> 00:13:01,200  
清洁虾为何要接近危险的海鳗？  
why would a shrimp go near a dangerous moray eel?  

137  
00:13:15,600 --> 00:13:18,533  
这是清洁虾。  
It's a cleaner shrimp.  

138  
00:13:18,533 --> 00:13:22,100  
海鳗屏住呼吸。  
The moray holds its breath.  

139  
00:13:22,100 --> 00:13:25,866  
清洁虾毕生为其他生物服务  
Cleaner shrimps dedicate their lives to others,  

140  
00:13:25,866 --> 00:13:28,766  
它们与海鳗之间  
and an extraordinary trust has built up  

141  
00:13:28,766 --> 00:13:31,433  
建立了非凡的信任关系。  
between them and the moray eels.  

142  
00:13:33,233 --> 00:13:37,400  
随处可见生物们并非互相捕食  
Everywhere you look, animals are not eating each other,  

143  
00:13:37,400 --> 00:13:40,833  
而是互相清洁的场景。  
but cleaning each other.  

144  
00:13:40,833 --> 00:13:44,633  
鱼类会专程前往特定清洁站  
Fish travel to a particular cleaning station  

145  
00:13:44,633 --> 00:13:46,666  
常通过变色发出信号  
and often change color as a signal  

146  
00:13:46,666 --> 00:13:49,100  
示意需要清洁服务。  
that they're hoping to be cleaned.  

147  
00:13:50,900 --> 00:13:54,166  
它们光顾的频率远超实际需求。  
They come far more often than they need to.  

148  
00:13:54,166 --> 00:13:56,766  
这种互动存在某种吸引力  
There's something about it that they like  

149  
00:13:56,766 --> 00:13:58,700  
让它们乐此不疲。  
and keeps them coming back.  

150  
00:14:01,233 --> 00:14:03,033  
专业清洁站  
Specialist cleaning stations  

151  
00:14:03,033 --> 00:14:06,166  
遍布太平洋各处的礁岩带。

152  
00:14:11,400 --> 00:14:14,500  
在夏威夷海域 绿海龟定期造访  
Around Hawaii, green turtles come regularly,  

153  
00:14:14,500 --> 00:14:18,700  
往往跋涉数百英里而来。  
often from hundreds of miles away.

00:14:18,700 --> 00:14:23,066  
刺尾鱼会清除龟壳上的绿色藻毡。  
Surgeonfish remove a green fuzz of algae.  

155  
00:14:23,066 --> 00:14:27,500  
藻毡会减缓海龟游速 因此清洁背壳至关重要。  
The fuzz slows a turtle down, so a clean shell is important.  

156  
00:14:41,566 --> 00:14:46,133  
这处海龟清洁站是特定礁岩区。  
This turtle cleaning station is a very specific outcrop.  

157  
00:14:46,133 --> 00:14:50,233  
五十英尺外的刺尾鱼另有职责  
50 feet from here, surgeonfish have other jobs  

158  
00:14:50,233 --> 00:14:52,133  
对海龟视若无睹。  
and ignore the turtles.  

159  
00:14:57,700 --> 00:15:01,533  
此类服务中心遍布海洋。  
There are service centers like this all over.  

160  
00:15:01,533 --> 00:15:03,733  
这是全球性网络。  
It's a global network.  

161  
00:15:07,866 --> 00:15:11,033  
向东三千英里的墨西哥近海  
3,000 miles to the east, off Mexico,

164  
00:15:23,900 --> 00:15:25,633  
赶赴这次约会。  
between appointments.  

165  
00:15:30,000 --> 00:15:31,833  
伤口得到处理...  
Injuries are tended to...  

166  
00:15:31,833 --> 00:15:34,800  
微小寄生虫与藻类被清除。

167  
00:15:43,766 --> 00:15:46,100  
天使鱼获得食物  
The angelfish gets a meal,  

168  
00:15:46,100 --> 00:15:49,600  
但这无法完全解释这种关系。  
but that can't quite explain the relationship completely.  

169  
00:15:51,400 --> 00:15:55,200  
存在更古老的炼金术 一种原始生化反应  
There's a much older alchemy, an ancient biochemistry  

170  
00:15:55,200 --> 00:15:57,466  
通过协作行为  
that creates a physiological buzz  

171  
00:15:57,466 --> 00:16:00,133  
产生生理愉悦感。  
out of doing things together.  

172  
00:16:00,133 --> 00:16:03,933  
共生现象可追溯至细菌时代。  
Symbiosis can be traced back as far as bacteria.  

173  
00:16:05,666 --> 00:16:09,533  
协作从生命诞生之初就已存在。  
Cooperation was built into life right from the start.  

174  
00:16:09,533 --> 00:16:13,700  
蝠鲼、天使鱼乃至人类 都能感受这种羁绊。  
And mantas, angelfish, and us -- we all feel it.  

175  
00:16:34,866 --> 00:16:37,933  
即便虎鲨也有伙伴。  
Even a tiger shark has companions.  

176  
00:16:52,233 --> 00:16:57,766  
鮣鱼始终伴随鲨鱼与蝠鲼左右。  
Remoras are constant attendants to sharks and manta rays.  

177  
00:16:57,766 --> 00:17:00,166  
但鲨鱼还有其他关系。  
But the sharks have other relationships.  

178  
00:17:03,566 --> 00:17:07,366  
牛鲨、双髻鲨与护士鲨  
A bull shark, a hammerhead, and a nurse shark

181  
00:17:29,233 --> 00:17:31,533  
它的头部如同扫描仪。  
Her head is a scanner.  

182  
00:18:04,633 --> 00:18:07,300  
人类或许视鲨鱼为恐怖存在  
We may think of sharks as frightening,  

183  
00:18:07,300 --> 00:18:12,166  
但多数邻近鱼类显得从容自若。  
but the majority of fish near them seem relaxed.  

184  
00:18:12,166 --> 00:18:15,033  
这里的生态并非简单粗暴。  
Life here is not simple.  

185  
00:18:15,033 --> 00:18:17,666  
笛鲷鱼群与鲨帮共处  
Schools of snapper hang out with the gang,  

186  
00:18:17,666 --> 00:18:22,333  
但保持着敬而远之的距离。  
though they keep a respectful distance.  

187  
00:18:22,333 --> 00:18:26,433  
过去认为鮣鱼依附鲨鱼是为分享食物  
It was thought that remoras rode with sharks to share their food,  

188  
00:18:26,433 --> 00:18:28,600  
但这条柠檬鲨停下动作  
but this lemon shark has stopped  

189  
00:18:28,600 --> 00:18:31,233  
让鮣鱼为它清洁。  
to allow its remoras to clean it.  

190  
00:18:51,933 --> 00:18:55,666  
柠檬鲨巡游于加勒比海域  
Lemon sharks cruise around the Caribbean  

191  
00:18:55,666 --> 00:18:58,466  
可能与墨西哥湾的雄性相遇  
and may meet males from the Gulf of Mexico  

192  
00:18:58,466 --> 00:19:01,866  
以保持基因库健康。  
to keep the gene pool healthy.  

193  
00:19:01,866 --> 00:19:05,000  
它们都是国际旅行家  
They are all international travelers  

194  
00:19:05,000 --> 00:19:08,133  
带着专属的清洁随从。  
with their own entourage of personal groomers.  

195  
00:19:20,133 --> 00:19:23,766  
并非所有吸盘鱼的相处都如此和谐。  
Not all arrangements with suckerfish are as comfortable.  

196  
00:19:27,733 --> 00:19:32,166  
菲律宾这头儒艮有两类伙伴——  
This dugong in the Philippines has two sets of companions --  

197  
00:19:32,166 --> 00:19:36,066  
常见于鲨鱼蝠鲼身上的流线型鮣鱼...  
the streamlined remoras seen on sharks and mantas...  

198  
00:19:36,066 --> 00:19:37,966  
以及条纹黄金鰺。  
and striped golden jacks.  

199  
00:19:42,300 --> 00:19:46,166  
温顺的儒艮在海草场觅食。  
The placid dugong grazes the seagrass meadows.  

200  
00:19:51,700 --> 00:19:54,066  
黄金鰺会捕捉  
The golden jacks grab small shrimps  

201  
00:19:54,066 --> 00:19:56,233  
儒艮搅起的小虾。  
that the dugong stirs up.  

202  
00:20:02,100 --> 00:20:04,766  
它似乎乐得有这些伙伴相伴。  
He seems content to have them around.  

203  
00:20:18,300 --> 00:20:23,233  
而鮣鱼却令它困扰不已。  
The remoras, on the other hand, seem to trouble him.  

204  
00:20:23,233 --> 00:20:25,700  
它们并非有效的清洁工。  
They don't seem to be useful cleaners.  

205  
00:20:25,700 --> 00:20:27,666  
实际上它们只想抢夺  
In fact, they only want to eat  

206  
00:20:27,666 --> 00:20:31,500  
虾虎鱼喂给清洁虾的食物。  
what the shrimp goby feeds his shrimp.  

207  
00:20:31,500 --> 00:20:35,466  
多数鮣鱼与清洁虾一样 都是食粪者。  
Most remoras are poop-eaters, just like the shrimp.  

208  
00:20:37,066 --> 00:20:39,200  
儒艮厌恶这种行为。  
The dugong hates it.  

209  
00:20:39,200 --> 00:20:41,400  
这必定令它非常不适。  
It must be very uncomfortable.  

210  
00:20:58,366 --> 00:21:02,533  
它先尝试摩擦身体驱赶 但无济于事。  
First, he tries to rub them off, but that doesn't work.  

211  
00:21:04,366 --> 00:21:05,866  
启动B计划。  
Plan B.  

212  
00:21:05,866 --> 00:21:09,400  
它翻滚身体掀起泥沙云雾。  
He rolls around, creating a cloud of silt and sand.  

213  
00:21:15,633 --> 00:21:17,700  
试图拍打驱离它们。  
He tries to bat them away.  

214  
00:21:30,200 --> 00:21:32,733  
当浑浊的泥沙幕布形成后  
Once he's got a dense cloud cover going,  

215  
00:21:32,733 --> 00:21:36,400  
它带着黄金鰺悄然离去...  
he sneaks off with his golden jacks...  

216  
00:21:36,400 --> 00:21:38,466  
仅剩一条鮣鱼跟随。  
and only one remora.  

217  
00:21:45,933 --> 00:21:50,933  
自然界常被视为无情的竞争场。  
The wild has often been seen as mindless competition.  

218  
00:21:50,933 --> 00:21:54,266  
动物被看作野蛮未开化  
Animals were violent and unsophisticated,  

219  
00:21:54,266 --> 00:21:57,366  
遵循弱肉强食法则。  
nature red in tooth and claw.  

220  
00:21:57,366 --> 00:21:59,966  
适者才能生存。  
Survival was for the fittest.  

221  
00:22:03,166 --> 00:22:08,666  
人类曾认为海洋冷酷无情 毫无温情。  
We felt that the ocean was heartless, friendless.  

222  
00:22:08,666 --> 00:22:11,533  
恐惧源于无法融入。  
We fear what we are not part of.  

223  
00:22:15,866 --> 00:22:18,266  
美国西海岸的寒冷上升流  
Cold upwellings on America's West Coast  

224  
00:22:18,266 --> 00:22:20,233  
富含浮游生物  
are rich in plankton,  

225  
00:22:20,233 --> 00:22:23,633  
管海葵用带刺触手  
and tube anemones catch the current's tiny passengers  

226  
00:22:23,633 --> 00:22:25,600  
捕捉洋流中的微小过客。  
on stinging tentacles.  

227  
00:22:27,966 --> 00:22:30,333  
但人类从未想过  
But we certainly never thought of them  

228  
00:22:30,333 --> 00:22:33,000  
它们属于更宏大的体系。  
as part of anything bigger.  

229  
00:22:38,766 --> 00:22:43,866  
此处的管海葵高达一英尺  
Tube anemones here are taller than most, up to a foot tall,  

230  
00:22:43,866 --> 00:22:47,800  
或许得益于彩虹海蛞蝓的存在。  
probably because of the rainbow nudibranchs.  

231  
00:22:47,800 --> 00:22:50,900  
海蛞蝓是海生腹足类动物。  
Nudibranchs are sea slugs.  

232  
00:22:50,900 --> 00:22:53,800  
这种名为枝背海蛞蝓  
This one is Dendronotus,  

233  
00:22:53,800 --> 00:22:57,933  
专食管海葵的刺细胞触手。  
and it eats the tube anemone's stinging tentacles.  

234  
00:23:10,566 --> 00:23:12,866  
海葵蜷缩躲避。  
The anemone recoils.  

235  
00:23:12,866 --> 00:23:14,866  
为时已晚。  
Too late.  

236  
00:23:14,866 --> 00:23:16,900  
但细看会发现  
But look closer.  

237  
00:23:16,900 --> 00:23:19,566  
它只取食一两根触手。  
He only takes a tentacle or two.  

238  
00:23:24,533 --> 00:23:26,700  
许多海蛞蝓甚至不会消化  
Many nudibranchs do not even digest  

239  
00:23:26,700 --> 00:23:29,433  
从海葵获取的刺细胞  
the stinging cells from anemones,  

240  
00:23:29,433 --> 00:23:31,600  
而是将其融入皮肤  
but incorporate them into their skin  

241  
00:23:31,600 --> 00:23:34,600  
用于自身防御。  
for their own defense.  

242  
00:23:34,600 --> 00:23:39,833  
它取食有度 以维持食物源持续存活。  
He takes as little as he needs to keep the supply alive.  

243  
00:23:39,833 --> 00:23:42,400  
它更像是农夫而非掠食者。  
He's more farmer than predator.  

244  
00:23:42,400 --> 00:23:44,833  
这种经过数百万年  
It's a partnership that has been finely tuned  

245  
00:23:44,833 --> 00:23:47,400  
精细磨合的共生关系。  
over millions of years.  

246  
00:23:49,533 --> 00:23:53,300  
寒流将我们带往加利福尼亚北部。  
The colder currents take us north along California.  

247  
00:23:57,466 --> 00:23:59,366  
此处的上升流更寒冷  
The upwellings are colder here,  

248  
00:23:59,366 --> 00:24:01,700  
生长着巨型海藻林。  
and there are beds of giant kelp.  

249  
00:24:06,900 --> 00:24:10,100  
若将热带珊瑚礁比作海洋都市  
If the tropical coral reefs are the ocean's cities,  

250  
00:24:10,100 --> 00:24:13,566  
这里便是海底的原始森林。  
then these are the sea's ancient forests.  

251  
00:24:21,133 --> 00:24:24,666  
这是沙丁鱼幼体的育婴所。  
It's a nursery for juvenile sardines.  

252  
00:24:24,666 --> 00:24:29,000  
它们既是独立个体 又如同单一生物般游动  
They're individuals, yet they move like a single organism,  

253  
00:24:29,000 --> 00:24:31,533  
令鸬鹚束手无策。  
to the frustration of the cormorants.  

254  
00:24:37,800 --> 00:24:42,066  
成长中的海狮花费数小时嬉戏玩耍。  
Sea lions, growing up, spend hours just playing together.  

255  
00:24:59,500 --> 00:25:04,200  
独居的七鳃鲨从冰寒深渊浮现  
Solitary sevengill sharks emerge from the freezing depths  

256  
00:25:04,200 --> 00:25:06,800  
如被遗忘的远古巨龙。  
like forgotten dinosaurs.  

257  
00:25:06,800 --> 00:25:10,900  
有些可能已存活数百年 偶尔浮出水面巡游。  
Some may live for centuries and come up to visit sometimes.

月球引力与潮汐影响全球

388  
00:38:27,433 --> 00:38:32,233  
迁徙者准时赴宴

海洋中的巨口掠食者

390  
00:38:34,500 --> 00:38:38,400  
会远道而来赴此盛宴

391  
00:38:48,966 --> 00:38:51,766  
蝠鲼尽力吞食  
The mantas eat what they can,  

392  
00:38:51,766 --> 00:38:54,733  
但盛宴规模远超消化能力

393  
00:39:19,366 --> 00:39:23,533  
来自太平洋寒流带的深海处

随波靠岸时  
They drift inshore, and by the time they arrive,  

398  
00:40:15,200 --> 00:40:18,933  
雌体已怀揣发育中的胚胎囊  
the females are carrying pods of growing embryos.  

399  
00:40:28,033 --> 00:40:30,433  
它们将卵附着于任何固体

400  
00:40:30,433 --> 00:40:33,266  
甚至装饰了伪装蟹

401  
00:40:37,066 --> 00:40:41,733  
产卵完成后 所有成体走向死亡  
Once their eggs have been laid, all the adults die.  

402  
00:40:41,733 --> 00:40:45,466  
它们完成了世代传承的使命  
Their purpose in the chain of generations is fulfilled.

Almost everything will eat the dying parents,  

404  
00:40:57,466 --> 00:40:59,666  
但卵囊例外

405  
00:40:59,666 --> 00:41:01,766  
卵囊含有毒素  
The egg cases carry toxins,  

406  
00:41:01,766 --> 00:41:05,266  
多数捕食者只会尝试一次

407  
00:41:05,266 --> 00:41:08,333  
在每个被精心保护的卵囊内

410  
00:41:23,300 --> 00:41:26,733  
生命爆发将引发连锁反应

411  
00:41:28,300 --> 00:41:31,300  
多数幼体被洋流带走  
The majority of larvae are swept away  

412  
00:41:31,300 --> 00:41:33,666  
成为浮游生物组成部分

413  
00:41:33,666 --> 00:41:36,166  
这颗星球上最大的育婴所

414  
00:41:40,733 --> 00:41:43,833  
海洋亲自哺育它们

415  
00:41:43,833 --> 00:41:46,066  
给予养分与庇护

虹彩栉水母在鱿鱼幼体旁宛若巨兽

水母与螃蟹共同启程

从生命伊始 生物就彼此吸引  
Right from the start, animals are drawn to each other.

427  
00:43:11,533 --> 00:43:13,900  
尽管令人不安

428  
00:43:13,900 --> 00:43:16,933  
我们无法否认

429  
00:43:13,900 --> 00:43:16,933  
在这故事中的角色  
part in this story.  

430  
00:43:53,366 --> 00:43:56,866  
穿越荒芜景象...  
Look beyond the desolation...  

431  
00:43:56,866 --> 00:43:59,533  
与过失

432  
00:43:59,533 --> 00:44:01,100  
为时未晚

这是搬运蟹

海胆获得免费座驾

437

螃蟹从此免受攻击

438  
00:45:27,766 --> 00:45:29,733  
它们结成伙伴

439  
00:45:29,733 --> 00:45:32,100  
公平互利  
It's very equal.  

440  
00:45:32,100 --> 00:45:35,800  
看似不可能的联盟——  
It seems an unlikely relationship --  

441  
00:45:35,800 --> 00:45:38,900  
平凡螃蟹与致命美人——  
a plain crab and a venomous beauty --  

442  
00:45:38,900 --> 00:45:40,966  
但此类共生关系

人类并非只会破坏

447  
00:46:08,866 --> 00:46:13,100  
昔日的毁灭机器如今滋养生命

448  
00:46:24,300 --> 00:46:26,733  
新家园正在建立

449  
00:46:42,866 --> 00:46:45,066  
在沉船与礁岩之间

453  
00:46:57,366 --> 00:47:00,033  
莫过于亲子之情

看 它们的心脏在跳动

家园必须被守护

456  
00:47:17,766 --> 00:47:19,900  
尽管触手带毒

457  
00:47:19,900 --> 00:47:22,866  
玳瑁仍以海葵为食

礁岩上多数海葵守护着育婴所  
Many of the anemones on the reef protect a nursery,  

459  
00:47:26,200 --> 00:47:31,800  
父母必须不惜代价保卫家园  
and the parents must defend their anemone at all costs.  

460  
00:47:31,800 --> 00:47:37,666  
它们知道玳瑁的弱点是眼睛

463  
00:47:43,300 --> 00:47:46,700  
其咬合力足以见血

467  
00:48:14,033 --> 00:48:18,100  
我们如拼图般整合线索

468  
00:48:18,100 --> 00:48:21,366  
逐渐揭示局部真相  
slowly revealing parts of the picture.  

469  
00:48:31,066 --> 00:48:34,166  
人类的善意帮助多是偶然

470  
00:48:36,466 --> 00:48:38,666  
但我们造成的生态废墟

471  
00:48:38,666 --> 00:48:41,800  
最骇人处在于消失的存在  
is most chilling by what's not there.  

472  
00:48:49,633 --> 00:48:55,000  
五百年前鱼类数量或是现今十倍  
500 years ago, there was maybe 10 times as many fish.  

473  
00:48:55,000 --> 00:48:57,866  
难以想象  
It's hard to imagine.  

474  
00:48:57,866 --> 00:49:00,533  
不仅是个体的消亡  
It's not just the individuals lost.  

475  
00:49:00,533 --> 00:49:04,100  
更是它们精妙的共生关系 家族传承  
It's their delicate partnerships, their families,  

476  
00:49:04,100 --> 00:49:08,100  
所有生命联结的断裂  
all the connections between lives, severed.  

477  
00:49:35,866 --> 00:49:39,933  
自然界建立在关系网络之上  
The natural world is built on relationships.  

478  
00:49:39,933 --> 00:49:42,833  
而我们刚刚开始认知  
But what we are only beginning to discover  

479  
00:49:42,833 --> 00:49:46,666  
协作的古老生化机制  
is the ancient biochemistry of cooperation.  

480  
00:49:46,666 --> 00:49:51,033  
单细胞联合形成动植物  
Single cells united to form animals and plants,  

481  
00:49:51,033 --> 00:49:55,433  
它们需要繁衍 创建家园与群落  
and they needed to breed, to create homes and communities,  

482  
00:49:55,433 --> 00:49:58,533  
于是远古神经递质与激素  
and so ancient neurotransmitters and hormones  

483  
00:49:58,533 --> 00:50:02,433  
开始奖励协作行为  
began rewarding collaboration.  

484  
00:50:02,433 --> 00:50:04,933  
这种本能根深蒂固  
The instincts are strong.  

485  
00:50:04,933 --> 00:50:08,233  
成为群体的一部分  
Being together, a part of something,  

486  
00:50:08,233 --> 00:50:10,166  
本就是生命原貌  
just feels right.  

487  
00:50:37,533 --> 00:50:40,466  
动物充满信任  
Animals are very trusting.  

488  
00:51:05,666 --> 00:51:09,900  
渴望融入其中或许看似愚蠢  
It may seem foolish to want to be a part of this.  

489  
00:51:09,900 --> 00:51:12,800  
此处某些生物能轻易杀死人类  
Some here could easily kill us.  

490  
00:51:12,800 --> 00:51:16,666  
它们可能饥饿 而我们恰可食用  
They may be hungry, and we are edible,  

491  
00:51:16,666 --> 00:51:20,266  
但无需恐惧——  
but you don't need to feel afraid --  

492  
00:51:20,266 --> 00:51:23,366  
保持敬畏即可  
just respectful.  

493  
00:51:23,366 --> 00:51:26,800  
听 仔细听  
Listen. Listen.  

494  
00:51:26,800 --> 00:51:29,100  
它们有话要说  
They have something to say.  

495  
00:51:30,833 --> 00:51:32,266  
不妨思考  
Here's a thought.  

496  
00:51:32,266 --> 00:51:35,700  
何不尝试互利共生？  
How about a bit of give-and-take?  

497  
00:51:41,066 --> 00:51:44,966  
我们能体会被信任的感觉  
We can feel what it is like to be trusted,  

498  
00:51:44,966 --> 00:51:48,666  
也能守护所属的生态网络  
and we can help protect what we're part of.  

499  
00:51:59,633 --> 00:52:04,933  
持久屏息最为艰难  
Holding your breath long enough is the hardest part.  

500  
00:52:04,933 --> 00:52:07,633  
但值得坚持  
But it's worth it.  

501  
00:52:09,733 --> 00:52:11,200  
看  
Look.  

502  
00:52:11,200 --> 00:52:15,466  
它们正向我们伸出触手  
They are reaching out to us.
