1
00:00:03,138 --> 00:00:06,263
The Amazon, the world's mightiest river.

2
00:00:06,501 --> 00:00:10,984
What lives within its hundred meters depths
is one of Earth's greastest mysteries.

3
00:00:12,610 --> 00:00:15,680
Now, an international team of divers and scientists

4
00:00:15,701 --> 00:00:19,087
are seeking life where no human has ever ventured before.

5
00:00:21,083 --> 00:00:23,667
To the very bottom of the Amazon.

6
00:00:24,945 --> 00:00:28,320
The expedition has already found extraordinary creatures,

7
00:00:28,447 --> 00:00:32,709
but they've only begun to explore
what lies within this alien world.

8
00:00:53,671 --> 00:00:57,975
For 3 days, the team have been searching for the giant Jau catfish

9
00:00:58,049 --> 00:01:00,739
but this monster of the deep has eluded them.

10
00:01:00,852 --> 00:01:04,376
The diving is proving far more difficult then they imagined

11
00:01:04,449 --> 00:01:06,264
and they're behind schedule.

12
00:01:06,928 --> 00:01:10,135
A decision is made to split into 2 teams.

13
00:01:10,629 --> 00:01:14,880
In the first, veteran diver and wildlife cameraman Mike DeGruy

14
00:01:14,973 --> 00:01:17,990
joins brazilian professor Mario de Pinna

15
00:01:18,032 --> 00:01:21,271
on a mission to find creatures never filmed before.

16
00:01:21,672 --> 00:01:24,119
Fish that talk, 

17
00:01:24,212 --> 00:01:27,113
animals that hunt using electricity,

18
00:01:28,643 --> 00:01:30,352
but their ultimate goal, 

19
00:01:30,487 --> 00:01:34,686
to discover species completely new to science.

20
00:01:35,086 --> 00:01:38,998
In the second team, Kate Humble head deep into the jungle

21
00:01:39,282 --> 00:01:44,072
Her mission : to track down two of the Amazon's
most elusive animals.

22
00:01:44,360 --> 00:01:46,934
The rare giant otter,

23
00:01:47,651 --> 00:01:52,208
and a strange pink river dolphin, the Boto.

24
00:01:57,391 --> 00:01:59,520
On their quest for new species, 

25
00:01:59,594 --> 00:02:04,045
Mike and Mario have to cross
one of the world's great natural spectacles

26
00:02:04,109 --> 00:02:06,756
The meeting of the waters.

27
00:02:07,320 --> 00:02:12,542
Here the black waters of the Rio Negro
joins the milky waters of the river Amazon.

28
00:02:18,740 --> 00:02:23,550
Now, how long will the very, very definite line of demarkation

29
00:02:23,593 --> 00:02:27,389
It takes several kilometers ,
because the two water types are so different,

30
00:02:27,484 --> 00:02:31,956
but they're actualy not mix for quite some time.

31
00:02:35,541 --> 00:02:38,390
There they are, getting close.

32
00:02:38,906 --> 00:02:40,573
Astonishing.

33
00:02:45,115 --> 00:02:49,398
We're now leaving one river, ... entering another.

34
00:02:51,981 --> 00:02:55,726
Leaving the Rio Negro, they enter the silk-laden Amazon.

35
00:02:55,873 --> 00:02:58,279
Rich in minerals swept from the Andes, 

36
00:02:58,384 --> 00:03:01,251
this river contains more types of fresh water fish,

37
00:03:01,483 --> 00:03:03,329
than anywhere else on Earth.

38
00:03:03,572 --> 00:03:06,695
An ideal hunting ground for new species.

39
00:03:13,954 --> 00:03:16,306
Many people make a living from the river, 

40
00:03:16,333 --> 00:03:20,416
but all are weary of the creatures lurking in these murky waters.

41
00:03:20,637 --> 00:03:23,686
Mike is searching for one of the most feared of all,

42
00:03:23,770 --> 00:03:26,239
it's just 5 centimeters long,

43
00:03:26,379 --> 00:03:28,056
the candiru.

44
00:03:28,162 --> 00:03:31,558
The candiru has a nasty reputation, 

45
00:03:31,622 --> 00:03:35,327
a reputation nastier than pretty much any fish

46
00:03:35,379 --> 00:03:37,552
I've ever met in my entire life.

47
00:03:39,633 --> 00:03:43,990
Candiru are vampires, parasites of other fish.

48
00:03:44,064 --> 00:03:47,746
They enter their host's body through their gills,
and gourge on their blood.

49
00:03:48,461 --> 00:03:50,761
But in the turbulent waters of the Amazon, 

50
00:03:50,834 --> 00:03:54,801
they sometimes enter humans,... by mistake.

51
00:03:58,939 --> 00:04:03,634
There was a medical record of the guy
that had the unfortunate experience

52
00:04:03,834 --> 00:04:06,229
of the candiru swiming up his penis.

53
00:04:06,384 --> 00:04:10,137
So now everything I've been taught not to do :
go into the water,

54
00:04:10,475 --> 00:04:14,032
it's a little fish, that has a nasty habit,

55
00:04:15,421 --> 00:04:18,695
of swiming up your urethra.

56
00:04:18,850 --> 00:04:21,072
That's right, that's what we're about to do.

57
00:04:26,521 --> 00:04:30,619
The candiru is more common on this beach,
than anywhere else on the Amazon.

58
00:04:33,295 --> 00:04:35,455
But there's only one way to find them :

59
00:04:35,543 --> 00:04:37,832
you have to get in the water.

60
00:04:40,826 --> 00:04:42,507
I think we'll be safe.

61
00:04:44,078 --> 00:04:46,171
Or at least I hope we'll be.

62
00:05:00,053 --> 00:05:01,849
100 kilometers away, 

63
00:05:01,890 --> 00:05:04,435
Kate's team is searching for aquatic giants,

64
00:05:04,501 --> 00:05:07,182
somewhere in the world's biggest reservoirs.

65
00:05:07,916 --> 00:05:10,157
When it was damed in 1987, 

66
00:05:10,211 --> 00:05:13,039
it drown half a million trees, creating a lake

67
00:05:13,086 --> 00:05:15,158
larger than Luxembourg.

68
00:05:17,644 --> 00:05:19,994
It's extraordinay.... it has a 

69
00:05:20,080 --> 00:05:22,740
kinda ghostly beauty about it.

70
00:05:25,779 --> 00:05:27,730
This area, now, 

71
00:05:27,749 --> 00:05:29,903
partly because it's so protected, 

72
00:05:30,051 --> 00:05:33,434
has become home not just for a huge diverse

73
00:05:33,473 --> 00:05:36,415
population of fish, including the black piranha,

74
00:05:36,753 --> 00:05:39,318
wich is the most fearsome of them all,

75
00:05:39,986 --> 00:05:42,045
but also to turles, 

76
00:05:42,173 --> 00:05:45,023
and to giant otters.

77
00:05:45,120 --> 00:05:46,788
Very, very exciting.

78
00:05:47,024 --> 00:05:49,792
If Kate and her team can film the giant otters, 

79
00:05:49,811 --> 00:05:53,599
it will also help local scientists identify family members, 

80
00:05:53,638 --> 00:05:56,088
a useful tool for their protection.

81
00:05:58,579 --> 00:06:01,948
But finding the otters in this vast area won't be easy, 

82
00:06:01,995 --> 00:06:05,175
only 3000 remain in the whole of South America.

83
00:06:07,906 --> 00:06:11,741
After 6 hours of looking , Kate hasn't seen a trace of an otter,

84
00:06:11,820 --> 00:06:16,580
but this remote reservoir has become
home to a huge variety of wildlife.

85
00:06:24,636 --> 00:06:26,742
There's so much to look at.

86
00:06:30,742 --> 00:06:34,644
Mike's team are having no more luck in their search for the candiru.

87
00:06:34,710 --> 00:06:38,025
But they have met a trawl of bizzare little aliens,

88
00:06:38,139 --> 00:06:42,507
whose ancestors came from the ocean, 1000 miles away.

89
00:06:43,918 --> 00:06:45,606
Look at those teeth...

90
00:06:45,916 --> 00:06:47,753
The needle-fish.

91
00:06:48,130 --> 00:06:51,728
Have a marine version of this, and looks exacly like this actually.

92
00:06:52,706 --> 00:06:54,684
Snappy little fellow, too.

93
00:06:57,335 --> 00:06:59,928
This...is everybody's favorite...

94
00:07:00,251 --> 00:07:01,763
It's a puffle-fish.

95
00:07:01,965 --> 00:07:03,768
When a predator takes them,

96
00:07:03,923 --> 00:07:06,016
it puffs up, and they can't get them down, 

97
00:07:06,183 --> 00:07:07,453
should have let them go.

98
00:07:07,985 --> 00:07:12,096
Or it can go into a crack or crevice,
and puff up and it can't be extracted.

99
00:07:12,413 --> 00:07:14,978
I need to get them back in the water pretty quicly, tho.

100
00:07:15,977 --> 00:07:18,158
No sign of candiru, yet, 

101
00:07:18,208 --> 00:07:21,435
but , instead, a fish that wards off predators

102
00:07:23,007 --> 00:07:24,506
by talking.

103
00:07:26,888 --> 00:07:29,123
Armored catfish.

104
00:07:33,885 --> 00:07:36,653
Mix these songs, trying to get rid of you.

105
00:07:37,057 --> 00:07:39,621
Go ahead, bring it up, here we go.

106
00:07:39,689 --> 00:07:41,944
Come on, say hi.

107
00:07:44,280 --> 00:07:46,177
He's saying : please let me go.

108
00:07:49,306 --> 00:07:50,609
See ya.

109
00:07:57,458 --> 00:08:01,495
Kate's found another distraction, on her search for giant otters.

110
00:08:01,669 --> 00:08:05,409
A skimmer, plucking fish from the surface of the water.

111
00:08:05,747 --> 00:08:07,361
I suppose this is the ... 

112
00:08:08,331 --> 00:08:11,532
beauty of being in a ...

113
00:08:11,642 --> 00:08:13,478
closed reserve

114
00:08:13,708 --> 00:08:18,063
The animals had absolutely no human contact, so they're not scared of it.

115
00:08:25,991 --> 00:08:28,104
I want to go into the water.

116
00:08:28,347 --> 00:08:31,196
We are absolutely surronded by botos.

117
00:08:31,727 --> 00:08:35,231
Boto, a pink, fresh water dolphin.

118
00:08:35,643 --> 00:08:37,655
Well, the 6 hour journey 

119
00:08:38,214 --> 00:08:41,671
is now extended to...

120
00:08:42,755 --> 00:08:44,713
I think about 8 hours.

121
00:08:45,544 --> 00:08:47,407
It's entirely my fault.

122
00:08:48,283 --> 00:08:50,484
There's so much to look at.

123
00:08:54,338 --> 00:08:57,186
We have to make camp before it gets dark.

124
00:08:58,489 --> 00:09:00,460
We're here for 2 days, I'm sorry.

125
00:09:09,326 --> 00:09:12,796
Mike and his team have been in the water 2 hours.

126
00:09:16,842 --> 00:09:21,413
If a candiru enters their body,
they'll need emergency surgery to cut it out,

127
00:09:27,506 --> 00:09:29,538
but at last, he catches one.

128
00:09:30,301 --> 00:09:32,462
Fortunately, in the net.

129
00:09:34,451 --> 00:09:37,698
These fish have modified teeth outside of the mouth,

130
00:09:38,061 --> 00:09:40,897
so these are not real spines, they are actually teeth.

131
00:09:41,200 --> 00:09:43,293
That what all the fuss is about.

132
00:09:44,382 --> 00:09:47,731
Candiru, the famous and infamous.

133
00:09:47,919 --> 00:09:52,179
Now, when they're full of blood, this will be a little larger in diameter,

134
00:09:52,232 --> 00:09:54,885
and red.
They are about twice the size.

135
00:09:54,904 --> 00:09:59,191
I can feel those spines and ... teeth.

136
00:10:00,027 --> 00:10:02,437
So now we can see how it actually moves,

137
00:10:02,471 --> 00:10:04,726
when it's trying to get in something.

138
00:10:08,647 --> 00:10:10,908
They move on to their ultimate goal:

139
00:10:11,029 --> 00:10:15,012
To discover species completely new to science.

140
00:10:24,641 --> 00:10:27,233
The team are going to try a new tactic.

141
00:10:27,314 --> 00:10:29,272
To dive in the dead of night.

142
00:10:29,315 --> 00:10:32,123
They use the daylight for preparing their gear.

143
00:10:35,206 --> 00:10:39,223
Underwater cameraman Mike Pitts makes his final equipment check.

144
00:10:40,599 --> 00:10:44,765
9 tenths of any job underwater is up here.

145
00:10:45,210 --> 00:10:48,714
Simply you make it up here, 

146
00:10:49,300 --> 00:10:51,164
it's so much easyer when you're down there.

147
00:10:51,555 --> 00:10:54,148
The camera system is ready to go.

148
00:11:00,768 --> 00:11:03,171
It's time to test their theory.

149
00:11:03,872 --> 00:11:06,066
Absorbant time-remaining OK ?
Yeah.

150
00:11:06,924 --> 00:11:09,429
Computer electronics turned on.
Yeah.

151
00:11:10,967 --> 00:11:13,350
Oxygen tank on.
Yeah.

152
00:11:15,401 --> 00:11:18,176
Diving at night is more dangerous.

153
00:11:18,243 --> 00:11:21,032
It's all too easy to get lost in the darkness.

154
00:11:21,162 --> 00:11:23,808
If anything goes wrong, they're totally on their own.

155
00:11:24,173 --> 00:11:26,894
The nearest hospital is 3 days away.

156
00:11:34,521 --> 00:11:38,451
They're all in, I'm getting happier by the minute,
and they're all going for it.

157
00:11:51,315 --> 00:11:54,374
At first, this alien world seems empty.

158
00:12:01,192 --> 00:12:04,223
But an hour into their dive, and 30 meters deep, 

159
00:12:04,311 --> 00:12:07,018
strange creatures start to appear.

160
00:12:13,713 --> 00:12:15,874
The blind tube-snout.

161
00:12:16,015 --> 00:12:19,020
One meter long, but only a centimeter thick, 

162
00:12:19,280 --> 00:12:24,856
it uses its dark pink electric organ to communicate
and find food in the gloom.

163
00:12:28,444 --> 00:12:32,023
But when the fish come out, so did the predators.

164
00:12:40,991 --> 00:12:46,291
Somewhere in the darkness, a Boto dolphin
is searching for prey with sonar.

165
00:12:54,043 --> 00:12:58,162
The Panaque, the only fish on Earth that eats wood.

166
00:13:04,510 --> 00:13:07,467
Their huge gut holds unique bacteria

167
00:13:07,513 --> 00:13:10,322
to digest the dense hardwoods of the Amazon.

168
00:13:25,644 --> 00:13:27,251
Suddenly there's a problem.

169
00:13:29,072 --> 00:13:31,854
Mike Pitts's air supply has malfunctioned.

170
00:13:33,379 --> 00:13:37,896
He's 20 meters below the surface, and in danger of loosing consciousness.

171
00:13:55,308 --> 00:13:58,913
Despite the urgency, it's crucial they ascend slowly.

172
00:13:59,391 --> 00:14:04,576
Coming up too fast can cause serious medical injuries.

173
00:14:34,057 --> 00:14:36,251
The guys were just over an hour into their dive, 

174
00:14:36,312 --> 00:14:38,188
and they had a rebreather problem, 

175
00:14:38,235 --> 00:14:41,023
not entirely sure what it was, 

176
00:14:41,039 --> 00:14:44,791
sounds like some electronics had gone down,
and they had to climb manually.

177
00:14:45,985 --> 00:14:48,314
You're taking first aid precautions.

178
00:14:49,609 --> 00:14:52,040
The last little bit of their ascent

179
00:14:52,295 --> 00:14:57,021
was quit rapid,
and it's the last little bit.... that is important.

180
00:14:57,398 --> 00:15:00,679
We've put them on pure oxygen, as a precaution.

181
00:15:01,799 --> 00:15:05,323
I half considered dropping the camera...half considered it.

182
00:15:06,024 --> 00:15:09,136
And then I thought I can't control it properly.

183
00:15:11,957 --> 00:15:14,381
You feeling alright , fellows ?
Just give me a thumbs up.

184
00:15:19,039 --> 00:15:22,860
The incident drives home just how alone they really are.

185
00:15:32,989 --> 00:15:36,527
Next morning, Kate is been joined by Fernando Costus ,

186
00:15:36,544 --> 00:15:39,764
who's spent 4 years studying giant otters.

187
00:15:40,134 --> 00:15:44,584
He knows, that to have any chance of filming them,
they must start the search at dawn.

188
00:15:47,134 --> 00:15:51,305
It's just gone 5 in the morning...

189
00:15:51,324 --> 00:15:54,558
and Fernando and I are on a quest

190
00:15:54,692 --> 00:15:59,323
to see if the giant otters are having more of a lie in than us.

191
00:16:01,943 --> 00:16:04,961
Fernando often goes days without seeing an otter

192
00:16:05,020 --> 00:16:08,530
and he's developed some unconventional techniques to find them.

193
00:16:23,309 --> 00:16:26,752
This is the den, underneath the vegetation.

194
00:16:27,109 --> 00:16:29,101
The entrance of the den, here.

195
00:16:29,509 --> 00:16:34,141
I'm also collecting some thesis to know
what they're eating here, in the lake.

196
00:16:34,545 --> 00:16:37,630
Because we know giant otters, they eat mainly fish

197
00:16:37,804 --> 00:16:38,979
like piranhas.

198
00:16:39,026 --> 00:16:42,800
And what type of piranhas are in this lake ?
Mainly black.

199
00:16:43,022 --> 00:16:46,127
Big ones...they can reach up to 2 kilos.

200
00:16:46,160 --> 00:16:50,243
They are big animans...
And very agresive.

201
00:16:51,545 --> 00:16:54,131
This lake is teeming with black piranhas.

202
00:16:54,212 --> 00:16:56,440
It should be perfect otter territory,

203
00:16:56,608 --> 00:17:01,239
but as each hour passes, their chance of finding
the otters seems more remote.

204
00:17:09,273 --> 00:17:12,501
Mike and Mario are still on the search for new species.

205
00:17:12,533 --> 00:17:16,307
It's going to take them to places far too shallow for the main boat.

206
00:17:23,283 --> 00:17:25,896
The Amazon's small streams are crystal clear, 

207
00:17:25,970 --> 00:17:28,043
because it hasn't rained for weeks.

208
00:17:28,089 --> 00:17:31,107
This might be their best chance to find new life.

209
00:17:38,281 --> 00:17:40,773
But nothing's that simple in the Amazon.

210
00:17:56,443 --> 00:18:01,230
This rain is gonna wash down the exposed clay and mud,

211
00:18:01,300 --> 00:18:03,210
and it's gonna turn it into muck.

212
00:18:03,285 --> 00:18:06,585
It seems their best hope for finding animals new to science 

213
00:18:06,612 --> 00:18:08,671
is being washed away in the mud.

214
00:18:08,751 --> 00:18:11,774
Finally we find a place where we think we can work, 

215
00:18:11,815 --> 00:18:13,172
and this is what happends.

216
00:18:14,366 --> 00:18:15,993
That's typical, isn't it ?

217
00:18:27,180 --> 00:18:31,319
Back at the reservoir, the sun is shining on Kate and Fernando.

218
00:18:31,540 --> 00:18:35,092
But that means the otters may have left the dens for today.

219
00:18:39,018 --> 00:18:42,461
The opportunity to film them may already have been lost.

220
00:18:51,301 --> 00:18:53,185
They are there, they are leaving the den.

221
00:18:59,448 --> 00:19:00,745
Hello guys.

222
00:19:02,980 --> 00:19:05,026
What was that call ?

223
00:19:05,167 --> 00:19:08,503
A warning call, or is it a sort of...

224
00:19:13,437 --> 00:19:16,989
They are relaxed, they are not alert, they are not in danger...

225
00:19:18,052 --> 00:19:20,834


226
00:19:28,278 --> 00:19:32,666
Hunted for years for their fur,
they were nearly driven to extinction.

227
00:19:33,388 --> 00:19:35,265
Here at least, they are safe.

228
00:19:35,661 --> 00:19:37,768
Creating a unique opportunity

229
00:19:37,795 --> 00:19:41,069
for the biologists to find more about their way of life.

230
00:19:42,405 --> 00:19:43,802
This one's got a fish there.

231
00:19:43,862 --> 00:19:45,388
Big fish.

232
00:19:46,211 --> 00:19:48,055
Just getting a better grip.

233
00:20:29,840 --> 00:20:33,709
Because the feet are totally webbed, they could almost be flippers.

234
00:20:36,510 --> 00:20:39,474
So, do you think this might be the alpha male and female ?

235
00:20:41,552 --> 00:20:45,873
The team's footage will help Fernando to identify family members.

236
00:20:45,933 --> 00:20:49,741
An important step in the protection of these incredible animals.

237
00:20:50,212 --> 00:20:52,163
I can see why...

238
00:20:52,271 --> 00:20:53,675
you came back.

239
00:20:54,390 --> 00:20:58,062
Year after year, after year...

240
00:21:06,138 --> 00:21:08,494
I just don't see this working

241
00:21:09,149 --> 00:21:11,262
Mike's having no luck at all.

242
00:21:11,490 --> 00:21:15,082
The rain has spoiled his chances of finding new species.

243
00:21:15,871 --> 00:21:18,605
This is going to be muddy for the rest of the day.

244
00:21:18,929 --> 00:21:20,158
Hey, Mario !

245
00:21:21,284 --> 00:21:23,856
This just isn't gonna work, I can't see anything.

246
00:21:24,038 --> 00:21:26,934
I think we catch them, put them in the aquarium

247
00:21:29,073 --> 00:21:32,476
Filming animals in ankle-deep mud is impossible.

248
00:21:32,995 --> 00:21:35,439
Mike and biologist Mario decide to catch

249
00:21:35,648 --> 00:21:38,234
and film fish in the tank , instead.

250
00:21:44,348 --> 00:21:47,163
Here, we have several representatives of the...

251
00:21:51,886 --> 00:21:55,505
Is this common here ? on scoop, and you get a dozen fish ?

252
00:21:55,530 --> 00:21:56,881
Yeah, yeah...

253
00:21:57,041 --> 00:22:00,998
A lot of life...
It's amazin how little water can hold so much life...

254
00:22:01,072 --> 00:22:02,341
It's fantastic.

255
00:22:03,756 --> 00:22:07,395
In the net, Mario spots something that looks different.

256
00:22:13,603 --> 00:22:16,243
These people live beside a small stream

257
00:22:16,276 --> 00:22:20,589
that has as many types of fish, as all the rivers in Britain combined.

258
00:22:23,757 --> 00:22:26,579
The team set up a portable jungle studio, 

259
00:22:26,625 --> 00:22:29,204
to film the unusual fish.

260
00:22:51,128 --> 00:22:54,064
At last, they found what they've been looking for.

261
00:22:54,212 --> 00:22:55,900
A new species.

262
00:22:57,680 --> 00:23:00,732
This is perfect...this is ichtiological history.

263
00:23:01,157 --> 00:23:02,434
Just fantastic.

264
00:23:03,776 --> 00:23:05,045
Hold that down

265
00:23:08,108 --> 00:23:11,315
That's no doubt that that's blood.

266
00:23:11,720 --> 00:23:14,522
This is a new species that does really weird,

267
00:23:14,569 --> 00:23:16,804
like sucks blood, in addition to all that,

268
00:23:16,843 --> 00:23:19,483
it has become really small, so it can actually

269
00:23:19,515 --> 00:23:21,703
use the fish in these little creeks.

270
00:23:22,174 --> 00:23:25,536
It's a new species of blood-sucking catfish.

271
00:23:25,685 --> 00:23:29,704
It maybe small, but it's an important scientific discovery.

272
00:23:33,448 --> 00:23:38,052
Animal vampires often posses chemicals
that thin the blood of their victims.

273
00:23:38,485 --> 00:23:42,968
It's possible thier discovery could lead to
better treatments for heart disease.

274
00:23:43,022 --> 00:23:44,130
Well done, Mario.

275
00:23:51,132 --> 00:23:53,319
After Kate's success with the otters, 

276
00:23:53,360 --> 00:23:56,168
she's determined to find the Boto dolphins.

277
00:23:56,788 --> 00:23:58,233
She's had a tip-off

278
00:23:58,583 --> 00:24:01,581
It seems the best place to find wild Boto

279
00:24:01,891 --> 00:24:03,755
is the local beach resort.

280
00:24:21,008 --> 00:24:24,364
This small town has become quite famous for this little restaurant,

281
00:24:25,436 --> 00:24:28,954
because the daugthers of the owners of this restaurant

282
00:24:28,992 --> 00:24:31,308
have been feeding the dolphins

283
00:24:31,414 --> 00:24:35,909
and, maybe, but not only can i feed them,
but I can get into water with them.

284
00:24:45,687 --> 00:24:48,976
Kate lures the Boto, so that the sound recorders

285
00:24:49,023 --> 00:24:52,818
can try and make a rare , underwater recording of their calls.

286
00:25:02,757 --> 00:25:05,241
Even they're coming right up here, 

287
00:25:05,308 --> 00:25:06,361
you still,

288
00:25:07,624 --> 00:25:09,925
can't really get an idea of what look like,

289
00:25:09,959 --> 00:25:12,153
because it's so dark down there.

290
00:25:12,246 --> 00:25:13,839
I want to see your face.

291
00:25:17,134 --> 00:25:18,228
It's one right here.

292
00:25:20,060 --> 00:25:22,491
Unbelivable.

293
00:25:25,224 --> 00:25:28,364
They got long rows of teeth on either side.

294
00:25:29,429 --> 00:25:31,825
Totally twisted beak

295
00:25:33,588 --> 00:25:35,093
Oh, it's a big one here.

296
00:25:35,898 --> 00:25:40,872
Got these really big kind of... bulging... foreheads,

297
00:25:41,805 --> 00:25:43,567
wich is the sonar

298
00:25:43,931 --> 00:25:47,246
wich they definately need in water this dark.

299
00:25:49,910 --> 00:25:52,186
Constant clicking.

300
00:25:53,737 --> 00:25:58,085
Have you noticed that when they come out and take fish,
does the sound change ?...

301
00:26:07,308 --> 00:26:11,804
Now, that Kate attracted the Botos,
the camera team can get in the water.

302
00:26:12,242 --> 00:26:15,463
But they've no idea how these dolphins will react.

303
00:26:31,479 --> 00:26:36,158
The dolphins show no fear of the cameraman,
as they swim through their strange world,

304
00:26:36,204 --> 00:26:39,701
stained deep red from the rainforest's leaves.

305
00:26:47,021 --> 00:26:48,519
It likes you a bit better.

306
00:26:49,675 --> 00:26:51,471
This is fantastic.

307
00:26:58,308 --> 00:27:00,590
Kate's team are achieving their goal,

308
00:27:00,629 --> 00:27:05,429
by capturing remarkable underwater images of these amazing animals.

309
00:27:06,834 --> 00:27:11,465
They're also discovering that wild Botos can be surprisingly gentil.

310
00:27:13,714 --> 00:27:17,711
There this... there are various stories...

311
00:27:17,798 --> 00:27:20,849
legends about Boto that they take human form,

312
00:27:21,241 --> 00:27:23,860
and they whisk away the prettiest girls in the village

313
00:27:24,534 --> 00:27:26,053
and it's very strange, 

314
00:27:26,329 --> 00:27:30,406
looking at them under water, they do look curiously human,
as their skin is

315
00:27:30,801 --> 00:27:32,914
same color as ours, and...

316
00:27:33,811 --> 00:27:38,908
yeah, they have this sort of... 
quite human looking form underwater.

317
00:27:57,548 --> 00:27:59,587
Well, I think

318
00:27:59,938 --> 00:28:02,565
they are officialy full.

319
00:28:03,158 --> 00:28:05,879
This one, just down here, tickling my feet....

320
00:28:07,639 --> 00:28:10,387
That's it...no more fish

321
00:28:10,688 --> 00:28:14,637
What an amazing , ... amazing experience.

322
00:28:21,181 --> 00:28:24,260
Tomorrow the expedition heads further upriver,

323
00:28:24,286 --> 00:28:28,114
and has a close encounter with a giant anaconda.
