1
00:00:05,120 --> 00:00:07,240
Our world is not always the same.
2
00:00:09,420 --> 00:00:12,340
Hidden from our view lies a
different world.
3
00:00:14,100 --> 00:00:16,500
Creatures utterly unlike us.
4
00:00:16,620 --> 00:00:18,500
(THUNDER CRASHES)
5
00:00:18,620 --> 00:00:19,900
Almost alien.
6
00:00:21,940 --> 00:00:25,220
Yet they are more numerous
than any other group on the planet.
7
00:00:30,540 --> 00:00:34,900
Welcome to the fascinating
world of the arthropods.
8
00:00:35,220 --> 00:00:39,860
Spiders, scorpions and insects.
9
00:00:40,380 --> 00:00:42,940
Today we have new camera techniques
10
00:00:43,160 --> 00:00:45,880
that will allow us to reveal in
greater detail
11
00:00:46,300 --> 00:00:48,780
than ever before their lives.
12
00:00:49,000 --> 00:00:53,480
The way they fight and feed and
reproduce.
13
00:00:53,600 --> 00:00:57,320
This series uses specially developed
3D camera technology
14
00:00:57,440 --> 00:01:01,080
to study the micro world in
extraordinary detail,
15
00:01:01,400 --> 00:01:04,800
both on location and in specially
constructed environments.
16
00:01:05,940 --> 00:01:08,740
We'll witness their births, the
challenges they face,
17
00:01:09,160 --> 00:01:11,840
and the moments when their lives
hang in the balance.
18
00:01:13,420 --> 00:01:17,220
And that may help us understand
how it is that today
19
00:01:17,440 --> 00:01:22,880
over 80% of all animal species on
this planet are arthropods.
20
00:01:24,320 --> 00:01:27,480
In this series we will see the way
they have evolved.
21
00:01:27,600 --> 00:01:31,240
From the comparative simplicity of
the millipede,
22
00:01:31,360 --> 00:01:34,360
to vast colonies that contain
hundreds, even millions,
23
00:01:34,480 --> 00:01:35,520
of individuals.
24
00:01:38,180 --> 00:01:40,980
We'll witness the most extraordinary
transformations
25
00:01:41,100 --> 00:01:42,620
in the animal kingdom.
26
00:01:43,820 --> 00:01:46,140
We'll meet ants that farm,
27
00:01:46,760 --> 00:01:49,720
spiders that can cast their webs...
28
00:01:51,360 --> 00:01:55,080
..and the bug that wears the bodies
of its victims as a disguise.
29
00:01:57,440 --> 00:02:00,520
Welcome to a strange
and dangerous world.

31
00:02:17,320 --> 00:02:22,640
Our planet's rainforests are home to
millions of animal species.
32
00:02:22,760 --> 00:02:27,560
Nearly 90% of them are arthropods,
some call them bugs,
33
00:02:27,880 --> 00:02:30,440
and they're all searching for food.
34
00:02:30,560 --> 00:02:33,800
In fact, there's food for most of
them everywhere,
35
00:02:34,120 --> 00:02:37,280
because over half
of all bugs eat plants.
36
00:02:54,280 --> 00:02:58,720
Millipedes were among the first
arthropods to move up
37
00:02:59,040 --> 00:03:01,600
out of the water onto the land.
38
00:03:01,820 --> 00:03:04,820
They can have up to 750 legs,
39
00:03:05,240 --> 00:03:09,920
grow to lengths of 30 centimetres
and live for as long as seven years.
40
00:03:10,040 --> 00:03:13,200
And this body plan is so efficient
41
00:03:13,520 --> 00:03:18,480
that it's remained largely unchanged
for hundreds of millions of years.
42
00:03:23,980 --> 00:03:28,140
Their body is divided into segments,
each with its own set of legs
43
00:03:28,260 --> 00:03:30,180
and internal organs.
44
00:03:30,400 --> 00:03:32,720
A heart runs
the entire length of it,
45
00:03:32,840 --> 00:03:34,960
supplying each segment with oxygen.
46
00:03:40,120 --> 00:03:42,760
It eats decaying leaves and plants,
47
00:03:42,880 --> 00:03:46,320
just as its ancestors did
over 400 million years ago.
48
00:03:53,900 --> 00:03:55,940
Millipedes are peaceful creatures,
49
00:03:56,160 --> 00:03:58,640
but they don't have
the forest to themselves.
50
00:04:01,680 --> 00:04:04,400
There are other multi-segmented
creatures here
51
00:04:04,720 --> 00:04:06,800
that have a very different
way of life.
52
00:04:13,920 --> 00:04:15,560
Centipedes.
53
00:04:15,980 --> 00:04:17,780
They are meat eaters.
54
00:04:19,220 --> 00:04:21,980
Centipedes are closely
related to millipedes,
55
00:04:22,100 --> 00:04:23,900
and they prey on other bugs.
56
00:04:25,700 --> 00:04:27,820
There are over 8,000
species of them,
57
00:04:28,240 --> 00:04:30,560
and they all have poisonous stings.
58
00:04:30,880 --> 00:04:33,320
This one lives in caves in India.
59
00:04:34,660 --> 00:04:37,220
Their powerful, independently
moving legs
60
00:04:37,440 --> 00:04:39,960
make them much faster than
millipedes.
61
00:04:48,020 --> 00:04:50,660
This is the one to be feared most -
62
00:04:50,780 --> 00:04:53,131
meet Scolapendra.
63
00:05:10,040 --> 00:05:12,360
But it's not the only top
predator here.
64
00:05:17,060 --> 00:05:19,940
This Red Claw Scorpion from Tanzania
65
00:05:20,060 --> 00:05:22,020
is not as fast or as agile,
66
00:05:22,340 --> 00:05:24,580
but its powerful pincers and sting
67
00:05:24,800 --> 00:05:26,600
make it every bit as deadly.
68
00:05:31,520 --> 00:05:33,920
Scorpions and centipedes are
competitors.
69
00:05:34,040 --> 00:05:35,440
They hunt the same prey...
70
00:05:42,260 --> 00:05:44,260
..and in the same territory.
71
00:05:46,380 --> 00:05:47,740
And because of that,
72
00:05:47,860 --> 00:05:49,540
if they meet, they fight.
73
00:06:19,920 --> 00:06:22,480
Scolapendra uses all its strength
74
00:06:22,600 --> 00:06:25,720
to try and get under
Red Claw's armour.
75
00:06:26,440 --> 00:06:28,720
But the scorpion's defences
are too strong.
76
00:06:41,260 --> 00:06:44,740
It's not Red Claw's attack
that wins the day,
77
00:06:44,960 --> 00:06:47,800
it's Scolapendra's weak
defence that loses it.
78
00:06:50,920 --> 00:06:52,400
If you can't defend yourself,
79
00:06:52,820 --> 00:06:56,740
you're not likely to stay alive
for long in the micro-world.
80
00:07:00,340 --> 00:07:01,380
Australia.
81
00:07:01,500 --> 00:07:04,660
Home to a beetle with one of the
oddest defences.
82
00:07:09,640 --> 00:07:12,160
This is a pie dish beetle.
83
00:07:13,640 --> 00:07:16,320
The outback certainly gets very dry,
84
00:07:16,440 --> 00:07:18,600
so you might think
that this strange shell
85
00:07:18,720 --> 00:07:20,800
is just for collecting water,
86
00:07:21,020 --> 00:07:23,700
but its primary function is defence.
87
00:07:28,620 --> 00:07:29,860
A Mantis.
88
00:07:29,980 --> 00:07:33,300
Normally a hunter,
but with this potential prey,
89
00:07:33,420 --> 00:07:35,540
it doesn't know how to even begin.
90
00:07:56,120 --> 00:07:58,400
But the pie dish beetle's armour
91
00:07:58,520 --> 00:08:01,120
does have its disadvantages -
92
00:08:01,740 --> 00:08:05,020
it's not what you
might call manoeuvrable.
93
00:08:39,140 --> 00:08:43,100
Other Australian insects have a
different defensive strategy.
94
00:08:49,300 --> 00:08:54,460
This stick insect relies on
camouflage to make it invisible,
95
00:08:54,580 --> 00:08:57,100
but that too comes at a cost.
96
00:08:57,520 --> 00:09:01,240
Being shaped like a stick
makes it difficult to fly.
97
00:09:01,460 --> 00:09:05,180
So if a predator does find it,
it could be done for.
98
00:09:34,280 --> 00:09:37,640
A huntsman spider -
and it's ready to strike.
99
00:09:38,840 --> 00:09:42,200
It's one of the fastest
and most agile of all spiders.
100
00:09:49,020 --> 00:09:51,780
But the stick insect
doesn't even try to escape.
101
00:09:54,780 --> 00:09:56,340
She has a weapon of last resort.
102
00:10:03,820 --> 00:10:06,580
A milky substance
from the glands behind her head.
103
00:10:13,120 --> 00:10:15,440
The spray can reach half a metre,
104
00:10:15,560 --> 00:10:19,381
and she'll have enough to have
a few goes before running dry.
105
00:10:24,580 --> 00:10:27,260
It fills the forest with
the scent of peppermint.
106
00:10:30,280 --> 00:10:33,000
To the huntsman,
it's an unbearable irritant.
107
00:10:39,440 --> 00:10:43,466
So the stick insect is free
to graze in peace.
108
00:10:51,020 --> 00:10:53,260
Ever since they first appeared
on land,
109
00:10:53,380 --> 00:10:56,380
the arthropods have been fighting
one and other -
110
00:10:56,600 --> 00:11:00,360
over food, over territory,
over a mate.
111
00:11:00,680 --> 00:11:03,720
The ways they have developed
in order to do so
112
00:11:04,140 --> 00:11:05,780
are truly astonishing.
113
00:11:10,360 --> 00:11:13,280
On the floor of forests almost
anywhere in the world,
114
00:11:13,500 --> 00:11:15,260
you'll find these -
115
00:11:15,480 --> 00:11:16,880
bombardier beetles.
116
00:11:22,680 --> 00:11:24,400
They look fairly harmless,
117
00:11:24,720 --> 00:11:27,720
but not many creatures are foolhardy
enough to try and eat them.
118
00:11:30,800 --> 00:11:32,200
A mantis.
119
00:11:32,320 --> 00:11:34,760
Some mantises are so large
and strong,
120
00:11:35,180 --> 00:11:38,180
they can even kill small birds.
121
00:11:38,700 --> 00:11:40,580
A beetle should be easy.
122
00:11:47,340 --> 00:11:48,340
But not this one.
123
00:11:53,200 --> 00:11:55,600
A fraction of a second after
the mantis strikes,
124
00:11:56,020 --> 00:12:00,180
the beetle squirts hot gas
and caustic chemicals in its face.
125
00:12:06,380 --> 00:12:09,180
The chemicals are produced
by a reaction in its abdomen,
126
00:12:09,600 --> 00:12:13,640
which generates enough heat to bring
the liquid close to boiling point.
127
00:12:21,680 --> 00:12:25,280
The bombardier's spray can be
deadly to smaller creatures...
128
00:12:26,700 --> 00:12:29,580
..but the mantis is large
and it survives.
129
00:12:32,720 --> 00:12:34,167
As does the beetle.
130
00:12:39,200 --> 00:12:40,720
On the African savannah,
131
00:12:41,040 --> 00:12:43,240
there's a hunter that sets its traps
132
00:12:43,460 --> 00:12:45,660
wherever there is dust or dry sand.
133
00:12:51,760 --> 00:12:54,720
This is the lava of an ant-lion.
134
00:12:55,900 --> 00:12:58,980
As an adult, it will look
something like a dragonfly,
135
00:12:59,200 --> 00:13:02,000
and then its sole purpose
will be to mate.
136
00:13:02,120 --> 00:13:03,760
It'll barely even eat.
137
00:13:04,180 --> 00:13:09,060
But now as a larva,
its task is to feed and grow.
138
00:13:09,280 --> 00:13:12,360
To do that, it digs a pit trap
in the sand,
139
00:13:12,480 --> 00:13:16,573
and buries itself at the bottom,
jaws uppermost.
140
00:13:25,820 --> 00:13:27,740
It can jerk its head so violently
141
00:13:27,960 --> 00:13:30,680
that it can shoot up sand grains
like bullets.
142
00:13:35,780 --> 00:13:37,260
And now it waits.
143
00:13:44,100 --> 00:13:46,180
An ant wanders into the pit...
144
00:13:48,740 --> 00:13:50,100
..and loses its foothold.
145
00:14:02,600 --> 00:14:04,480
The ant can't climb out.
146
00:14:04,700 --> 00:14:06,860
The sand slips from under its feet.
147
00:14:13,120 --> 00:14:15,160
Eventually, it tires.
148
00:14:20,520 --> 00:14:23,840
And the ant-lion drags
it beneath the sand...
149
00:14:23,960 --> 00:14:25,080
and devours it.
150
00:14:27,640 --> 00:14:30,840
For the ant-lion, remaining hidden
is a good way to hunt.
151
00:14:40,240 --> 00:14:43,840
And there are a multitude
of places to do that
152
00:14:43,960 --> 00:14:45,040
in a forest.
153
00:14:47,320 --> 00:14:50,160
Here there are predators
that set perhaps the most
154
00:14:50,280 --> 00:14:52,280
perfect of all ambushes.
155
00:14:55,400 --> 00:15:01,020
This female trapdoor spider lives
in a burrow with a camouflaged lid.
156
00:15:05,160 --> 00:15:08,760
And she'll stay here
for her entire 20-year life.
157
00:15:15,960 --> 00:15:17,120
Around the burrow,
158
00:15:17,240 --> 00:15:21,160
she's laid out a network
of invisibly fine strands of silk.
159
00:15:23,420 --> 00:15:25,500
She'll pounce on anything
that trips on them.
160
00:15:26,660 --> 00:15:30,980
Occasionally, she tests to see
that her door opens smoothly.
161
00:15:39,020 --> 00:15:40,820
But mostly, she waits.
162
00:15:43,200 --> 00:15:44,240
A cricket.
163
00:15:48,720 --> 00:15:49,680
Got it.
164
00:16:05,220 --> 00:16:08,380
She pulls her prey into the burrow -
165
00:16:08,500 --> 00:16:11,900
so that she can eat it in safety
and at her leisure.
166
00:16:20,600 --> 00:16:24,040
But some bugs have
such perfect camouflage
167
00:16:24,160 --> 00:16:25,600
they're virtually invisible,
168
00:16:25,720 --> 00:16:27,440
even though they're totally exposed.
169
00:16:34,740 --> 00:16:38,980
Predators use camouflage
to hunt their prey unseen.
170
00:16:39,300 --> 00:16:43,580
Their victims use it to avoid
being found and eaten.
171
00:16:44,100 --> 00:16:47,501
But disguise can be a potent weapon.
172
00:16:53,000 --> 00:16:54,560
In the forests of East Africa,
173
00:16:54,680 --> 00:16:57,080
one insect has taken its camouflage
174
00:16:57,500 --> 00:17:00,500
to a bizarre and somewhat
gruesome extreme.
175
00:17:10,780 --> 00:17:14,260
This is an assassin bug.
176
00:17:14,480 --> 00:17:18,680
To us, it's easy enough to spot
because it moves.
177
00:17:19,000 --> 00:17:21,280
To its prey, that's irrelevant
178
00:17:21,400 --> 00:17:24,703
because it smells
like one of their number.
179
00:17:36,460 --> 00:17:38,980
The assassin sucks its victims dry
180
00:17:39,100 --> 00:17:42,380
and glues their empty
husks onto its back.
181
00:17:42,500 --> 00:17:47,821
This one is already carrying
at least 20 corpses.
182
00:18:05,500 --> 00:18:09,460
Its irregular shape makes it hard
for other predators to spot it...
183
00:18:11,740 --> 00:18:16,060
..and makes it virtually invisible
to its prey - ants.
184
00:18:25,700 --> 00:18:29,020
It enters this ant colony
unchallenged.
185
00:18:32,500 --> 00:18:36,060
Its coat of ant corpses
masks its own odour.
186
00:18:36,180 --> 00:18:39,300
To the ants, it smells
like one of their own,
187
00:18:39,420 --> 00:18:40,780
and that's what matters.
188
00:18:45,260 --> 00:18:47,700
They'll even run straight
over the top of it.
189
00:18:54,040 --> 00:18:58,080
The assassin simply takes an ant
whenever it feels hungry.
190
00:19:03,840 --> 00:19:09,170
And the body of each victim
then adds to its disguise.
191
00:19:17,920 --> 00:19:20,840
Conflict pervades the bug world.
192
00:19:20,960 --> 00:19:22,600
It shapes their bodies.
193
00:19:41,920 --> 00:19:44,200
It dictates their lifestyles.
194
00:19:44,420 --> 00:19:46,420
The ant-lions beneath the sand.
195
00:19:50,540 --> 00:19:54,396
The trapdoor spiders -
20 years in a burrow.
196
00:20:08,140 --> 00:20:10,740
And it's their extraordinary
diversity
197
00:20:10,860 --> 00:20:13,060
that underpins their success.
198
00:20:19,840 --> 00:20:23,360
In the next programme,
I'll look at arthropod predators.
199
00:20:24,820 --> 00:20:28,824
These are the creatures that must
kill in order to eat.
200
00:20:31,900 --> 00:20:35,100
They have evolved the most
extraordinary ways to do so.
201
00:20:37,780 --> 00:20:39,643
And they take many forms.
202
00:20:47,820 --> 00:20:52,580
We'll meet a spider that has
turned its web into a casting net.
203
00:20:55,540 --> 00:20:59,380
We'll witness the ingenious hunting
tactics of another spider
204
00:21:00,000 --> 00:21:01,800
that preys on its fellows.
205
00:21:04,400 --> 00:21:07,480
We'll meet creatures that use
the surface of water
206
00:21:07,600 --> 00:21:10,675
like a radar dish
to detect their prey.
207
00:21:12,400 --> 00:21:16,120
And an extraordinary wasp
that tames a cockroach
208
00:21:16,240 --> 00:21:18,600
so her young can eat it alive.
209
00:21:23,400 --> 00:21:28,115
We'll encounter the most deadly
creatures of the micro-world.
210
