Narrator: Why is
this lone dolphin
2
00:00:04,839 --> 00:00:07,373
Making weird patterns
in the mud?
3
00:00:07,375 --> 00:00:11,143
That probably isn't just random.
4
00:00:11,145 --> 00:00:14,013
Narrator: How come a porcupine
is walking right on top
5
00:00:14,015 --> 00:00:17,649
Of this deadly predator?
6
00:00:17,651 --> 00:00:21,153
This is one seriously
sneaky snake.
7
00:00:21,155 --> 00:00:24,323
Narrator: And what on earth are
these two lynx shouting about?
8

[ lynxes shouting ]
9
00:00:31,298 --> 00:00:34,033
Nature is awe-inspiring,
10
00:00:34,035 --> 00:00:36,702
But sometimes,
it just doesn't make sense.
11
00:00:36,704 --> 00:00:39,104
Man: I have never seen
anything like this.

21
00:01:02,263 --> 00:01:04,963
Outdoor enthusiast
michael mccarthy is watching
22
00:01:04,965 --> 00:01:09,168
A lone dolphin
from his see-through canoe.
23
00:01:09,170 --> 00:01:12,404
Then it starts doing
something strange,
24
00:01:12,406 --> 00:01:14,273
So michael launches his drone
25
00:01:14,275 --> 00:01:17,709
To capture a bird's-eye view
of what's going on.
26
00:01:17,711 --> 00:01:20,345
It reveals something
interesting.
27
00:01:20,347 --> 00:01:23,982
As it goes, it's creating this
sort of cloud of muddiness
28
00:01:23,984 --> 00:01:26,318
That is in a big circle.
29
00:01:26,320 --> 00:01:30,422
Narrator: The question is,
what is this lone dolphin doing?
30
00:01:30,424 --> 00:01:32,157
Riskin: Anytime you see
a weird behavior,
31
00:01:32,159 --> 00:01:34,993
There's a very good chance
that it's just play.
32
00:01:39,166 --> 00:01:41,600
We know that dolphins play
a lot of the time,
33
00:01:41,602 --> 00:01:44,103
Both in groups
and by themselves.
34
00:01:44,105 --> 00:01:45,237
Aryee: Sometimes
you see dolphins
35
00:01:45,239 --> 00:01:47,372
Picking up bits of seaweed
36
00:01:47,374 --> 00:01:51,176
And just passing it around
from one dolphin to another.
37
00:01:51,178 --> 00:01:54,446
Daly: Play behavior could be
anything from bow riding,
38
00:01:54,448 --> 00:01:56,548
Leaping out of the water,
39
00:01:56,550 --> 00:01:59,618
And even playing with the sand.
40
00:01:59,620 --> 00:02:01,320
Narrator: Could this dolphin
be messing around
41
00:02:01,322 --> 00:02:04,256
In the mud just for fun?
42
00:02:04,258 --> 00:02:06,625
Where dolphins have been seen
playing in the mud before,
43
00:02:06,627 --> 00:02:09,328
They've been using
their nose in the mud.
44
00:02:09,330 --> 00:02:11,396
Narrator: They use sonar to scan
the bottom
45
00:02:11,398 --> 00:02:13,398
And locate hidden objects,
46
00:02:15,536 --> 00:02:18,237
But this dolphin appears
to be using its tail
47
00:02:18,239 --> 00:02:21,306
As the mud trail
appears behind it.
48
00:02:21,308 --> 00:02:24,576
It doesn't look like the classic
play behavior
49
00:02:24,578 --> 00:02:26,545
That we see in dolphins.
50
00:02:26,547 --> 00:02:29,014
Narrator: Okay, so not play.
51
00:02:29,016 --> 00:02:30,616
What other reason
could the dolphin
52
00:02:30,618 --> 00:02:33,986
Have for dragging
its tail in the mud?
53
00:02:33,988 --> 00:02:35,420
Riskin: There are lots
of marine mammals
54
00:02:35,422 --> 00:02:39,291
That will clean themselves off
by rubbing along the bottom.
55
00:02:39,293 --> 00:02:40,926
Bowhead whales do this.
56
00:02:40,928 --> 00:02:44,530
Killer whales do this.
57
00:02:44,532 --> 00:02:48,467
It's thought to help remove
parasites and shed their skin.
58
00:02:48,469 --> 00:02:52,905
Narrator: But some whales have
more extreme beauty regimens.
59

August 2018,
monterey bay, california --
60
00:02:57,344 --> 00:03:01,146
This lady got
quite a fright.
61
00:03:01,148 --> 00:03:04,383
Woman: [ screams ] oh, my god.
62
00:03:04,385 --> 00:03:07,019
Come on. Get up.
Get up.
63
00:03:07,021 --> 00:03:08,921
That's it.
We need to leave.
64
00:03:08,923 --> 00:03:11,423
Narrator: A humpback whale was
scraping itself clean
65
00:03:11,425 --> 00:03:13,158
On the side
of her boat.
66
00:03:13,160 --> 00:03:16,828
Woman: This is, like, barnacles,
like, whale barnacles.
67
00:03:18,299 --> 00:03:20,399
Narrator: Barnacles
are small crustaceans
68
00:03:20,401 --> 00:03:25,337
That will attach to pretty
much anything, including whales.
69
00:03:25,339 --> 00:03:28,473
These plankton-eating
freeloaders can cause friction
70
00:03:28,475 --> 00:03:30,909
And slow the whales down.
71
00:03:30,911 --> 00:03:33,378
They're probably
a bit itchy, too,
72
00:03:33,380 --> 00:03:37,349
Which is perhaps why this whale
wanted to be rid of them.
73
00:03:37,351 --> 00:03:42,187
Woman: [ screams ] oh, my god.
74
00:03:42,189 --> 00:03:44,389
Narrator: Dolphins don't usually
have barnacles
75
00:03:44,391 --> 00:03:46,458
Because of
their speedy lifestyle,
76
00:03:46,460 --> 00:03:48,827
But they still need
to keep clean.
77
00:03:48,829 --> 00:03:52,130
Dolphins have very flaky
and loose skin.
78
00:03:52,132 --> 00:03:54,233
So it is a possibility
that this dolphin
79
00:03:54,235 --> 00:03:55,601
Is trying to use
the sediment
80
00:03:55,603 --> 00:03:59,171
At the bottom of the water
to clean its body.
81
00:03:59,173 --> 00:04:00,305
Narrator: Sounds good,
82
00:04:00,307 --> 00:04:02,608
But there's a problem
with this theory.
83
00:04:02,610 --> 00:04:04,376
Uh...
84
00:04:04,378 --> 00:04:05,777
What is the problem?
85
00:04:05,779 --> 00:04:07,846
Daly: For dolphins to shed
their flaky skin,
86
00:04:07,848 --> 00:04:09,881
They don't need to rub
themselves up
87
00:04:09,883 --> 00:04:12,751
Against rocks or sand.
88
00:04:12,753 --> 00:04:15,187
Narrator: Instead, dolphins shed
their skin
89
00:04:15,189 --> 00:04:18,257
All the time as they swim.
90
00:04:18,259 --> 00:04:21,260
So cleaning is a dead-end.
91
00:04:23,230 --> 00:04:26,999
Are there any clues
we might have overlooked?
92
00:04:27,001 --> 00:04:28,734
Daly: In this clip, you can see
that the dolphin
93
00:04:28,736 --> 00:04:32,237
Is moving around at the surface
of the water in circles.
94
00:04:32,239 --> 00:04:36,608
And that probably
isn't just random.
95
00:04:36,610 --> 00:04:39,578
Narrator: But why would a
dolphin deliberately stir up mud
96
00:04:39,580 --> 00:04:41,179
In a circle?
97
00:04:41,181 --> 00:04:43,949
The solution to this comes
from paying attention
98
00:04:43,951 --> 00:04:46,752
To what happens
after the circle is drawn,
99
00:04:46,754 --> 00:04:49,721
Because once the mud
is in place,
100
00:04:49,723 --> 00:04:52,824
There are a whole bunch
of fish that react to it.
101
00:04:55,396 --> 00:04:58,797
Humpback whales will go
around in a spiral,
102
00:04:58,799 --> 00:05:01,967
And they'll start releasing
bubbles from their blowholes.
103
00:05:01,969 --> 00:05:05,304
These bubbles basically
make a net, a bubble net,
104
00:05:05,306 --> 00:05:08,473
And it traps the fish inside,
and they gorge on those fish.

00:05:13,614 --> 00:05:15,847
Narrator: It turns out
that bottlenose dolphins
107
00:05:15,849 --> 00:05:18,450
In florida
have created a unique version
108
00:05:18,452 --> 00:05:20,652
Of this technique using mud,
109
00:05:20,654 --> 00:05:22,654
And it's very effective.
110
00:05:22,656 --> 00:05:25,657
The fish in a frenzy
get confused
111
00:05:25,659 --> 00:05:28,660

to leap out of this,
112
00:05:28,662 --> 00:05:32,064
What they see as a solid wall,
this mud ring.
113
00:05:32,066 --> 00:05:34,966
The dolphins then snap up
these fish.
114
00:05:37,638 --> 00:05:39,738
Riskin: What this dolphin is
doing is a hunting technique
115
00:05:39,740 --> 00:05:41,573
Called corralling,
getting a whole bunch of fish
116
00:05:41,575 --> 00:05:45,344
Into a tight cluster
and taking advantage of it.
117
00:05:45,346 --> 00:05:48,847
Aryee: This is the first time
a dolphin has been filmed
118

119
00:05:50,884 --> 00:05:52,818

120
00:05:52,820 --> 00:05:55,020
This behavior
from its counterparts
121
00:05:55,022 --> 00:05:58,690
And has been able
to mud ring by itself.
122
00:05:58,692 --> 00:06:01,126
Narrator: It hasn't snapped up
any fish, though,
123
00:06:01,128 --> 00:06:03,929
So it hasn't
quite nailed the technique.
124
00:06:03,931 --> 00:06:06,598
Despite the great efforts
of this single dolphin,
125
00:06:06,600 --> 00:06:09,468
Obviously,
he's still learning.

Or a beauty regime,

Researchers set up cctv cameras

And it actually steps

And another clip
featuring an animal
140
00:07:07,127 --> 00:07:11,596
That eats puff adders
for breakfast is even weirder.
141
00:07:11,598 --> 00:07:15,400
This cat-like animal, called
a genet, walks right past

This free meal.
143
00:07:18,906 --> 00:07:22,741
So how is the puff adder
going undetected?
144
00:07:22,743 --> 00:07:26,511
Burke: Some animals use a very
simple strategy of camouflage.
145
00:07:26,513 --> 00:07:30,015
They just hide in plain sight.
146
00:07:30,017 --> 00:07:32,317
That's why you have these
beautiful kind of chevron-like
147
00:07:32,319 --> 00:07:35,220
Patterns on the snake.
148
00:07:35,222 --> 00:07:38,256
Narrator: Ash miller at
wits university, south africa,
149
00:07:38,258 --> 00:07:41,626
Has been studying
puff adder behavior.
150
00:07:41,628 --> 00:07:44,996
When they're lying up underneath
a bush or in a grass clump,
151
00:07:44,998 --> 00:07:48,300
You will never see them
unless they're moving,
152
00:07:48,302 --> 00:07:50,302
So when a predator approaches
a puff adder,
153
00:07:50,304 --> 00:07:54,506
It's best form of defense is
actually just to remain hidden.
154
00:07:54,508 --> 00:07:57,075
Narrator: But the puff adder is
the third-most venomous snake
155
00:07:57,077 --> 00:07:59,277
In africa,
after the black mamba
156
00:07:59,279 --> 00:08:01,813
And spitting cobra,
157
00:08:01,815 --> 00:08:05,450
So why put on
the disappearing act?
158
00:08:05,452 --> 00:08:07,219
People often mistake the idea
159
00:08:07,221 --> 00:08:09,020
That a venomous animal
is well-armed.
160
00:08:09,022 --> 00:08:12,023
They're not. The venom is
intended for their prey.
161
00:08:12,025 --> 00:08:14,559
Aryee: Puff adders are ambush
predators,
162
00:08:14,561 --> 00:08:17,162
Which means that they lie
in wait for their prey
163
00:08:17,164 --> 00:08:19,431
To come by
at just the right time
164
00:08:19,433 --> 00:08:23,101
And then, boom,
unleash that venomous bite.
165
00:08:23,103 --> 00:08:26,004
And what that means is the snake
is sitting in one spot
166
00:08:26,006 --> 00:08:28,273
For potentially days
if not weeks at a time,
167
00:08:28,275 --> 00:08:32,677
Which makes it really vulnerable
to predators itself.
168
00:08:32,679 --> 00:08:35,780
Narrator: But camouflage doesn't
always work.
169
00:08:35,782 --> 00:08:38,850
Relying on camouflage is great
if you're trying
170
00:08:38,852 --> 00:08:44,956
To avoid predation by animals
that rely on visual cues,

00:18:19,866 --> 00:18:23,401
Grooming and curling up
with each other,
347
00:18:23,403 --> 00:18:25,903
And this exchange
is pretty intense.
348
00:18:25,905 --> 00:18:29,540
[ lynxes shouting ]
349
00:18:29,542 --> 00:18:31,742
This is not some sort of
sibling rivalry.
350
00:18:31,744 --> 00:18:33,744
This is two random adults
351
00:18:33,746 --> 00:18:37,715
Appearing to be caught
in aggressive conversation.
352
00:18:37,717 --> 00:18:40,952
Narrator: So not a family tiff.
353
00:18:40,954 --> 00:18:42,720
Could this be two male lynx
354
00:18:42,722 --> 00:18:45,323
Having a turf war
over territory?
355
00:18:48,128 --> 00:18:51,095
Cooke: Males occupy
different territories.
356
00:18:51,097 --> 00:18:54,098
So one obvious thinking behind
what's going on here
357
00:18:54,100 --> 00:18:55,199
Is that they've met up.
358
00:18:55,201 --> 00:18:57,135
They both think they own
this bit of land,
359
00:18:57,137 --> 00:18:59,504
And they're having
an argument about it.
360
00:18:59,506 --> 00:19:01,372
Narrator: But the altercation
in this clip
361
00:19:01,374 --> 00:19:04,809
Is all banshee and no bite.
362
00:19:04,811 --> 00:19:08,346
Is this normal for a territorial
dispute between lynx?
363
00:19:08,348 --> 00:19:11,682
If it were two males,
then it would be very likely
364
00:19:11,684 --> 00:19:13,584
That this encounter
would escalate
365
00:19:13,586 --> 00:19:15,586
Into a very aggressive one.
366
00:19:15,588 --> 00:19:17,622
We would have seen
a full-on brawl there.
367
00:19:17,624 --> 00:19:19,490
Narrator:
You mean like these guys?
368
00:19:23,263 --> 00:19:24,362
Okay.
369
00:19:24,364 --> 00:19:26,931
Our video seems a bit tame
after that,
370
00:19:26,933 --> 00:19:30,368
So perhaps not
a territorial dispute.
371
00:19:30,370 --> 00:19:33,404
Then what links these two lynx?
372
00:19:33,406 --> 00:19:36,607
Could it be the oldest story
in the book?
373
00:19:36,609 --> 00:19:38,943
Male and female lynx
are identical.
374
00:19:38,945 --> 00:19:41,312
It's impossible to
tell them apart,
375
00:19:41,314 --> 00:19:45,183
So perhaps we're looking
at a male and a female.
376
00:19:47,353 --> 00:19:50,855
Lynx inhabit areas
with very cold, harsh winters,
377
00:19:50,857 --> 00:19:54,192
So they tend to have
very seasonal breeding patterns.
378
00:19:54,194 --> 00:19:57,962
Narrator: A female will call out
to say she's available,
379
00:19:57,964 --> 00:19:59,697
But males had better be quick
380
00:19:59,699 --> 00:20:03,167
Because she will only mate
once a year.
381
00:20:03,169 --> 00:20:05,269
They tend to mate in the spring.
382
00:20:05,271 --> 00:20:07,772
What we're looking at now
took place in may,
383
00:20:07,774 --> 00:20:09,674
And what looks to me
that's happening
384
00:20:09,676 --> 00:20:12,810
Is this is a male
who's on the prowl to mate.
385
00:20:12,812 --> 00:20:15,379
Unfortunately for him,
he's arrived a bit too late.
386
00:20:15,381 --> 00:20:18,349
Most likely
she's already pregnant.
387
00:20:18,351 --> 00:20:22,153
Narrator: By may, mating season
is well and truly over,
388
00:20:22,155 --> 00:20:25,890
And females are likely
to be off limits.
389
00:20:25,892 --> 00:20:27,525
This is a typical
sort of behavior
390
00:20:27,527 --> 00:20:29,994
Where the male is coming on
to the female,
391
00:20:29,996 --> 00:20:33,197
But she's letting him know
that she's not interested.
392
00:20:33,199 --> 00:20:35,166
Narrator: And it takes
quite a bit of noise
393
00:20:35,168 --> 00:20:37,134
Before he understands.
394
00:20:37,136 --> 00:20:40,104
Schreiber: So effectively, we're
watching a very sad scene here,
395
00:20:40,106 --> 00:20:42,173
A male trying to court a female,
396
00:20:42,175 --> 00:20:44,842
But he's left it way too late,
and she said, "I'm sorry.
397
00:20:44,844 --> 00:20:48,546
I'm uninterested
in your crazy growl advances."
398
00:20:48,548 --> 00:20:50,414
Yeah, tough luck, guy,
next year.
399
00:20:50,416 --> 00:20:56,754
