On Mexico's Sea of Cortez a marine |
00:00:08 |
biologist prepares to encounter |
00:00:11 |
local fisherman fear |
00:00:17 |
He is exploring a nether-world |
00:00:21 |
pursuing a legendary monster of |
00:00:33 |
Around the world, |
00:00:36 |
and fishermen catch huge creatures |
00:00:42 |
Bit by bit, the secret life of this |
00:00:47 |
We can study its anatomy and the |
00:00:52 |
the bizarre and wonderful creatures |
00:01:13 |
If they did live anywhere |
00:01:16 |
they would make mince-meat |
00:01:26 |
Fiction has always branded the giant |
00:01:32 |
and some of its close relations |
00:01:51 |
Master of the deep ocean, the |
00:01:55 |
but recently scientists have |
00:02:01 |
"Whales were known to feed |
00:02:04 |
so it made sense to me try to |
00:02:07 |
as our "hound dog" to lead |
00:02:19 |
"We really don't know very much |
00:02:22 |
once they leave the surface. |
00:02:24 |
So we're working with a mystery |
00:02:29 |
Descend with us now |
00:02:30 |
into the dark and mysterious world |
00:02:33 |
and its fearsome quarry, |
00:03:27 |
For most of human history the ocean |
00:03:43 |
Superstitious sailors reported many |
00:03:48 |
Their stories summoned up a fantastic |
00:03:51 |
that threatened them. |
00:03:55 |
These ominous creatures were often |
00:03:59 |
as it frequently did. |
00:04:13 |
Perhaps the most feared of all was |
00:04:17 |
a many-armed beast of incredible |
00:04:21 |
But most sea monsters proved to be |
00:04:26 |
All but "the Kraken" - known |

00:04:56 |
such as octopuses, cuttlefish, |
00:04:59 |
and he welcomes the notoriety |
00:05:04 |
"People have to have their monsters, |
00:05:08 |
and, uh, of course squid make a |
00:05:11 |
because I really think that, um, |
00:05:14 |
especially for many |
00:05:16 |
that the giant squid has become |
00:05:21 |
It's called Architeuthis, |
00:05:28 |
It is the perfect sea monster |
00:05:31 |
and a formidable predator in fact. |
00:05:34 |
It dwarfs most other life in the sea. |
00:05:40 |
It deploys a writhing mass of |

which ensnare its prey and jam it |

It glares upon the world with the |

Clyde Roper has a life-long |
00:06:00 |
and is determined to see one |
00:06:05 |
It all began when he was a teenager, |
00:06:07 |
working as a lobster fisherman |
00:06:11 |
"It doesn't take very long, when |
00:06:14 |
"squids especially, uh, |
00:06:17 |
that giant squids actually exist. |
00:06:20 |
"and, as a idealistic young fellow, |
00:06:22 |
I was pretty, um, |
00:06:25 |
"mis-truths could be told about |
00:06:29 |
And, as I got deeper and |
00:06:30 |
I understood why there were so |
00:06:33 |
and that is because there were |
00:06:36 |
that had ever been found, |
00:06:38 |
no giant squid had ever |
00:06:41 |
until this day, has never been |
00:06:44 |
So, I became interested in trying |
00:06:48 |
just so I could tell the truth about |
00:06:55 |
The aura of terrifying mystery |
00:06:59 |
A report, by a French warship, |
00:07:03 |
fired the imagination of |
00:07:06 |
His classic 20,000 leagues Under the |
00:07:12 |
Verne's fictional squid updated the |
00:07:17 |
This squid did not hesitate |
00:07:21 |
Captain Nemo's electric submarine. |
00:07:36 |
"Giant squid astern, sir!" |
00:08:07 |
The terror of the giant squid |
00:08:10 |
but its mystery is very real. |
00:08:13 |
Once in a while, a giant squid |
00:08:17 |
Often, these are juvenile squid - |
00:08:20 |
more bizarre and pathetic |
00:08:24 |
Only an expert can tell its species, |
00:08:27 |
and that it could have grown to |
00:08:32 |
In modern times, more and more giant |
00:08:36 |
as they work in deeper water. |
00:08:39 |
They are almost always dead, or nearly so, |
00:08:42 |
when brought aboard. |
00:08:49 |
Rarely does a scientist get to |
00:08:52 |
and never a live one. |
00:08:56 |
Most have turned up in the waters |
00:08:59 |
Norway, and Newfoundland. |
00:09:01 |
This one, measuring more than 30 |
00:09:10 |
>From such fragmentary evidence, |
00:09:12 |
scientists conclude that giant |
00:09:16 |
and that they are predators. |
00:09:18 |
They are believed to live only a few |
00:09:22 |
no one knows how large. |
00:09:24 |
The biggest actually measured |
00:09:28 |
and weighed about a ton. |
00:09:30 |
It is the world's largest and most |
00:09:34 |
portrayed as a villain |
00:09:38 |
"Giant squid have a reputation |
00:09:41 |
and vicious and fierce." |
00:09:43 |
"They have no reason t be, uh, |
00:09:47 |
They normally don't interact |
00:09:50 |
Uh, in fact, I wish they would |
00:09:52 |
react with human beings |
00:09:55 |
At any rate, I think the reputation |
00:10:00 |
"Because they're so interesting, |
00:10:01 |
on their own account, that we don't |
00:10:07 |
"Squids are really exciting to me |
00:10:08 |
because they have wonderful |
00:10:11 |
for their life in the sea, |
00:10:14 |
like photophores or light organs, |
00:10:16 |
where they can flash and glow, |
00:10:19 |
they are fast animals; they're |
00:10:25 |
to collect their prey; uh, some |
00:10:33 |
Squid are weird and wonderful - |
00:10:35 |
they, and their close relatives, |
00:10:37 |
have been called "aliens |
00:10:41 |
Indeed, they ride the underwater |
00:10:44 |
that seems almost supernatural. |
00:10:54 |
Squid are remarkably intelligent, |
00:10:57 |
and their primary nerve fibers are |
00:11:01 |
a hundred times the diameter |
00:11:06 |
Thousands of multi-celled organs, |
00:11:08 |
called chromatophores, |
00:11:12 |
Each, receives signals directly |
00:11:18 |
This allows cuttlefish and squid to |
00:11:22 |
in less than a second. |
00:11:26 |
These changes in appearance |
00:11:30 |
and a dramatic means of |

The advanced nervous system |
00:11:49 |

Off the California coast, |

a submersible robot is lowered |

Below, is Monterey Canyon, |
00:12:17 |
the deepest submarine fissure along |
00:12:21 |
and probably the most carefully |
00:12:27 |
Scientists from the Monterey Bay |
00:12:31 |
have been studying life in |
00:12:34 |
for more than a decade. |
00:12:41 |
"Yeah... what's up here to the right." |
00:12:43 |
"Look at this guy, right up..." |
00:12:44 |
Any day, they could discover |
00:12:48 |
and they have observed many |
00:12:56 |
They have also observed species of |
00:13:00 |
in their natural element. |
00:13:02 |
Moroteuthis, a slender |
00:13:07 |
which grows up to 15 feet; |
00:13:09 |
Like the giant squid, almost |
00:13:20 |
Perhaps the strangest |
00:13:24 |
It's been called a "living fossil" |
00:13:27 |
and is completely covered with |
00:13:30 |
But whose exact function is unknown. |
00:13:34 |
It's a remarkable contortionist, |
00:13:37 |
presenting to its enemies |
00:13:44 |
The spikes are soft however and |
00:14:01 |
As varied and mysterious as they are, |
00:14:03 |
squid are short-lived, |
00:14:09 |
Shallow water species gather |
00:14:14 |
These tentacled couplings |
00:14:17 |
as males compete savagely |
00:14:39 |
Many die naturally soon after mating... |
00:14:41 |
if they don't fall victim to the |
00:15:11 |
Squid are among the most numerous |
00:15:15 |
and a crucial part of the oceanic |
00:15:19 |
Today, they support |
00:15:23 |
Some two million metric tons of |
00:15:28 |
much of it in Japan and the Far East. |
00:15:34 |
Small squid are the most |
00:15:37 |
But everyone has heard |
00:15:40 |
and it's gotten to be like |
00:15:43 |
for Japanese consumers. |

"Hungry? - Nissin Seafood Noodle." |
00:16:17 |
Mexico's Sea of Cortez: |
00:16:19 |
Every few years, squid of unusual |
00:16:25 |
Clyde Roper has come to investigate. |
00:16:36 |
The squid live in dark |
00:16:39 |
They rise close to the surface |
00:16:43 |
They're called Dosidicus gigas - |
00:16:49 |
For safety, Roper will deploy |
00:16:53 |
where he can find refuge |
00:16:58 |
This time of year, Dosidicus still |
00:17:03 |
But already, some are six feet |
00:17:05 |
at times, they feed like starving |
00:17:17 |
Roper has never seen Dosidicus |
00:17:21 |
but he's eager to have |
00:17:24 |
"They have, a, a, an incredible |
00:17:27 |
many of the fishermen say they |
00:17:29 |
fall into a uh, into the water with, |
00:17:32 |
in a feeding frenzy rather than in |
00:17:37 |
because they have been known |
00:17:39 |
when they fall into the water |
00:17:41 |
"There, here he comes. |
00:17:42 |
"In fact, they are so aggressive |
00:17:45 |
they become cannibalistic." |
00:17:48 |
A hungry squid immediately |
00:17:52 |
that is hooked and defenseless. |
00:17:55 |
Dosidicus often prey on one another - |
00:17:58 |
one thing that could account for the |
00:18:26 |
Some might consider this an |
00:18:29 |
but big squid like the Humboldt |
00:18:33 |
For Roper, the chance to see them in |
00:18:52 |
Like smaller squid, Dosidicus shows |
00:18:56 |
when aroused or threatened. |
00:19:09 |
Roper wants a close-up look- |
00:19:11 |
when the object of study can |
00:19:14 |
eight arms lined with powerful |
00:19:17 |
and a razor sharp beak. |
00:19:20 |
And all this is concealed at times |
00:19:24 |
deployed by squid to confuse |
00:19:36 |
Having a squid inside the shelter |
00:19:41 |
Roper tries to give it room to escape |
00:19:43 |
but gets a sharp nip from the |
00:19:47 |
"Ech!" |
00:20:04 |
Later, Roper feels bold enough |
00:20:07 |
and observe Dosidicus in open water. |
00:20:12 |
It is as close as he has ever |
00:20:14 |
what Architeuthis might be like |
00:21:09 |
"At first, I was quite apprehensive. |
00:21:12 |
Uh, it was a little scary. |
00:21:13 |
But we were dealing with mostly |
00:21:15 |
They were not in a feeding frenzy, |
00:21:20 |
"Oh, what a great animal. |
00:21:23 |
I was impressed at how incredibly |
00:21:27 |
Clyde Roper is not the first |
00:21:29 |
in the thrill of the hunt for big |
00:21:31 |
squid. |
00:21:32 |
"and to see the funnel so |
00:21:34 |
and moving out so fast, |
00:21:39 |
In the nineteen sixties, in fishing |
00:21:42 |
curious posters appeared. |
00:21:46 |
The reward for a giant squid was |
00:21:49 |
of the late Frederick Aldrich. |
00:21:52 |
An expert on mollusks, Dr. Aldrich |
00:21:56 |
where giant squid are a proud |
00:22:02 |
Back in October 1873, Newfoundland |
00:22:13 |
The squid wrapped a tentacle |
00:22:16 |
But one fisherman, |
00:22:19 |
quickly hacked the tentacle off, |
00:22:24 |
Only a month later, |
00:22:25 |
Newfoundland fishermen hauled |
00:22:35 |
This was the first complete specimen |
00:22:40 |
And it was the first of many |
00:22:43 |
by Newfoundland fishermen. |
00:22:46 |
But examining the dead was not enough |
00:22:50 |
he went after a live one. |
00:22:53 |
"Fred was really one of the first |
00:22:57 |
and try to find giant squid. |
00:23:02 |
"I think Fred liked the mythology |
00:23:03 |
and he liked the, the, the |
00:23:08 |
In 1989, Aldrich managed to mount |
00:23:12 |
to look for the giant squid. |
00:23:15 |
It was an enterprise that has been |
00:23:18 |
into an area of the United States |
00:23:21 |
and hoping to see a grizzly bear. |
00:23:24 |
But Aldrich was determined. |
00:23:33 |
The sub descended a thousand feet |
00:23:36 |
where giant squid have often |
00:23:39 |
It was literally a shot in the dark. |
00:23:45 |
Bait attracted an array |
00:23:52 |
For ten hours Aldrich watched |
00:23:57 |
but Architeuthis ignored |
00:24:03 |
I am not disappointed. |
00:24:04 |
The fact that I didn't see one |
00:24:06 |
does not effect my understanding |
00:24:10 |
I never really held out much hope |
00:24:14 |
because, oh, Lord, the ocean is so |
00:24:18 |
The brief expedition ended and |
00:24:27 |
As deep water technology |
00:24:29 |
there have been more |
00:24:31 |
that could encounter a giant squid. |
00:24:37 |
Many new species have been observed. |
00:24:40 |
And some have been seen that could |
00:24:54 |
This is the biggest shark ever seen |
00:24:58 |
A pacific sleeper shark that turned |
00:25:03 |
Well over 23 feet in length, |
00:25:05 |
it loomed so large the camera |
00:25:12 |
After investigating the sub for |
00:25:16 |
the giant went way, |
00:25:18 |
leaving observing scientists excited |
00:25:27 |
Once dismissed as mere |
00:25:31 |
the search for the giant squid |
00:25:32 |
continues to gain impressive |
00:25:36 |
One is Dr. Malcolm Clarke, |
00:25:38 |
a specialist in sperm whales |
00:25:41 |
"I think the good has always |
00:25:46 |
You, you see the beauty in, |
00:25:48 |
Many of, uh, the fish are |
00:25:52 |
to look at, uh, and, uh, have |
00:25:55 |
they make pretty lights. |
00:25:57 |
Uh, that's the beauty - |
00:25:58 |
you need a few big-teethed, |
00:26:01 |
big stomached monsters to go |
00:26:05 |
As a young graduate student, |
00:26:07 |
Malcolm Clarke conducted research |
00:26:10 |
that hunted sperm whales - |
00:26:12 |
once considered sea monsters, |
00:26:17 |
Little was known about sperm |
00:26:19 |
despite centuries of killing them. |
00:26:23 |
Only dwindling populations put |
00:26:27 |
to study the huge animals. |
00:26:30 |
Clarke inspected hundreds |
00:26:35 |
One thing he found were the beaks |
00:26:38 |
too tough to be digested. |
00:26:41 |
This proved that squid are the sperm |
00:26:46 |
And Clarke amassed a huge |
00:26:48 |
as many as eighteen thousand |
00:26:52 |
Among them, are many beaks |
00:26:57 |
"This came from a giant squid |
00:27:00 |
that was taken from the stomach of |
00:27:05 |
Uh, so that, uh, it wasn't a |
00:27:09 |
It was probably, uh, thirty, in |
00:27:13 |
So it was quite a big squid, but, |
00:27:17 |
Uh, but certainly, it's got |
00:27:21 |
So that this is very, |
00:27:23 |
And, uh, of course, if they did live |
00:27:28 |
they would make mincemeat |

On a remote shore in New Zealand, |

00:27:47 |
and discover evidence of their |
00:27:53 |
The skins of sperm whales are like |
00:27:58 |
The circular scars were left by |
00:28:02 |
marking their last desperate |
00:28:04 |
in the jaws of the Leviathan. |
00:28:08 |
"They have fifty teeth. |
00:28:10 |
These are in a, uh, form two rows |
00:28:14 |
They don't have any upper |
00:28:16 |
Uh, but the jaw is very, very narrow. |
00:28:19 |
It can be about fifteen feet long |
00:28:23 |
So, it's very, very long and narrow. |
00:28:25 |
Uh, and it's a snapping jaw, it's |
00:28:29 |
It can probably, uh, snap shut |
00:28:32 |
and they snap this jaw against |
00:28:35 |
Bang! |
00:28:36 |
And, in that movement, |
00:28:39 |
and it doesn't matter that the |
00:28:42 |
the squid will virtually |
00:28:45 |
They, they don't like being |
00:28:48 |
It's one of their features - |
00:28:50 |
And, uh, if they're squeezed |
00:28:54 |
and there's a big, very powerful |
00:28:59 |
to push it down the throat. |
00:29:01 |
Experts on both whale and squid, |
00:29:07 |
to execute a new strategy |
00:29:11 |
"Whales were known to feed on squid |
00:29:16 |
in the earliest days of, uh, |
00:29:20 |
and some of those |
00:29:23 |
So it made sense to me to try to use |
00:29:28 |
to, to lead us to, to the giant squid |
00:29:31 |
and that quest has brought on |
00:29:35 |
Off the Azores, |
00:29:36 |
Roper and Clarke help to deploy a |
00:29:41 |
They, and the other scientists on this expedition, |
00:29:44 |
are combining their search for |
00:29:47 |
with research on |
00:29:55 |
Hydrophones can detect the sounds of |
00:30:00 |
- long before they can be |
00:30:03 |
But the whales themselves |
00:30:06 |
and often keep their distance |
00:30:21 |
Today, the scientists are in luck. |
00:30:24 |
The whales are feeling sociable. |

00:31:02 |
It is an audience clapping. |
00:31:05 |
And they're clapping at us. |
00:31:11 |
When sperm whales gather, |
00:31:20 |
A distinct series of clicks is called |
00:31:34 |
Deciphering the sounds is a challenge |
00:31:36 |
for behavioral experts like |
00:31:43 |
"Now that's one of the unknowns. |
00:31:45 |
That could very well be used |
00:31:53 |
Sometimes divers can get very close |
00:31:58 |
It's a tremendous thrill |
00:32:01 |
by the most powerful predators |
00:32:05 |
Up close, |
00:32:10 |
This loud and singular noise |
00:32:14 |
or even a weapon |
00:32:26 |
The sperm whale's head is |
00:32:30 |
and most of it is nose |
00:32:37 |
This is where the sounds are created. |
00:32:40 |
They're generated |
00:32:42 |
then redirected as they resound |
00:32:47 |
No one knows exactly how. |
00:32:51 |
This remarkable organ also holds |
00:32:56 |
By regulating its temperature, |
00:32:58 |
the whale may be able |
00:33:03 |
This would allow them |
00:33:05 |
on their long dives to hunt for squid. |
00:33:11 |
In any case, |
00:33:13 |
the whales seem in perfect control |
00:33:16 |
- suspended virtually |
00:33:21 |
This remarkable behavior has only |
00:33:45 |
Mother sperm whales are |
00:33:48 |
Their calves are slow to mature. |
00:33:52 |
They stay in close contact |
00:33:55 |
but their ability to dive is limited. |
00:34:00 |
A mature female needs more than |
00:34:05 |
and her food source |
00:34:09 |
may be thousands of feet below. |
00:34:12 |
So she must leave her calf |
00:34:15 |
- sometimes for almost an hour. |
00:34:20 |
The calves are |
00:34:24 |
and will often approach |
00:34:28 |
This one offers its mouth |
00:34:48 |
The mother can go down |
00:34:50 |
- a plunge deep into the unknown. |
00:34:55 |
"We really don't know |
00:34:59 |
how they hunt, |
00:35:01 |
and how they actually |
00:35:04 |
There are several hypotheses: |
00:35:05 |
one is that they use echolocation |
00:35:11 |
Somehow sperm whales "see" the world |
00:35:14 |
through a panorama |
00:35:23 |
This certainly helps them |
00:35:26 |
but can they detect and catch |
00:35:31 |
The scientists seek |
00:35:34 |
"They can use the, |
00:35:39 |
that might be created |
00:35:43 |
or by the squids |
00:35:45 |
and creating a swirl of |
00:35:50 |
"When they swim through the water |
00:35:51 |
they disturb all the little organisms |
00:35:56 |
and these little organisms, |
00:35:59 |
set off a glowing or flashing. |
00:36:08 |
"Perhaps the whales then key |
00:36:13 |
or streaks of bioluminescence |
00:36:14 |
and will be able to home in |
00:36:18 |
"So, it's a little difficult |
00:36:21 |
and that's just one more thing |
00:36:23 |
if we could get down into the sea |
00:36:27 |
To follow whales into the deep |
00:36:29 |
has long been a favorite theme |
00:36:34 |
Now, with support from |
00:36:38 |
one man has managed to do it. |
00:36:40 |
He's Greg Marshall, |
00:36:45 |
It's a simple concept that has proven |
00:36:50 |
"I had the idea for the crittercam |
00:36:53 |
Since then, basically, |
00:36:56 |
I've spent thinking about, developing, |
00:37:01 |
In early experiment, |
00:37:02 |
cameras were strapped |
00:37:05 |
before being risked in the wild. |
00:37:09 |
"What motivates me is the, |
00:37:10 |
the possibility of discovering |
00:37:15 |
seeing things |
00:37:20 |
The spirited fur seal |
00:37:24 |
A smaller, more rugged camera |
00:37:42 |
With sperm whales, |
00:37:43 |
every step |
00:37:46 |
has been fraught with difficulty. |
00:37:48 |
"It's only through, you know, |
00:37:52 |
and then some trial and error |
00:37:55 |
the field that we've, that we've finally been able to succeed |
00:37:57 |
in the way that we have." |
00:38:05 |
After years of experimentation, |
00:38:07 |
crittercam is finally ready for |
00:38:12 |
The scientists are hopeful that the |
00:38:16 |
and be located |
00:38:19 |
"Um, underwater it weights nothing, |
00:38:21 |
so that, uh, it just floats right back |
00:38:24 |
Floats back at about |
00:38:26 |
uh, will stick out of the water |
00:38:28 |
The system must be able |
00:38:32 |
and record picture |
00:38:37 |
The compact unit includes lights; |
00:38:42 |
temperature and sound; |
00:38:46 |
and a video camera able to |
00:39:00 |
"Greg! Come over!" |
00:39:07 |
The first task is often the hardest |
00:39:33 |
"You guys, |
00:39:35 |
Scientists have used these techniques |
00:39:39 |
but no one has tried |
00:39:43 |
They are breaking new ground. |
00:39:47 |
"It was a challenge to get close |
00:39:50 |
an emotional challenge. |
00:39:51 |
Uh. Clearly, we'd heard |
00:39:55 |
that the sperm whales had wreaked |
00:39:58 |
you know, I, I didn't know, |
00:39:59 |
what, uh, reaction of a, |
00:40:02 |
So, when we first started approaching |
00:40:04 |
I was a bit nervous, |
00:40:12 |
The camera can be attached |
00:40:16 |
- or with a large suction cup. |
00:40:25 |
A successful deployment depends |
00:40:30 |
At the moment, they appear to want |
00:40:36 |
"We spend a lot of time on the water |
00:40:39 |
a lot of time on the water, |
00:40:42 |
the whales are only at the surface |
00:40:46 |
Uh, so we have to be perfectly |
00:40:48 |
anticipating where the whales |
00:40:51 |
in order to place ourselves |
00:40:53 |
so that we can get to them |
00:41:04 |
"You've got whales, uh, |
00:41:06 |
They'll be off you, uh, starboard bow, |
00:41:10 |
Uh, there's a whole gaggle of them, |
00:41:13 |
Three or four small ones |
00:41:18 |
"What we've found, |
00:41:20 |
is that the whales tend to be |
00:41:23 |
If we're quiet in their environment, |
00:41:27 |
as often as not, they tend to actually |
00:42:00 |
The system is launch- |
00:42:07 |
The clicking noises are made |
00:42:10 |
and for the first time |
00:42:11 |
we can see exactly how their sounds |
00:42:21 |
It's a revelation |
00:42:24 |
in their constant calling and |
00:42:41 |
Then, as dolphins join the array, |
00:42:47 |
They sometimes |
00:42:49 |
generated by the forward thrust |
00:42:53 |
- these mountains of movement. |
00:43:26 |
Crittercam is working well |
00:43:29 |
Now comes the real test |
00:43:33 |
They will disappear for |
00:43:39 |
The scientist are left alone |
00:43:44 |
"If we don't retrieve the system, |
00:43:47 |
we get none of the images, |
00:43:50 |
Unless we recover it, it's a bust." |
00:43:57 |
A messenger form another world, |
00:44:11 |
It has detached before |
00:44:13 |
but its homing signal is |
00:44:26 |
After eleven year of trial and error |
00:44:30 |
a moment of truth has arrived. |
00:44:43 |
"Look at that, look at that, |
00:44:46 |
That's the... the blowhole |
00:44:51 |
The camera is tethered about six feet |
00:44:56 |
- we are with several whales |
00:45:07 |
On the right, a juvenile. |
00:45:09 |
This could be a training dive. |
00:45:11 |
Calves only gradually learn to dive |
00:45:17 |
The clicking sounds appear to be |
00:45:25 |
Some scientists believe that |
00:45:31 |
Tapes like this one could help |
00:45:37 |
It's darker and deeper now |
00:45:39 |
and another whale |
00:45:45 |
Strange new sounds are heard |
00:46:03 |
No one has conclusively identified |
00:46:11 |
Now the whales are over nine hundred |
00:46:17 |
They almost stop and one moves back |
00:46:22 |
it's head and eye are just |
00:46:31 |
There is a long moment |
00:46:34 |
apparently satisfied, |
00:46:36 |
the whales speed up again, |
00:46:51 |
There's two, |
00:46:53 |
This is the calf. |
00:46:57 |
1200 feet-at this depth |
00:47:01 |
over five hundred pounds |
00:47:04 |
Until the 1960's, |
00:47:06 |
no conventional submarine |
00:47:09 |
without being crushed |
00:47:13 |
How sperm whales survive |
00:47:18 |
But they've been doing it |
00:47:21 |
- lured here by vast bounty of |
00:47:29 |
They will not find Architeuthis |
00:47:31 |
but each moment is a revelation |
00:47:36 |
"The interesting thing here, |
00:47:38 |
you can, you can hear that these |
00:47:42 |
um, each one is |
00:47:44 |
and every once in a while |
00:47:48 |
"Now the whales have stopped. |
00:47:50 |
The, the camera is pointing |
00:47:52 |
uh, right down into the skin |
00:47:55 |
that's, uh, that's carrying |
00:47:59 |
"There see, now I'm hearing that, |
00:48:07 |
That's fantastic, that's so... |
00:48:12 |
Yeah, that's a fantastic sound, |
00:48:19 |
uh, this is, uh, what, we believe is |
00:48:23 |
when they're actually hunting, |
00:48:25 |
or have actually picked up |
00:48:28 |
and they're zeroing-in on the prey |
00:48:39 |
"Now they're starting |
00:48:43 |
uh, have turned and turned back |
00:48:46 |
because now we can see, |
00:48:48 |
uh, the background that's lighted. |
00:48:50 |
So they're heading back up |
00:49:05 |
"Whoa! There comes |
00:49:08 |
another one, |
00:49:12 |
"There's two more. |
00:49:13 |
Look at that!" |
00:49:19 |
"And there's a, there's a third one |
00:49:22 |
So, that makes four whales... |
00:49:33 |
The, the crittercam has been |
00:49:35 |
that's how closely, uh, the whales were |
00:49:38 |
really rubbing along, |
00:49:45 |
No giant squid was found. |
00:49:48 |
But this and other crittercam dives |
00:49:54 |
"We were able, |
00:49:56 |
to enter into the deep-sea domain |
00:50:00 |
By playing these instrument |
00:50:03 |
we were able to get down to |
00:50:06 |
and how the animal actually behaves |
00:50:14 |
But the sperm whales seem blissfully |
00:50:18 |
and understand their world. |
00:50:20 |
They have appointments |
00:50:24 |
which we can still see |
00:51:53 |
One day, |
00:51:56 |
a whale may bring us |
00:52:02 |
and one of the last great challenges |
00:52:05 |
and photography will be met. |
00:52:08 |
But for the moment, |
00:52:09 |
we must contemplate these great whales |
00:52:13 |
fascinated by their physical powers, |
00:52:15 |
tantalized by the secrets they hold |
00:52:23 |
Two-thirds of our planet lies |
00:52:27 |
and that mysterious realm |
00:52:35 |
In search of the giant squid, |
00:52:37 |
Clyde Roper and his colleagues seem |
00:52:43 |
- happily engrossed in the hunt |
00:52:49 |
Perhaps there is much truth |
00:52:53 |
that men need sea monsters |
00:52:59 |
that an ocean |
00:53:01 |
would be like sleep without dreams. |
