Las aguas salvajes de Alaska son un ecosistema fascinante y a la vez aterrador, donde habitan algunos de los animales marinos más mortíferos del planeta. En este entorno inhóspito, las mandíbulas feroces de criaturas como orcas y tiburones salmón emergen del mar, revelando su ferocidad en la búsqueda de presas. Estas majestuosas bestias no solo son cazadores imponentes, sino que también juegan un papel crucial en el equilibrio del ecosistema marino. Las costas de mar abierto de Alaska crean un camino ideal para estos gigantes, mientras que los canales de aguas profundas esconden pequeñas pero letales especies que utilizan sofisticadas armas naturales para sobrevivir. Desde criaturas que aturden hasta aquellas que inyectan veneno, cada ser tiene su propia estrategia para enfrentar los desafíos del océano.
Además de su impresionante diversidad, las aguas salvajes de Alaska son un recordatorio de la fragilidad del equilibrio ecológico. La interacción entre los grandes depredadores y las especies más pequeñas ilustra cómo cada criatura, sin importar su tamaño, tiene un papel importante en el mantenimiento de la salud del ecosistema. Por lo tanto, es fundamental que se tomen medidas para proteger estas aguas y sus habitantes. El estudio y la conservación de estos entornos únicos son esenciales para asegurar que las futuras generaciones puedan disfrutar de la maravilla de las aguas salvajes de Alaska.

00:00This is Alaska, home to some of the deadliest predators on the planet.
00:11Although we rarely see or think of these hunters with detainment.
00:19Some of the fiercest animals in this area live under the sea.
00:28The sea of Alaska is an extreme environment.
00:34It is cold, dark and competitive.
00:43The only way to survive is to kill.
00:51The deadliest of Alaska, the kingdom of the killer whale.
01:05When night falls, a monster shakes the depths of the sea.
01:13The giant squids are usually solitary.
01:23Except when the same thing happens to all of them.
01:30Tonight, the army rises to hunt in shallow waters, in total darkness.
01:37Their eyes, the size of billiard balls, can see perfectly at night.
01:44A squid can reach the size of a person and weigh up to 45 kilos.
01:52They are very intelligent and communicate in the dark, making flashes with their skin.
02:02With their ten tentacles, suction cups and teeth that tear the flesh,
02:09they drag their victims towards an implacable mouth.
02:17And when there is not enough food, they eat each other.
02:30They are cannibals.
02:37A splash of defense ink is too little and too late.
02:45At dawn, the frenzy calms down and they return to the depths.
02:52The sea is calm again.
02:59The sea is calm again.
03:04The sea is calm again.
03:09The sea is calm again.
03:16The sea is calm again.
03:23The sun awakens a world of fighting creatures.
03:30The shallow waters of Alaska are home to a frenzied army race.
03:38Here lives a voracious marine predator, the starfish.
03:45There are around 2,000 species, most with five arms.
03:51But the sunfish star is endowed with the largest number of arms, up to 24.
04:09This predator senses and smells its way with 15,000 suction cups
04:16and moves at a speed of almost one meter per minute.
04:22In the slow world of the seabed, it is a speed of heart attack.
04:28At least for its prey.
04:36Like this starfish.
04:45It has its own transport method.
04:49A very powerful foot.
04:55Although a step in the wrong direction can be its death sentence.
05:02But even the voracious starfish has its own enemy.
05:25This gigantic beast is a centipede from the Puget Strait.
05:33With its tenacity, it catches one of the 19 arms of the starfish.
05:40But the starfish has an ace up its sleeve.
05:45Get rid of its own limbs.
05:50It is a predator of the sea.
05:55It is a predator of the sea.
06:00It is a predator of the sea.
06:06Get rid of its own limbs.
06:12The centipede has its dinner.
06:17And the starfish escapes alive and with spare limbs.
06:27In Alaska, the best hunter is the one who can hide at first sight.
06:36And no one does it better than this camouflage queen.
06:47It is a giant octopus from the Pacific.
06:53It has a calculating intelligence.
06:58And rightly so.
07:00It has nine brains that have almost 500 million neurons.
07:05Almost twice as many as a domestic dog.
07:13One brain is in the head.
07:16And each arm has its own brain to control the movement.
07:23It is driven by three hearts that pump blue blood rich in copper.
07:31Today, feeding is its priority.
07:35It is already older than a human.
07:38But it is getting ready for its big moment.
07:44With its gift for invisibility, it prepares the ground for a crustacean apocalypse.
08:03This crab is going to take the surprise of its life.
08:14That is not a rock.
08:23The octopus paralyzes its prey with poison injected with a hidden beak.
08:30There is no escape from that attack.
08:36The 280 tentacles per arm can taste and grab.
08:46Although they only live about four years, the Pacific giant octopuses can reach six meters long and weigh up to 90 kilos.
08:57A body like this needs many crabs.
09:05But it is not enough.
09:10It needs more.
09:15It needs more.
09:19It needs more.
09:23It needs more.
09:27It needs more.
09:31It needs more.
09:38Although it is full, it continues to hunt, reserving live crabs for later.
09:53Now that it has energy, it is ready for its last disappearance.
10:01It has more than 50,000 fertilized eggs.
10:06And it has to find a place from which it can defend them.
10:17This cave is perfect.
10:22Here, it gathers its thousands of eggs, the size of rice grains, and sticks them to the walls.
10:34For six months, it does not stop pumping water to the eggs to clean them of parasites.
10:44It cannot leave them, not even to eat.
10:49Its color fades and it loses half of its body weight.
10:57This fearsome queen is weak and at a disadvantage to protect its eggs.
11:06And irresistible to the sunflower star.
11:19And this time, it has brought a friend.
11:24It has come to compensate for its devoured limb.
11:29It must find the strength to defend its children.
11:48First, it pumps water over the eggs to help them free themselves from their shells.
12:06Then, it makes the final sacrifice.
12:19Its corpse will serve as bait and keep the bandits away from its little ones.
12:35They need all the possible help.
12:40Of the tens of thousands that hatch, only two will survive.
12:45They are nothing compared to the vast ocean in which they were born.
13:03The coast of Alaska is the longest in the United States, about 80,000 kilometers.
13:14When we think of Alaska, we imagine endless forests.
13:20But some of the most abundant forests are underwater.
13:31The algae forests are less known than the Californians, but they are just as rich.
13:45It is the home of the colorful sea hedgehog,
13:49whose 12-centimeter fangs help to keep most predators away.
13:56Except for this one.
13:59The wolf eel.
14:03Which is neither a wolf nor an eel.
14:15It is a two-meter fish with a voracious hunger.
14:24And it is as terrifying as it seems.
14:45Its ferocious teeth are worn out by years of ending the life of prey of great robustness.
15:00The strength of its bite is one of the greatest in nature
15:05and can pulverize animals of hard shell in seconds.
15:15It has a strong jaw and a terrifying appearance, but it has a romantic side.
15:22And this is the object of its affection.
15:26The lady in red.
15:34The wolf eel.
15:38The lady in red.
15:56And she likes her tough look.
16:00Soon they will start a life together.
16:04The wolf eels have a life partner and will live in the same rocky lair forever.
16:12But the honeymoon lasts short.
16:18The wolf eel cave is soon filled with children.
16:27With 10,000.
16:30It is full.
16:33And the parents spend most of the time protecting their family from possible predators.
16:42At last, the day comes for the wolf eels to go out to the ocean.
16:48Although few will survive.
16:52Those who do it will end up looking for a good rock and their own partner.
17:11Luckily, they will end up being like their parents.
17:15Devoted companions for the rest of their lives.
17:25For migratory animals, home is nothing more than a memory.
17:31The salmon of Alaska spends most of its life far from home.
17:37They swim thousands of kilometers in the ocean.
17:40But at the end of their lives, their goal is to return to their place of birth to hatch.
17:48The magnetic field of the earth guides them.
17:52They use it as if it were a map.
17:56They know the route according to the magnetic field in which they are.
18:01And when they get closer, they realize that it is a map.
18:06But first, they must avoid the biggest predators of Alaska.
18:14And the most fearsome is the one that receives the most appropriate name.
18:19The salmon shark.
18:22It has arrived in Alaska, but it has not yet found its home.
18:27It has to find a new home.
18:31The salmon shark.
18:34The time has come.
18:37They have also traveled thousands of kilometers.
18:42The salmon cling to the walls of the fjords, trying to dodge the sharks.
18:49But instead of being a safe step, the rocks increase the risk.
18:54Unlike their cousins, the great white sharks, the salmon sharks hunt on benches.
19:01Together they push the salmon against the walls of the fjords,
19:05and lead them to the surface, thus eliminating their escape routes.
19:17The shark fails the first attempt.
19:20But resistance is its specialty.
19:30Swimming in small circles around the salmon will make them tired.
19:36At least, that is the plan.
19:50Another failure.
19:53It decides to give up the gym and resort to persecution.
20:00The salmon shark has an extraordinary sight.
20:05It has very separate eyes, so its sight is binocular to locate its prey.
20:14A huge advantage to get close to the fast salmon.
20:20They can reach up to 80 kilometers per hour,
20:24and they are one of the largest and fastest fish on the planet.
20:39When the festival begins,
20:42the salmon shark is ready to go.
20:46The sharks are relentless,
20:49and dive into those waters full of salmon.
21:15Like the wolves, a bank of sharks attacks at the same time,
21:19devouring everything that crosses its path.
21:46And storing energy to reproduce,
21:50migrate, and for the days of food shortage.
22:03The salmon that manages to escape unharmed, continues through the area between tides.
22:09Where the ocean and the rivers merge into the streams of fresh water.
22:24But before the salmon can swim upstream,
22:28it must adapt to the mixture of fresh water.
22:39After traveling hundreds of kilometers,
22:43they are very close to achieving their goal.
22:49They only have one obstacle left to overcome.
22:55A corridor of large predators.
23:03The brown bears have calculated perfectly the moment of their arrival.
23:09They must get fat and prepare to hibernate.
23:31And these osethnos are learning valuable fishing lessons.
23:39The mother makes it seem easy.
23:47It is the first time that the osethnos have food in front of them that tries to escape.
24:09They are the fish that make these bears the biggest in the world.
24:18Salmon have a high level of calories,
24:22and in shallow waters they are very easy to fish.
24:30The salmon are the only fish that can survive.
24:39But these are only shooting practices.
24:51The main course is further away.
25:01Bears have an incredible sense of smell.
25:03In many occasions, it is better than that of dogs,
25:07and thousands of times better than ours.
25:12A hungry grizzly bear smells an unexpected opportunity.
25:18They have touched the earth with millions of calories.
25:26A humpback whale.
25:34Grizzlies are usually solitary,
25:38but the smell brings them together from miles away.
26:03They are not used to sharing.
26:33The last ones to arrive are not welcome.
27:03They stay with the worst part of the whale,
27:07at a safe distance from the rest.
27:33The tail does not feed too much,
27:37but it can only wait.
27:47Soon, the rest of the bear eats its share,
27:51and a little more.
28:03It is like when Christmas comes.
28:34As everyone is tired of eating,
28:38the hungry male is served for a few seconds without stress.
28:54The bears, who have not been misled by the unexpected stroke of luck,
28:59follow the salmon upstream, towards the desert area.
29:09The increasingly narrow rivers
29:12concentrate the salmon in the water where they were born.
29:29This is where the next generation is created,
29:33in a mass desolation.
29:38The parents have already fulfilled their role.
29:42Forever.
29:59Each female lays about 1,500 eggs,
30:03but few reach adulthood.
30:09While the bears fish for salmon,
30:13others look for offspring.
30:17A gigantic swarm prepares to invade the waters of Alaska.
30:21Thousands of jellyfish arrive in groups.
30:24A giant lion's mane jellyfish joins them.
30:30They have arrived at the right time,
30:34when the temperature and currents are perfect
30:38for the explosion of salmon eggs.
30:42They are an unstoppable fleet of hungry and jellyfish predators.
30:55The poisonous tentacles inject toxins into their prey,
30:59leaving them defenseless.
31:03The tentacles catch the eggs and take them to their mouths,
31:07in the middle of their bellies.
31:15The eggs that survive the attack grow
31:19until they become miniature versions of their parents.
31:24They hatch in the great blue,
31:28where they hunt some of the largest creatures in Alaska.
31:49Just in time,
31:53humpback whales and orcas arrive at this summer buffet.
32:08Orcas eat everything.
32:16Today, they crave a humpback whale.
32:23And they go for the offspring.
32:38Orcas are experts in ambushes.
32:41First, they surround the group of humpbacks.
32:57Then, they separate the mother from the offspring.
33:12And finally, they catch the calf and drown it.
33:15The predators are hungry.
33:19So they go for the offspring.
33:45Orcas are the easiest prey.
33:49The tongue and the tender lips of the humpback whale.
34:08The ingenious orcas dismantle the corpse,
34:15and keep it in the background for later.
34:34The extreme conditions of Alaska inspire the hunters to innovate.
34:41The competition is tough.
34:44But cooperation usually yields wonderful rewards.
34:49Humpback whales also do it.
34:55In fact, they are famous for collaborating with each other.
34:59They use sophisticated communication skills to hunt in groups.
35:07Each member of the hunting group has a specific function
35:10within the group hunting ritual,
35:14called the food bubble network.
35:19Today's lunch is harenkes.
35:29A whale is located under the fish.
35:33It is the explorer and the one that blows bubbles.
35:37When it finds the fish, it blows a curtain of air,
35:41which goes up in a spiral and surrounds the bench.
35:50The frightened fish group up.
35:55Then, the leader indicates to the others
35:59who are on the surface, in unison,
36:02with their mouths open, to catch their prey.
36:07Working as a team,
36:10each whale can consume thousands of fish in one sitting.
36:16A very clever strategy,
36:19to make the most of this little gift.
36:26The sea ice that once enveloped the coast is melting.
36:37The sea ice is melting.
36:50Humpback whales rest in their floating apartments.
37:01But their platforms are getting smaller and smaller,
37:04which makes them get in a bad mood.
37:14They leave their half-melted pieces of ice
37:18to look for food and dry land.
37:28Now, one of Alaska's largest marine mammals
37:31competes against time.
37:40If it has nothing solid to rest on,
37:44the morsa can drown in Alaska's icy waters.
37:53Like the males, the females and the young
37:57also deal with their melted shelters.
38:02In Alaska, even the largest young
38:06are born without experience and defenseless.
38:14This young, with less than a day to live,
38:18needs a swimming class urgently.
38:22It's a serious matter.
38:26The mother and her young begin to look for land,
38:30and the little one has to keep up the pace.
38:51After swimming for miles, they finally reach a rest stop.
39:22But there's a problem.
39:26It's a beach full of very irritable males.
39:36The mothers are too tired to touch the ground
39:40and sleep in the water with their children.
39:44After regaining their energy,
39:48the mothers and their young finally leave the sea.
39:56But the danger is still there.
40:00There are 20,000 morsas stretching on the slopes.
40:03They are too many,
40:07and they end up fighting each other.
40:34There are creatures that weigh up to two tons,
40:38climbing a sea full of flesh and fangs.
40:52These are dangerous moments for the morsa young.
40:56Some try to climb on their mothers' backs
41:00to escape the fighting.
41:14The furious mothers fight the threats for their babies.
41:26But the coast trembles,
41:30and the bodies shrink, reducing the space around them.
41:40This young is no match for the two-ton males
41:44that increase the pressure.
41:55Not even the water is safe.
42:26The mothers and their young
42:30have no choice but to fight back.
42:34The mothers and their young
42:38have no choice but to fight back.
42:56The summer in the Arctic is short,
43:00and the ice begins to form again,
43:04which frees them from the dangers of the beach.
43:11The mothers can escape with their vulnerable young.
43:26They return to the sea.
43:45The young will stay with their mothers for another two years,
43:49learning life lessons
43:52that will help them survive in this harsh land.
