00:00 Everybody knows sharks as the top predator in the ocean.

00:08 Look at this dangerous looking.

00:10 Sharp teeth, scary eyes, injured face.

00:14 But that's wrong.

00:15 The real king of the ocean is the killer whale.

00:22 The killer whale is at the top of the ocean food chain.

00:27 Killer whales do not even have natural predators in the ocean.

00:31 There is no animal in the ocean that can stand up to killer whales.

00:36 Killer whales are social animals.

00:38 They hunt in groups.

00:40 They are so intelligent that you wouldn't even believe their plans to hunt animals.

00:46 This group of orcas is creating waves to wash that seal to the ocean.

00:56 After it falls in the ocean, the rest is easy.

00:59 Catch and eat.

01:05 Orcas eat nearly everything in the ocean.

01:07 Fish, seals, sharks, sometimes other whales.

01:12 On the coast of California, people witnessed two orcas are killing a shark.

01:18 Orcas kill great white sharks and eat just the liver.

01:21 They leave the rest of the body.

01:23 There are several occasions people have found sharks' livers taken off.

01:29 Terrifying.

01:30 The reason is probably orcas see shark livers as vitamin pills.

01:38 Orcas have a crucial part in the ocean food chain.

01:40 When they do not hunt their prey, it will affect the whole ocean consequently.

01:46 If they stop hunting, the number of sharks/seals will increase above normal levels, which brings

01:52 out bad news for the whole ocean ecosystem.

01:56 The name "killer whale" was given to orcas after ancient sailors observed groups of orcas

02:02 hunting and preying on larger whale species.

02:05 They referred to orcas as "assassina valenas" or "whale killers", a term that was eventually

02:12 shortened to "killer whale".

02:14 Orcinus orca, the Latin name for orcas, reflects this observation of orcas feeding on large

02:21 whales.

02:22 We talked about great whites a lot.

02:24 Let's take a look at them too.

02:26 Smell accounts for up to two-thirds of the total weight of a shark's brain.

02:31 Some sharks can detect prey blood from a great distance away.

02:36 One drop of blood to one million drops of water.

02:39 That's equivalent of one teaspoon in a medium-sized swimming pool.

02:44 Their sharp teeth can cut almost anything like a knife.

02:48 These triangular teeth are specifically designed to kill prey.

02:52 Great white sharks like to hunt sea lions, sea turtles, seals, dolphins, small-teethed

03:00 whales, seabirds.

03:02 They use a common strategy to hunt prey underwater.

03:05 They approach prey from underneath and with a high burst of speed, they can even leave

03:11 the water completely.

03:13 Let's check out another animal in the ocean food chain, polar bears.

03:17 Even though they are in the category of land mammals, polar bears are considered as good

03:23 swimmers.

03:24 They spend most of their time underwater.

03:26 They can swim for hundreds of miles from the land without giving a single break.

03:31 Their first choice is usually seals.

03:34 But they eat fish, delugas, narwhals, walrus, and sometimes bobhead whales.

03:41 What happens when they cannot get in the sea?

03:43 They search for bird eggs.

03:46 Seals are the favorite meals of polar bears.

03:49 They can wait for days for a seal to get out of a breathing hole.

03:53 When the seal pops out for air, the polar bear jumps in the hole.

03:58 Another predator in the ocean, leopard seals.

04:01 Even though leopard seals look so cute, they are ferocious predators.

04:06 With their powerful jaw and long sharp teeth, they can easily rip apart seal pups and penguins.

04:13 They are the Antarctic's fearless predators.

04:16 When they catch a penguin, they swing it left and right until its skin is peeled off.

04:23 Unlike their looking, they are quite horrible.

04:27 They have an insatiable appetite.

04:29 They spend most of their time in the ocean foraging for prey.

04:33 They eat almost anything that moves in the ocean, fish, squid, crustaceans, and thousands

04:39 of prairies.

04:41 In the ocean, there is an important predator that should not be forgotten on this list.

04:46 Sea lions.

04:48 Sea lions can swim faster even than sharks and killer whales.

04:52 They can swim at burst speeds up to 25 miles per hour.

04:56 However, they still can't resist the evil plans of sharks and killer whales.

05:02 They are threatened by killer whales and sharks in the ocean and by humans on the land.

05:09 Especially the baby sea lions that cannot swim fast enough will be prey for these predators.

05:16 Their best defense strategy is getting onto the land.

05:19 But sometimes even this strategy cannot save them from killer whales.

05:28 We talked about predators, but what about the owners of the oceans?

05:34 Meet the biggest animal in the world.

05:36 The Antarctic blue whale is the world's largest animal, weighing up to 400,000 pounds.

05:43 This equals to approximately 30 elephants.

05:46 They can reach lengths of up to 98 feet.

05:50 The whale has a heart the size of a small car and consumes approximately 8,000 pounds

05:55 of kernel per day during the main feeding season.

06:00 It is the loudest animal on the whole planet, even louder than a jet engine.

06:06 With calls reaching 188 decibels compared to 140 decibels for a jet.

06:13 Low-frequency whistle of the whales can be heard for hundreds of miles and is most likely

06:19 used to attract other blue whales.

06:22 They travel a lot, spending the summers feeding in the polar regions and then making a long

06:27 journey to the equator as winter approaches.

06:31 They have a cruising speed of 5 miles per hour, but can accelerate to 20 miles per hour

06:37 when necessary.

06:39 The blue whale can be found in every ocean on the planet, which means it can be found

06:44 in every aquatic habitat.

06:46 They have been discovered in Arctic, tropical, subtropical, and temperate seas.

06:53 These whales spend the summers in the cooler waters of the Arctic and Antarctic oceans

06:59 and the winters in tropical waters near the equator.

07:02 The older whales and pregnant whales are the first to set out on their migration.

07:08 In general, migration occurs in groups based on age and sex, with the youngest animals

07:14 migrating last.

07:20 During the migration, they eat almost nothing and rely on their fat reserves to survive.

07:28 When whales reach tropical waters, they give birth and reproduce.

07:33 Every two to three years, these whales have a calf and carry the baby for about a year.

07:39 After a year of gestation, the whale gives birth to a calf, which is about 23 feet long

07:45 and weighs between 5,000 and 6 pounds at birth.
