00:06In Botswana's Okavanko Delta
00:10There is a hidden underwater world
00:14The rice paddies here are infested with maggots.
00:15The river is densely branched
00:17Maintaining the original state of nature
00:20Let this largest inland delta in the world
00:23It has become a paradise for numerous wild animals and plants.
00:39Today, a team has ventured deep into this remote waterway.
00:43Tanzan Okavanko River
00:46The impact of Botswana's River of Life on the Delta
00:54The Okavanko River provides abundant water to this delta.
00:59It also allowed the creatures here to experience the baptism of life.
01:16This is the underwater world of the Okavanco Delta.
01:37When Botswana is in its dry season
01:40The overflowing Okavango River and its waters would then flow into this tropical swamp.
01:44land
01:47Thirsty wild animals in search of water
01:50They will migrate here in droves
01:59The floodwaters arrive at the Okavanko Delta as scheduled every dry season.
02:07It provides a means of survival for the animals in the surrounding area.
02:11water source
02:15The spectacular scene of large-scale wildlife migration
02:17It attracts tourists from all over the world every year.
02:25But some dangerous animals also live here.
02:28Enough to make people hesitate
02:38Nirohe guarded his territory
02:50This body of water is always fraught with danger.
02:56Local hunters try to avoid hippos.
02:59Because hippos can easily capsize their canoes.
03:05Going into the water without warning is definitely not a wise move.
03:34With extensive biological knowledge and understanding of the underwater behavior of dangerous animals
03:38Unique understanding
03:40A local setup team conducted underwater filming here.
03:53Their hard work will show us
03:56How do the Okavango River floods affect the ecosystem of the delta region?
04:01system
04:17This inland river in southern Africa originates in central Angola.
04:23It nourishes the land and sustains profound life.
04:34Every rainy season
04:35The Angra Highlands receive a lot of rainfall.
04:38Abundant rainfall will continuously gather along the terrain.
04:45They flowed down the hillside.
04:48Entering the dense river network
04:51Many rivers converge
04:53It eventually flowed into the Okavango River.
04:56Winding along the way
05:02The floodwaters in the Okavango River traveled more than a thousand kilometers.
05:06Finally, it flowed into the Okavango Delta and became part of the Hanjili life.
05:11dog
05:15In the perennial swamps of the Okavango Delta
05:18It is covered with lush paper grass and reeds.
05:31Drying equipment before the flood
05:33The river here is at its lowest water level.
05:38Aquatic plants release a type of compound when they decompose.
05:42That is, tannin
05:50This substance is widely found in plants.
05:53It even changed the color of the river water in some sections.
06:03Sudden flood
06:04It quickly engulfed the dense shrubs.
06:16As the waters transform
06:18The root system of the plant will become very developed.
06:26Thus below the root system
06:27It will form mysterious underwater caves.
06:37Many underwater caves were pitch black.
06:40Localized oxygen deficiency may even occur due to plant decomposition.
06:48But such a hidden world
06:49However, it is an ideal habitat for some organisms.
06:53This small New Year fish likes to prey on small shrimp.
06:56You can rub your body with your chest and knees.
06:58Makes a buzzing sound
07:14This kind of New Year fish in front of the camera
07:16Able to swim around with its abdomen facing upwards
07:19Using sensitive tentacles
07:21Searching for prey among the roots of the plant.
07:36Next to them
07:38The Dalian Kissing Rubber Fish uses plant roots to build tunnels
07:43and share with one of their close relatives.
07:50Both of these fish belong to the family Gumfishidae.
07:52Able to transmit through weak discharge
07:55To find prey in the dark
08:01They hide in open water at night
08:04But it will hide during the day.
08:06To avoid predators that are more powerful than them
08:16This is a strange creature that swims in underwater caves.
08:19Its body length can approach two meters.
08:31They are expert predators
08:52The jujube has long tentacles
08:55The jujube has long tentacles
08:55Able to sense even the faint electric current emitted by fish
09:00Once the prey is targeted
09:01It will be very difficult to escape.
09:06The annual meeting of the potted plant repeatedly collided among the roots of the plant.
09:10Drive small fish out of hiding places
09:17Tentacles were the main secret chamber tool of the year of the pot.
09:21Once the prey is spotted
09:23They will then launch a fierce attack.
09:25Devour the prey
09:41They were at the facility
09:42The shouts often made the river water murky.
10:03But even a year apart can have an end.
10:07That is Nero.
10:09The Nile, which can reach a length of six meters
10:11They will also come to underwater caves to find suitable places.
10:20The year of the elm was one of Neroe's favorite prey.
10:26Niroe's sensory organs are very sensitive
10:28Able to spot prey tens of meters away
10:35They also have an organ around their mouths that can sense water pressure.
10:39It can be used to determine the location of prey.
10:41Masa, who has no beauty output
10:52The goal is Nile
10:58Mabian people cross-Zen masters works
11:22Outside the underwater cave
11:23As the torrent passed by
11:25The river water gradually became clear.
11:30At this moment, the overflowing river water submerged the floodplain.
11:34Large numbers of fish were able to flow into deeper river channels.
11:48The village of striped dogs
11:50Swimming around near the water's surface
11:52Waiting for an opportunity is not the prey.
11:56The striped dog family possesses excellent speed and power.
11:59And strong riverbanks and sharp teeth
12:08They will attack almost any fish in the water.
12:11Launch an attack
12:20The striped dog will prey on small fish near the water's surface.
12:24If there is an opportunity
12:26They also hunt fresh fish
12:28They might even target baby crocodiles.
12:30Launch an attack
12:56Compared to Striped Dog Village
12:57The narrow-headed pufferfish adopted a completely different enclosed strategy.
13:02He is better at catching small fish by lurking and camouflage.
13:34Jonathan Lee
13:39The current carries more fish into the river.
13:42The feast on the water is still going on.
13:53The film crew followed the trail of the flood southwards.
13:59As the floodwaters left the damp highlands and flowed into the dry, flat Karaha...
14:04After the desert
14:05They will spread out in a fan shape.
14:08The Fjord Channel into the Okavango Delta
14:12The abundant water resources here provide an ideal ecological environment for flora and fauna.
14:17territory
14:18This is one of the most vibrant sections of the Okavango River.
14:25The surface of the swamp was covered with a curtain of water.
14:30Some African waters thrive here
14:43African waterfowl like to walk on aquatic plants such as sleeping curtains to forage.
14:49They practice one-stage multiple husbands
14:54This male African waterfowl is taking care of its unhatched babies all by itself.
15:01It will diligently care for its offspring.
15:10African water quality can make rapid progress overnight.
15:13Aquatic insects
15:15They have long legs
15:33Huge toes
15:35You can distribute your body weight over the night.
15:40But if they stay too long
15:41It will still sink overnight.
15:48Therefore, they must keep moving before sinking underwater overnight.
15:59At their feet
16:00It is a hidden world concealed by layers of curtains.
16:06This place is like a colorful underwater forest.
16:38YoYo Television Series X
16:57This is a peculiar plant.
16:59Aizao
17:02This herbaceous plant has long, creeping tendrils.
17:05With insect traps
17:07It is a small stone insect plant
17:14Insect traps of Lizao
17:16It can easily trap algae and other small organisms.
17:20Turn into a plant in a bag
17:31Li Zao's unique ability
17:33It helps control the number of problems solved.
17:35And the germs carried by mosquitoes
17:46In shallower river channels
17:48It was covered with a long stretch of sleeping grass.
17:53This small chainfish that makes a sizzling sound
17:56They often hide among the lush flowers and leaves.
17:58Avoid being spotted by prey or predators
18:07This is also a hunting ground frequented by the narrow-headed bream.
18:13Every few seconds
18:14A narrow-headed fish opened its big mouth.
18:16Like a vacuum cleaner
18:18Take a deep breath at the prey
18:31When a large number of aquatic plants die and rot
18:34It will severely deplete the oxygen in the water.
18:39Not every organism can survive in low-oxygen environments.
18:44Therefore, the striped dog will not swim here to hunt.
18:49This is for small fish that have entered the swamp due to the difficulty of moving them after the flood.
18:53In other words
18:53This is obviously a good thing.
18:55They hid among the dense curtains of light.
18:57Temporary safety can be obtained
19:01The striped dog's gift could only be given up because of the abundant food.
19:04But the hunting grounds lacked oxygen.
19:08But there is another kind of terrifying predator here.
19:12Perceiving Etiquette
19:18This freshwater fish is commonly known as the African rocket or diamond rocket.
19:22It is a large fish that can grow to tens of centimeters long.
19:27They may not be as fast or numerous as the thermostat dogs.
19:31But it also possesses unique secret room abilities.
19:49They can lie dormant silently for a long time.
19:53Patiently wait for the opportunity to attack
20:10Eventually the floodwaters slowly receded.
20:12Disappeared into the depths of the desert
20:21As the river channel becomes shallower
20:23Elephants began to carve out paths through the aquatic vegetation.
20:28Elephants come here to eat the tall, sturdy paper-shrinking grass.
20:33They will pack a large amount of paper straw
20:35They bite off pieces of food to obtain the nutrients they need.
20:38The destructive traces they left
20:46For the constantly flowing river water
20:47New waterways were opened up
20:56But the true deer-herding experts of the Okavango Delta
20:59It's a hippopotamus.
21:09Hippos are like heavy trucks
21:11Able to easily trample aquatic plants in the river
21:29At this stage, the hippopotamus calves are not yet able to move freely in the river.
21:34The mother's broad back became a safe island for them to stand on.
21:44Hippos often run on land and in water.
21:48This allowed a road to be carved out of the dense vegetation.
21:59These roads have formed a complex underwater transportation network.
22:19Even if the dense aquatic plants blocked the original river channel
22:23The newly opened path created by the hippopotamus still ensures the smooth passage of the floodwaters.
22:31When the flood comes
22:33The tricked river water will overflow onto the sandy land.
22:35And flowed along the terrain
22:37Inject into the dried-up low-lying areas
23:05It won't be long
23:06Han lands in the Okavango Delta
23:08It will turn into a swamp.
23:16This is especially true for wild animals adapted to arid environments.
23:20Not blaming is a disaster
23:24Only some animals were able to be moved to safety in time.
23:27Thus they escaped the sudden flood.
23:32This deer-shaped tortoise is lucky.
23:34After a long journey, it successfully reached the land.
23:47This area is usually extremely dry
23:50It is a habitat for some terrestrial organisms
23:57It is a habitat for some terrestrial organisms
24:19African lions don't really like going into the water.
24:22But they will not reject the benefits brought by the flood.
24:28The floods will attract many of Bosswana's wild animals to Africa.
24:33Lion's territory
24:35These animals need to find water sources to breed and forage.
24:38All of these will become prey targets for African lions.
24:48During such a dry season
24:49Elephants also need to fight for survival.
24:59Migrating elephant herds
25:00They often leave their families behind.
25:01They need to overcome numerous difficulties.
25:04After a long journey
25:06Only then can you reach the Okavango Delta
25:08Find sufficient water sources
25:17The arrival of the elephant herd
25:18It immediately aroused the interest of the African lion.
25:30Elephant calves
25:31They often become targets of attack by African lions.
25:38Therefore, during the search for water sources
25:40Adult elephants will try their best to keep their calves from straying too far from them.
25:54These elephants have been walking for months.
25:56The two machines went hungry along the way.
25:58They survived.
26:04The floodwaters flowing into the Okavango Delta at this time
26:07They were practically their lifeline.
26:36This may be the first time an elephant calf has seen so much water.
26:41A faint excitement in the water
26:43It made them forget the fatigue of the journey.
27:12The calf imitates the adult elephant
27:14Use a long brush to bring river water to your mouth
27:19An elephant's trunk is composed of approximately 150,000 muscle fibers.
27:23For cubs to use it freely
27:25It will take a long time
27:35The elephants began searching for food after crossing the river.
27:43In the swamps of the Okavango Delta
27:45It has lush meadows and dense Coca-Cola trees.
27:49But the elephants had to cross the riverbed.
27:51Only then can we get there.
27:58The river water almost submerged the elephant calf's body.
28:02If the cub accidentally falls
28:04They will likely drown.
28:21Adult elephants will protect their calves in the middle of the group.
28:25Help them wade through the water
28:27Because once you fall behind
28:29This means deadly danger.
28:44When the flood comes
28:45Nero will also seize the opportunity.
28:48Waiting for the best opportunity to hunt.
28:52A toddler elephant
28:54This would make it an ideal target for attack.
29:10But the herd remained around the calves.
29:12They built an insurmountable wall with elephant legs.
29:22finally
29:22The baby elephant successfully crossed the riverbank.
29:53But the danger is not over yet.
29:58The elephant herd entered the dense planting area.
30:18When the elephants are eating
30:20They will disperse without realizing it.
30:26For predators
30:27This is an ideal time to attack.
30:30Hungry African lion
30:32An operation was launched.
30:50African lion
30:51Using the reeds as cover
30:52An attack was launched
30:54This terrified the elephants.
30:56It began to descend into chaos
31:03In the scattering and fleeing
31:05The female elephant got separated from her calf.
31:11Xiao Yi, this allowed the elephants to buy...
31:25discuss
31:26In the scattering and fleeing
31:28Used for
31:28Oh, this allowed the elephants to buy...
31:31One road is one road
31:31for
31:31In the scattering and fleeing
31:32Xiao Yi, this allowed the elephants to buy...
31:43After the attack ended
31:45A baby elephant has gone missing.
32:06Xiangqun called in vain for the cubs to return.
32:11Until late at night
32:18Underwater, Nilee discovered a rather ideal secret chamber.
32:30Above the water's surface is a large, lush tree.
32:34The waterbirds were hit and built nests in different locations on the tree coffin.
32:54African slug jars occupy the upper part of the tree coffin.
33:04They would gather together when the flood passed through.
33:07Predating freshwater clams and shellfish on the riverbank.
33:17The yellow-beaked crown occupies the middle of the tree coffin.
33:26Near the bottom of the tree coffin
33:28These baby birds are begging their parents for food.
33:36The African tongue-tailed chicks seemed even more impatient.
33:40The African tongue-tailed chicks seemed even more impatient.
34:08Yellow mouth
34:10Tigerbird is an arduous task.
34:13Fortunately
34:13This large tree provides ideal foraging conditions for waterbirds.
34:20Water birds were seen falling continuously from the trees into the water.
34:23This attracted a large number of fish.
34:35Lu Ci and African snake body
34:37Of course, I wouldn't miss such an opportunity.
34:46Their feathers are not very waterproof.
34:48However, it can also reduce buoyancy.
34:50Therefore, they are all very good at diving.
34:59Nile also wanted a piece of the fish feast.
35:11It lies dormant quietly among the extensive root systems of trees.
35:15Waiting for the actual
35:19I think you might be using the extensive root system of trees.
35:21I think you might be using the extensive root system of trees.
35:30I think you might be using the extensive root system of trees.
35:50After Nero caught the fish
35:52It will make the fish head down
35:53Then I started swallowing.
35:55To avoid being slashed in the throat by a fish
36:20Nirohe will raise his mouth
36:22Throw the fish repeatedly to change direction
36:25After adjusting the prey to the optimal position
36:28Swallow it in one gulp
36:30I think you might be using the extensive root system of trees.
36:31I think you might be using the extensive root system of trees.
36:34I think you might be using the extensive root system of trees.
36:59Two weeks after the Zhou Shi attack
37:01A miracle occurred
37:05The missing elephant calf
37:07Survived
37:08And they returned to the elephant herd.
37:16But he still paid a heavy price.
37:19His tail was bitten off.
37:21There are very few physiognomy brushes left.
37:44Fortunately, the wound has now healed.
37:46His chances of survival also seem to have increased significantly.
37:54He can survive for the time being by drinking his mother's milk.
37:58Moreover, other relatives in the herd will also help him.
38:10This calf will not be able to live a normal life like other elephants.
38:14However, this severe injury is not yet fatal.
38:26When he comes of age
38:27Because there is no elephant pen
38:29He had great difficulty eating and drinking.
38:33His life or death will depend on the support of the elephant herd.
38:42He is growing up every day.
38:44Survival will become increasingly difficult
38:50But at least for now
38:51He was also able to receive meticulous care as a child.
38:54Live a carefree life
39:08As water levels gradually rise around the Okavango Delta
39:11The temperature also began to rise slowly.
39:19Here, vitality bursts forth once again.
39:30The flowers began to bloom with a fragrant aroma.
39:33It presents a magnificent scene of dazzling colors and unique patterns.
39:44Their nectar also attracted flying insects.
39:48After the temperature rises
39:49Dragonflies have received their breeding equipment.
39:57They mate in the air or on the ground.
40:00And lay their eggs in places with water.
40:07And the dragonfly's close relative, the damselfly
40:09It has a more complex mating ritual
40:16During mating
40:17Their bodies will form a heart shape.
40:21Male damselflies use the end of their abdomen
40:23Hold the female damselfly by the back of its head.
40:26clamp it
40:28Female damselflies will bend the end of their abdomen.
40:31clinging to the male damselfly
40:44After mating
40:46Female damselflies typically lay their eggs in water.
40:51Some even capture plant essences.
40:54Keep the body warm
40:56Briefly submerge your body in water
40:57To complete the egg entanglement
41:00underwater
41:01Their wings and even their entire bodies
41:04They all emit a crystal-clear light
41:12Female damselflies use ovipositors
41:14Injecting eggs into plant tissue
41:17Oxygen carried by female damselflies
41:19Enough to enable them to perform such underwater operations
41:29During this period
41:30Some male damselflies will continue to stay by the female damselfly's side.
41:34To ensure it lays eggs
41:36They will not be disturbed by other male damselflies.
41:41Before spawning
41:42Female damselflies can mate multiple times.
41:45Therefore, some male damselflies
41:47To ensure that their genes can be passed on
41:50Will protect your partner
42:01The damselfly's egg-laying ritual continues.
42:04Another animal nearby
42:05They also began to busy themselves with procreation.
42:17On the branches of trees in the swamp
42:19Pan frogs are mating
42:26The male Pan frog will continuously stir
42:28The mucus secreted by female Pan frogs
42:30Eventually forming foamy egg masses
42:34Not long after
42:35The tadpoles that emerge from the water will begin to forage for food in the water below.
43:04The mucus secreted by female Pan frogs
43:22After one night
43:23Many snowball-like foamy eggs appeared on the branches.
43:30New life is being nurtured there.
43:36After the tadpoles successfully hatch
43:37It will slowly drift to the bottom of the foam egg mass under the influence of gravity.
43:47When they grow to a certain size and are able to stand on their own
43:50They would fall into the water beneath the tree.
43:58By October
43:59The floodwaters have finally receded.
44:06The persistent high temperatures
44:08Let the water level in the swamp drop rapidly.
44:14As the water level in the shallows gradually decreased
44:17The fish schools are becoming increasingly dense.
44:37at this time
44:38On the outskirts of the Okavango Delta
44:41Water birds in the ever-shrinking pond
44:43Big and delicious fish
45:03Nero also joined the feast.
45:07Because the food is plentiful
45:09They do not disturb the water birds.
45:11Enjoying aquatic delicacies together
45:25The floods of this year are over.
45:28Spanning over a thousand kilometers
45:29Floods reaching the Okavango Delta
45:32It eventually disappeared into the desert.
45:37In the underwater world of the delta
45:39The battle for survival continues
45:43The perennial swamp located in the northern part of the delta
45:46Scope and narrowing
45:52The fish there are all concentrated in the main river channel.
45:57A large number of white deer took the opportunity to begin their predation.
46:24Besides the white deer
46:24The fish also face another dangerous predator.
46:28The Year of the Pot
46:41These ants launched repeated attacks on the shallows year after year.
46:44This caused the water surface to churn.
47:15The fish are all concentrated
47:16However, they also pay the price for their insane hunting.
47:20Their constantly writhing bodies often emerge above the water.
47:23This attracted the attention of the monkey eagle.
47:37Monkey eagles can spot and track underwater prey from very high vantage points.
47:53Once they lock onto their target, they will suddenly dive downwards.
47:56To precisely lift a fish weighing several kilograms from the water
48:42The arrival of the rain brought an end to this feast.
48:53The cold season is finally over.
49:18In the far north
49:20The rainwater in the Angra Highlands will once again converge into raging torrents.
49:32The flood is about to embark on another magnificent journey.
49:38The underwater world of the Okavango Delta
49:41Turning a new page in life
