snakes have inhabited this planet for the last 14000:08:05
million years how they managed to survive00:08:10

unlike others snakes that simply00:08:57
leave their eggs unattended the snake is00:09:00
constantly near them these snakes00:09:05
can lay up to 20 eggs at a time00:09:08
they will have to be on duty for about 50 days until the00:09:11
young hatch,00:09:20
however the snake cannot stay near00:09:23
them all day being cold-blooded00:09:27
creatures snakes do not have a mechanism for00:09:29
regulating body temperature they00:09:33
cannot lie without absorbing heat from the00:09:35
environment, the sun's rays give them00:09:53
energy to move, hunt and00:09:55
fight,00:10:00
the snake crawls on its belly,00:10:03
light is the force that determines all life in00:10:08
it, there is a short interval between light and00:10:18
darkness, birds of prey circle in the distance,00:10:22
it has a wide mouth and the famous kites00:10:25
bat hunters in the sky there is00:10:31
chaos and bats and wide mouth and their00:10:38
kites were waiting for darkness to hunt00:10:51
wide mouth and the kite rushes towards a00:10:53
flock of bats however due to the haste00:11:02
he00:11:10
misses the target he fails despite the fact that it00:11:12
would not be swarming bats00:11:27
finally manages to grab the prey00:11:34
such a scene is repeated daily like00:11:37
light and darkness00:11:38
life and death barely separated by a very00:11:42
thin line00:11:58
in the darkness the babies begin to hatch00:12:01

a breath it seems they will have to wait for the light00:12:28
for an eternity00:12:30
[music] you00:12:39
need to be careful walking through a dense00:12:41
forest high in the mountains00:12:51
here the eastern cottonmouth is basking this00:12:57
snake perceives the surrounding world through00:13:00
smell and temperature it sniffs with its tongue00:13:05
night snakes have elongated vertical00:13:08
pupils like cats00:13:16
through this depression the snake00:13:18
feels warmth if a snake rattles its tail,00:13:25
it is wary, it immediately00:13:31
shrinks upon seeing the prey at this very00:13:38
moment, the snake is especially dangerous00:13:40

rapid attack00:13:51

eastern copperhead is also called a 7-00:14:01

strong venom of which it immobilizes the00:14:06
bitten victim after seven steps,00:14:10
however, if it is not provoke this snake00:14:13
avoids humans the00:14:26
eastern copperhead produces00:14:29
offspring in mid-August, unlike the snake's00:14:35
cubs, the00:14:36
young of this snake are covered with a thin00:14:38
shell the eastern copperhead and the eggs are00:14:48
viviparous the young hatch inside the00:14:53
mother's body remaining in the womb they00:14:55
feed on egg yolk the00:15:08
mother snake usually gives birth to d10 young at a time00:15:10
this snake also they call the00:15:18
mother snake a killer and for the belief that the00:15:21
cubs eat their mother from the inside, the baby00:15:30
snakes are born poisonous, the00:15:40
newborns are in no hurry to leave the mother,00:15:46
this behavior looks like they are00:15:49
trying to kill her, which gave rise to00:15:51
the nickname of this snake, perhaps this belief00:15:58
arose due to the fear of their strong00:16:00
poison, the newborns dried out snakes00:16:08
crawl away to lead an independent00:16:11
life00:16:32
at this time of year there is a lot of food00:16:37
our snakes have grown up to 15 centimeters in00:16:40
length00:16:42
armed with a powerful I will give them they are not00:16:45
afraid of anything at this time they must eat well00:16:50
to prepare00:16:52
for the coming winter00:17:12
many young snakes will not survive this00:17:15
season00:17:21

only the strongest will remain they will00:17:27
dominate00:17:29

the snake instantly bites with its poisonous00:17:46
fangs there are about 3000 species of snakes in the world00:17:53
but only 50 are armed with00:17:55
deadly poison cobra the queen of poisonous00:18:07
snakes00:18:10
the pattern on its back resembles eyes and00:18:13
this is a warning sign for00:18:15
uninvited guests00:18:16
when she is threatened or excited,00:18:19
she reaches up and opens her00:18:21
hood00:18:24

collar and you cobra is famous for00:18:36
spitting out the fly, it splashes out of her00:18:40
poisonous fangs00:18:42
[music]00:18:46
and [music]00:18:55
the head of the snake repeats the movement of the victim00:18:59
and then splashes I will give it in her eyes00:19:02
[music]00:19:10
it almost never misses and it is00:19:14
strong enough to make the victim blind00:19:21
spray its poison this defense00:19:24
they attack snakes do this because00:19:35
only the most developed species of snakes are afraid; they00:19:38
have poison the00:19:42
snake stretches out one third of the length of00:19:45
its body to spray I'll give it 3 -400:19:47
meters forward with a00:20:04
snake there are no competitors in terms of shooting00:20:07
at long distances00:20:12
not many other animals can00:20:15
carry out an attack from afar from such00:20:17
a position this makes the cobra an adversary00:20:20
that cannot be ignored00:20:44
life of infinity is also difficult to00:20:46
imagine as a life dependent on00:20:48
fins00:21:18
silent air full of tension00:21:20
between the victim and as a predator, the moment of truth00:21:27
comes in a matter of seconds,00:21:42
it is impossible to say who will soon gain an00:21:44
advantage, but if you watch00:21:49
longer, everything will become clear, the00:22:01
strongest wins because he00:22:03
never gives up,00:22:28
this snake moves freely through the water,00:22:31
despite the fact that it has no fins,00:22:38
this is an Asian fisherman, his favorite00:22:46
prey frogs00:22:59
snakes live in any environment00:23:01
except the coldest regions of the world00:23:09
this water snake is usually found in00:23:12
korea00:23:21
water it controls its body as00:23:24
if it has fins it00:23:28
moves forward in a zigzag fashion00:23:42
water snakes live near rivers feeding on00:23:45
frogs and freshwater fish00:24:01
life reptiles that you have to00:24:03
compete with the fish in the water is quite00:24:05
difficult,00:24:15
only one out of 10 attempts is successful00:24:21
[music]00:24:24
water snakes are not poisonous they must00:24:29
squeeze tightly 3 trying fish00:24:47
[music]00:24:49
when the fish begins to lose strength the snake00:24:52
squeeze it even tighter00:24:56
[music] the00:24:59
hunting method is the same both on land and in00:25:02
water, snakes00:25:06
use a long body; eating is00:25:17
as difficult as hunting;00:25:29
to swallow a fish, a snake takes about00:25:31
half an hour; the battle between a snake and a fish is00:25:36
nearing its end;00:25:51
can you remember how many species of animals00:25:53
thrive both on land and in water; a00:25:58
snake is one of the few00:26:04
well on the ground without any00:26:07
limbs and she swims in the water without00:26:10
fins00:26:20
in the depths of hot humid rain forests00:26:25
snakes live in dark swamps a rare00:26:40
fisherman will live where it is so dark where00:26:43
almost nothing is visible the long body00:26:52
makes ripples in the water the color of the snake00:27:07
is pale brown on its the head has two00:27:14
tentacles similar to horns, hence00:27:18
the name tentacled snake,00:27:25
it spends most of the time in the water00:27:27
abc troops you are around the algae00:27:34
every half hour the snake floats to the00:27:36
surface of the water these snakes live under00:27:42
water but breathe through their lungs and are forced to00:27:45
rise and inhale air from time to time the00:27:54
tentacles on the head allow them00:27:57
to determine the direction of the current00:28:03
[music]00:28:13
where the00:28:14
tentacled snake is a good hunter00:28:17
[music] the00:28:30
fish very quickly changes direction one00:28:36
step away from being caught it00:28:38
turns sharply00:28:47
this is00:28:52
its way of getting away from enemies a00:28:56
defense mechanism that the fish uses00:28:58
when it catches a sudden movement in water00:29:01
[music]00:29:07
this is called with the start from the figure when the00:29:11
fish turns its body00:29:14
[music]00:29:17
this is a reflex movement caused by00:29:20
the athlete past the untera that are present00:29:22
in fish nt00:29:25
[music]00:29:31
[music]00:29:37
tentacle nose on I snake curls its body00:29:40
in a loop and patiently waits for the fish00:29:45
[music]00:29:50
but every attempt fails due to the00:29:54
instantaneous reflexes of the fish; the fish00:29:58
needs five00:30:00
thousandths of a second to turn around, and the snake00:30:04
requires 15 thousand to throw; the fish moves 300:30:09
times faster; simple mathematics says00:30:14
that the snake has no chance, but quite00:30:19
often it manages to succeed;00:30:25
how does this happen?00:30:31
watch closely the tentacled snake and the fish00:30:37
[music]00:30:40
the snake moves by anticipating the direction the00:30:43
fish will move this strategy00:30:52
using the long body of the snake creates ripples00:30:55
causing the fish to00:30:56
turn around by spark logic however00:30:59
the turn brings the fish right into the mouth of the00:31:02
snake the00:31:03
rivers are created to attract the fish there the00:31:18
fish turns around cannot change00:31:20
direction such is the power of instinct the00:31:23
tentacled snake uses this00:31:26
instinct to overcome the00:31:28
speed lag00:31:29
[music]00:31:34
these are the strategies with the tentacled snake00:31:36
to thrive underwater without having00:31:39
fornicators00:31:59
here the sun rises higher than anywhere00:32:02
else in the world00:32:05
two and a half thousand millimeters of00:32:07
precipitation falls here every year00:32:08
high temperature and humidity00:32:09
allows trees to grow up to 40-60 meters00:32:21
in the jungle the most diverse flora and00:32:25
fauna00:32:28
life is in abundance here as there is a00:32:31
severe struggle for survival00:32:34
[music]00:32:39
weapons of this lizard color like a00:32:46
chameleon light changes depending on the00:32:48
intensity of light temperature and00:32:50
mood this is a lizard fiercely guards00:32:55
its territory in these rain forests00:33:01
you need to look not only at your feet but also00:33:03
up00:33:10
this snake spends the most time00:33:13
in the trees if it had00:33:20
limbs it would not think of leaving the00:33:23
ground this specimen with an upturned00:33:37
nose is another type of tree snakes snakes00:33:46
can live high in the trees because00:33:48
in the process of evolution they lost their legs in exchange00:33:51
for body length life without legs the whole body of the00:34:04
snake, like an arrow, the head must find the target00:34:15
and the long body will follow it all00:34:30
other difficult moments are forgotten,00:34:32
only the body of the snake rushes forward,00:34:38
sensing the smell of prey, a shiny tree00:34:48
snake eats tree lizards,00:34:50
frogs and bird eggs00:34:55
sometimes your diet completely determines00:34:59
your lifestyle this frog00:35:05
spends its entire life in the trees00:35:07
except for the period when it mates00:35:09
and spawns00:35:12

this is a flying frog it uses00:35:39
wide webbed feet like wings00:35:43
this frog had to learn to fly00:35:45
to survive she learned to swim and00:35:50
jump but that was not enough00:35:53
[music]00:36:13
[music]00:36:29
the frog is only 15 centimeters long but00:36:32
can fly 15 meters00:36:34
which is 150 times the length of its body00:36:40
imagine what people need it would be00:36:42
to use your legs to fly and you will understand00:36:45
some great feat, something in this00:36:53
jungle made the frog fly, the00:37:07
movement of paprika, the laws of gravity,00:37:10
it has more than 400 ribs and it moves00:37:13
wherever it wants, high above the ground,00:37:22
here someone is hiding and perfectly00:37:31
camouflaged, the main prey of caloto00:37:39
insects living in trees, such as00:37:42
ants, a snake approaches the target quietly and00:37:49
inevitably, a lizard jumps in the air, a snake00:38:10
follows him00:38:13
[music]00:38:29
flight is a sure way to survive in the air00:38:34
[music] a00:38:40
flying geek, he learned to fly to00:38:43
hunt or to escape from00:38:45
predators, it is not known exactly why, but this is a00:38:49
lizard can use its legs as00:38:52
wings00:38:58
[music]00:39:13
it is only 20 centimeters long00:39:20
but can cover a distance of 20 meters00:39:27
draco smotra us uses for flight an00:39:30
unusual part of the body under the limbs00:39:41
along the chest it has well-00:39:43
developed flight membranes the lizard00:39:50
throws its body up and opens the00:39:53
membranes like wings00:40:02
and lizards fly through the air a rich00:40:11
ecosystem00:40:12
means a fierce struggle for survival00:40:15
[music]00:40:29
snakes devote their entire lives to this fight the00:40:33
lizard merges with the surrounding00:40:38
landscape00:40:54
[music] the00:41:04
paradise decorated snake squeezes its00:41:07
prey like other non-venomous snakes00:41:10
and also paralyzes the weak The00:41:16
problem with this snake is that its prey00:41:20
lives high above the ground. The snake that00:41:31
decided to live in the trees must00:41:33
solve important problems every day. Firstly,00:41:39
it is difficult to transfer its body from branch to00:41:41
branch. The problem is aggravated if there is00:41:51
too much distance between the trees. The00:42:03
paradise decorated snake has chosen flight for itself.00:42:06
she jumps through the air using her00:42:13
body as a spring while00:42:23
descending she bends her body into the shape of the00:42:26
English letter s while00:42:27
floating through the air she twists her body from00:42:30
side to side to maintain00:42:32
balance00:42:38
she mixes with a branch on her tail00:42:41
pulls her body back00:42:43
and then rushes forward00:42:47
100:42:58
[music]00:43:01
there are five types of fliers a snake and this is the00:43:06
best flyer of all,00:43:27
how did she learn to fly despite the00:43:30
obvious lack of wings, it’s a mystery she00:43:39
opens her chest like a parachute and00:43:41
presses her back to her stomach, the main thing is00:43:47
to increase the lifting force and reduce the00:43:49
drag by spreading out the usually round00:43:51
body00:43:55
[music] after00:44:22
observing many snakes we00:44:25
discovered that a flying snake begins its00:44:27
flight falling at an acute angle of 62 degrees00:44:31
but maintains an angle of 13 degrees with00:44:33
its body spread out and can cover a00:44:36
long distance in flight00:44:38
[music]00:44:45
having a body one meter long it can00:44:48
fly through the air up to 100 meters00:44:56
although it is safer to remain on the ground00:44:58
flight gave to her the speed and freedom of00:45:01
flight of a bird00:45:05
[music] a00:45:20
snake is the only animal capable of00:45:23
flying infinity or wings, it is still00:45:31
unknown exactly why snakes began00:45:34
to fly, we can only imagine the00:45:40
terrible circumstances that00:45:42
eventually forced snakes to fly without wings00:45:58
[music]00:46:03
time from sunset to dawn for00:46:05
some animals00:46:06
means the period between cold and warmth00:46:11
[music]00:46:14
warmth spreads to all living00:46:16
creatures on earth,00:46:17

earth and its nature have evolved over00:47:23
billions of years00:47:27
[music]00:47:34
it was in the initial stages of its00:47:36
development that our planet was uninhabitable00:47:38
due to the high00:47:40
surface temperature it took millions of years00:47:43
for the earth to cool down and become hospitable00:47:46
for life the first living organisms were00:47:51
primitive coincidence and00:47:55
the laws of evolution led to the emergence of00:47:57
many different species00:48:01
[music]00:48:09
all living things strive to reproduce if a00:48:14
species manages to adapt to its00:48:15
environment it will leave large offspring00:48:33

survive relying only on themselves all00:48:41
animals in the food chain depend on each00:48:43

bells evolution has given animals a very00:49:00
effective strategy for using I yes00:49:06
I am a very effective way to kill prey00:49:10
but producing poison is not easy00:49:12
[music]00:49:32
well they say for animals that use poison00:49:35
do not resort to it of their own free will,00:49:38
nature created them poisonous00:49:45
Episode 1 poison and survival strategy00:50:00
ghost section of the old man is located in00:50:03
central America00:50:07
with the invaluable asset of this small00:50:10
country being virgin tropical00:50:13
forests00:50:14
[music]00:50:16
aldar horse of Costa Rica half the00:50:18
area of South Korea00:50:20
but diverse species of flora and00:50:22
There is more fauna here than on the entire African00:50:25
continent;00:50:36
abundant rainfall is beneficial for both the earth00:50:39
and animals;00:50:41
thanks to frequent rains,00:50:44
beautiful dense00:50:45
healthy jungles grow;00:50:51
hot and humid climate; the00:50:53
Costa Rican jungle; an00:50:54
ideal habitat for amphibians;00:50:56
for example, for this frog, there00:51:02
are no membranes on its legs; the humidity level is00:51:05
so it is high that frogs survive even00:51:08
without water, this species lives mainly in00:51:13
trees to make climbing trees00:51:15
convenient; nature has endowed these frogs with00:51:18
long hind limbs. The00:51:20
red-eyed tree frog is often found in00:51:23
Costa Rica; it has spherical red00:51:26
eyes00:51:30
up to the cheekbones; and this glass frog has a00:51:32
transparent skin,00:51:36
a little green the back blends in with the foliage00:51:39
but the skin on the belly they have pigment and00:51:43
you can see how the00:51:48
frog's heart beats the prey of many animals it seems the00:51:51
unique skin of the glass frog00:51:53
allows it to remain invisible to00:51:56
predators the diffused sunlight itself00:52:01
barely reaches the ground through the dense00:52:03
foliage all around there are00:52:07
bright green leaves00:52:23
[music ]00:52:25
small poison dart frogs00:52:27
interesting outfit blue jeans and a red00:52:30
hoodie and the red body is00:52:34
clearly visible against the background of green foliage in00:52:38
Costa Rica and that’s what they call the frog in00:52:40
blue jeans00:52:41
why it has such a bright and noticeable00:52:43
color in the jungle predators are found at00:52:51
every turn after all, you are they are constantly looking for00:52:54
easy prey the best survival strategy is00:53:03
to use protective coloring00:53:06
[music]00:53:17
red frogs are very small00:53:20
but they are easy to spot00:53:26
well, most frogs have a protective00:53:29
coloring that saves them from predators despite the00:53:46
noticeable coloring the small poison dart frog00:53:49
fearlessly crawls through the jungle and00:53:52
even exposes itself for show00:53:54
attracting attention this is why this00:54:00
frog is so bright00:54:07
[music]00:54:21
and dreams of how the snake appeared a mortally00:54:27
dangerous enemy00:54:29
[music] the00:54:34
little poison dart frog is not aware of the00:54:37
danger00:54:45
dodge the hunt has begun the00:54:50
snake has descended in pursuit00:54:52
the frog does not suspect anything00:55:00
Egor Moskal available does not seem to be prey00:55:03
the hunter invests in the chase00:55:18
found all the strength the snake resumes the chase scarlet00:55:32
varnish00:55:33
fortunately the frog is still alive but the hunter00:55:38
appears again00:55:44
[music]00:56:14
[music]00:56:26
if the little poison dart frog is about to00:56:29
die capture the prey the snake is trying to00:56:32
swallow his lunch00:56:35
[music]00:56:48
but why did the snake burp and the frog the00:56:51
little poison dart frog is running away00:56:57
what happens to the snake it writhes in00:57:00
pain00:57:05
[music]00:57:10
audits00:57:11
why the frog survived by looking at the00:57:15
frog the snake turns around and leaves the00:57:18
battlefield what the poison dart frog did00:57:23
with us when the snake bit the frog00:57:27
before rushing into a counterattack he00:57:34
took out a small poison dart frog produces00:57:38
toxic substances00:57:39
when he is attacked he secretes poison00:57:42
through pores on the skin so that the predator00:57:44
would spit it out, who won the little00:57:51
poison dart frog00:57:59
on the radio, and not quite biting the frog,00:58:06
the snake struck such a force that the00:58:08
poison dart frog died in a few minutes, why is the poison00:58:12
dart frog working out, I’m ready, the00:58:22
death of one little poison dart frog is a00:58:25
sacrifice that will save the rest of us00:58:31
from now on,00:58:32
snakes and other predators know that the00:58:35
small one has 3 hairs and crushes and cannot be00:58:38
eaten00:58:39
[music]00:58:46
the author, having tried with one small00:58:48
poison dart frog, the snake will not encroach on others,00:58:52
so the life of the poison dart frog will be calmer00:58:59
[music]00:59:04
now red frogs have a better chance00:59:07
of surviving in the jungle00:59:09
the ability to accumulate toxins00:59:11
dark in nature endowed the little ones00:59:14
with his holes how does this frog00:59:17
produce poison it gets it from food00:59:24
most plants are poisonous to one00:59:27
degree or another sams some small00:59:30
insects in costa rica can accumulate00:59:33
alkaloids in their bodies that they00:59:35
get from plants00:59:38
for example termites00:59:40
and some beetles00:59:42
[music]00:59:57
squirrel In the frog's body,01:00:00
alkaloids eaten by insects are converted into01:00:03
poison which is stored in special glands on the01:00:12
fox when the frog is attacked it01:00:14
releases the poison through its skin rain and launches a01:00:17
potentially lethal counterattack but01:00:23
this survival strategy is not easy,01:00:28
unlike other frogs the01:00:29
small poison dart frog is small instead of the01:00:33
intimidating size it uses poison01:00:39
[music]01:00:42
why is this male inflating the resonator01:00:45
to attract a female01:00:47
instincts tell the frogs to mate and01:00:50
pass on their01:01:04
cycle genes Rodrigo Lazov found a secluded place01:01:07
inside the bromeliad01:01:08
here the female will lay eggs in the humid01:01:19
jungle of Costa Rica01:01:20
frogs usually lay eggs on the01:01:23
leaves but when the female will lay the01:01:28
eggs the male will fertilize them, this is where the01:01:32
parents' worries end01:01:34
[music]01:01:43
predators take advantage of this to snack on01:01:46
eggs in the jungle frogs lay01:01:49
millions of eggs01:01:50
so that some of them will survive01:01:54
[music]01:01:56
in the jungle it rains a lot, every01:02:03
rain is a new beginning tadpoles hang from the01:02:07
leaves and jump to the ground01:02:10
[music]01:02:16
we tear off other animals are ready to snack on them01:02:19
therefore weak and defenseless01:02:24
species lay a lot of eggs in the hope01:02:28
that at least someone will survive the01:02:34
bromeliad leaves form a cup in the middle01:02:36
which accumulates a little water an01:02:40
ideal place for mating small01:02:43
poison dart frogs do not take poisons01:02:51
along with food and therefore grow very01:02:54
small and can lay only three01:02:56
or four eggs; the eggs remain01:03:01
under the protection of the male; he makes sure that01:03:04
they are not eaten by a spider or another male01:03:07
poison dart frog; the tadpole hatched from the01:03:17
eggs; more protection is needed; it whined as soon as the01:03:34
tadpoles hatched; the male gives a01:03:37
signal to the female; now guardianship falls on the01:03:40
female01:03:44
she carries a tadpole on her back needs to01:03:47
find a safe place for it the female does not01:03:58
pay attention to the usual food01:04:00
she must climb a tree with the baby01:04:03
on her back01:04:05
[music]01:04:15
bought mother calm down when she carries01:04:18
the tadpole to the bar amelia hanging on the01:04:20
tree but there is no food here so the01:04:25
female lays unfertilized01:04:27
eggs this is food for the tadpole01:04:34
[music] having01:04:42
safely delivered the tadpole the female01:04:44
does not rest below waiting for other01:04:47
tadpoles to raise as01:04:51
many offspring as possible you need to hurry01:04:56
[music] the01:05:15
inhabitants of the jungle do not sit still01:05:18
hot and humid climate01:05:21
ideal living conditions tadpoles01:05:27
hatched 2 months ago they have already01:05:30
grown up and turned red like their parents, the01:05:33
baby frogs remember which way their mother01:05:35
climbed the tree with them and bravely01:05:38
jump from leaf to leaf01:05:45
[music]01:06:13
in a dream a snake basks in the sun;01:06:21
in the jungle, red means01:06:24
poison, so the snake does not risk attacking the01:06:28
frog by cheating the frog shows no01:06:31
interest in each other two for the snow01:06:43
then why is the snake chasing the frog this01:06:47
young frog follows the instinct01:06:49
that tells him to eat eat termites from the01:06:52
areas of their poison suddenly the snake descends01:06:57
in careful pursuit01:07:18
the frog sees the snake01:07:20
but is not afraid however the snake chases01:07:27
the frog as if it does01:07:29
not miss prey out of sight01:07:35
[music]01:07:44
[music]01:07:58
[music] the01:08:08
snake makes a risky decision01:08:10
to attack, but the poison of the frog should01:08:13
paralyze the snake, it will not be able to01:08:16
swallow prey01:08:23
[music]01:08:25
this snake does not regurgitate the frog01:08:28
swallows the poison has no effect on the predator01:08:34
in the duration of this snake is aborigines01:08:37
Costa Rican stigma do his has developed01:08:40
resistance to poison dart frog is a01:08:44
natural enemy01:08:49
[music]01:08:52
inicio in nature it is not the strongest that survives01:08:55
ok the one who has adapted better the little01:08:59
poison dart frog chose poison as a means of survival01:09:05
[music]01:09:10
how else can a frog protect itself from01:09:12
natural enemies and this species will continue01:09:15
their existence01:09:18
[music] the01:09:35
first living organisms were simple01:09:38
bacteria jellyfish appeared 600 million01:09:44
years ago the01:09:45
first multicellular organisms on the01:09:48
planet01:09:50
[music]01:10:10
amanda there are more than 200 species of jellyfish01:10:14
but only the box jellyfish can swim straight01:10:17
towards its prey jellyfish drift in the ocean01:10:23
at the will of underwater currents01:10:27
the seas are unpredictable but jellyfish01:10:31
have changed little over the past 600 million01:10:33
years, this simple organism lives on earth01:10:39
longer than most species01:10:50
with corals and sea anemones being the same age as01:10:54
jellyfish and they all belong to the01:10:57
coelenterates, they are one of the01:11:01
first inhabitants of the sea01:11:04
[music]01:11:09
do not throw out stinging threads01:11:14
[ music]01:11:19
we don't know when they got this01:11:21
ability but apparently it played an01:11:24
important role in the fact that they survived01:11:26
hundreds of millions of years you would think that01:11:31
not a single fish would come close to a poisonous01:11:33
coral but among them there are many different01:11:36
species in coral reefs there is a lot of food01:11:42
sea anemones are called sea01:11:45
flowers for hunting they use01:11:47
tentacles at the end of the tentacles are out of the question01:11:51
due to high toxicity these01:11:53
organs have very bright colors01:11:57
[music]01:12:00
nudibranchs have01:12:02
bright bodies they cannot survive without comment01:12:06
[music]01:12:10
some nudibranchs themselves feed on01:12:13
hydra my and corals Once in danger, they01:12:16
protect themselves with the poison of the eaten sleep,01:12:19
they do not have a hard shell with01:12:22
undeveloped muscles, but they have poison; in addition, the01:12:27
bright color means poisonousness01:12:30
and should scare away enemies01:12:33
[music]01:12:38
max down, the box jellyfish resembles a cube01:12:42
[music]01:12:44
it has a rather complex structure, it01:12:48
feels the difference between darkness and01:12:50
light and can swim towards its01:12:53
prey, but the main thing is what the01:13:00
box jellyfish is famous for, the poison it stings is very01:13:03
painful, why it is01:13:04
called a sea wasp, how does a01:13:08
box jellyfish produce such a strong poison01:13:13
with the help of poison, a jellyfish kills fish, a01:13:17
box jellyfish swims faster than many01:13:19
cons, but still not can catch up with01:13:22
the fish, so it waits until the current01:13:28
brings the fish closer, finally the fish01:13:33
has approached, you have touched the01:13:40
fish with tentacles, time is very important01:13:45
[music]01:14:08
these two seconds and the fish is amazed, it seems01:14:12
it is paralyzed but the hunt is not01:14:18
over yet, consciousness will return to the fish and it01:14:21
will fight01:14:25
[music ]01:14:27
hunting for fast and strong fish is01:14:31
not an easy task, the predator must be prepared for unexpected01:14:34
situations01:14:37
at the end of the tentacles of the jellyfish are due to01:14:40
lack of sleep, the01:14:41
hollow organs of the nematocysts are located in them01:14:43
and they rupture and a01:14:46
thread is released01:14:48
that will pierce the skin and inject poison into the01:14:51
nematocysts they produce poison he numbers01:15:02
would entangled in the tentacles and her fate is01:15:04
decided, she will stop fighting and the jellyfish01:15:08
and will eat for this the jellyfish will wait for01:15:12
the tentacles so she pushes the fish01:15:16
closer to her the box jellyfish is adapted01:15:21
to hunting better than many jellyfish but its01:15:24
digestive system is the same01:15:26
as the others the same hole01:15:28
is used both for eating and for removing the01:15:31
remnants of eaten food01:15:33
[music]01:15:42
the body of a jellyfish consists of gelatinous tissue,01:15:47
it easily tears at the slightest01:15:49
touch,01:15:54
some fish themselves, if they hit a jellyfish,01:15:58
they can tear it in half01:16:02
[music]01:16:06
the weapon of a jellyfish is its poison01:16:09
[music]01:16:12
maximum, with its poison01:16:14
it can not hit only fish it is01:16:17
fatal to humans from the point of view of the01:16:19
evolution of fish and people are close01:16:22
relatives of both fish and people are01:16:25
vertebrates01:16:31
[music] the01:16:32
poison of a box jellyfish brings death to vertebrates01:16:38
therefore people are01:16:40
evolutionary relatives of fish can01:16:42
suffer from this poison01:16:48
[music]01:16:50
zombies some experts consider01:16:52
jellyfish more dangerous sharks, most jellyfish01:16:56
drift in the ocean at the behest of underwater01:16:58
currents, instinct tells them to use01:17:02
poison, so you can’t blame them01:17:10
[music]01:17:16
weight be this reef01:17:18
looks very peaceful, but there are01:17:21
fierce battles using01:17:23
biochemical weapons,01:17:24
many inhabitants use poison01:17:28
[music] there are01:17:32
many left in the depths of the ocean01:17:35
unsolved secrets how much new we01:17:38
will learn about the life of the seas in the coming years01:17:43
[music]01:17:50
the modes of evolution in the harsh ocean are much01:17:54
more diverse than on land01:17:58
[music]01:18:06
my life originated in the ocean and from there01:18:10
came to land various land animals began to develop,01:18:15
but one animal01:18:18
returned to the sea01:18:38
001:18:41
elizabeth sea snake01:18:44
[music]01:18:47
many millions of years ago some snakes01:18:50
returned to the ocean mura why did this01:18:55
happen why snakes decided to live in the sea01:18:59
it is unknown01:19:01
[music]01:19:11
or a sea snake swims beautifully and01:19:14
feels great in the sea it’s01:19:17
amazing that once it was a01:19:19
terrestrial creature01:19:21
[music]01:19:32
coffee over millions of years the snake has adapted01:19:36
to life under water it has smoother01:19:42
skin than those living on land01:19:44
to make it easier to swim it01:19:50
crawls easily along the bottom the01:19:52
snake’s tail resembles a fin to make it01:19:55
easier to move under water and01:19:59
[music]01:20:00
basic but a sea snake must01:20:02
rise to the surface because01:20:05
it breathes with lungs, they use gills01:20:13
and topsy, it takes in air and01:20:17
goes back under the water, the snake does not stay on the01:20:20
surface because of the birds, however, it must01:20:23
surface every hour and during hunting it01:20:27
needs air every 20 minutes01:20:33
[ music]01:20:37
prey not visible fish are the main01:20:42
food of snakes their venom is close to that of a cobra but is01:20:45
more toxic01:20:47
this may mean that hunting01:20:50
underwater is more difficult than on land01:20:58
for reasons unknown to us sea snakes01:21:01
now live in the ocean perhaps they01:21:04
made the wrong choice01:21:05
but in evolution there are no right ones and wrong01:21:08
decisions01:21:18
[music]01:21:21
bear earthly life originated in the ocean,01:21:25
the planet is inhabited by many different01:21:27
species that have developed unique survival strategies01:21:31
[music]01:21:45
[music]01:21:56
itself, some species have multiplied, others01:21:59
have become extinct,01:22:05
but if a species exists today,01:22:08
this does not mean that it will exist, a01:22:10
new one can always appear a rival01:22:13
or the habitat changes dramatically,01:22:15
then the animals will have to adapt01:22:18
again account predator snail consul and01:22:31
moves slowly,01:22:32
it is voracious and can eat fish01:22:35
the size of itself01:22:37
[music]01:22:45
but how can it hunt fish01:22:48
if it moves so slowly, it01:22:54
draws in water through a long trunk and01:22:56
sniffs out prey01:22:58
this part of the body is the eyes of a snail it can01:23:02
catch light the snail cannot catch up with01:23:09
prey so it waits for sunset one night01:23:19
the ocean looks completely different than during the day01:23:23
not a single fish is visible it is resting01:23:27
its state is close to sleepy the fish is very01:23:31
lethargic the01:23:38
prey is approaching01:23:39
this and the snail is waiting cone this proboscis01:23:44
sensor which sticky determines01:23:46
the location of the prey, a01:23:50
large pipe appears from the snail's mouth01:23:53
to find the fish by smell01:24:05
missed but what is it this is the01:24:16
radula of the01:24:18
snail there is a radula similar to a spear where the01:24:21

more suitable for mammals than01:28:39
for reptiles,01:28:40
however, crocodiles need much less01:28:43
food than lions, so they were able to survive01:28:46
in Australia01:28:47

Яд и стратегия выживания На протяжении веков змеи представлялись как зловещие животные в человеческой психике. Однако в этом шоу змеи демонстрируют свою изобретательную адаптацию к жизни на земле. Среди всех видов животных только змеи обладают способностью выживать на суше, в море и даже летать в воздухе. Шоу начинается со сцены, в которой ленточные змеи сотнями и тысячами, размножаются после пробуждения от зимней спячки в Канаде. Показаны также жизненные циклы корейских крысоловов и гадюк. И секрет того, как летающие змеи могут летать, показан путем отслеживания и изучения райской украшенной летающей змеи и обыкновенной украшенной летающей змеи, которые живут в джунглях Азии. Мало того, что документальные экипажи запечатлели полет летающих видов змей, они также сняли яркие сцены с летающими лягушками и летающими ящерицами в процессе полета. Впервые зрители смогут увидеть, как щупальценосная змея охотится на рыбу в замедлении, снятом с использованием высокоскоростных камер. Эта программа разрушит многие распространенные убеждения людей. Существуют различные факторы, которые влияют на эволюцию жизни на Земле: изменение окружающей среды, паразиты, питание, естественные враги, климат и многие другие бесчисленные факторы. Среди многих эволюционных качеств, которые развили животные и растения, способность производить яд весьма необычна. Съёмочная группа посетила пустыни, тропические леса и дно океана в поисках ядовитых животных. Какие яды они используют? Как яд коррелирует с естественным отбором? Какую роль играет яд в эволюции? Эти вопросы обсуждаются в этом документальном фильме. Коста-Рика расположена в Центральной Америке, где вы найдете клубничную ядовитую лягушку-древолаза. Несмотря на то, что она маленькая и уязвимая, она демонстрирует яркие цвета, которые делают её выделяющейся в лесу, в отличие от других животных, которые используют камуфляж для сливания с окружающей средой. Почему это так? Потому, что у клубничной ядовитой лягушки-древолаза смертельный яд. Как они развили такой яд?
