00:00If you had already known a bad day at work,
00:03remember that it would have been worse.
00:06You have, at least, not been happed by a baleine of 40 tons.
00:10You have not stayed 30 seconds in a living being,
00:13to think that your end was coming.
00:16Contrairement to the protagonist of this story,
00:18a plonger of homard is becoming a involuntary of a baleine.
00:24Fortunately, a baleine can't really avate a human.
00:28Not because we would be eatable,
00:30but because it is anatomically impossible.
00:33Even if this animal can reach a colossal dimension,
00:36its gorge is extremely close,
00:39barely comparable to the diameter of an ordinary pamplemousse.
00:43Their open mouth can reach a small piece,
00:46about 3 meters wide and 2 to 3 meters wide.
00:49But closed, the space becomes minimal,
00:52and you would be close to a large language like a car.
00:56In addition, these baleines are nourished by filtration,
00:59and not by chasse.
01:01They engloutisent an enormous amount of water,
01:03then they rejettent through their fanon,
01:05which retient krill and petits poissons like a vivant.
01:09If an animal inattend is introduced to the inside,
01:13their reaction is simply to the expulser without delay.
01:16This was precisely the chance of Michael Packard,
01:19plonger confronted with such a scene in 2021.
01:22While he collected a homard at about 9 meters deep,
01:26he was suddenly engloutis.
01:28Everything became black,
01:29a pressure the envelope,
01:31and he felt that he went up.
01:33He is estimated to stay 30 to 40 seconds
01:35in the mouth of the baleine
01:36before it emerges,
01:38then it emerges,
01:38then it immediately breaks like a chien
01:41throwing a citron.
01:43You understand it,
01:44when the baleine recognized that Michael Packard
01:46was not a proie,
01:48she was forced to go up to the surface.
01:51It's the only place where a baleine
01:53can correctly expulser what she has done by mistake.
01:56This leads to the fact that the baleine
01:58are mammifères
01:59and share so with you more traits
02:01that most of the animals marins.
02:03Contrairement aux poissons,
02:05they have no branchies.
02:06They breathe in the air
02:07thanks to the events placed
02:08at the summit of their heads,
02:10comparable to an immense narines.
02:12They must thus go up regularly
02:13to breathe.
02:14When they emerge,
02:16they breathe deeply,
02:18then,
02:18they inject a powerful souffle
02:20charged with brumes,
02:21like a forest.
02:22This famous jet
02:23corresponds to an expiration
02:24vigorous.
02:26According to the species,
02:27they can stay immerged
02:28between 20 minutes
02:29and more than an hour.
02:31But how does it work?
02:32Their lungs act like
02:34oxygen,
02:35while their muscles
02:36contain a large amount
02:37of myoglobin,
02:38a protein capable
02:40of stocking this oxygen
02:41for longer plunge.
02:42When they submerge,
02:44their cardiac rhythm
02:45ralentit,
02:46no more than a few times
02:47per minute,
02:48and the circulation
02:49sanguine
02:50is only directed
02:50towards the essential organs.
02:53It's like
02:53if all their organisms
02:54were in the mode
02:55economy of energy.
02:56And if it wasn't enough
02:58to impress,
02:59the balees
02:59at bosse
03:00have other remarkable capacities.
03:02They can,
03:03especially,
03:04chant,
03:04and it's the term scientific
03:06appropriate.
03:06The mâles
03:07produce a long
03:08sequence of
03:09sounds
03:09which can last several
03:11hours.
03:11These emissions
03:12are not chaotic,
03:14but have a
03:15structured structure
03:16almost musical,
03:17mêlant
03:18heavy notes
03:18and loud notes
03:19more.
03:20The most surprising
03:21is that these sounds
03:22can travel
03:22thousands of kilometers
03:23under the water.
03:24The sound
03:25propagates
03:25more efficiently
03:26than in the air,
03:27transforming the ocean
03:28into an immense
03:29hall of concerts.
03:30The waves
03:31can move
03:31and travel
03:32to vast distances,
03:34reaching other
03:35very far away,
03:36like a real
03:37network of marine communication.
03:39Only the mâles
03:40of balees and abos
03:41chant,
03:41and scientists think
03:42that this behavior
03:43occurs, especially during
03:45their reproduction period.
03:46Some say
03:47that these sounds
03:48serve
03:48to attract females,
03:50while others consider
03:51that they also allow
03:52to communicate
03:53or to rivalize
03:54with other mâles.
03:56What is particularly
03:57remarkable,
03:58is that all the mâles
03:59of the same region
04:00chant a similar song,
04:02which evolve progressively
04:03with the time.
04:05Every year,
04:06the melody
04:06remains globally
04:07recognizable,
04:08but slight changes
04:09appear a little
04:10during the season.
04:12When an individual
04:13introduces a variation,
04:15it can spread
04:15and become dominant.
04:17Sometimes,
04:18a new chant
04:19entirely new
04:19replaces the ancien
04:21and spreads
04:21from one population
04:22to another.
04:23researchers think
04:24that these balees
04:25learn each other
04:27and transmit
04:28their new chant
04:29across the ocean.
04:30The balees
04:31abos
04:31are among the most
04:32biggest
04:32of the animal's
04:34They travel thousands
04:36of kilometers
04:36from the cold areas
04:38where they nourish
04:40to reach
04:41the tropical areas
04:42where they grow
04:44and raise
04:45all their little
04:46They pass
04:47also a lot
04:48of time
04:48to nourish
04:49sometimes
04:50for 20 hours
04:50when the balees
04:52captured
04:52Packard
04:53by accident,
04:53they could not
04:55simply expel
04:56through the water
04:56and continue
04:57to eat.
04:58Their anatomy
04:58enables them
04:59to keep their mouth
05:00closed
05:00to prevent
05:03their lungs
05:04completely
05:05to relax
05:07and breathe
05:08they have to reach
05:10the surface.
05:10There,
05:12they inspire
05:13their gorge
05:15expulsed
05:15their gorge
05:16expulsed
05:16then reprennent
05:17their guleton
05:18as if nothing
05:19was there.
05:20It is in fact
05:21a remarkable conception
05:22made by millions
05:23of years of evolution.
05:25The balees
05:25lived once
05:26on the ground
05:27their ancestors
05:28appeared
05:29to hippopotamus
05:30who have
05:31progressively explored
05:32the marine environment.
05:34During the time
05:34their corps
05:35adapted
05:35to the aquatic life
05:36and their narines
05:39were moved
05:40to the summit
05:41of their heads
05:41without ever
05:42stop breathing
05:43the air.
05:44It is like
05:44the evolution
05:45does not create
05:46something from nothing
05:48but adapts
05:49what already exists.
05:50This evolution
05:51was precisely
05:53what is
05:53what was
05:54after being
05:56craché
05:56he remained
05:57still

06:24extraordinaire à raconter bien qu'une baleine à bosse ne puisse pas avaler pacard certaines
06:29créatures sur terre en serait théoriquement capable en tête figure le cachalot seul animal
06:35moderne dont la gorge soit suffisamment large pour engloutir un humain entier il se nourrit
06:40régulièrement de calmard géant mesurant jusqu'à 12 mètres ce qui rendrait un humain insignifiant
06:45en comparaison heureusement ces animaux vivent dans les profondeurs et se nourrissent presque
06:51exclusivement de calmard de poissons et parfois de requins les humains ne correspondent ni à leur
06:57régime habituel ni à leur proie naturelle sur terre le piton réticulé et l'anaconda vert compte parmi les
07:04plus grands serpents existants ces derniers ne mâchote pas leur nourriture ils l'avalent tout
07:09entière un piton adulte peut ouvrir sa mâchoire suffisamment pour engloutir un cerf ou un porc
07:15tandis qu'un anaconda peut maîtriser un capybara des récits non confirmés évoquent des cas où des
07:21humains auraient été avalés surtout dans des régions isolées même dans ce cas le processus
07:26durerait plusieurs heures et la digestion serait difficile pour l'animal contrairement aux mammifères
07:31les serpents ne possède pas les mêmes mécanismes respiratoires ou réflexes ce qui rendrait toute
07:36évasion impossible par de simples chatouillements de dessins animés et c'est à peu près tout heureusement
07:42pour nous à moins bien sûr de remonter très loin dans le passé jusqu'à la préhistoire à cette époque
