Les concombres de mer sont étonnamment chers, et voici ce qu'il en est. Il s'avère que certaines cultures les considèrent comme un mets délicat, ce qui a créé une demande de marché en plein essor. Les concombres de mer sont en quelque sorte l'équipe de nettoyage de la mer, filtrant et purifiant les fonds marins, ce qui leur confère une valeur écologique encore plus grande. Leur récolte est toutefois délicate, car elle nécessite des plongées méticuleuses et des manipulations soigneuses. De plus, leurs propriétés médicinales dans certaines médecines traditionnelles ajoutent une couche supplémentaire d'attrait, ce qui fait grimper leur coût. Ces bizarreries océaniques ne sont donc pas seulement des aspirateurs sous-marins ; elles nagent aussi dans une mer où la demande est forte et où leur prix est élevé !

00:08 to the soft bodies, the recyclers of nature. These exotic marine creatures may not be the first
00:14 pet to be imagined in one's home, but believe me, they have unique talents in their genus that are
00:20 worth a glance. Sea cucumbers are small colorful creatures, whose digestive system
00:25 consists mainly of a hole at each end. Their bodies are fat and soft, covered with a rough skin.
00:32 And guess what? They breathe through their buttocks and their quesfos. These amazing creatures have
00:38 indeed found a way to pull the best part of each part of their body, however small it may be.
00:44 You may be wondering what sea cucumbers do with their unique skills. Well,
00:50 they play a crucial role in the cleaning of the waters of our planet. They feed on all the
00:55 debris found on the seabed. Their digestive system decomposes debris and thus eliminates
01:00 all bad substances. It's a bit like little vacuum cleaners cleaning the bottom of the ocean.
01:05 Believe it or not, sea cucumbers are also very popular in the kitchen. They are harvested
01:11 and marketed in many countries. The Asian market in particular is in full swing. They are sold
01:18 cooked and dried under all kinds of fanciful names. If you prefer a more
01:23 spoken name, you can simply call them sea slugs. Now, you won't believe your eyes.
01:31 A dried sea cucumber can cost you up to $ 1,400 a pound. These viscous delights are really worth
01:37 their weight in gold. But let's go back in time a bit. The tradition of eating sea cucumbers
01:43 dates back a long way, more than a thousand years in Asia to be precise. And as demand for
01:49 these curious creatures has increased rapidly, this has led to an over-exploitation of local fisheries
01:55 and therefore to a decrease in sea cucumber stocks in many countries. Not good
02:00 for our little sea cucumbers friends. So, the need to find them elsewhere quickly made itself felt.
02:05 One of the most interesting examples of sea cucumbers is the Hennepiniast.
02:10 Not only does it have an amazing appearance, but it also has an excellent
02:16 defense system that allows it to use bioluminescence to scare its predators.
02:21 Fortunately, brilliant researchers from all over the world have decided to act and have set out
02:25 for the mission of raising sea cucumbers and rebuilding exhausted stocks. They are also
02:30 studying how these creatures can be a reasonable food resource and contribute
02:35 to reducing damage caused by fish farming. In Scotland, for example, a team of enthusiastic
02:41 researchers has created a company for this specific purpose. Their goal? To understand how
02:46 sea cucumbers are able to absorb so many harmful substances in water. They could
02:50 well be the aquatic superheroes we were waiting for. Meanwhile, in Sweden, marine biologists
02:56 are working hard to restore the population of Cucumaria Miniata. These poor creatures
03:02 have disappeared from local waters due to fishing, but specialists are determined to
03:06 give them a second chance. In parallel, they are also studying how sea cucumbers can
03:12 integrate into the culture of sea products. Their laboratories are located in one of the
03:17 marine cucumber gardens, where they deal with the soy of the approaching general
03:21 region of the Sesame Valley in the Atlantic. And let's forget about Canada. There,
03:27 the researchers are focusing on the Apostischopus californicus. These magnificent sea cucumbers
03:33 can measure up to 50 centimeters in length and are perfectly suited to co-cultivation
03:38 with other species. They are even trying to put open the systems of species that allow
03:43 them to preserve more easily the cucumbers of the sea where they are most useful.
03:48 Speaking of amazing marine creatures, have you heard of a fish that can fly?
03:54 You heard right. We are about to discover a world where swimmers can fly,
03:59 and where the ocean becomes a landing site for these air acrobats. You won't believe
04:04 your eyes, it's not me who wrote that. So, imagine the scene. You are lying in the
04:12 hot waters of the ocean. You don't care what it is, when suddenly you see a fish
04:20 flying in the air like a torpedo. And yes, they exist well and they have a sacred style,
04:28 with their elongated bodies and their pectoral fins that look like wings. These are the great
04:34 flying beings of the ocean. So, you may be wondering why a fish needs to fly? Well,
04:40 it turns out that these magnificent creatures have developed this ability to glide to escape
04:44 their underwater enemies. And they have a lot of enemies. And all of them are very
04:50 frightening, tasty flying fish. As for the diet of these flying creatures,
04:55 it is made up of a wide variety of snacks, because these fish are truly greedy.
05:00 They love, for example, the plankton, "Miam", who would have thought that tiny floating organisms
05:07 could be so delicious. Let's take a closer look at the album of flying fish families.
05:13 About forty species are known to hover in the sky. And here's a funny fact, all these species
05:19 have a forked and asymmetrical tail, the lower lobe being longer than the upper lobe.
05:25 Besides, it reminds a bit of the fish version of a bizarre hairstyle. And that's not all,
05:30 some of these funny flying creatures even have oversized pelvic fins,
05:34 which gives the impression that they have four wings. Can you imagine the jealousy of the rest of the
05:40 fish when they see Bontch pass his fashion pioneers? Now, let's get to the heart of the matter,
05:46 their aerial exploits. Flying flying fish is a real show.
05:51 First of all, it takes speed underwater to reach a lightning-fast speed of 37 miles per hour.
05:59 It's faster than some speed limits of cars. Then, like a rocket ready to take off,
06:05 it tilts upwards and breaks the surface of the ocean to fly away. But it doesn't stop there.
06:10 These amateurs of strong sensations can reach heights of more than a meter in the air.
06:16 Can you imagine the view from above? They soar in the sky and fly long distances,
06:21 the equivalent of a fish marathon. They are the best reporters. When they approach the
06:28 water again, they can fight from the tail and continue their flight without returning completely
06:32 into the depths. These flying fish are also adepts of nightlife. Just like
06:38 fireflies squeeze around a sparkling disco ball, flying fish are attracted by light.
06:44 The clever fishermen take advantage of it and set up canoes with just the right amount of water
06:50 so that the fish are comfortable but cannot escape. They then add a
06:55 lightness to the scene and in a blink of an eye, the flying fish are captured from one place to another,
07:01 offering an abundant harvest to the lucky fishermen. Do not worry, these flying fish
07:06 are not on the list of species on the verge of extinction. At least, not yet.
07:10 The next time you are at sea, be careful. We never know when we can
07:15 attend a flying fish show. Our next adventure takes us to the eccentric world of underwater romance.
07:22 Imagine a scene where someone is doing tango with his lunch. Wait what? No, it's not a
07:29 vomit contest, I promise you. We are now going to dive head first into the
07:34 tango coupling ritual. These curious creatures have chosen a home in the coral reefs
07:40 of the Caribbean and West Atlantic Ocean and they know how to give themselves a show.
07:45 Forget the flirting phrases or gallant gestures. These fish with jaws rely on
07:50 the unique movements of their jaws to pursue their potential partner. It's like a dance contest,
07:56 but with the mouth. Not only are these fish skilled in the art of picking up sand,
08:01 but they are also acidic parents. So much hidden talent. The males pass their parental duties
08:07 to the higher levels, carrying the precious eggs in their giant mouths until they are ready
08:12 to hatch. It's like they have their own aquatic nursery. When they are not busy
08:18 feeding their offspring, these jawfish transform their mouths into fighting tools.
08:23 And yes, it's time for the fighting championship. They are facing each other in epic battles of
08:29 strength and buccal agility. Mouth against mouth. Do you know the old adage "join the gesture
08:36 to the word"? Well, it's "all in the mouth" that applies it to a whole other level. Whether it's
08:43 romance, parentalism or friendly competition, the "all in the mouth" show us that acts are
08:49 sometimes more eloquent than words. They can sometimes feel like they are having a bad experience.
08:54 But rest assured, it is their unique way in the world to express themselves and find love.
