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.
