00:00 Whales filmed trapping their prey with a rather dubious technique,
00:03 someone filming a cheetah meowing like a cat, or the "Glass Gem",
00:07 a mysterious variety of corn in the color of the rainbow.
00:10 You think you've seen it all in life, but here are the things you'll see for the first time here in this video.
00:15 Let's go!
00:16 You walk around the Traycross Zoo in Atherton, England,
00:20 and here you stop right in front of the primates' enclosure.
00:23 And there, two individuals attract your attention.
00:25 They are so intriguing that it drives you crazy.
00:27 You get the impression that they have nothing to do with monkeys apart from their walk and their mouth.
00:31 Because the body of these two specimens is as smooth as yours.
00:35 You are very shaken when you see this amazing spectacle.
00:37 In fact, they are two chimpanzee brothers living in the zoo and suffering from alopecia,
00:41 a pathology that refers to the acceleration of hair loss,
00:44 a bit like your uncle Gustave.
00:46 It's the equivalent of baldness in humans.
00:49 Except that in chimpanzees, this disease affects the whole body,
00:51 which means they have no fur and thus they get even closer to the human aspect.
00:56 The advantage is that this disease has made it possible to reveal their impressive muscles,
00:59 which, in normal times, do not appear under the hair.
01:02 If you are told "Madagascar", what do you think of?
01:05 You will surely think of its paradise beaches, the vani, the Baobab.
01:08 That's good. You have culture.
01:10 However, there is a corner of the country that you have never seen before.
01:13 The Tsingy of Behamra, or, so to speak, the place that you cross on the tip of your feet.
01:18 A gigantic mineral labyrinth,
01:20 made up of 157,000 hectares of rocks sharpened like knives.
01:23 A wonderful and breathtaking limestone decor,
01:26 essentially sculpted by the mosses that grow frequently in the country
01:29 and which attribute to the landscape an aspect of uniqueness.
01:32 This place has the particularity of sheltering a multitude of different ecosystems,
01:36 offering habitats to the different animal species of the island.
01:38 For example, it is a place very frequented by the Lumurians, who find the perfect refuge there.
01:43 We can also find the Bruchesia perarmata, a very small type of chameleon,
01:47 or other endemic species as well as 300 plant species,
01:50 which found in the natural reserve occupied by a large forest cover of more than 85,000 hectares
01:56 and a savannah, a real earthly paradise.
01:58 If you go there, it is the assured vertigo.
02:01 The Tsingy are the object of myths and cults for the local Malagasy population,
02:04 due to their very particular and very intriguing geological formation.
02:08 The site, classified as 1927, and has been registered since 1990
02:13 in the list of UNESCO World Heritage,
02:16 is today a flagship tourist destination to visit.
02:19 But despite this, if you decide to go there to explore the place,
02:22 be brave, because even if it is very beautiful and impressive, it is also very frightening.
02:27 If you see a shark in your own eyes, you will be extremely terrified and stressed.
02:31 Well, imagine that sharks, too, are stressed, except that they do not react like you.
02:35 They will not have cold sweats, nor rub their nails, nor cry a good blow.
02:39 They will simply vomit their guts.
02:41 Yes, you heard right.
02:43 Despite their reputation for being big eaters and devouring everything that passes under their fins,
02:47 when they find themselves in a stressful situation, for example,
02:50 trapped in a fishing net or being chased by a predator,
02:53 it is very likely that they will vomit their last meal, and even their stomach with it.
02:57 According to a scientist from Miami, this natural and instinctive reaction
03:00 comes from the fact that it is easier for them to escape the empty stomach.
03:03 The sharks thus get rid of what they have in their bowels to escape as quickly as possible.
03:08 It is a phenomenon called "gastric overdose".
03:11 A phenomenon not without danger, since it can lead to death if it happens out of the water.
03:15 Because without the movement of water and swimming, the shark cannot swallow its stomach.
03:20 Yes, you think they swallow it afterwards because they need it.
03:24 Sharks are not the only ones to do this in the animal kingdom.
03:27 Snakes and dolphins also have this ability to spit out their bowels
03:30 and swallow them afterwards after experiencing a stressful situation.
03:34 Apart from stress, this natural process allows the sharks to empty themselves
03:37 and to clean their bowels from time to time parasites
03:40 and indigestible food that they accidentally swallow.
03:43 You meet a friend by chance in the street and after talking to her for a long time,
03:47 you notice that she is holding a gold chain
03:49 to which a tiny bunch of purple grapes is attached.
03:52 You are intrigued and you can't help but interrupt her to satisfy your curiosity
03:57 and ask her why grapes are hung on her neck as a pendant.
04:01 Is this a new fashion? Are they there in case of small hollows?
04:04 You really want to know. Her answer surprises you.
04:07 These are not real grapes, but agate grapes,
04:09 a precious stone also known as calcedoine botryoide.
04:13 It is a variety of calcedoine, made up of quartz crystals
04:17 in the form of small jointing balls that strangely look like a grape vine.
04:21 However, analysis proves that despite its name, this stone is not really an agate.
04:26 It can be found in purple, but also in white, gray, green or even blue.
04:30 The agate grape is often found on the beach of Manakara,
04:33 on the Indonesian island of Sulawesi.
04:36 It is formed in lava, a cushion composed of andesite,
04:39 and thanks to the space left between these cushions, the stone takes shape.
04:43 The tectonics between the plates then takes care of going up the andesite
04:46 in the mountains of Sulawesi.
04:49 You have certainly already seen whales come out and jump out of the water.
04:52 It's a breathtaking spectacle.
04:54 However, what you have never seen before is the strange choreography they do in the water,
04:58 when they have a small hollow and want to eat.
05:01 As you can see from these images taken live off the coast of Alaska, on the island of Baranov,
05:05 a group of whales were filmed by drones, trapping prey and directing them to their buoyant mouths,
05:10 using a rather curious technique.
05:13 These animals use their fins to form bubble traps.
05:16 Very ingenious for cetaceans.
05:18 The technique is called pectoral herding.
05:20 It is sophisticated, but also very simple when you think about it.
05:22 It consists of performing a kind of rotation with their long pectoral fins
05:26 before the buoyant mouth is drawn to the surface of the water and surrounded by many circles of bubbles.
05:31 And it is in this movement that all the dexterity of the technique resides,
05:34 which allows the cetacean to create a kind of net of bubbles under the surface,
05:37 then to turn on himself with his pectoral fins stretched
05:40 in order to create a physical barrier that prevents the prey from escaping.
05:43 After which the whale guides its victims to its buoyant mouth to swallow them, and the job is done.
05:48 When you are called a feline, you think of these big wild animals
05:51 that, when they roar, shake the skies and the earth.
05:54 You may be right, but not as far as all felines are concerned.
05:57 There are indeed felines that would apparently make any human being with reason flee.
06:01 But when they open their mouths and you expect a fierce roar,
06:04 a small and ridiculous meowing escapes them.
06:07 These felines are none other than cheetahs.
06:10 Indeed, the cheetah meows like a cat, which makes it very unlikely at the ferocity level.
06:14 For example, in Namibia, a person filmed a cheetah meowing.
06:18 It's funny, but at the same time so cute.
06:20 Small question, when this bulldozer shook this tree,
06:30 what do you think the big cloud of dust that escaped from it was?
06:33 You can't guess?
06:35 Then look carefully.
06:36 These images were recorded in New Jersey, where pollen floods forests.
06:40 This bulldozer hit this tree, and it was so full of pollen
06:43 that when it was shaken, a big cloud of pollen escaped.
06:46 It was so thick that it took the shape of a tree.
06:49 A very surprising sight.
06:51 Achoo! Oops, sorry.
06:53 You know a lot of kinds of sharks.
06:55 White sharks, hammerhead sharks, whale sharks, tiger sharks.
06:59 But there is a kind of shark that you certainly don't know.
07:02 Besides, today is the first time you'll see it in your life.
07:05 This is the Greenland shark, or the Greenland hammerhead shark.
07:08 A species of shark that lives at 200 to 300 meters deep in the oceans.
07:12 It is one of the largest carnivorous sharks in the world,
07:14 with its cousin the white shark, but also one of the largest fish in the Arctic,
07:17 and certainly also the only polar water shark in North Atlantic.
07:21 If it is impressive, it is not because of its ferocity,
07:23 but rather because of its look of big, old, and sluggish stones.
07:27 It measures between 2.5 to 4.5 meters in length, and can even reach 7.3 meters.
07:32 And if I said "old", it's because I weigh my words.
07:35 This species of shark can live up to 400 years.
07:38 To calculate the age of a fish,
07:39 scientists count the layers of growth in the auricular stones,
07:42 which are calcium carbonate nodules found in their ears.
07:46 But cartilaginous fish, like sharks and rays,
07:49 which have a skeleton made up of cartilage instead of bones,
07:51 do not have these stones.
07:53 Scientists then proceed by sampling
07:55 the crystalline proteins of the shark's eye.
07:58 These proteins form at the embryonic stage
08:01 and remain the same throughout the animal's life.
08:03 They are then dated to radiocarbon
08:05 to allow approximately their age to be found.
08:07 The two largest sharks in Greenland are found to be
08:09 493 centimeters and 502 centimeters long,
08:13 and would be between 335 and 512 years old.
08:16 The image you are about to see is absolutely incredible.
08:19 In a forest, a tree has fallen, which can happen frequently,
08:22 either because of a violent storm or an earthquake.
08:25 But by falling on the ground,
08:26 this tree has allowed four other trees to grow
08:29 in its trunk over time,
08:30 a phenomenon never seen before.
08:33 However, don't ask me to give you a scientific explanation.
08:36 Nature is sometimes very surprising.
08:39 You have already eaten corn directly in its spleen.
08:42 It is a gourmet food that we love to taste,
08:44 especially in the countries of North Africa.
08:45 But for you, corn is young.
08:47 So look at this picture, you will be amazed.
08:49 It has been circulating on the Internet for some time,
08:51 and contrary to what you think,
08:53 it is not a trick,
08:54 and it is not a modified or modified product either.
08:56 It is the Glass Gem,
08:58 the mysterious variety of rainbow-colored corn.
09:02 According to a video published by Mother Earth News,
09:04 the father of this variety would be a certain Karl Barnes,
09:07 a descendant of Cherokee, a farmer from Oklahoma,
09:09 who would have wanted to grow corn at the end of the 1980s
09:12 in order to get a little closer to its origins.
09:15 He therefore crossed three varieties of corn
09:17 to create the rainbow corn.
09:20 In 1994, this farmer meets Greg Shon,
09:23 another farmer with whom he will collaborate
09:25 and to whom he will pass on all his knowledge,
09:27 as well as some seeds of his creation.
09:29 A decade later, Shon resumes the flambeau
09:31 and begins to cultivate, in turn, the Glass Gem,
09:34 this time on a large scale.
09:36 Today, North American farmers can do the same
09:38 by getting the seed in packets of 50 for 4.60 euros.
09:41 And if you ask yourself the question, the answer is no.
09:44 His popcorn is not multicolored.
09:47 Imagine yourself in this situation.
09:49 You fall in love with a very nice bamboo armchair
09:51 in a furniture and decoration store.
09:53 You buy it despite its high price,
09:55 but as it is a heartbreak, it does not matter.
09:57 You will enjoy your holiday budget.
09:59 And then, what really encouraged you to buy it
10:01 is that the dealer guaranteed you that it was made
10:03 with real natural bamboo and not processed.
10:05 You discover a few months later that he had not lied about it.
10:08 Since one day, when you go out in your veranda,
10:09 where you placed your armchair,
10:11 you discover that it has started to bud.
10:14 Indeed, the humidity has caused the bamboo
10:15 to restart its growing process
10:17 and to start budding as if it were a plant in a pot.
10:20 It's sure that it does not happen every day of things like that.
10:23 Now, tell us in the comments what you think
10:25 of these unusual things you see for the first time.
