00:00 Hi everyone!
00:02 We think that everything relevant in terms of biology and geography has already been discovered.
00:06 However, scientists say that only one third of our land and oceans have been studied.
00:11 There are still hundreds of kilometers of taiga, tundra and desert where no human being has ever set foot.
00:16 Imagine how many unusual animals we could discover there.
00:19 Maybe there is a megalodon or a frightening shark waiting for us in the depths of the ocean.
00:23 However, it is useless to make great trips to see such exotic animals.
00:27 Today, we are going to show you incredible species that are very rarely taken in photos.
00:31 Let's go!
00:32 The firefly jellyfish
00:42 They are composed of a strange fabric resembling jellyfish.
00:45 And on earth, their body looks like gelatinous balls.
00:48 However, this species seems to have surpassed all the others.
00:51 It looks more like a real multicolored firefly explosion.
00:54 But you have to be lucky enough to be able to observe this magnificent specimen.
00:57 Because this species lives at a depth of about 1500 meters in a single area of the Pacific Ocean, not far from the Gulf of California.
01:03 The water pressure is about 150 kg per square centimeter.
01:06 It is therefore impossible to dive it underwater.
01:09 Only a robust batisca can reach the bottom safely.
01:12 And scientific expeditions in this area are very rare.
01:14 That's why you see the first and certainly the only clichés of this unattainable jellyfish.
01:19 It is amazing how this unique organism of its kind manages to survive in all safety in such dangerous depths.
01:24 And above all, where does its unique color come from?
01:26 It seems that the abyss still hides many secrets.
01:29 A lizard fan
01:31 Every time we hear about the discovery of a new animal species,
01:35 we often think that it is a kind of small insect or a micro-organism.
01:39 But it happens that Mother Nature is messing with us with new larger creatures.
01:42 A few years ago, scientists discovered a new species of lizard with a fan-shaped neck.
01:48 The lizard has been filmed several times by amateurs, but was only scientifically classified in 2018.
01:53 It was called Cytana Athenboroughi, in honor of Sir David Athenborough,
01:57 historian of natural sciences and amateur of British radio.
02:00 The most striking feature of this reptile is its multicolored fan that extends from its head to the middle of its belly.
02:05 Only males have this unusual excretion.
02:08 It serves as their main tool to attract females.
02:10 To display their flawless appearance, males raise their heads high, inflate their fan and swing slightly from one side to the other.
02:16 There are similar lizards in neighboring countries, but only this new variety has such an unusual color.
02:21 Of course, such a brilliant fan will attract the attention of big predators.
02:25 But apparently, it is more important for these lizards to show themselves than to stay safe.
02:29 The red cobra
02:31 We are ready to bet that when you heard the word "cobra",
02:34 you imagined a creature with a sand color or rather grayish, with a kind of bell-shaped head.
02:39 So what do you think of this red species?
02:44 So no, it's not due to a mutation or an accident with a paint pot,
02:47 but it's a kind of cobra-sniffer.
02:49 These reptiles live in the arid climate of East Africa, where the soil has a reddish hue, and sometimes even brown-red.
02:54 Naturally, these snakes have to adapt to their environment, which results in their particular hue.
02:59 And there is nothing to say, this species stands out from many of its congeners.
03:02 Despite its aggressive colors, these snakes are not known to be aggressive towards humans.
03:06 Their venom causes gnawing and gnawing at the bite level, but without affecting the nervous system of humans.
03:12 However, the most terrifying thing about this red cobra is its ability to spit venom at a distance of 1.5 to 2 meters.
03:18 It happens that the venom reaches the eyes or the mouth, which can have devastating consequences.
03:22 So if you ever run into a red cobra at home, don't try to make a friend,
03:26 and call the emergency services immediately.
03:28 The golden tiger
03:30 We are not talking about a golden statue of an animal that took life,
03:33 but we are going to show you a phenomenon just as amazing.
03:36 Here is an unpublished scene of one of the rarest tigers on our planet.
03:39 Due to a rare mutation, the color of this wild animal has changed from orange to gold.
03:43 In addition, there are only 30 tigers of this color left in the world,
03:46 and most of them live either in private reserves or in zoos.
03:49 In 2014, a female of this color was found in an Indian natural reserve.
03:53 But in 2019, scientists have completely lost track of this animal.
03:57 Golden tigers are not separate species, but represent a rare genetic anomaly.
04:01 Thanks to this particular gene, golden tigers can be born completely white,
04:05 or even devoid of their usual black stripes.
04:07 This gene has also led to a golden coloration,
04:10 smaller and closer black lines, as well as a more pronounced white fur.
04:13 It is not surprising that these tigers are very popular with poachers and collectors,
04:17 which explains why this unique mutation could soon simply disappear.
04:21 The white bat or durian
04:23 Get ready to see the most unusual of all bats.
04:26 These small balls of hair are white bats native to Honduras.
04:29 It is the only animal of this kind that has a white fur and ears as well as a yellow nose.
04:33 To be able to move and hunt more easily,
04:35 classic bats have a short, black fur,
04:38 but these have apparently decided not to do like the others.
04:40 No, but imagine if Batman wore a white suit.
04:43 These little animals also use an interesting method to sleep during the day.
04:46 Since these little creatures live in tropical forests,
04:49 they cannot hide from the sun in rocks or caves, like the forest of other species.
04:53 Instead, they build a kind of shelter with leaves and sleep there in small groups.
04:57 At night, they leave their hideout and go hunting.
04:59 However, instead of hunting caeleopterans or small birds,
05:02 Honduran white bats feed on a particular species of fig.
05:05 Scientists think that it is this particular diet
05:08 that has made the fur of animals turn white and their noses and ears yellow.
05:12 The rainbow bat
05:14 Even if you don't really like insects,
05:16 you have to admit that there are some really beautiful ones.
05:18 Like for example this harmless species that looks more like a fragment of a rainbow.
05:22 Admit that it's a bit of a bore.
05:23 This species is called Doctylotumbicolor, or simply rainbow bat.
05:28 Its amazing, shaggy and multicolored envelope.
05:30 You can see black, dark blue, yellow, white and red.
05:33 It is rare to be able to observe such a colorful species in a natural environment.
05:36 So how could a simple bat get such a pretty color?
05:39 In fact, it turns out that these vivid shades warn predators that the insect is venomous
05:43 and that it should not be eaten.
05:44 Do you remember poisonous blue and red frogs?
05:46 Well, it's the same principle.
05:48 But in reality, these insects do not contain poison in their shit.
05:51 Scientists conducted an experiment on lizards.
05:53 They were presented with two similar types of bats.
05:56 One was rainbow colored and the other had a sandy shell.
05:59 Curiously, these predators did not pay attention to the colored individuals and left them alive.
06:03 Thus, the beautiful coloration of insects does not only attract females,
06:06 but also repels some predators.
06:08 The Seneca's white deer.
06:10 If you think that the white deer does not appear among fairy tales, look at this.
06:14 These white animals like snow walk freely in the county of Seneca in New York state.
06:18 And no, they are not albinos.
06:20 In fact, there is a gene called recessive that discolors their fur.
06:23 This means that these white deer can be born to each generation.
06:26 So they are quite common.
06:27 However, they are easily spotted by predators and hunters.
06:30 And they would not survive in the wild.
06:32 Fortunately, good Samaritans are there to help them.
06:34 There was once a military base and a huge ammunition depot,
06:37 with a restricted area in the Seneca region.
06:39 White animals were spotted there in the 1950s,
06:42 but were forbidden to hunt by the head of the base.
06:44 After the dissolution of the depot in 2000,
06:46 it turned out that about 700 white deer lived on this territory.
06:49 Today, they are quite popular.
06:50 And not by poachers, but by buses full of tourists
06:53 who come to have the chance to observe these beautiful creatures out of the ordinary.
06:56 The Blue Iguana
06:58 Some animals strangely look like mythical creatures.
07:01 It must be recognized that this blue iguana looks like a dragon without wings.
07:04 Who knows, maybe in the past, these fire-breathing monsters
07:07 would have lost their ability to fly and would have turned into small reptiles.
07:10 If so, bad news, because the descendants of the latter threatened extinction.
07:14 The blue iguana only lives on the island of the Grand Caïman in the Caribbean Sea.
07:17 This beautiful lizard does not support captivity well
07:19 and needs reproductive conditions and adapted food.
07:22 With the development of tourism and the destruction of fruit plantations,
07:25 its number began to decrease considerably.
07:27 These very slow reptiles are often attacked by cats and dogs.
07:30 All this led to only 15 lizards left on the island in 2003 capable of reproducing.
07:34 The situation has certainly improved, but blue iguanas are still in great danger.
07:38 Females can only lay eggs once a year.
07:40 Fortunately, it is possible that our descendants can still see these magnificent creatures,
07:44 because they have an average life expectancy of 30 to 50 years.
07:47 The albino cobra
07:49 Albinos are quite rare, and most animals suffer only rarely from this mutation.
07:54 Among the latter is a cobra, and this is very rare.
07:57 Fortunately, we have the Internet to explore every corner of the globe.
08:00 According to some researchers, the albino cobra is one of the 10 rarest animals in the world.
08:05 People have been amazed by the beauty of these snakes since antiquity
08:08 and have often attributed a mystical power to their color.
08:10 That's why they tried to kill these mutant snakes as soon as they saw them,
08:13 so that they would not cause any harm.
08:15 Nowadays, humans are more rational.
08:17 However, albino cobras have become very rare in the wild,
08:20 and many are those who, in captivity, do not even manage to live until adulthood.
08:24 A black baby seal
08:26 We talked about albinos and white animals, but what about entirely black specimens?
08:31 It turns out that there are also creatures of dark color.
08:33 So here we have a perfectly black-furred seal.
08:36 It's a normal phenomenon, but it's still quite rare.
08:38 After all, seals like cold climates, and black fur is far too hot for that.
08:42 This color is also dangerous in the wild.
08:44 The animal becomes too visible on a gray rock background and in clear water.
08:47 Because of predators, hunters and a poor ecology,
08:50 most of these seals are either on the brink of extinction,
08:52 or closely followed by the authorities responsible for the protection of the fauna.
08:55 Nevertheless, its dark-furred coating is absolutely incredible.
08:58 The parents of this seal must be jealous of its sumptuous coating.
09:01 The anisotrope of the maple
09:04 Let's finish this video on insects.
09:06 It turns out that butterflies are not the only ones to have colored wings with multiple patterns.
09:10 This night butterfly is also a real fashion phenomenon.
09:13 Look at its pink and yellow wings, and this pretty orange duvet on its head.
09:16 It is a pink anisotrope of the maple,
09:18 a fairly common insect species in eastern United States.
09:21 Larvae feed on leafy leaves, and prefer in particular maple and oak,
09:25 while adults eat and never drink.
09:27 Curiously, their unusual appearance helps them hide from birds in the leaves.
09:31 There is also a theory that predators confuse these insects with venomous species.
09:36 All we can say is that this night butterfly is a real work of art.
