00:00:37,541 --> 00:00:39,661 Their alien appearance 4 00:00:41,541 --> 00:00:44,021 combined with amazing intelligence. 5 00:00:44,100 --> 00:00:45,300 independence 6 00:00:45,381 --> 00:00:47,181 and ingenuity. 7 00:00:49,300 --> 00:00:51,860 We still have so much to learn 8 00:00:51,940 --> 00:00:55,020 about these rarely seen legends of the depths. 9 00:00:59,299 --> 00:01:02,899 About stranger animals than the most fantastic fiction. 10 00:01:07,899 --> 00:01:12,378 OCTOPUS 11 00:01:14,818 --> 00:01:19,898 VANCOUVER ISLAND CANADA 12 00:01:25,617 --> 00:01:28,497 Nutrient-rich waters make it the sea 13 00:01:28,577 --> 00:01:31,057 one of the most productive on the planet. 14 00:01:34,577 --> 00:01:37,816 An ideal place to start a new life. 15 00:01:39,977 --> 00:01:44,576 DEPTH 25 M WATER TEMPERATURE 5°C 16 00:01:44,656 --> 00:01:46,296 Deep underwater… 17 00:01:48,576 --> 00:01:49,856 ...in the secret world... 18 00:01:54,215 --> 00:01:57,055 ...hundreds of thousands of precious eggs. 19 00:02:00,894 --> 00:02:04,014 Each is no larger than a grain of rice. 20 00:02:11,293 --> 00:02:14,534 She carefully protected them for six months 21 00:02:15,573 --> 00:02:16,373 their mother. 22 00:02:20,013 --> 00:02:22,293 Female giant octopus. 23 00:02:23,453 --> 00:02:24,373 Her body - 24 00:02:25,253 --> 00:02:26,372 their fortress. 25 00:02:29,132 --> 00:02:31,212 She pushes the water 26 00:02:31,292 --> 00:02:33,932 so that the algae does not suffocate her children. 27 00:02:36,452 --> 00:02:37,692 In every egg - 28 00:02:38,372 --> 00:02:42,532 tiny copy an almost impossible creature. 29 00:02:45,011 --> 00:02:46,091 Eight hands... 30 00:02:48,411 --> 00:02:49,891 ...three hearts... 31 00:02:51,291 --> 00:02:52,371 ...and blue blood. 32 00:02:55,691 --> 00:03:00,610 Over time they will become 250,000 times heavier. 33 00:03:02,569 --> 00:03:05,690 And they will be one of the most cunning predators in the ocean. 34 00:03:09,169 --> 00:03:10,929 But few will live to see this. 35 00:03:20,929 --> 00:03:23,648 It's time to leave the safety of the cradle. 36 00:03:38,967 --> 00:03:41,607 Having received the last breath from my mother... 37 00:03:43,927 --> 00:03:47,206 …baby swims away carried away by ocean currents. 38 00:03:53,885 --> 00:03:55,925 She will never see her mother again. 39 00:04:04,165 --> 00:04:05,405 She's all alone 40 00:04:06,604 --> 00:04:08,404 at the mercy of the sea. 41 00:04:20,043 --> 00:04:21,524 If she survives 42 00:04:21,603 --> 00:04:22,843 it will take its place 43 00:04:22,923 --> 00:04:27,683 in one of the most incredible animal families on Earth. 44 00:04:39,042 --> 00:04:40,522 They are in every ocean. 45 00:04:42,401 --> 00:04:45,522 There are more than 800 species of octopuses 46 00:04:47,282 --> 00:04:48,081 squid 47 00:04:49,201 --> 00:04:50,601 and cuttlefish. 48 00:04:53,081 --> 00:04:54,441 These are cephalopods. 49 00:04:57,520 --> 00:05:00,720 Which literally means “cephalopods.” 50 00:05:01,760 --> 00:05:03,880 All because of their peculiar anatomy 51 00:05:04,520 --> 00:05:07,320 with limbs growing from the face. 52 00:05:10,639 --> 00:05:13,480 But the earliest cephalopods more like this. 53 00:05:15,679 --> 00:05:16,639 Nautilus. 54 00:05:18,919 --> 00:05:21,599 He looks like to his distant relative. 55 00:05:21,679 --> 00:05:22,639 On a snail. 56 00:05:25,118 --> 00:05:29,038 He remained unchanged half a billion years... 57 00:05:32,438 --> 00:05:37,317 Whereas everyone else changed in the most amazing way. 58 00:05:38,277 --> 00:05:40,197 They dropped their shells 59 00:05:41,517 --> 00:05:44,677 becoming more flexible and agile. 60 00:05:46,397 --> 00:05:50,156 They were able to explore previously inaccessible places. 61 00:05:53,676 --> 00:05:54,876 Their fluid form 62 00:05:54,956 --> 00:05:59,036 able to withstand even destructive pressure at depth. 63 00:06:01,515 --> 00:06:03,795 But without a protective shell 64 00:06:03,875 --> 00:06:05,915 Cephalopods have become easy targets. 65 00:06:07,915 --> 00:06:12,394 They developed almost supernatural abilities 66 00:06:12,475 --> 00:06:13,715 to survive... 67 00:06:19,914 --> 00:06:22,954 ...and survive in a sea full of predators. 68 00:06:23,873 --> 00:06:28,753 CAPE PENINSULA SOUTH AFRICA 69 00:06:30,953 --> 00:06:34,753 DEPTH 5 M WATER TEMPERATURE 15°C 70 00:06:36,833 --> 00:06:39,672 The ocean can be a very scary place... 71 00:06:41,953 --> 00:06:44,512 ...if you are the size of a matchbox. 72 00:06:47,792 --> 00:06:50,032 It’s better not to attract attention here. 73 00:06:52,711 --> 00:06:55,551 But the little cuttlefish cannot hide forever. 74 00:07:00,831 --> 00:07:04,671 Fast metabolism means that she is always hungry. 75 00:07:10,190 --> 00:07:12,549 Her favorite food lives in shallow water. 76 00:07:14,510 --> 00:07:16,549 Only 20 meters. 77 00:07:22,629 --> 00:07:26,589 But for a small creature this is a whole journey... 78 00:07:30,828 --> 00:07:32,429 ...full of dangers. 79 00:07:38,908 --> 00:07:40,387 She swims well. 80 00:07:41,947 --> 00:07:44,227 But the fish are faster. 81 00:07:48,627 --> 00:07:50,627 And she has sharp eyesight. 82 00:07:52,907 --> 00:07:57,387 But cephalopods can merge with the environment. 83 00:08:05,066 --> 00:08:06,666 And the cunning cuttlefish - 84 00:08:07,666 --> 00:08:10,386 a true master of disguise. 85 00:08:12,025 --> 00:08:13,945 Special muscles on the skin 86 00:08:14,505 --> 00:08:20,064 form thousands of shoots known as "tubercles" 87 00:08:22,224 --> 00:08:23,985 making it look like seaweed. 88 00:08:29,544 --> 00:08:31,143 Looks like the trick worked. 89 00:08:35,504 --> 00:08:38,503 This is not the only outfit in her collection. 90 00:08:41,223 --> 00:08:44,982 In a split second she can take on any form. 91 00:08:51,782 --> 00:08:52,862 Snail. 92 00:08:58,502 --> 00:08:59,301 Coral. 93 00:09:02,941 --> 00:09:03,901 Or stone. 94 00:09:10,780 --> 00:09:14,100 Amazing ability change color 95 00:09:15,500 --> 00:09:17,780 Cephalopods are obliged to chromatophores. 96 00:09:19,500 --> 00:09:24,140 These are millions of tiny cells filled with pigment. 97 00:09:24,899 --> 00:09:29,059 They swell and contract like balloons... 98 00:09:33,699 --> 00:09:36,738 allowing you to quickly change color. 99 00:09:44,298 --> 00:09:48,617 Ideal skill to blend into the background in a split second. 100 00:09:55,777 --> 00:09:58,776 Cephalopods can easily wipe the noses of chameleons 101 00:10:00,296 --> 00:10:04,536 possessing the most sophisticated a system of camouflage among animals. 102 00:10:12,296 --> 00:10:16,935 Usually this disguise is enough to protect the tuberculate cuttlefish. 103 00:10:20,695 --> 00:10:22,375 But when all else fails... 104 00:10:32,374 --> 00:10:33,334 Smokescreen. 105 00:10:40,933 --> 00:10:43,053 Slime-enriched ink beads 106 00:10:43,133 --> 00:10:46,093 imitating its silhouette and size. 107 00:10:48,733 --> 00:10:52,132 Having placed the deceptions, she runs away. 108 00:10:57,092 --> 00:10:58,452 Unlike octopuses, 109 00:10:58,532 --> 00:11:00,572 Cuttlefish have an internal shell. 110 00:11:01,451 --> 00:11:03,211 Built-in life vest 111 00:11:03,292 --> 00:11:05,372 makes them excellent swimmers. 112 00:11:06,531 --> 00:11:10,211 But after such a long time and eventful journey 113 00:11:10,291 --> 00:11:12,051 she was seriously hungry. 114 00:11:41,249 --> 00:11:42,208 Transformation. 115 00:11:44,288 --> 00:11:45,088 Ink. 116 00:11:46,768 --> 00:11:48,568 Even limb regeneration. 117 00:11:50,768 --> 00:11:56,047 Cephalopod superpowers help them survive in dangerous waters. 118 00:12:06,767 --> 00:12:09,726 Back to Canada where the success story awaits us 119 00:12:10,286 --> 00:12:12,686 despite enormous obstacles. 120 00:12:21,165 --> 00:12:25,005 Giant female octopus turned one year old. 121 00:12:27,245 --> 00:12:29,805 And it has already become 2000 times larger. 122 00:12:31,564 --> 00:12:33,685 But there is still a long way to go. 123 00:12:37,724 --> 00:12:41,524 Only one in 30,000 survives until adulthood. 124 00:12:48,203 --> 00:12:49,523 To reach the goal 125 00:12:50,123 --> 00:12:53,443 she will have to rely on your exceptional vision. 126 00:12:55,723 --> 00:12:57,042 Each eye of an octopus 127 00:12:57,123 --> 00:13:00,283 sees more what we see with both eyes. 128 00:13:03,722 --> 00:13:05,442 And looking with two eyes... 129 00:13:10,282 --> 00:13:11,601 ...she won't miss anything. 130 00:13:13,961 --> 00:13:16,041 Not limited to a hard skull 131 00:13:16,121 --> 00:13:18,641 eyes move independent of each other. 132 00:13:19,601 --> 00:13:24,681 And she can watch simultaneously forward and backward. 133 00:13:25,480 --> 00:13:29,040 The viewing circle is almost 360 degrees. 134 00:13:34,199 --> 00:13:35,920 This allows her to search for food... 135 00:13:38,239 --> 00:13:41,439 ...and be on guard in case of danger. 136 00:13:45,519 --> 00:13:49,079 Like all octopuses it consists almost entirely of protein. 137 00:13:56,758 --> 00:13:58,358 And everyone strives to bite. 138 00:14:06,877 --> 00:14:09,957 It's big enough to fight off sea bass 139 00:14:11,757 --> 00:14:15,557 But there is always bigger hungry predators. 140 00:14:32,115 --> 00:14:34,275 She needs to be on her guard. 141 00:14:39,874 --> 00:14:41,674 In the absence of parental care 142 00:14:41,755 --> 00:14:46,394 young octopuses need to be combined natural curiosity and caution. 143 00:14:50,554 --> 00:14:54,713 In an ever-changing ocean they need to learn quickly. 144 00:14:55,953 --> 00:15:00,953 FERNANDO DE NORONA BRAZIL 145 00:15:09,312 --> 00:15:10,672 When the tide goes out 146 00:15:11,392 --> 00:15:13,272 predators appear 147 00:15:14,352 --> 00:15:17,152 in search of prey brought by the waning sea. 148 00:15:18,151 --> 00:15:22,911 DEPTH 0—1 M WATER TEMPERATURE 26—45°C 149 00:15:26,271 --> 00:15:27,951 The victim is locked among the rocks. 150 00:15:33,390 --> 00:15:36,870 Nine month old Brazilian reef octopus 151 00:15:40,629 --> 00:15:42,549 It is cut off from the receding ocean 152 00:15:43,470 --> 00:15:45,309 and will not be able to live here for long. 153 00:15:53,948 --> 00:15:58,268 But this resourceful young octopus not ready to give up. 154 00:16:14,227 --> 00:16:15,387 And above it 155 00:16:15,467 --> 00:16:16,907 exactly this moment 156 00:16:16,986 --> 00:16:21,146 an army of red stone crabs was waiting. 157 00:16:22,707 --> 00:16:26,546 Low tide is their chance to find food on bare rocks. 158 00:16:29,626 --> 00:16:32,745 At first it seems like they are trying stay dry... 159 00:16:35,145 --> 00:16:39,785 ...jumping ten times the length of its body. 160 00:16:47,144 --> 00:16:51,864 But if the goal is too far, they still have to plunge. 161 00:17:11,422 --> 00:17:15,622 The attempt failed. It was a carefully thought out ambush. 162 00:17:17,302 --> 00:17:21,342 The young octopus learned the usual path of crabs. 163 00:17:24,981 --> 00:17:27,741 His incredible strategic talent... 164 00:17:33,100 --> 00:17:36,341 ...implemented by a very unusual brain 165 00:17:37,460 --> 00:17:39,340 distributed throughout the body. 166 00:17:40,100 --> 00:17:44,179 Two thirds of neurons are located in the limbs. 167 00:17:46,340 --> 00:17:49,780 Taught by experience he knows when to retreat 168 00:17:50,860 --> 00:17:52,059 when to attack. 169 00:18:29,056 --> 00:18:34,416 It paralyzes the crab introducing poisonous saliva from a hidden beak 170 00:18:35,976 --> 00:18:40,335 and waits for her enzymes liquefy his insides. 171 00:18:41,815 --> 00:18:43,536 Nutritious crab cocktail. 172 00:18:46,375 --> 00:18:48,975 He needs five of these a day to grow 173 00:18:49,535 --> 00:18:51,934 and he works tirelessly. 174 00:19:04,934 --> 00:19:07,853 The midday sun dries up its small swimming pool... 175 00:19:11,053 --> 00:19:14,333 ...threatening to leave him stranded. 176 00:19:20,013 --> 00:19:23,452 And since he breathes through moist gills 177 00:19:24,172 --> 00:19:25,931 without water he will suffocate. 178 00:19:29,212 --> 00:19:31,331 There are still a few hours before high tide. 179 00:19:34,411 --> 00:19:36,571 But he came up with a cunning plan. 180 00:19:40,691 --> 00:19:45,410 In the recess behind the head it stores water to breathe. 181 00:19:52,050 --> 00:19:54,570 This way he will gain a few more minutes. 182 00:20:02,408 --> 00:20:06,729 This respite allows him to do the unthinkable. 183 00:20:22,008 --> 00:20:23,807 He crawls on land. 184 00:20:31,127 --> 00:20:34,686 You need to act quickly until it dries. 185 00:20:41,166 --> 00:20:43,845 His fluid body is no longer weightless. 186 00:20:45,406 --> 00:20:47,845 And his organs may fail. 187 00:20:52,885 --> 00:20:55,764 Search for another pool - risky strategy. 188 00:20:57,485 --> 00:21:02,325 But cunning and calculation they won't let him get caught. 189 00:21:17,243 --> 00:21:18,843 The more difficult the test, 190 00:21:18,923 --> 00:21:21,562 the more inventive become cephalopods. 191 00:21:30,482 --> 00:21:33,842 Bad Sands in which there is nowhere to hide. 192 00:21:36,481 --> 00:21:38,401 LEMBE STRAIT INDONESIA 193 00:21:38,481 --> 00:21:42,561 DEPTH 5 M WATER

00:21:58,000 --> 00:22:01,999 Wunderpusconfuses predators with his strange behavior. 198 00:22:03,719 --> 00:22:07,079 Blue-ringed octopus signals with deadly poison. 199 00:22:10,199 --> 00:22:12,759 Others are more creative. 200 00:22:16,519 --> 00:22:20,318 The short-armed octopus seems to regret that he dropped his shell 201 00:22:20,878 --> 00:22:22,718 millions of years ago. 202 00:22:28,998 --> 00:22:31,517 And if we’re looking for a replacement for armor, 203 00:22:32,437 --> 00:22:35,397 it is important to choose the right size. 204 00:22:45,796 --> 00:22:48,316 Ideal protection
