last evidence of him. 92 00:08:26,061 --> 00:08:29,740 Due to the settlement of people and hunters he was exterminated for profit. 93 00:08:35,899 --> 00:08:39,578 Exists today very few marsupial

to adulthood. 105 00:10:30,514 --> 00:10:31,674 His main problem? 106 00:10:33,233 --> 00:10:34,353 Other devils. 107 00:10:42,632 --> 00:10:45,351 The little one cannot compete with the big ones. 108 00:10:47,671 --> 00:10:50,750 Two adults fight to divide the carcass. 109 00:10:57,388 --> 00:11:00,068 But he could steal a piece... 110 00:11:02,587 --> 00:11:04,188 ...while they fight. 111 00:11:31,421 --> 00:11:32,901 It’s better to eat quickly... 112 00:11:37,860 --> 00:11:39,700 ...until the troubles return. 113 00:11:57,776 --> 00:12:01,096 It remains for him just hope to eat the leftovers. 114 00:12:08,014 --> 00:12:12,773 But considering that the devil eats up to half your weight, 115 00:12:14,413 --> 00:12:15,892 the wait may be lengthy. 116 00:12:28,289 --> 00:12:30,849 At dawn his patience paid off. 117 00:12:32,929 --> 00:12:35,328 Well, almost. 118 00:12:39,287 --> 00:12:44,486 Only skin and bones remained but you don’t have to choose the little devil. 119 00:12:49,205 --> 00:12:51,884 Devils sometimes hunt themselves 120 00:12:51,965 --> 00:12:54,284 but the fallen are always welcome. 121 00:12:57,243 --> 00:13:03,522 The ability to eat inedible helped marsupials conquer the continent. 122 00:13:07,641 --> 00:13:11,200 KANGAROO ISLAND SOUTH AUSTRALIA 123 00:13:12,960 --> 00:13:17,719 Eucalyptus accounts for three quarters natural forests of Australia. 124 00:13:19,758 --> 00:13:22,038 Their leaves are so poisonous 125 00:13:22,118 --> 00:13:25,158 that they cannot eat almost no living creature. 126 00:13:30,156 --> 00:13:34,715 But one famous marsupial found a way to use 127 00:13:34,795 --> 00:13:37,075 this rich resource. 128 00:13:43,473 --> 00:13:46,673 Perhaps this mother is a koala seems a little tired 129 00:13:47,272 -->

--> 00:14:08,988 neutralizing the effect of poison from which we would fall into a coma. 133 00:14:18,266 --> 00:14:21,506 But such digestion not given to koalas from birth. 134 00:14:22,945 --> 00:14:24,265 It needs to be developed. 135 00:14:28,544 --> 00:14:31,944 Baby eats formula from milk and special gruel. 136 00:14:35,382 --> 00:14:39,261 This is mom's slimy droppings containing the necessary bacteria. 137 00:14:47,739 --> 00:14:53,338 But, although the problem of toxins has been solved, almost all the koala’s energy is gone 138 00:14:53,419 --> 00:14:55,978 for digestion these low-nutrient leaves. 139 00:14:59,177 --> 00:15:04,017 No wonder what they are doing 90% of your life is in your sleep. 140 00:15:19,173 --> 00:15:22,933 But not all marsupials lead such a relaxed life. 141 00:15:23,012 --> 00:15:26,332 ATHERTON PLATEAU QUEENSLAND 142 00:15:34,050 --> 00:15:36,009 This is a born base jumper. 143 00:15:39,169 --> 00:15:40,648 Sugar flying squirrel. 144

lifestyle supported by sugar syrup. 147 00:16:19,720 --> 00:16:23,120 But his teeth are too small to cut through thick bark. 148 00:16:34,837 --> 00:16:38,276 It's time to take a look to their larger cousins. 149 00:16:40,636 --> 00:16:43,235 Yellow-bellied flying squirrels. 150 00:16:46,634 --> 00:16:51,354 Their strong jaws quickly cuts through the strongest trees. 151 00:16:55,672 -->

00:17:15,509 --> 00:17:17,587 There are more and more guests at the party. 155 00:17:30,105 --> 00:17:32,905 So many uninvited guests it's already hard to ignore. 156 00:17:37,544 --> 00:17:39,183 The

160 00:18:09,817 --> 00:18:14,576 And in the Australian Alps the baby has already become a big child. 161 00:18:21,814 --> 00:18:25,134 He is already nine months old and he is almost an adult already. 162 00:18:30,532 --> 00:18:32,852 Well, almost. 163 00:18:38,291 --> 00:18:42,210 He will hide in the bag a few more months. 164 00:18:48,049 --> 00:18:50,248 Imitating my father 165 00:18:50,328 -->

00:19:14,763 She will endure until he turns one and a half years old. 169 00:19:15,843 --> 00:19:17,282 Then he will leave her 170 00:19:19,002 --> 00:19:20,601 to get to the top. 171 00:19:26,200 --> 00:19:29,359 After all, only the leader of the pack allowed to mate. 172 00:19:31,359 --> 00:19:33,079 And now the leader is dad. 173 00:19:42,997 --> 00:19:44,677 The opponent has returned. 174

with his birth 185 00:20:59,941 --> 00:21:02,780 he will lose the comfort of his mother's bag. 186 00:21:11,738 --> 00:21:15,577 From now on he will have to rely on your own speed. 187 00:21:24,216

greener... 205 00:23:47,305 --> 00:23:51,744 ...they mine almost everything the water they need from the plants they eat... 206 00:23:56,263 --> 00:23:59,342 ...and may not drink for several weeks. 207 00:24:01,941 --> 00:24:04,221 Thanks to incredible specialization 208 00:24:04,301 --> 00:24:07,781 red kangaroos live freely in the driest places in Australia 209 00:24:09,260 --> 00:24:12,620 But most marsupials need a constant source of water. 210 00:24:22,417 --> 00:24:25,777 Nimble wallabies — younger cousins of red kangaroos. 211 00:24:30,455 --> 00:24:34,215 They graze around oxbow rivers and streams in the north of Australia... 212 00:24:36,934 --> 00:24:40,093 ...and should periodically go to the water to drink. 213 00:24:50,891 --> 00:24:55,651 Salted crocodiles are waiting for those who is overcome by thirst. 214 00:25:02,009 --> 00:25:05,409 HEADLOW CREEK QUEENSLAND 215 00:25:08,327 --> 00:25:13,366 An ancient enemy that lives in these waters since the time of the dinosaurs. 216 00:25:50,278 --> 00:25:53,518 Universal vigilance and quick response... 217 00:25:55,517 --> 00:25:59,237 ...most often they allow the wallabies to escape. 218 00:26:05,755 --> 00:26:09,314 They had millions of years, to adapt to this danger. 219 00:26:10,395 --> 00:26:13,674 But now the marsupials are colliding with new threats 220 00:26:14,194 --> 00:26:16,033 and they are already difficult to overcome. 221 00:26:22,631 --> 00:26:27,990 Two hundred years ago people brought it new predators to Australia. 222 00:26:30,630 --> 00:26:35,109 Feral cats kill every year about 1.5 billion native animals. 223 00:26:39,189 --> 00:26:44,907 They played a decisive role 22 species of marsupials are at risk of extinction. 224 00:26:55,145 --> 00:26:58,864 Rabbit Bandicoot faces the same fate. 225 00:27:03,863 --> 00:27:08,102 Developed sense organs help a timid animal needs to navigate the night. 226 00:27:10,061 --> 00:27:15,420 The extended nose allows you to smell smells of seeds and fruits in the dark. 227 00:27:20,420 --> 00:27:23,099 Big ears help recognize the danger. 228 00:27:30,178 --> 00:27:33,297 But they are not able to escape from the cat. 229 00:27:38,256 --> 00:27:41,935 Bandicoots have already disappeared from 80% of its habitats. 230 00:27:43,534 --> 00:27:47,574 Some areas are now fenced special fences to keep cats out. 231 00:27:52,012 --> 00:27:55,332 And here the number of bandicoots is growing. 232 00:28:00,811 --> 00:28:05,729 But the main threat to marsupials control is even more difficult. 233 00:28:07,890 --> 00:28:09,089 In recent years 234 00:28:09,169 --> 00:28:14,408 wildfires in Australia have become more destructive than ever. 235 00:28:22,646 --> 00:28:27,405 Climate change causes one-off outbreaks became regular firestorms. 236 00:28:45,042 --> 00:28:49,960 Almost every year thousands of koalas and other marsupials die. 237 00:29:01,198 --> 00:29:02,357 After such fires 238 00:29:03,797 --> 00:29:06,357 hardly anything could survive. 239 00:29:18,635 --> 00:29:21,914 But eucalyptus trees are protected by thick bark. 240 00:29:23,433 --> 00:29:26,952 A few weeks later they turn green again. 241 00:29:32,591 --> 00:29:35,631 And soon all over Australia 242 00:29:36,630 --> 00:29:38,670 survivors return. 243 00:29:51,227 --> 00:29:53,547 With the onset of mating season among koalas 244 00:29:53,626 --> 00:29:56,706 usually sleepy animals are eager to set off. 245 00:30:04,064 --> 00:30:06,624 The roar of the male spreads for many kilometers... 246 00:30:19,701 --> 00:30:21,541 ...denoting its location... 247 00:30:23,820 --> 00:30:25,580 ...and showing its size. 248 00:30:29,139 --> 00:30:31,179 This is an invitation for females. 249 00:30:36,697 --> 00:30:38,018 There is an answer. 250 00:30:40,217 --> 00:30:42,056 But not the one he was waiting for. 251 00:30:47,336 --> 00:30:49,415 Disputes between males are rare... 252 00:30:54,334 --> 00:30:56,853 ...and they quickly escalate into a fight. 253 00:31:21,448 --> 00:31:23,088 The opponent has left. 254 00:31:26,567 --> 00:31:28,767 It's time to return to the search for the female. 255 00:31:39,244 --> 00:31:42,683 And finally his love call is heard. 256 00:31:55,161 --> 00:31:57,561 Although she is in no hurry to start a relationship. 257 00:32:02,399 --> 00:32:05,519 But when it comes to having children 258 00:32:06,078 --> 00:32:07,678 koalas don’t last long. 259 00:32:08,398 --> 00:32:11,118 She will give birth in just 35 days. 260 00:32:13,277 --> 00:32:14,837 If he gets his way. 261 00:32:22,755 --> 00:32:25,754 Such fast reproduction helped marsupials 262 00:32:25,834 --> 00:32:30,154 populate all corners of the continent even the most distant ones. 263 00:32:32,793 --> 00:32:36,312 WURUNURAN TROPICAL FOREST NORTH QUEENSLAND 264 00:32:37,712 --> 00:32:41,151 These are some of the highest trees in Australia. 265 00:32:42,591 --> 00:32:47,110 You may be surprised what is baby kangaroo doing here. 266 00:32:53,229 --> 00:32:55,748 But this is a tree kangaroo. 267 00:32:58,107 --> 00:33:01,507 His ancestors grew up on the plains 268 00:33:03,107 --> 00:33:08,225 but six million years ago one brave kangaroo climbed a tree. 269 00:33:09,105 --> 00:33:12,825 Slowly, but not so surely 270 00:33:12,904 --> 00:33:15,984 his descendants make treetops their home. 271 00:33:23,302 --> 00:33:25,542 Their forelimbs have become stronger 272 00:33:26,221 --> 00:33:27,821 claws are more curved 273 00:33:28,301 --> 00:33:31,181 and the hind legs are shorter than ordinary kangaroos. 274 00:33:37,979 --> 00:33:40,779 But evolution is a slow process. 275 00:33:41,698 --> 00:33:46,457 Against the background of other tree inhabitants they are not very elegant. 276 00:33:50,176 --> 00:33:51,616 And these are adults. 277 00:33:56,975 --> 00:34:01,654 After spending seven months in a bag, the baby begins to live independently. 278 00:34:09,733 --> 00:34:11,052 No experience 279 00:34:11,892 --> 00:34:13,172 no proper equipment 280 00:34:13,651 --> 00:34:15,171 and a height of seven floors. 281 00:34:30,968 --> 00:34:32,727 Mom can only watch. 282 00:35:16,918 --> 00:35:20,638 But the gods are kangaroos favor this baby. 283 00:35:24,996 --> 00:35:27,316 If his luck continues, 284 00:35:28,195 --> 00:35:31,595 he will spend another year under mother's supervision. 285 00:35:40,313 --> 00:35:45,592 Although the day comes when all marsupials you have to leave your cozy pocket. 286 00:35:59,229 --> 00:36:04,068 This cub is already 15 months old he made a huge leap forward. 287 00:36:06,867 --> 00:36:09,547 He spends his days in sparring with peers. 288 00:36:20,904 --> 00:36:23,183 Mom's bag is now occupied... 289 00:36:25,184 --> 00:36:26,143 ...his sister. 290 00:36:29,743 --> 00:36:33,582 She is only six months old and she hasn’t gone outside yet. 291 00:36:43,899 --> 00:36:46,898 But in this valley kangaroos are not the only ones who have babies. 292 00:36:54,337 --> 00:36:58,257 A flock of dingoes left their puppies to go hunting. 293 00:37:07,494 --> 00:37:13,253 Early settlers introduced dingoes to Australia about 3500 years ago. 294 00:37:19,572 --> 00:37:23,491 Since then they have become the worst enemies of the gray kangaroo. 295 00:37:33,928 --> 00:37:36,008 The kids rush for cover. 296 00:37:38,568 --> 00:37:40,287 But this little guy has nowhere to run. 297 00:37:49,325 --> 00:37:52,365 If he lags behind the pack, expect trouble. 298 00:38:23,959 --> 00:38:26,037 Dingo chased kangaroo 299 00:38:27,757 --> 00:38:29,397 searching for the slowest one. 300 00:38:52,152 --> 00:38:55,192 Mom with a heavy burden lags behind. 301 00:39:08,789 --> 00:39:10,268 Hunters are approaching. 302 00:39:42,782 --> 00:39:46,221 Less than half of all cubs survive to adulthood. 303 00:39:52,059 --> 00:39:54,859 But on the far edge of the valley 304 00:39:55,578 --> 00:39:58,938 the cub, mother and sister survived. 305 00:40:03,057 --> 00:40:05,137 Brave disposition 306 00:40:05,697 --> 00:40:07,976 amazing adaptability 307 00:40:08,536 --> 00:40:12,694 and, let's be honest, not much competition 308 00:40:13,575 --> 00:40:16,574 allowed marsupials of Australia overcome challenges 309 00:40:16,654 --> 00:40:18,814 this unmerciful land. 310 00:40:22,292 --> 00:40:25,652 But this wonderful crowd unusual animals 311 00:40:25,732 --> 00:40:29,532 difficulty adapting to the threat from new predators 312 00:40:31,571 --> 00:40:34,010 and to the chaos of climate change. 313 00:40:42,728 --> 00:40:45,968 But there are also those who fight for their future. 314 00:40:48,807 --> 00:40:53,646 All over Australia people devote their lives to saving… 315 00:40:55,806 --> 00:40:57,206 ...liberation... 316 00:41:02,284 --> 00:41:05,523 ...and protecting the marsupials most in need. 317 00:41:18,800 --> 00:41:22,120 And some types show amazing resilience. 318 00:41:23,400 --> 00:41:27,199 Giant kangaroos are thriving there are millions of them. 319 00:41:29,078 --> 00:41:30,918 Thanks to the power of the pack, 320 00:41:31,438 --> 00:41:33,597 one very devoted mother 321 00:41:34,638 --> 00:41:36,357 and her beautiful pocket 322 00:41:37,237 --> 00:41:39,676 this cub has started life successfully. 323 00:41:41,716 --> 00:41:43,156 Now it's time to grow up. 324 00:41:46,595 --> 00:41:47,754 And maybe 325 00:41:48,994 --> 00:41:50,354 one day he will be 326 00:41:51,314 --> 00:41:53,673 king of the kangaroos.
