them. 199 00:14:35,124 --> 00:14:36,959 After weeks of persistence, 200 00:14:37,251 --> 00:14:41,047 the team finally succeeded in filming a mother and calf. 201 00:14:42,590 --> 00:14:46,928 This mother's duty is to protect her calf while it grows quickly, 202 00:14:47,261 --> 00:14:51,101 before the long migration back to Arctic waters. 203 00:14:51,349 --> 00:14:53,643 As they travel between resting spots, 204 00:14:53,976 --> 00:14:57,772 the mother encourages her calf to breach repeatedly. 205 00:15:05,113 --> 00:15:07,907 It may look like just some fun splashing about, 206 00:15:08,314 --> 00:15:12,620 but it's key to helping the young calf build strength and muscles, 207 00:15:13,214 --> 00:15:15,540 that also develops their breath-holding abilities. 208 00:15:31,264 --> 00:15:34,308 The close bond between a mother whale and her calf 209 00:15:34,559 --> 00:15:37,478 provide our filmmakers with their first inroad 210 00:15:37,687 --> 00:15:39,647 into humpback whale society. 211 00:15:41,983 --> 00:15:44,861 Shallow coastal waters are the perfect sanctuary 212 00:15:45,403 --> 00:15:48,239 for a young calf to grow healthy and strong. 213 00:15:49,157 --> 00:15:52,452 Away from the dangers found in deeper, open waters. 214 00:15:56,539 --> 00:15:59,292 But it is also where it will soon be introduced 215 00:15:59,584 --> 00:16:01,461 to a greater whale community, 216 00:16:02,170 --> 00:16:03,713 a complex society... 217 00:16:04,797 --> 00:16:08,426 one our team is just beginning to understand. 218 00:16:13,681 --> 00:16:16,100 To truly understand a dolphin's world... 219 00:16:17,059 --> 00:16:21,063 the filmmakers need to journey to the very heart of their ocean home. 220 00:16:23,232 --> 00:16:25,526 To the foundations of the whole story. 221 00:16:26,694 --> 00:16:29,030 A delicately balanced ecosystem... 222 00:16:29,780 --> 00:16:33,618 that is sanctuary to millions of incredible supporting characters. 223 00:16:35,703 --> 00:16:37,163 A coral reef. 224 00:16:38,915 --> 00:16:41,792 Capturing the intricacies of this underwater world 225 00:16:42,335 --> 00:16:45,254 requires a great deal of technical camera skill 226 00:16:45,630 --> 00:16:48,966 and an exceptional eye for precision and detail. 227 00:16:51,177 --> 00:16:55,181 Cinematographer, Doug Anderson, is the perfect choice for such a job. 228 00:16:56,807 --> 00:16:59,352 DOUG: We wanted to make that experience of viewing the reef 229 00:16:59,519 --> 00:17:00,937 as immersive as possible. 230 00:17:01,103 --> 00:17:02,522 So, we tried different techniques... 231 00:17:02,813 --> 00:17:05,191 (CHUCKLES) ...as many things as we could think of 232 00:17:05,358 --> 00:17:08,486 to try and get more engaging photography. 233 00:17:10,905 --> 00:17:12,448 Uh, we used this underwater scooter, 234 00:17:12,615 --> 00:17:15,493 which is like a torpedo with a propeller on it, 235 00:17:15,868 --> 00:17:19,664 to get that feeling of the dolphin like gliding over the reef. 236 00:17:26,337 --> 00:17:29,131 We used a jib, which is like a camera on the end of an arm, 237 00:17:29,298 --> 00:17:31,717 which allowed us to make for very stable tracking moves 238 00:17:31,884 --> 00:17:34,220 over the coral reef, and really try and bring 239 00:17:34,387 --> 00:17:38,808 the character of the individual species that we wanted to include 240 00:17:39,175 --> 00:17:40,176 to the screen. 241 00:17:47,984 --> 00:17:50,898 Of all the underwater habitats on the planet, 242 00:17:51,153 --> 00:17:54,198 it's coral reefs that are the most overtly diverse. 243 00:17:55,491 --> 00:18:00,871 Just amazed by the color, and the life, and beauty in front of me. 244 00:18:02,121 --> 00:18:04,333 Absolutely breathtaking when you're there. 245 00:18:07,128 --> 00:18:09,505 Intense experiences of life. 246 00:18:18,848 --> 00:18:21,225 I like to think of a coral reef a bit like a city. 247 00:18:22,751 --> 00:18:24,826 The buildings are the corals. 248 00:18:27,398 --> 00:18:32,403 Those buildings provide homes and habitat for countless animals. 249 00:18:34,639 --> 00:18:37,617 Every animal that lives there is as important to each other 250 00:18:37,783 --> 00:18:39,035 as the next one. 251 00:18:40,494 --> 00:18:42,814 But there are very obvious animals in the coral reef 252 00:18:43,247 --> 00:18:44,957 that do very important jobs. 253 00:18:48,878 --> 00:18:51,464 NARRATOR: Doug wants to find key characters like these... 254 00:18:52,256 --> 00:18:54,675 to highlight critical links in the community. 255 00:18:56,132 --> 00:18:59,180 These handsome devils are the perfect example. 256 00:19:00,556 --> 00:19:01,974 Bumphead parrotfish. 257 00:19:04,610 --> 00:19:06,571 They are the local groundskeepers, 258 00:19:06,896 --> 00:19:10,207 clearing the reef of dead algae-covered coral. 259 00:19:15,404 --> 00:19:21,077 Recently, as our oceans have warmed, coral reefs have bleached and died. 260 00:19:22,078 --> 00:19:24,538 Reefs with parrotfish are quickly cleaned, 261 00:19:24,872 --> 00:19:28,501 and new coral can recolonize so the reef lives on. 262 00:19:30,044 --> 00:19:33,756 Reefs that have lost to their parrotfish rarely recover. 263 00:19:38,469 --> 00:19:41,430 Parrotfish are important to maintain the health of the reef... 264 00:19:42,598 --> 00:19:45,309 but Doug also discovers another important fish. 265 00:19:46,185 --> 00:19:49,522 The incredible, workaholic cleaner wrasse. 266 00:19:52,358 --> 00:19:55,361 DOUG: There are moments in the reef where it becomes very obvious 267 00:19:55,528 --> 00:19:57,738 how controlled and complex 268 00:19:57,947 --> 00:20:00,574 the relationships between the individual animals are. 269 00:20:01,027 --> 00:20:04,328 And one of them, for sure, is watching cleaner wrasse do their work. 270 00:20:06,330 --> 00:20:08,457 They do an enormously important job, 271 00:20:08,624 --> 00:20:11,043 and that's pick the parasites and dead skin 272 00:20:11,335 --> 00:20:12,628 and scales and everything else off. 273 00:20:13,003 --> 00:20:14,755 You know, they're getting right inside their mouths 274 00:20:14,922 --> 00:20:18,467 and inside their gills. They're constantly busy. 275 00:20:19,009 --> 00:20:21,804 They are just so fun to watch. 276 00:20:23,222 --> 00:20:24,849 And they, kind of, do this funny little dance 277 00:20:25,015 --> 00:20:26,434 to try and bring in business. 278 00:20:29,270 --> 00:20:31,397 Everyone comes to their cleaning stations. 279 00:20:32,264 --> 00:20:33,724 Cute little reef fish. 280 00:20:34,859 --> 00:20:36,736 And then you've got big predators. 281 00:20:37,903 --> 00:20:39,613 I tell you, it really takes your breath away 282 00:20:39,947 --> 00:20:41,031 when you watch a cleaner wrasse 283 00:20:41,240 --> 00:20:43,409 going into the mouth of a two-feet predator. 284 00:20:44,410 --> 00:20:46,120 There's just this convention on the reef, 285 00:20:46,203 --> 00:20:50,708 they do not touch the cleaner wrasse.

point of view, so we're going to have to light it. 401 00:28:07,144 --> 00:28:10,689 Most of the thought went into how we were going to logistically do it 402 00:28:10,856 --> 00:28:13,650 rather than the actual visuals of what it was going to look like. 403 00:28:13,984 --> 00:28:17,154 Then it really wasn't until I turned the lights on in the cave 404 00:28:17,321 --> 00:28:19,364 that I really got a sense of what sort of place it was. 405 00:28:20,949 --> 00:28:23,243 What I saw was a tomb. 406 00:28:24,036 --> 00:28:25,954 And on the ledges of these caverns 407 00:28:26,371 --> 00:28:28,957 lay the almost perfect skeletons of green turtles 408 00:28:29,249 --> 00:28:31,251 that had, over the years, died there. 409 00:28:40,469 --> 00:28:42,804 FEMALE DIVER: (SINGING) This

covered in fine sediment. 416 00:29:09,748 --> 00:29:12,334 Some believe this to be the powdered remains 417 00:29:12,834 --> 00:29:18,423 of thousands of turtle skeletons that have crumbled over countless ages. 418 00:29:18,966 --> 00:29:22,386 And one false move could cloud the entire cave, 419 00:29:22,636 --> 00:29:25,973 making it difficult for the crew to find their way out. 420 00:29:31,979 --> 00:29:34,314 After hours of meticulous setup, 421 00:29:35,274 --> 00:29:38,193 Doug starts to reveal the cave's haunting secrets 422 00:29:38,443 --> 00:29:42,990 from the

00:30:49,514 in the bottom of the cave, and then, you know, 436 00:30:49,681 --> 00:30:52,768 just imagining the turtles when they got lost in there 437 00:30:52,851 --> 00:30:55,062 and how scared and afraid they must've been. 438 00:30:59,232 --> 00:31:02,027 NARRATOR: To convey the broader story of this undersea world, 439 00:31:02,402 --> 00:31:05,489 the filmmakers wanted to balance these harsh realities 440 00:31:06,198 --> 00:31:08,533 with scenes of beauty and enchantment. 441 00:31:09,618 --> 00:31:10,911 And back in Hawaii, 442 00:31:11,328 --> 00:31:14,915 Didier has found the

has been monitoring their population recovery. 448 00:31:39,523 --> 00:31:42,776 JOE: Humpback whales in North Pacific were hunted to near extinction 449 00:31:42,968 --> 00:31:45,220 until they were protected in 1966. 450 00:31:45,695 --> 00:31:47,739 At that time, there were probably under a thousand whales 451 00:31:47,948 --> 00:31:48,949 that came to Hawaii. 452 00:31:49,574 --> 00:31:51,576 But now, 50 years later, 453 00:31:51,993 --> 00:31:56,123 there are maybe as many as 10,000 animals that visit the Hawaiian Islands. 454 00:31:57,749 --> 00:32:01,294 So, this day on the Luckey Strike, we were looking for a singer. 455 00:32:01,810 --> 00:32:04,423 To show that the whales communicate together, 456 00:32:04,589 --> 00:32:06,174 it's part of a community. 457 00:32:06,425 -->

third whale came, and they start to dance together. 478 00:34:20,392 --> 00:34:27,357 It's really a gift from nature to be first row in the theater. 479 00:34:33,613 --> 00:34:35,198 Diving with those

He's got to judge it. 598 00:42:06,088 --> 00:42:09,694 Just this, you know, wonderful image of them all racing down the wave. 599 00:42:09,861 --> 00:42:12,989 And then, as that wave breaks, he's going to accelerate us out of there. 600 00:42:13,448 --> 00:42:14,824 And it happened so quickly. 601 00:42:15,241 --> 00:42:17,702 (PARIS AND ROGER CHEERING) 602 00:42:21,664 --> 00:42:24,000 ROGER: It was really the shot that I was so hoping to get. 603 00:42:28,796 --> 00:42:31,174 This is so exhilarating.

you know, on it, 608 00:42:40,641 --> 00:42:42,894 exactly as we predicted, just jumping down the face, 609 00:42:43,352 --> 00:42:45,146 surfing the wave together, jumping out the back. 610 00:42:45,646 --> 00:42:47,523 ROGER: I mean, it's fantastic, yeah. 611 00:42:49,067 --> 00:42:52,779 NARRATOR: Our filmmakers have captured some incredible, dynamic scenes 612 00:42:53,045 --> 00:42:54,839 of dolphins letting loose. 613 00:42:56,866 --> 00:42:59,952 But a dolphin's daily life is not all fun and games. 614 00:43:02,914 --> 00:43:04,499 They also need to find food, 615 00:43:05,291 --> 00:43:07,251 not often found on the reef itself. 616 00:43:12,465 --> 00:43:15,343 And one of the most amazing dolphin feeding grounds 617 00:43:15,968 --> 00:43:17,178 is in the Bahamas. 618 00:43:18,805 --> 00:43:20,389 Onboard the Dolphin Dream, 619 00:43:20,657 --> 00:43:24,060 our Bahamian team are relying on skipper Scott Smith, 620 00:43:24,477 --> 00:43:27,980 a veteran dolphin finder, to take them to the action. 621 00:43:30,817 --> 00:43:32,944 Joining the crew for this portion of the story 622 00:43:33,469 --> 00:43:35,346 is cinematographer Paul Atkins 623 00:43:35,905 --> 00:43:40,576 a marine biologist and dolphin specialist who's filmed them all over the world. 624 00:43:51,170 --> 00:43:53,840 PAUL: I've been filming dolphins and whales for over 30 years. 625 00:43:54,924 --> 00:43:57,510 So, I've filmed bottlenose dolphins in the Bahamas before. 626 00:43:58,302 --> 00:44:01,139 I always look for an opportunity to go back. 627 00:44:02,306 --> 00:44:04,892 It's just always a thrill to get in the water 628 00:44:05,353 --> 00:44:07,353 and to see animals that I'm familiar with. 629 00:44:09,480 --> 00:44:12,024 And sometimes, I feel like they remember me, 630 00:44:12,275 --> 00:44:14,443 that they're coming up to me and saying hello. 631 00:44:15,695 --> 00:44:18,072 Eventually, when they stop paying attention to you, 632 00:44:18,239 --> 00:44:20,408 and then you become a part of their tribe. 633 00:44:20,575 --> 00:44:23,870 And it's an extraordinary experience when you can just travel with them 634 00:44:24,120 --> 00:44:26,080 and see what they do. 635 00:44:26,747 --> 00:44:28,207 (DOLPHINS WHISTLING) 636 00:44:28,457 --> 00:44:32,587 NARRATOR: Paul is here to capture dolphins hunting in a very special way. 637 00:44:35,673 --> 00:44:38,718 They use a type of sonar called echolocation, 638 00:44:39,635 --> 00:44:41,804 which works kind of like x-ray vision. 639 00:44:44,557 --> 00:44:46,726 (CLICKING) 640 00:44:47,685 --> 00:44:52,106 They emit a series of rapid-fire clicks that bounce off hidden objects, 641 00:44:53,107 --> 00:44:55,735 allowing them to locate food beneath the sand... 642 00:44:59,363 --> 00:45:01,490 food like razorfish. 643 00:45:06,787 --> 00:45:09,415 PAUL: When you're with a group of dolphins, 644 00:45:09,749 --> 00:45:13,169 you feel privileged to be witnessing their culture. 645 00:45:15,671 --> 00:45:20,509 Dolphins are one of the few animals besides humans and great apes 646 00:45:20,801 --> 00:45:23,095 that actually have been shown to have culture. 647 00:45:23,526 --> 00:45:26,641 And that culture is based on ways of finding food. 648 00:45:28,142 --> 00:45:29,518 (CLICKING) 649 00:45:37,485 --> 00:45:38,527 NARRATOR: Around the world, 650 00:45:38,945 --> 00:45:41,739 dolphins have developed different feeding strategies 651 00:45:42,156 --> 00:45:43,741 depending on their habitat. 652 00:45:45,201 --> 00:45:49,163 And some of them involve extraordinary levels of teamwork. 653 00:45:53,584 --> 00:45:56,212 These shallow tidal mudflats in Florida 654 00:45:56,472 --> 00:46:00,322 are a rich feeding ground for many marine and coastal animals. 655 00:46:02,009 --> 00:46:04,053 And with its great abundance of fish, 656 00:46:04,303 --> 00:46:09,100 it has given rise to a unique and spectacular dolphin hunting technique 657 00:46:09,809 --> 00:46:11,644 known as mud ringing. 658 00:46:17,525 --> 00:46:19,193 Scientist, Laura Engleby, 659 00:46:19,652 --> 00:46:23,781 has brought cinematographer Jamie McPherson onto these tidal flats 660 00:46:24,031 --> 00:46:26,617 in search of this remarkable phenomenon. 661 00:46:29,870 --> 00:46:32,290 For Jamie, it may not be as heart-stopping 662 00:46:32,456 --> 00:46:34,792 as filming dolphins surfing the big waves, 663 00:46:35,501 --> 00:46:37,086 but it is just as difficult. 664 00:46:41,716 --> 00:46:44,010 -JAMIE: Oh, damn it. -(LAURA LAUGHS) 665 00:46:44,337 --> 00:46:46,887 JAMIE: From the boat, it's tricky because you have to work out where they are. 666 00:46:47,346 --> 00:46:48,931 The camera's right on sea level. 667 00:46:49,482 --> 00:46:51,067 You only see them when they surface. 668 00:46:51,267 --> 00:46:52,476 So, you see the fins occasionally. 669 00:46:52,727 --> 00:46:54,603 You're trying to work out where they're going to go. 670 00:46:54,870 --> 00:46:56,247 It's very hard to coordinate that. 671 00:46:56,856 --> 00:46:59,275 It's very tricky to be in the right place at the right time. 672 00:47:02,361 --> 00:47:05,239 NARRATOR: Suddenly, the dolphins look like they are teaming up 673 00:47:05,614 --> 00:47:07,033 and coordinating their efforts. 674 00:47:07,455 --> 00:47:08,605 WOMAN: No, Jamie, now they're to the right. 675 00:47:08,951 --> 00:47:10,619 -To the right. -JAMIE: Coming where? 676 00:47:10,703 --> 00:47:12,079 -WOMAN 1: To your right. -WOMAN 2: Right. 677 00:47:12,280 --> 00:47:14,105 WOMAN 1: See them? 678 00:47:15,458 --> 00:47:16,917 NARRATOR: They've started to hunt. 679 00:47:21,063 --> 00:47:24,108 Jamie zeroes in on the action with his zoom lens. 680 00:47:29,764 --> 00:47:31,223 JAMIE: Well, you see a lot of splashing. 681 00:47:33,601 --> 00:47:36,687 They don't put their heads up to catch the fish until the very last second. 682 00:47:37,396 --> 00:47:40,232 The dolphins still
