0:00:02 > 0:00:03This is Madagascar.
0:00:03 > 0:00:07It's a vast island in the Indian Ocean off the east coast of Africa,
0:00:07 > 0:00:08and it's home to some of the most unique
0:00:08 > 0:00:11and rare creatures on the planet.
0:00:11 > 0:00:15Incredibly, 80% of the wildlife here exists nowhere else on Earth.
0:00:15 > 0:00:17HOWLING
0:00:18 > 0:00:21But it's a paradise under threat.
0:00:26 > 0:00:30So I've sent eight ordinary kids from the UK
0:00:30 > 0:00:33to have the deadly adventure of their lives.
0:00:33 > 0:00:38They'll face the toughest challenges,
0:00:38 > 0:00:42and discover for themselves how to save this lost world
0:00:42 > 0:00:44before it's too late.
0:01:20 > 0:01:25Last time, our group's challenge was to track down fossa in the wild.
0:01:25 > 0:01:26Perfect.
0:01:26 > 0:01:29And they saw for themselves how plant and animal invaders...
0:01:29 > 0:01:32- Oh.- He's got the meat. He's taken the meat.- Oh.
0:01:32 > 0:01:35..can affect the wildlife that lives here.
0:01:37 > 0:01:40For their next set of challenges, they're going to
0:01:40 > 0:01:42a location off the northwest coast of Madagascar...
0:01:45 > 0:01:47..to Ile Sainte-Marie,
0:01:47 > 0:01:51a small island known for pirate legends,
0:01:51 > 0:01:57tropical beaches and its biggest tourist attraction, humpback whales.
0:02:00 > 0:02:03The gang are going to check out their tropical paradise.
0:02:05 > 0:02:07It's like a paradise beach.
0:02:11 > 0:02:15- Is it cold?- It's not cold, actually. - It's nice.- It's all right.
0:02:15 > 0:02:17And compared to, like, cos we've been camping for so long
0:02:17 > 0:02:21- and we've come here, it's really nice.- ALL: Yeah.
0:02:21 > 0:02:26I think it's like gone from rough area to absolutely luxury area.
0:02:26 > 0:02:28And if you think of it, this place
0:02:28 > 0:02:30is like the island of the actual movie Madagascar,
0:02:30 > 0:02:33like, there's just like sea and loads and loads of trees...
0:02:33 > 0:02:35- You see, like, a giraffe and... - Yeah, giraffe and hippo.
0:02:38 > 0:02:42Thousands of people come here a year to see the whales.
0:02:42 > 0:02:45Raina has strong views about the negative impact tourists
0:02:45 > 0:02:47can have on a place.
0:02:47 > 0:02:50I personally think that this island is much better without tourism.
0:02:50 > 0:02:53Because I think the tourists ruin a lot of the natural
0:02:53 > 0:02:58beauty of this island, cos if there was a lot of big attractions and
0:02:58 > 0:03:01things crowding this island, I don't think people would want to come.
0:03:02 > 0:03:05And it's finding out about this impact that's
0:03:05 > 0:03:09the new challenge for our deadly explorers.
0:03:09 > 0:03:11Can they find out how tourism could actually help
0:03:11 > 0:03:13protect the wildlife here?
0:03:15 > 0:03:18The best place to start is to do just what all the tourists
0:03:18 > 0:03:21come here to do - to go whale watching.
0:03:24 > 0:03:28Whale watching is a huge industry globally
0:03:28 > 0:03:32and Ile Sainte-Marie is one of the best places in the world to do it.
0:03:33 > 0:03:37So our team are in for a real treat.
0:03:37 > 0:03:40And one of the party is particularly excited.
0:03:40 > 0:03:44They're one of my favourite animals.
0:03:44 > 0:03:46Whoa! I'm flying!
0:03:46 > 0:03:49The journey there's quite bumpy.
0:03:50 > 0:03:53- Are you all right?- I think there's some over there.
0:03:53 > 0:03:55And they don't have to go very far
0:03:55 > 0:03:57before they get their first encounter.
0:03:57 > 0:03:58Oh, my!
0:04:00 > 0:04:03- Look at it! - Wow, that's quite close.
0:04:20 > 0:04:22Oh, wow.
0:04:27 > 0:04:29Oh, my!
0:04:34 > 0:04:37- Oh, wow!- Oh, that was cool!
0:04:39 > 0:04:40I can't believe it.
0:04:44 > 0:04:45Cool.
0:04:47 > 0:04:49Whoa! That's close.
0:04:52 > 0:04:55That was very close.
0:04:55 > 0:04:57Whilst Jamie's pretty vocal about her experience...
0:04:59 > 0:05:02This is the best day of the trip for me, definitely.
0:05:02 > 0:05:05..there's another member of the team that's almost speechless.
0:05:09 > 0:05:12Eilidh's greatest passion is for the marine environment.
0:05:16 > 0:05:20I've always been completely obsessed with the ocean.
0:05:20 > 0:05:22I would see people with the scuba tanks on their back,
0:05:22 > 0:05:25going diving, and I'll think, "That's what I want to do when I'm older."
0:05:27 > 0:05:29That's when I decided that I want to be a marine biologist.
0:05:29 > 0:05:31So I love diving, reading and writing
0:05:31 > 0:05:34and, basically, anything to do with the sea.
0:05:36 > 0:05:38Back on the water, she's still on a high.
0:05:39 > 0:05:43When I saw the whales I was like, I was crying. I was.
0:05:43 > 0:05:48The best moments of my life have either been by the water,
0:05:48 > 0:05:50on the water or in the water.
0:05:50 > 0:05:54So this is one of the best moments of my life.
0:05:58 > 0:06:01But what makes this place so special?
0:06:01 > 0:06:05Every summer, humpback whales migrate here from the Antarctic.
0:06:05 > 0:06:07Their destination is the narrow channel between
0:06:07 > 0:06:10Ile Sainte-Marie and the mainland.
0:06:11 > 0:06:14These calm, warm waters are ideal for humpback whales
0:06:14 > 0:06:16to give birth.
0:06:16 > 0:06:20So this place is a massive nursery for these ocean giants.
0:06:20 > 0:06:24And around the shores of Madagascar, the numbers of whales that
0:06:24 > 0:06:27migrate here is in their thousands.
0:06:27 > 0:06:30So they're not passing by, but staying here to look after
0:06:30 > 0:06:34their newborn calves, and this in turn attracts the big males
0:06:34 > 0:06:37who want to come and show off to the new mothers -
0:06:37 > 0:06:40all making for some really exciting encounters.
0:06:45 > 0:06:50It seems like one of the humpback whales is just on its back,
0:06:50 > 0:06:52kicking its tailfin around.
0:06:53 > 0:06:57Wow, it makes quite a loud smack.
0:07:01 > 0:07:06That's a way of possibly calling. Such a loud noise through the water.
0:07:07 > 0:07:10Tail-slapping is one of the ways that the males warn
0:07:10 > 0:07:12other males of their presence.
0:07:13 > 0:07:17The sound travels for over five miles underwater.
0:07:17 > 0:07:20But it's not the only way that humpbacks communicate.
0:07:20 > 0:07:22They're also very vocal animals.
0:07:22 > 0:07:26But you need some specialist kit to hear that.
0:07:26 > 0:07:29What we're doing is we're putting an underwater microphone
0:07:29 > 0:07:33under the water to see if we can hear the whales singing.
0:07:33 > 0:07:36It'll be the males who are searching for females.
0:07:36 > 0:07:39WHALES SING
0:07:41 > 0:07:44I can hear the whales singing.
0:07:44 > 0:07:47It's the males, they want to attract the females.
0:07:53 > 0:07:56I've never heard a whale singing before.
0:07:56 > 0:07:59It's actually quite emotional, cos I've never actually heard one
0:07:59 > 0:08:02and their song is actually really beautiful.
0:08:03 > 0:08:05It's like, "Lal-lal eee-ooo."
0:08:09 > 0:08:13It's no wonder that whale watching is so popular with tourists.
0:08:15 > 0:08:17'On the way back, they begin to think about how whales can
0:08:17 > 0:08:19'benefit the local people.'
0:08:21 > 0:08:25Humpback whales can't be found everywhere and they're a very
0:08:25 > 0:08:29important animal, so tourists want to come and see them.
0:08:29 > 0:08:34If you look around the town, there's just signs everywhere
0:08:34 > 0:08:38advertising the whales, and I think the whales mean a lot
0:08:38 > 0:08:40to the people of Sainte-Marie,
0:08:40 > 0:08:43maybe because it brings them in money and business.
0:08:44 > 0:08:47'But Oak spots a real problem.'
0:08:47 > 0:08:51Too many tourists can wreck and destroy the whole
0:08:51 > 0:08:55point that the tourists are there. So, by regulating it
0:08:55 > 0:09:01and protecting it, you can prolong your tourist industry for longer but
0:09:01 > 0:09:06you've also helped save the thing that your tourists are coming for.
0:09:06 > 0:09:09Whale watching is well regulated here.
0:09:09 > 0:09:14And by bringing tourists in, it can benefit the whole island.
0:09:14 > 0:09:18On shore, there are other projects that generate an income from whales.
0:09:20 > 0:09:23Some of the gang are going to find out about one that benefits
0:09:23 > 0:09:26the whales, tourists and the local people.
0:09:26 > 0:09:31'They meet Maria, a marine biologist.
0:09:31 > 0:09:35'She works for CetaMada, a local conservation organisation.
0:09:35 > 0:09:38'Passionate about whales, she's keen to show them
0:09:38 > 0:09:40'how their project works.'
0:09:40 > 0:09:45Are you ready? OK. Let's go. So the boys come in this room
0:09:45 > 0:09:49and the girls will stay with our artisans on the back, OK?
0:09:49 > 0:09:53Charlie and Yoran's task is to help make whale cushions
0:09:53 > 0:09:55that will be sold in the shop to tourists.
0:09:57 > 0:10:02- Where are the artisans? Nadine.- Bonjour.- Bonjour.
0:10:02 > 0:10:07So are you ready to stuff some whales and to make it?
0:10:07 > 0:10:10- Yep. Definitely.- Good.
0:10:10 > 0:10:13We're just stuffing some broken up foam into the whale
0:10:13 > 0:10:15to make it into a pillow.
0:10:16 > 0:10:20She makes five of these big ones in one day
0:10:20 > 0:10:24and I reckon I could make about five of these little ones, maybe.
0:10:24 > 0:10:27- No, you couldn't. - That one, actually, no.
0:10:27 > 0:10:30I could make about two of these little ones in one day, I reckon,
0:10:30 > 0:10:33if I knew how to sew...properly.
0:10:33 > 0:10:37- Can you sew, like?- I can do that!
0:10:37 > 0:10:41In, out, in, out. Can't start it, can't finish it.
0:10:41 > 0:10:45Just outside the centre, Gwen and Eilidh are getting on well.
0:10:45 > 0:10:49Their task is to make jewellery out of dried coconut.
0:10:49 > 0:10:52And we've got to sand down these tails
0:10:52 > 0:10:55but I'm afraid that I'll do something wrong.
0:10:55 > 0:11:00These tails are made out of coconut shell, which is really good, cos
0:11:00 > 0:11:03it's sustainable cos you don't have to chop down any trees, you can just
0:11:03 > 0:11:07pick up a coconut off the ground, cut it open and use the shell.
0:11:09 > 0:11:11If we had to do the whole thing, we could probably
0:11:11 > 0:11:13make about four together, couldn't we?
0:11:15 > 0:11:19Maybe not even that, cos this sanding's taking quite a while.
0:11:19 > 0:11:24It's great that they can make these products and they're sustainable
0:11:24 > 0:11:27and help the environment and they earn money at the same time.
0:11:27 > 0:11:29Having stuffed their cushions,
0:11:29 > 0:11:33Charlie and Yoran are getting to know a project worker called Sophia.
0:11:33 > 0:11:35How long have you worked here?
0:11:37 > 0:11:41TRANSLATOR SPEAKS FRENCH
0:11:41 > 0:11:42SOPHIA ANSWERS IN FRENCH
0:11:42 > 0:11:46- Three years.- Right. - She likes to teach,
0:11:46 > 0:11:49she likes people to learn, like she's teaching you.
0:11:49 > 0:11:53- Good teacher.- Merci.- Thank you.
0:11:55 > 0:11:58Maria's keen to share how this project helps the whales.
0:11:58 > 0:12:03So our idea in the future is that people like these artisans
0:12:03 > 0:12:08care more about the whales after working with us,
0:12:08 > 0:12:13so they will see that tourists buy these kind of things because
0:12:13 > 0:12:18whales exist, so they will care about the whales existing and coming to
0:12:18 > 0:12:24Madagascar, and this is the link that we do between economy and, of course,
0:12:24 > 0:12:28the conservation of marine mammals, the conservation of the whales.
0:12:28 > 0:12:31Good? Cool.
0:12:31 > 0:12:36Yeah, this is the first thing out of fabric that I've made and obviously,
0:12:36 > 0:12:40I didn't even make, I just stuffed it and then sewed up the hole.
0:12:40 > 0:12:42So hopefully, it will sell.
0:12:44 > 0:12:46The girls are finishing up, too.
0:12:46 > 0:12:51I had no idea that you could make jewellery out of so much stuff.
0:12:51 > 0:12:55Everything's handmade, you know, there's no tools or anything
0:12:55 > 0:12:58involved, so I reckon they do make quite a good profit from this.
0:13:00 > 0:13:04We're done...just about.
0:13:04 > 0:13:07Well, for a first go, I don't think we did half bad.
0:13:09 > 0:13:10Whale tail.
0:13:13 > 0:13:16Charlie can see how tourism can help local people.
0:13:16 > 0:13:19All the products get sold here for souvenirs,
0:13:19 > 0:13:22like when people come in from having their boat trip.
0:13:22 > 0:13:25It's giving the people that make them a job.
0:13:25 > 0:13:28Obviously, any money that's being made selling these
0:13:28 > 0:13:31helps save the whales, so I just think it's a great cause
0:13:31 > 0:13:34and it was really good fun just to be part of it.
0:13:34 > 0:13:37It seems generating an income from wildlife is one
0:13:37 > 0:13:39way that helps protect it.
0:13:40 > 0:13:43But tourists brought here for whale watching
0:13:43 > 0:13:45don't just buy whale souvenirs.
0:13:50 > 0:13:53Some of the gang are going to find out another way
0:13:53 > 0:13:56that tourists provide an income to the island community.
0:14:01 > 0:14:05We're going to an area where they produce vanilla
0:14:05 > 0:14:08and we're going to see the process of how they make it,
0:14:08 > 0:14:11from picking it from the trees or the bushes or wherever
0:14:11 > 0:14:16it comes from, to putting it into packs and selling it on the streets.
0:14:17 > 0:14:2080% of the world's vanilla comes from Madagascar.
0:14:20 > 0:14:23It's an ingredient found in ice cream, yoghurt and chocolate.
0:14:25 > 0:14:28It can only be grown in tropical environments, and here
0:14:28 > 0:14:33in Ile Sainte-Marie, it can be a huge part of this family's income.
0:14:33 > 0:14:35To pick them, you have to break the branch that they're on cos
0:14:35 > 0:14:39it's more better than taking each one off.
0:14:42 > 0:14:45I've got four pods of vanilla.
0:14:45 > 0:14:50But these are quite large to the finished product
0:14:50 > 0:14:53and, obviously, a different colour.
0:14:53 > 0:14:56Jamie and Okechukwu find out a bit about the process.
0:14:58 > 0:15:00Yeah, they boil it, I was right.
0:15:02 > 0:15:06So we've just picked off some vanilla pods from the nearby trees
0:15:06 > 0:15:09and now she's been boiling some water,
0:15:09 > 0:15:12so I think that we're going to put the vanilla pods in the water.
0:15:12 > 0:15:15You have to boil the vanilla at 40 degrees
0:15:15 > 0:15:20and then you wrap it in a blanket for two days, and then every day
0:15:20 > 0:15:24then you dry it out in the sun for an hour for two months.
0:15:28 > 0:15:31In its rawest form, they look like green beans, but after
0:15:31 > 0:15:35time in the sun, they intensify in flavour and look very different.
0:15:38 > 0:15:41The gang begin to see how vanilla is another
0:15:41 > 0:15:43opportunity to make money from tourists.
0:15:45 > 0:15:47I think it would sell because people here want to buy
0:15:47 > 0:15:50- something that's like...- Significant to Madagascar.- ..Endemic.
0:15:50 > 0:15:53Yeah, sort of endemic to Madagascar, so that they have the vibe that,
0:15:53 > 0:15:56"Yes, I bought something from Madagascar that you can only
0:15:56 > 0:15:59"get in Madagascar." It'll make you feel more special by buying it.
0:16:01 > 0:16:04And buying vanilla might make you feel special,
0:16:04 > 0:16:07but selling it to tourists is a different matter entirely.
0:16:10 > 0:16:12The team's challenge is to head in to the local town
0:16:12 > 0:16:15and to find out for themselves what it's like to try
0:16:15 > 0:16:17and sell vanilla to tourists.
0:16:17 > 0:16:21- I need something to support it. - I'm going to spread it out.- 20,000.
0:16:21 > 0:16:24After setting up their stall, they're ready to make sales.
0:16:31 > 0:16:33It's not the rush they were hoping for.
0:16:37 > 0:16:40I don't understand how local people manage to sell them
0:16:40 > 0:16:42to tourists when no-one wants to buy any.
0:16:42 > 0:16:45I could always walk around and, like, ask.
0:16:45 > 0:16:47I'm trying to look for any oncoming tourists
0:16:47 > 0:16:49or people who might want to buy.
0:16:49 > 0:16:53You've just got to say, "Please, this is 15,000 ariary,
0:16:53 > 0:16:54"would you like to buy some?"
0:16:57 > 0:17:00Excuse me, could I interest you in any vanilla?
0:17:00 > 0:17:04I am sorry, but I have already my...
0:17:04 > 0:17:08You already bought some? I tried. Can't do it.
0:17:08 > 0:17:12They take to the streets to try and make a sale.
0:17:12 > 0:17:14- Bonjour.- Buongiorno.
0:17:16 > 0:17:18OK, that was a quick "No."
0:17:18 > 0:17:20We need to sell something.
0:17:20 > 0:17:22Grr!
0:17:22 > 0:17:26Bonjour. Would you be interested in buying vanilla?
0:17:26 > 0:17:30SPEAKS FRENCH
0:17:30 > 0:17:33Nobody's going to buy any, cos nobody's a tourist.
0:17:36 > 0:17:40- Oh, there's tourists! Would you like any vanilla?- No, merci.
0:17:40 > 0:17:44And after an hour, Jamie starts to feel the pressure.
0:17:44 > 0:17:47Buy some! Please!
0:17:47 > 0:17:51I need to find more people! Grr!
0:17:51 > 0:17:53No, thank you.
0:17:53 > 0:17:59No. 10,000 ariary. Vanille!
0:17:59 > 0:18:01Meanwhile, on their stall, Raina and Okechukwu
0:18:01 > 0:18:03get a grilling about their product.
0:18:03 > 0:18:08- How much is it then, the vanilla? - So this is 25,000 for a large.
0:18:08 > 0:18:11The big one and, then we're selling the little ones for 20,000.
0:18:11 > 0:18:13OK, so you helped them to pick it?
0:18:13 > 0:18:15Not this one in particular but we did,
0:18:15 > 0:18:18we learnt all about the process and everything.
0:18:18 > 0:18:21- Oh, well done, anyway. Have you sold any yet?- No.
0:18:21 > 0:18:23They get their sale.
0:18:23 > 0:18:25- Are we there?- Yep.
0:18:25 > 0:18:29- Great, OK. Well done. Well done, guys.- Thank you very much.
0:18:29 > 0:18:31And Raina begins to see that making
0:18:31 > 0:18:35and selling vanilla is not a get-rich-quick scheme.
0:18:35 > 0:18:38We've only been doing this like an hour or so
0:18:38 > 0:18:41and we've got only one customer. And there's people who have to do
0:18:41 > 0:18:44this every single day and that's what they rely on, so if that day
0:18:44 > 0:18:47they don't get any customers, they can't buy the things that they need.
0:18:47 > 0:18:49So it must be really frustrating for them.
0:18:50 > 0:18:53Jamie finally gets a sale, too.
0:18:53 > 0:18:55Merci. Merci beaucoup.
0:18:57 > 0:18:59I think we've done well, actually.
0:18:59 > 0:19:04- It's been good, well done. - Yeah, I think so.- Woo, yeah!
0:19:04 > 0:19:08And Oak also begins to see how crucial tourists are.
0:19:08 > 0:19:12Personally, I've learnt how hard it is to be in this business
0:19:12 > 0:19:16and have to sell your own produce to make a living,
0:19:16 > 0:19:19and tourism is their only way forward.
0:19:19 > 0:19:23And I thought, being kind of a tourist ourselves, it'd be easier
0:19:23 > 0:19:24but it obviously wasn't.
0:19:24 > 0:19:27- Hey, guys.- Oh, hi.- Packing up?
0:19:27 > 0:19:30So what do you think you've kind of taken from this experience?
0:19:30 > 0:19:34- That it's hard.- It's really hard.
0:19:34 > 0:19:36Like, they don't want to buy stuff. They just go, "No."
0:19:36 > 0:19:39We're stubborn, tourists.
0:19:39 > 0:19:42Well done, you guys. High five.
0:19:42 > 0:19:46I think the woman would be happy. You guys?
0:19:51 > 0:19:54That night, the whole team get a chance to relax
0:19:54 > 0:19:56and then think about their time here.
0:19:56 > 0:20:00The best day of my life, we went whale watching,
0:20:00 > 0:20:03humpback whale watching, they're my favourite animals now.
0:20:03 > 0:20:06Watching those whales breach and watching them being so close,
0:20:06 > 0:20:08oh, it was amazing!
0:20:08 > 0:20:13Today, we went and stuffed animals for cushions and that,
0:20:13 > 0:20:15and one of the women said, I asked her, "How long have you been
0:20:15 > 0:20:18"working here?" and she was like, "Three years,"
0:20:18 > 0:20:20and she said it's not to do with the money,
0:20:20 > 0:20:25it's to do with the fact that I'm now helping whales and making money.
0:20:25 > 0:20:28I realised how hard it was to actually sell vanilla because you
0:20:28 > 0:20:30think a lot of the tourists will just go,
0:20:30 > 0:20:33"Oh, yeah, vanilla, Madagascar, buy some,
0:20:33 > 0:20:36"cos it's obviously the best quality." But nowadays, tourists
0:20:36 > 0:20:39don't really want to be bothered so it's much harder than I expected.
0:20:39 > 0:20:43Shone out everywhere we've been, that obviously, you can't
0:20:43 > 0:20:45do conservation without getting the local people involved.
0:20:45 > 0:20:48The group see that both people
0:20:48 > 0:20:51and wildlife need to benefit from tourism.
0:20:57 > 0:20:59But tourists don't just bring in money,
0:20:59 > 0:21:02they can actually help with science, too.
0:21:02 > 0:21:04The team meet back up with Maria,
0:21:04 > 0:21:08who has the perfect solution for tourists wanting to see whales.
0:21:08 > 0:21:10Today, it's a special trip with you.
0:21:10 > 0:21:16OK, you are going to be looking for scientific data.
0:21:16 > 0:21:20'She gets the tourists to help her monitor the whale population.
0:21:20 > 0:21:25'She can then try and identify which animals are returning each year.'
0:21:25 > 0:21:30And my friend is going to be the observer, so you need to
0:21:30 > 0:21:33relate everything that you see and she's going to write it.
0:21:33 > 0:21:36Yeah, we've just all been given our roles
0:21:36 > 0:21:42and I'm on the camera. Yoran's got the GPS, Gwen's got to tell Raina
0:21:42 > 0:21:44everything she sees, so, the whale's actions,
0:21:44 > 0:21:47and Raina's got to record it. So we've all got our jobs.
0:21:47 > 0:21:51And hopefully, we'll find some to do it with.
0:21:51 > 0:21:54Heading out to sea, their job is to get a visual identification
0:21:54 > 0:21:55of whales in the area.
0:21:58 > 0:22:01And the best way of doing that is to take a picture of their tale,
0:22:01 > 0:22:02known as the flukes.
0:22:04 > 0:22:05Whoa!
0:22:08 > 0:22:11But they don't have to go very far.
0:22:11 > 0:22:12There!
0:22:19 > 0:22:21We've just found two of the whales.
0:22:23 > 0:22:26Getting a photo of a whale fluke is like taking
0:22:26 > 0:22:27somebody's fingerprint.
0:22:27 > 0:22:30There, there, there.
0:22:30 > 0:22:34It's important to get in the right position, as Charlie
0:22:34 > 0:22:36only has a couple of seconds to get the shots.
0:22:42 > 0:22:45There, there, there! Oh, my God, there.
0:22:51 > 0:22:54Woo! Oh, yes! Look at that!
0:23:01 > 0:23:04Quickly, quickly, Charlie.
0:23:05 > 0:23:07- Great!- Did you get him, Charlie?
0:23:07 > 0:23:10I think you did. You was like, "Click, click, click, click, click."
0:23:10 > 0:23:14Look, look! Look, look! Woo!
0:23:14 > 0:23:16Just when you asked for it, you have it.
0:23:18 > 0:23:19That was wicked.
0:23:19 > 0:23:23Because we thought there was only one when we started following it.
0:23:23 > 0:23:27Obviously, when we got closer, then we realised it was a mother and calf
0:23:27 > 0:23:31and then we realised there was an escort too, so there was three.
0:23:31 > 0:23:34But for Raina, it's not quite as exciting.
0:23:36 > 0:23:40- Raina, how you feeling?- Sick. - Fair enough.
0:23:42 > 0:23:44To complete their challenge,
0:23:44 > 0:23:47they get back to shore and add their photos to the CetaMada database.
0:23:55 > 0:23:58Somebody is going to tell me what is here?
0:23:58 > 0:24:00- Are these the ones that Charlie took?- Yes.
0:24:00 > 0:24:04- Pretty good. - So. Cool pictures, huh?
0:24:04 > 0:24:08So here, for example, we have the left dorsal of the mother, OK?
0:24:08 > 0:24:13We have the fluke of the mother, that's a good picture.
0:24:13 > 0:24:18We can see the characteristics, the pattern, the different colour parts.
0:24:18 > 0:24:22So we have a quite good photo ID in that.
0:24:22 > 0:24:25Charlie's pictures will help future research
0:24:25 > 0:24:28and also be a part of tonight's game.
0:24:30 > 0:24:34As the sun sets, all our deadly adventurers regroup
0:24:34 > 0:24:37to play this game with Maria.
0:24:37 > 0:24:39It's whale bingo.
0:24:39 > 0:24:42Each player is given a booklet of different whale flukes that
0:24:42 > 0:24:44have been taken over the years.
0:24:46 > 0:24:50If they can match one from their book to Charlie's photo onscreen,
0:24:50 > 0:24:54then they know that the whale is one that's been here before.
0:24:54 > 0:24:56Is it easy?
0:24:56 > 0:24:58Been going through for so long.
0:24:58 > 0:25:01Gwen is as keen as ever to win.
0:25:01 > 0:25:05I've been all the way through the book, it's not there. Oh, wait.
0:25:06 > 0:25:10But not the spot just in the middle, close to the notch.
0:25:11 > 0:25:15Right here, a black one. And it's a very big notch.
0:25:20 > 0:25:22There's so many pictures, how are you supposed to get through
0:25:22 > 0:25:25a book like that with one picture? You just flick through them.
0:25:25 > 0:25:29- Bingo!- Where? - I think. Possibly, maybe.
0:25:29 > 0:25:34- Possible.- Maybe.- Maybe. - The line.- Oh, yes.
0:25:34 > 0:25:38- This line here. It's got that spot. - That spot?- The bit in the middle.
0:25:38 > 0:25:42I want you to come in front and to tell us that, please.
0:25:45 > 0:25:47OK. Show yours here on the light...
0:25:48 > 0:25:51..and tell us the line that you saw.
0:25:51 > 0:25:55- The line's there and then. - There is no line over there.
0:25:55 > 0:25:58Then look, there's little dash there. That little dash there.
0:25:58 > 0:26:02Then some of these barnacle prints are the same, as well.
0:26:02 > 0:26:05And it's got, like, you see these there, they're in there.
0:26:05 > 0:26:09They are still there. We don't use them to identify.
0:26:09 > 0:26:13It's also the same one, so he deserves a big clap.
0:26:13 > 0:26:14APPLAUSE
0:26:16 > 0:26:17And of course...
0:26:17 > 0:26:19Grr!
0:26:19 > 0:26:24..to remember that you win the bingo fluke, huh? A big clap.
0:26:30 > 0:26:35Very, very, very good eyes. OK. You are not playing.
0:26:35 > 0:26:38I think I might call it Charlie, cos Charlie did take that picture.
0:26:40 > 0:26:44The team's photos will contribute to Maria's future research.
0:26:44 > 0:26:48And it seems tourists are great for wildlife, as they not only
0:26:48 > 0:26:52help monitor the animals, they also bring in money for local people.
0:26:54 > 0:26:57And with tourism well managed here, more whales are returning to
0:26:57 > 0:27:00this island and the outlook for them is looking good.
0:27:08 > 0:27:11Next time, our deadly adventurers are going to find out
0:27:11 > 0:27:15why the precious coral reefs around the island are under threat.
0:27:15 > 0:27:19It was all sort of dull and that's really, really sad.
0:27:19 > 0:27:22And there's tension among the group as they realise how
0:27:22 > 0:27:25this affects the people that live here.
0:27:25 > 0:27:27But you don't have to, it's just a suggestion.
