0:01:20 > 0:01:24I'm here at the port in Santa Cruz to meet Kai and his dad, Robbie.

0:01:24 > 0:01:27They're going to be getting ready for our big adventure,

0:01:27 > 0:01:28so let's try and find them.

0:01:36 > 0:01:39- Hola, Kai.- Hi. - How are you?- Good.

0:01:39 > 0:01:42- Hi, and you must be Robbie. - Hello.- Hi. Lovely to meet you.

0:01:42 > 0:01:45- Are you excited?- Yes. And you?- I cannot wait.

0:01:45 > 0:01:47- Where's our boat?- In the bay.

0:01:47 > 0:01:50- Shall we go?- Yes.- OK.

0:01:50 > 0:01:52- Gracias.- Life jacket.

0:02:07 > 0:02:10- So, Kai, where are we off to? - Here. Fernandina Island.

0:02:10 > 0:02:12Oh, I've heard a lot about it.

0:02:12 > 0:02:15- It's very special, isn't it? - It's the youngest.

0:02:15 > 0:02:17In all of the Galapagos Islands?

0:02:17 > 0:02:19- Yes.- But there's also something else special about it.

0:02:19 > 0:02:21- What is it?- It's a volcano.

0:02:21 > 0:02:23That's right. It is.

0:02:23 > 0:02:26A volcano is an open mountain, and when it's active,

0:02:26 > 0:02:30it spits out hot molten rock called lava, and the whole island of

0:02:30 > 0:02:32Fernandina is an active volcano,

0:02:32 > 0:02:35so it is still growing and changing every day, isn't it, Kai?

0:02:35 > 0:02:37- Yes.- So do any people live on the island?

0:02:37 > 0:02:40There's no people. Just wildlife. It is a national park.

0:02:40 > 0:02:44- Everything is protected here. - So what are we going to see there?

0:02:44 > 0:02:47- Marine iguanas.- I cannot wait!

0:02:47 > 0:02:51A marine iguana is an iguana that can swim and they are only found in

0:02:51 > 0:02:55the Galapagos Islands. It is thought that a long time ago,

0:02:55 > 0:02:58a land iguana drifted out to sea from South America and landed here

0:02:58 > 0:03:00on the Galapagos,

0:03:00 > 0:03:03and because it was on an island, it needed to learn to do what?

0:03:03 > 0:03:05- It learned to swim.- That's right.

0:03:05 > 0:03:07They needed to go swimming to get their food.

0:03:07 > 0:03:09So, it looks like we're almost there, aren't we?

0:03:09 > 0:03:12- Yes.- I cannot wait to see it. Rory, while we drop anchor,

0:03:12 > 0:03:17will you please tell us some fun facts about marine iguanas?

0:03:17 > 0:03:19Of course, Ferne.

0:03:19 > 0:03:23One - marine iguanas can live to over 50 years old.

0:03:26 > 0:03:30Two - they can be mostly seen on the shore or on rocks close to

0:03:30 > 0:03:33the sea, and they can be found on many of the Galapagos Islands.

0:03:36 > 0:03:41Three - a large group of marine iguanas is known as a colony,

0:03:41 > 0:03:44and a group of females is known as a harem.

0:03:47 > 0:03:51Four - marine iguanas might be a little scary-looking but they are

0:03:51 > 0:03:54herbivores, which means they only eat plants.

0:03:59 > 0:04:04Five - marine iguanas are one of the few animals that can shrink in size.

0:04:04 > 0:04:06If they can't find anything to eat for a long time,

0:04:06 > 0:04:09they don't just get thinner, they get shorter, too.

0:04:09 > 0:04:10But once they find food again,

0:04:10 > 0:04:13they can regrow back to their original size.

0:04:13 > 0:04:15How amazing is that?

0:04:21 > 0:04:24My Pet And Me!

0:04:31 > 0:04:35We have arrived on Fernandina to see one of the most incredible animals

0:04:35 > 0:04:38that lives here - the marine iguana.

0:04:38 > 0:04:42And I can see why it's uninhabited because the island is literally just

0:04:42 > 0:04:44pure black volcanic rock.

0:04:44 > 0:04:48Yes. But it's hard to find marine iguanas because they're black

0:04:48 > 0:04:49- like the black rocks.- Yes.

0:04:49 > 0:04:53- Let's go find some. - I hope we can spot some.

0:04:53 > 0:04:56- Do you think we will?- Yes.

0:04:56 > 0:04:58Look, iguana poo.

0:04:58 > 0:05:03- Oh, wow.- Yes, it's green because iguanas eat green algae.

0:05:03 > 0:05:06It's REALLY green, isn't it? And it looks pretty fresh.

0:05:06 > 0:05:09- Yes.- Does that mean we're getting close?- Yes.- OK, come on.

0:05:35 > 0:05:37Wow, look how many there are.

0:05:37 > 0:05:40I know, there's so many, this is incredible!

0:05:40 > 0:05:44- Yes.- How many do you think there are?- 500 or more.

0:05:44 > 0:05:46I would not be surprised. There's too many to count.

0:05:46 > 0:05:50- Yes.- What is your favourite thing about them?- How they swim.

0:05:50 > 0:05:53- What do they swim like? - They move only their tail.

0:05:53 > 0:05:56So their arms by their side and they just use their tails?

0:05:56 > 0:05:58- Yes.- And that's why their tails are so long?

0:05:58 > 0:06:01- Yes.- But their arms are useful for something, aren't they?

0:06:01 > 0:06:04Yes, they have some nails, so when they get out of the water,

0:06:04 > 0:06:07sometimes there are waves, so they need to grab on the rocks.

0:06:07 > 0:06:11That is really important because the waves here are huge,

0:06:11 > 0:06:14so they use their nice, long claws to grip tightly

0:06:14 > 0:06:16to the rocks as they climb out.

0:06:18 > 0:06:23- Where do they feed?- They feed underwater and they eat plants.

0:06:25 > 0:06:27They hold their breath and dive.

0:06:30 > 0:06:34They can hold their breath for a big time, so they eat underwater.

0:06:38 > 0:06:42When a marine iguana is underwater, its heart rate slows,

0:06:42 > 0:06:45and this allows it to stay under the water for longer,

0:06:45 > 0:06:47but they can't really stay underwater for too long, can they?

0:06:47 > 0:06:50- Do you know why? - Because they get cold.

0:06:50 > 0:06:51That is exactly right.

0:06:51 > 0:06:55Marine iguanas are cold-blooded animals, which means that they get

0:06:55 > 0:06:58their body heat from the sun, so after they've been swimming,

0:06:58 > 0:07:02they come and bask or sunbathe on a rock to help heat up.

0:07:02 > 0:07:06They also gather together in groups and it's like a big iguana cuddle.

0:07:06 > 0:07:07They help to warm each other up.

0:07:07 > 0:07:11- So that's why they are all in a group.- Yes, exactly.

0:07:11 > 0:07:15- And their dark colour helps them absorb the sun too, doesn't it?- Yes.

0:07:16 > 0:07:19Because marine iguanas feed underwater,

0:07:19 > 0:07:22they end up swallowing a lot of saltwater, so they have

0:07:22 > 0:07:25a special gland right in between their eyes, and this helps to

0:07:25 > 0:07:28take the salt out of their blood and they end up sneezing it out

0:07:28 > 0:07:30and it keeps them nice and healthy.

0:07:30 > 0:07:34And what are these on their heads?

0:07:34 > 0:07:36I think it's like a Mohawk.

0:07:36 > 0:07:39It does, it looks like a pretty cool haircut, doesn't it?

0:07:39 > 0:07:42These nice, big crests on the top of their heads.

0:07:42 > 0:07:44I love them. I think they're fantastic.

0:07:44 > 0:07:47Me too. But they don't smell so good.

0:07:47 > 0:07:52No, they definitely do not smell very good, that is so right.

0:07:52 > 0:07:54- Shall we go see if we can spot some more?- Yes.

0:08:12 > 0:08:15Kai, this iguana here, do you think it's male or female?

0:08:15 > 0:08:17- He's male.- How do you know?

0:08:17 > 0:08:19Because he's bigger than the other ones.

0:08:19 > 0:08:23He is pretty big and he's got some amazing colours, too, doesn't he?

0:08:23 > 0:08:25- Yes.- Do you know why they're so colourful?

0:08:25 > 0:08:28To tell other females that he's the big iguana.

0:08:28 > 0:08:29That's exactly right.

0:08:29 > 0:08:33So they get these beautiful kind of greens and browns along them during

0:08:33 > 0:08:36breeding season, but they do this head bobbing, too.

0:08:36 > 0:08:40- Why do they do that?- That means that he's telling the other males that

0:08:40 > 0:08:42- this is his territory.- Exactly.

0:08:42 > 0:08:46They're just trying to scare all the other males off their patch of rock.

0:08:53 > 0:08:57There are so many marine iguanas here, aren't there, Kai?

0:08:57 > 0:09:01Yes. Fernandina is the place with the most amount of iguanas

0:09:01 > 0:09:02in the whole Galapagos.

0:09:02 > 0:09:04That is fantastic.

0:09:04 > 0:09:07But even though there are lots here, marine iguanas are endangered,

0:09:07 > 0:09:08- aren't they?- Yes.

0:09:08 > 0:09:12- Why is that?- Because they have predators like snakes and hawks.

0:09:12 > 0:09:17And there's also humans, cats and dogs.

0:09:17 > 0:09:21OK, so our pets are also causing their numbers to go down, too?

0:09:21 > 0:09:23- Yes.- That's very sad. But there's something else as well?

0:09:23 > 0:09:26Yes, the weather

0:09:26 > 0:09:32can make them die, because if it's really hot, their food disappears.

0:09:32 > 0:09:34So what can we do to help them?

0:09:34 > 0:09:38You can ask my dad. He has lived in the Galapagos a lot of time.

0:09:38 > 0:09:41OK, Robbie, what can we do to help these marine iguanas?

0:09:41 > 0:09:46Well, most important we have to protect the place where they live.

0:09:46 > 0:09:48We should keep an eye on the population always.

0:09:48 > 0:09:52OK, that's fantastic. Well, it's really important that we

0:09:52 > 0:09:55help to protect these amazing animals.

0:09:55 > 0:09:57And Robbie and the island guides do this

0:09:57 > 0:09:59by making sure that only a small

0:09:59 > 0:10:03number of people visit Fernandina, so the animals and the place

0:10:03 > 0:10:05that they live is undisturbed.

0:10:09 > 0:10:11My Pet And Me!

0:10:15 > 0:10:18Marine iguanas are such fascinating creatures, aren't they, Kai?

0:10:18 > 0:10:20Yes, I like them.

0:10:20 > 0:10:23Me too. If they could do absolutely anything, what would they do?

0:10:28 > 0:10:32If the marine iguanas could do anything,

0:10:32 > 0:10:34they'll have an ice-cream boat.

0:10:36 > 0:10:39They'll make delicious ice cream

0:10:39 > 0:10:45and sail around the islands in their boat, give some to all

0:10:45 > 0:10:46the other animals.

0:10:48 > 0:10:51Their favourite flavour of ice cream would be seaweed.

0:10:51 > 0:10:54Yum-yum.

0:11:08 > 0:11:11I have had an amazing time seeing the marine iguanas, but Kai has

0:11:11 > 0:11:15brought me to a very special spot, where we will be able to swim

0:11:15 > 0:11:17with them and see them in action underwater.

0:11:17 > 0:11:20I can't wait. Kai, what do you think we're going to see?

0:11:20 > 0:11:22Swimming, diving and maybe even we can see them feeding.

0:11:22 > 0:11:26I hope so. And there's lots over there, aren't there?

0:11:26 > 0:11:28Yeah, they're trying to get to the rocks where they can feed.

0:11:29 > 0:11:31There's a big one, look.

0:11:36 > 0:11:40Look, straight.

0:11:40 > 0:11:41Amazing.

0:11:41 > 0:11:44- Oh, look, there's loads. - There's a lot here.

0:11:49 > 0:11:51- Shall we take a closer look?- Yes.

0:13:18 > 0:13:22This is amazing. I can't get over how quickly they move under

0:13:22 > 0:13:24the water with their big tails.

0:13:24 > 0:13:27Yeah, they can hold their breaths for pretty much time.

0:13:27 > 0:13:29They can, they can hold their breath for ages as well.

0:13:29 > 0:13:32Marine iguanas can hold their breath for up to 45 minutes.

0:13:32 > 0:13:35That is at least 20 times longer than us.

0:13:35 > 0:13:38- Shall we go and have a look for more?- Yes.- Yes.

0:14:55 > 0:14:59There are two huge marine iguanas just eating on these rocks

0:14:59 > 0:15:02right below us, and they're just clinging on.

0:15:02 > 0:15:04There's quite a strong current here and they are just

0:15:04 > 0:15:06clinging on really tight and just chomping away

0:15:06 > 0:15:08at all of the seaweed and algae on the rocks.

0:16:16 > 0:16:18- Did you see it feeding? - Yes.- At the bottom.

0:16:18 > 0:16:21It's stuck there, just eating away.

0:16:24 > 0:16:25This is incredible.

0:16:35 > 0:16:39- That swim was amazing, wasn't it? - Yes.- What was your favourite part?

0:16:39 > 0:16:42When we saw the marine iguana feeding by the algaes.

0:16:42 > 0:16:45I know. I couldn't believe we saw that and I think the one we saw

0:16:45 > 0:16:48at the bottom feeding was the biggest one that I've seen so far.

0:16:48 > 0:16:52Yeah. And how they can eat while they're underwater.

0:16:52 > 0:16:54I know, and clinging on really, really tightly,

0:16:54 > 0:16:56because the current was strong, wasn't it?

0:16:56 > 0:16:59- Yeah.- Kai, I have had so much fun with you and you've taught me

0:16:59 > 0:17:03everything about these marine iguanas. Thank you so much.

0:17:03 > 0:17:04- Thank you too.- Put it there.

0:17:22 > 0:17:24My Pet And Me.

0:17:28 > 0:17:30- Hi, Rory.- Hi, Ferne. You look excited. How was your day?

0:17:30 > 0:17:33Oh, it was incredible. We went to an island and we saw

0:17:33 > 0:17:36these scaly sea creatures called marine iguanas

0:17:36 > 0:17:37and we even managed to swim with them.

0:17:37 > 0:17:39Wow, that sounds amazing.

0:17:39 > 0:17:43Oh, it was. And Kai taught me so much about how the marine iguanas

0:17:43 > 0:17:46live and what the local people are doing to help protect them.

0:17:46 > 0:17:49- It was fascinating. - We hope you enjoyed yourselves too.

0:17:49 > 0:17:55We just love sharing our animal adventures with you.
