0:00:35 > 0:00:38..a land-loving animal terrorising people in the sea...
0:00:38 > 0:00:40Why are they in the water?
0:00:40 > 0:00:43..And the pearl fish that has a really bum deal on accommodation.
0:00:56 > 0:00:59Have you changed the place? It's a bit... Seems different.
0:00:59 > 0:01:02- Yeah, what do you think?- I like it. It's a bit eh...

0:01:08 > 0:01:11No, Tim, the correct term, I think you'll find, is actually minimalist.
0:01:11 > 0:01:13No, no, no! B-B-B-Rrraww! Bear! Rwarrr! Bear!
0:01:13 > 0:01:15THE BEAR ROARS

0:01:17 > 0:01:19ZAP! Is that better?
0:01:19 > 0:01:22Aw, yeah, that's way better. Lovely and warm.
0:01:22 > 0:01:24So, how are you doing this anyway?
0:01:24 > 0:01:26- Oh, I had a new button installed on the remote.- Oh.
0:01:26 > 0:01:28Shows us what it would be like if we lived in different places.
0:01:28 > 0:01:30- Did you leave the hairdryer on?- No.

0:01:32 > 0:01:36- Press the button! Press the button! Press the button!- OK, calm down!
0:01:36 > 0:01:39- ZAP! Is that better?- Awww - oooh, no.
0:01:39 > 0:01:42- Oh, it's chilly.- Oh, honestly, there's no pleasing some people.
0:01:42 > 0:01:45You know, some animals don't have a choice where they live.
0:01:45 > 0:01:47They have to set up home in very peculiar places.
0:01:47 > 0:01:50- Look, I'll show you. - C-C-Can we go home? Please?
0:01:50 > 0:01:53- ZAP! - Aw! Yeah, that's better.
0:01:53 > 0:01:54ZAP!
0:01:55 > 0:01:58On the southern tip of Africa, there's been an invasion.

0:02:01 > 0:02:04particularly menacing.
0:02:04 > 0:02:09They are very tough, very aggressive, quite dangerous animals.
0:02:09 > 0:02:12The stench? Oh, it stinks like hell.
0:02:12 > 0:02:14Ho-ho-ho. She's a bit angry.
0:02:14 > 0:02:16- That's Barbara. She lives there.- Oh.
0:02:16 > 0:02:21And when the wind blows we get all this black rubbish into the house.
0:02:21 > 0:02:24They can inflict extremely nasty scratches with their claws.
0:02:24 > 0:02:27And the noise at night is unreal.
0:02:27 > 0:02:28Awwrk! Awwrk!
0:02:28 > 0:02:31They bellow and bellow and bellow and bellow and bellow.
0:02:31 > 0:02:33Awwrk! Awwwrk! AWWWRK!

0:02:40 > 0:02:43I'll have you know that's one of my best animal impressions.
0:02:43 > 0:02:48- What? You... What? (Who's that?) - (Oh, that?)- (Yeah.)
0:02:48 > 0:02:52- (Professor Peter Barham. He's the expert in this story.)- Oh! Right!
0:02:52 > 0:02:56- Aw, would you do the, em... The, you know, the...- Yeah, OK.- Go on.
0:02:56 > 0:02:59Huah! Huah! Huah! HAUH!
0:02:59 > 0:03:01That is brilliant...
0:03:01 > 0:03:03What is it?
0:03:03 > 0:03:08- That's a lovely waistcoat. Oh - penguins!- African penguins.
0:03:08 > 0:03:10Ohhh, right.
0:03:10 > 0:03:12Naomi, would you explain, please?
0:03:14 > 0:03:18The culprits in question are, as Peter said, African, or
0:03:18 > 0:03:22jackass penguins, so-called because of their donkey-like bray.
0:03:22 > 0:03:23Hard not to love them.
0:03:23 > 0:03:27Unless of course you live in Betty's Bay. Isn't that right, Barbara?
0:03:27 > 0:03:29Look what they've done to the bush, here,
0:03:29 > 0:03:30they've killed all the garden!
0:03:30 > 0:03:34- Can you kill a garden? - Barbara seems to think so.
0:03:34 > 0:03:38- So, why are the penguins making homes in gardens, anyway?- Uh...
0:03:38 > 0:03:39- Let's ask the- Prof. Oh, yeah.
0:03:40 > 0:03:43Eh... OK... Thanks. Yeah.
0:03:44 > 0:03:46Well...
0:03:46 > 0:03:47ZAP!
0:03:47 > 0:03:51The real problem with Betty's Bay is that it's the only growing
0:03:51 > 0:03:55colony of African penguins, and there's no space.
0:03:55 > 0:03:58These animals arrived in Betty's Bay...1982, the first time.
0:03:58 > 0:04:01They've increased in numbers ever since and started to invade
0:04:01 > 0:04:04the areas where people live as well.
0:04:04 > 0:04:08- He's very good at this. - Did it all in one take, you know.
0:04:08 > 0:04:11'The penguins of course moved to where they could get more space.'
0:04:11 > 0:04:14As soon as the density goes up, they seem to want to move away.
0:04:14 > 0:04:18So, as the gardens move further away, they'll move to those gardens.
0:04:18 > 0:04:22- There's SO many of them.- Shhh! We're about to talk about breeding.- Sorry.
0:04:24 > 0:04:28Penguins breed the best in a really nice, dry burrow.
0:04:28 > 0:04:31Well, there are no dry, nice burrows, but a little shed is great.
0:04:31 > 0:04:34A building is great. Anything which has got a good roof on it - that's
0:04:34 > 0:04:36where they're going to nest.
0:04:36 > 0:04:40Finding the perfect habitat is key to their breeding success.
0:04:40 > 0:04:43And what these guys are looking for is enough room to breed and
0:04:43 > 0:04:46nest far away from the rest of the colony.
0:04:46 > 0:04:49It's THAT that's brought them into conflict with the locals.
0:04:52 > 0:04:54As the penguin colony grew in numbers,
0:04:54 > 0:04:57there were so many birds starting to breed in people's gardens...
0:04:57 > 0:05:02People found that they were too noisy, too smelly, um...
0:05:02 > 0:05:05The guano was killing off their plants.
0:05:05 > 0:05:10- Guano?- Ah, guano. Fancy name for sea bird poo.
0:05:10 > 0:05:11Ewww. Wish I hadn't asked.
0:05:11 > 0:05:13People just, for some reason,
0:05:13 > 0:05:16didn't like having penguins in their garden. It wasn't romantic.
0:05:16 > 0:05:20All things said, this population of penguins are thriving.
0:05:20 > 0:05:22And it's all thanks to people like Barbara.
0:05:22 > 0:05:25Well, their gardens, at least.
0:05:28 > 0:05:31- Thanks, Peter. Bye!- Bye!- Yeah, see you, mate. Thanks.- Bye!- Aw.
0:05:31 > 0:05:33What a nice man.
0:05:33 > 0:05:34WHIRRR!
0:05:34 > 0:05:37- Careful of the rope ladder!- Arrggh!
0:05:37 > 0:05:38CRASH! SPLASH! ROAR!
0:05:38 > 0:05:40THUMP!
0:05:40 > 0:05:42Owwww! I-I'm all right!
0:05:42 > 0:05:44- We have got to get that fixed.- Yeah.
0:05:48 > 0:05:50You know, penguins aren't the only critters to make their
0:05:50 > 0:05:53- home sweet home in unexpected places.- Oh.
0:05:53 > 0:05:57In fact, this encounter in the Caribbean caused quite a fright.

0:06:14 > 0:06:17SCARY MUSIC PLAYS
0:06:21 > 0:06:25All of a sudden, these things were beginning to swim towards the boat.
0:06:25 > 0:06:26- ON WALKIE-TALKIE:- Which way are they?
0:06:26 > 0:06:30And I don't know what they are. Why are they in the water?
0:06:30 > 0:06:31Oh, my God!
0:06:31 > 0:06:34Hey guys, help us out, we're swimming.
0:06:34 > 0:06:37I was trying to swim around them quickly and they were
0:06:37 > 0:06:40- faster than me.- Can you see them?
0:06:40 > 0:06:43They were shooting every direction, these legs.
0:06:43 > 0:06:45SCREAMS AND GASPS
0:06:45 > 0:06:48- But they were swimming fast.- Whoa!
0:06:48 > 0:06:54It was one of the most unusual things I've seen in my entire life.
0:06:54 > 0:06:56- ZAP! - Whoa - what was that?
0:06:56 > 0:06:59Well, Mike and his friends were on a shark spotting trip.
0:06:59 > 0:07:02- So, sharks, then?- What, with legs?
0:07:02 > 0:07:04Er... Uh, maybe not. So, what was it?
0:07:04 > 0:07:07- ZAP! - Oh, my God!
0:07:07 > 0:07:12Mike realised that, gliding through the waves towards him were...
0:07:12 > 0:07:13swimming pigs.
0:07:14 > 0:07:15SQUEAL!
0:07:15 > 0:07:17Ha-ha...no.
0:07:22 > 0:07:24The world's a crazy place.
0:07:24 > 0:07:27You took the words right out of my mouth, Mike.
0:07:27 > 0:07:31- I didn't know pigs could swim.- Again - what he said.
0:07:31 > 0:07:34- So, can they?- Here...
0:07:34 > 0:07:35- Play this.- OK.
0:07:37 > 0:07:40- What would you like?- Erm... Anything in the key of C.- OK.
0:07:40 > 0:07:43- Just get this thing going. You ready?- Yeah.
0:07:43 > 0:07:46HE PLAYS A COMPLEX TUNE Three, two, one...
0:07:46 > 0:07:49Paddling pigs have been known for some time.
0:07:49 > 0:07:50And they're actually pretty good at it,
0:07:50 > 0:07:54as this footage of the late, great Ralph The Swimming Pig shows.
0:07:54 > 0:07:57In his heyday in 1970s Texas,
0:07:57 > 0:08:03he would enthral up to 350,000 visitors at Aquarena Springs.
0:08:03 > 0:08:05And pigs were one of the few animals that don't have
0:08:05 > 0:08:07functional sweat glands.
0:08:07 > 0:08:11So to cool themselves down, they need to wallow in mud or water.
0:08:11 > 0:08:14So it makes sense for them to know how to swim.
0:08:15 > 0:08:16HE PLAYS A FINAL CHORD
0:08:16 > 0:08:20- Well, hang on, hang on - you said this was in the Caribbean.- Yup.
0:08:20 > 0:08:23The Caribbean famous for its deserted islands and distinct
0:08:23 > 0:08:25- lack of pigs.- Mh-hmm.
0:08:25 > 0:08:28- So how did these porcine paddlers, then, end up in paradise?- Ah...
0:08:28 > 0:08:30ZAP!
0:08:32 > 0:08:36The theories about how they got here have become local legends.
0:08:36 > 0:08:40One theory suggests they could have swum from another inhabited island.
0:08:40 > 0:08:42Or, that these Caribbean pigs are descendents of
0:08:42 > 0:08:44a few that were once shipwrecked.
0:08:45 > 0:08:49No-one knows exactly what happened, but stranded on a Caribbean
0:08:49 > 0:08:53island, they've learned a new way to get a free and nutritious meal.
0:08:53 > 0:08:57Rather than spend hours digging and searching for food,
0:08:57 > 0:09:01they've realised they can get hand-outs from passing boats.
0:09:01 > 0:09:04There was lettuce heads, French fries... Just food scraps.
0:09:04 > 0:09:07Mmm...
0:09:07 > 0:09:09- If I was a pig...- If?
0:09:09 > 0:09:12..I'd probably do the same, because this is a good combo.
0:09:12 > 0:09:15It really is! And, I tell you what - Mike would do the same.
0:09:15 > 0:09:18MUNCH MUNCH MUNCH
0:09:18 > 0:09:21If I was a pig, and I was stranded on a desert island, and I saw a
0:09:21 > 0:09:25boat, I don't know if I'd have the brains to just jump in the water,
0:09:25 > 0:09:29dodge the sharks, the stingrays...all of those things,
0:09:29 > 0:09:33to go out and see if I could get lunch.
0:09:33 > 0:09:36Or maybe not.
0:09:36 > 0:09:40And it just goes to show - animals really do turn up in the most
0:09:40 > 0:09:41unlikely places.
0:09:41 > 0:09:44- ZAP! - Give me that. Was that you?
0:09:44 > 0:09:46ZAP!
0:09:46 > 0:09:47I knew it!
0:09:47 > 0:09:51Just a spot of filming for Naomi's Nightmares Of Nature.
0:09:51 > 0:09:53How did...
0:09:53 > 0:09:55Shameless plug.
0:09:59 > 0:10:03Right, moving on. We've had swimming pigs, penguins in a garden...
0:10:03 > 0:10:05But when it comes to strange dwellings,
0:10:05 > 0:10:09this next creature trumps them both.
0:10:09 > 0:10:13The Great Barrier Reef. Thousands of species live here,
0:10:13 > 0:10:15and space is tight.
0:10:15 > 0:10:18It can make finding a home pretty tricky.
0:10:18 > 0:10:20Even out on the quieter reef-edge,
0:10:20 > 0:10:24the exposed sea-bed offers few hiding places.
0:10:24 > 0:10:26If you're neither strong nor well-armed,
0:10:26 > 0:10:28like this tiny pearl fish,
0:10:28 > 0:10:31you'll need to get creative when it comes to looking for shelter.
0:10:31 > 0:10:36Perhaps set your sights slightly stranger...
0:10:36 > 0:10:38Is that a sea cucumber?
0:10:38 > 0:10:41Yup. Not the most glamorous sea creature you'll ever meet,
0:10:41 > 0:10:45but it does have the solution to the pearl fishes' accommodation problem.
0:10:45 > 0:10:47- ZAP! - Slightly scared to ask.
0:10:47 > 0:10:50Slightly scared to tell you, so, I won't.
0:10:50 > 0:10:53I'll let marine biologist Helen Scales set the scene instead.
0:10:53 > 0:10:54ZAP!
0:10:54 > 0:10:56Pearl fish, they're little fish,
0:10:56 > 0:10:58they're quite vulnerable
0:10:58 > 0:11:02simply because coral reefs are full of hungry predators.
0:11:02 > 0:11:05You mostly would only see them out and about at night-time,
0:11:05 > 0:11:07where they go out hunting for plankton, the little creatures
0:11:07 > 0:11:10that live in the water column. And then during the day,
0:11:10 > 0:11:12they need to find somewhere to hide.
0:11:12 > 0:11:16OK, but where does the sea cucumber come in, then, Helen?
0:11:16 > 0:11:19So, sea cucumbers have, basically, a hole at the front end
0:11:19 > 0:11:20and the back end.
0:11:20 > 0:11:23The front end is where the food goes in,
0:11:23 > 0:11:25and all sorts of things happen at that back end.
0:11:25 > 0:11:29Um, it where they breathe, it's where they will excrete the sand
0:11:29 > 0:11:33that they've been eating, any other digestive material will come out.
0:11:33 > 0:11:37So, it's a kind of, one-hole-does-many-things.
0:11:37 > 0:11:41And therein lies the clue, because the pearl fish makes its cosy
0:11:41 > 0:11:44home inside the sea cucumber's bottom.
0:11:44 > 0:11:46POP!
0:11:46 > 0:11:51Oooh! Oooh, no! No! Aww, no!
0:11:51 > 0:11:53It has to be one of nature's weirdest living arrangements.
0:11:53 > 0:11:55WHOOSH - POP!
0:11:55 > 0:11:58- Ohhh! Are you having a laugh? - No - for real.
0:11:58 > 0:12:00And there's no better place?
0:12:00 > 0:12:02- Nope.- Seems like a BUM deal to me.
0:12:02 > 0:12:07- Oh!- Uh-oh!- Ew!- Ew!- Ewww!
0:12:07 > 0:12:12MUSIC: I Can't Tell the Bottom From The Top by Kevin Rowland
0:12:14 > 0:12:18Well, if you can imagine those sandy areas next to a coral reef,
0:12:18 > 0:12:20there's really nowhere to hide. There's just flat sand.
0:12:20 > 0:12:24There aren't many rocks or any other holes or crevices to hide in.
0:12:24 > 0:12:26But there are sea cucumbers.
0:12:26 > 0:12:29However, whilst the pearl fish may have set its sights on
0:12:29 > 0:12:33a potential home, entry isn't always guaranteed.
0:12:33 > 0:12:37If a sea cucumber does have an idea that maybe there's
0:12:37 > 0:12:40a pearl fish around, it might close up its bottom,
0:12:40 > 0:12:43and so for a little while it won't be...open for guests.
0:12:45 > 0:12:49- Dare I ask, how does it gain entry to its bottom-y abode?- Well...
0:12:49 > 0:12:51ZAP!
0:12:51 > 0:12:55By sticking the tip of its tail into the sea cucumber's rear end,
0:12:55 > 0:12:59the pearl fish cuts off its oxygen supply, knowing that the
0:12:59 > 0:13:03sea cucumber will have to open up to breathe eventually.
0:13:03 > 0:13:05And when it does, it's home sweet home.
0:13:07 > 0:13:11Pearl fish really are the worst tenants.
0:13:11 > 0:13:14Well, there's just no accounting for some behaviour.
0:13:16 > 0:13:17PARP!
0:13:17 > 0:13:20Oh!
