Tired, jaded, under the weather? Let Dr Martin help you. I prescribe

:00:34.:00:44.
:00:44.:00:52.

a dose of war, neat, uncluttered We have got level-headed Joe, our

:00:52.:00:58.

producer. You can get in contact with her right now. We have got a

:00:58.:01:08.

fabulous audience. And we have got a friend or a Autumnwatch Unsprung,

:01:08.:01:18.
:01:18.:01:22.

Maya Plass. What on earth was that music, made? It was a disaster!

:01:22.:01:32.
:01:32.:01:37.

We have got to apologise. Why is it always made it has to apologise.

:01:37.:01:47.
:01:47.:01:47.

Last week, I made a mistake. Well, I didn't, who was it? We said that

:01:48.:01:53.

a wild boar could produce 100 piglets in her lifetime. But

:01:53.:01:58.

apparently that is complete rubbish. In fact, she can produce between 20

:01:58.:02:05.

and 36. Another thing we did do last week was to throw out to the

:02:05.:02:10.

audience an invitation to tell us what you think about the wild boar

:02:10.:02:20.
:02:20.:02:22.

controversy. We showed a film of They are an animal that would at

:02:22.:02:26.

some stage need management because they are at the top of the food

:02:27.:02:33.

chain. Martin, what you think? have lost the piece of paper it is

:02:33.:02:40.

written on. We had very emotional responses, as you would expect, and

:02:40.:02:48.

some responses from abroad. Berlin, wild boar have moved right

:02:48.:02:51.

into the heart of the city, and I have seen photographs of people

:02:51.:02:57.

waiting at a bus-stop with the animals routine over the Virgin

:02:57.:03:07.
:03:07.:03:10.

front of them. Are you serious? they live alongside them. Last week

:03:10.:03:15.

we had Caspar. He is the albino squirrel. Let's have another look

:03:16.:03:25.

at him. No, we don't have that. It is all going tremendously well,

:03:25.:03:35.
:03:35.:03:40.

isn't it? Oh, here he comes. Their ears. That has motivated you, the

:03:40.:03:44.

audience, to send in all sorts of albino animals. Have a look at

:03:44.:03:54.
:03:54.:04:03.

Oh, no, they are the badgers. This is from Martyn and Sue Wisbey. Here

:04:03.:04:07.

is a blackbird with a white head from Roger Brown. And perhaps most

:04:07.:04:16.

curious of all, and meadow brown, but it is white.

:04:17.:04:21.

One of the theories is that this is the result of a parasite that has

:04:21.:04:29.

got into the developing larvae of the butterfly. Where are becoming

:04:29.:04:37.

surrounded! They are ganging up on us. During the pupa stage, that is

:04:37.:04:42.

when the butterfly's colours are being put into the wings. They have

:04:43.:04:50.

little scales, and the blood is pumped through these, and it

:04:50.:04:55.

carries the pigment. After all of the raid is gone, it fills up those

:04:56.:05:01.

it is meant to, and they seal. Through the process, each of these

:05:01.:05:08.

things are filled. They dry out and fold into the scales we see on the

:05:08.:05:13.

butterfly. One idea for these aberrations is that while this is

:05:13.:05:18.

in progress during metamorphoses, a parasite has disrupted the

:05:18.:05:24.

distribution of pigment into these little sacks that become cells. It

:05:24.:05:32.

is still symmetrical, you say. it looked healthy. Yes, but it was

:05:32.:05:38.

sticking out like a sore thumb. The meadow brown is Brown for a reason.

:05:38.:05:45.

What about the White Badger's? think those weren't albino badgers.

:05:45.:05:52.

Albino badgers are actually very very rare. I think they are

:05:52.:05:57.

actually arithmetic. That is an animal with a reduced amount of

:05:57.:06:02.

melanin in its skin. You could see the strides if you look carefully.

:06:02.:06:10.

And we had a lot of pictures of white animals sent to us. You know

:06:10.:06:20.
:06:20.:06:20.

how we have... De you have more to say? No, I am waiting for you!

:06:20.:06:29.

always have a live animal and the studio - well, today, we have 50.

:06:29.:06:35.

We have a rock pool. Hannah is from the National Marine aquarium in

:06:35.:06:41.

Plymouth. This is fabulous. Have we really got 50 creatures in there?

:06:42.:06:49.

think it might be even more than that. This is a pretty unusual rock

:06:49.:06:54.

pool. This is something you wouldn't see in every rock pool.

:06:55.:07:01.

And this is all stuff we can see in this country? Absolutely. We will

:07:01.:07:07.

have a closer look at what is in here, and we are very much looking

:07:07.:07:13.

forward to it. You might have your own quiz, but we will have a quiz

:07:13.:07:22.

for you. We like this one. This week, are quizzes in the form of a

:07:22.:07:28.

map. We want you to identify which creatures use these pathways to

:07:28.:07:38.
:07:38.:07:43.

migrate. Creature any moves from the extreme north down to the UK.

:07:43.:07:48.

This one here moves around the seas of the UK, but then goes to the

:07:48.:07:54.

Atlantic Ocean. The last one goes in the reverse direction, starts

:07:54.:08:00.

around the Caribbean, goes across to West Africa and then comes up

:08:00.:08:07.

into the waters around the UK. And lastly this one, it originates

:08:07.:08:11.

around the UK and then his travelling down around the coast of

:08:11.:08:15.

Europe and West Africa and then diverting right across here to

:08:15.:08:25.
:08:25.:08:37.

South America off the coast of Send your answers in. This is quite

:08:37.:08:43.

a difficult one. I will be surprised if everyone gets this.

:08:43.:08:53.

The last one is tricky. Has anyone got it yet? Give us some questions,

:08:53.:09:00.

Michaela. This is a sweet question, handwritten on a piece of paper.

:09:00.:09:04.

This is Finley Whales, we're doing this first because he might have to

:09:04.:09:13.

go to bed soon. He sent us this: Why do some of my acorns look like

:09:13.:09:21.

this? My six-year-old asked me the same thing the other day when we

:09:21.:09:31.
:09:31.:09:32.

went for a walk. I would say that that is caused by a wasp. Thank

:09:32.:09:42.
:09:42.:09:44.

goodness for your son! This is where a wasp aid has been laid

:09:44.:09:48.

inside, and the egg and the La they modify the plant tissue to make it

:09:48.:09:54.

more a double and at the same time to make it grow so that it better

:09:54.:10:02.

protect them. These wasps are, and they lay their eggs into all sorts

:10:03.:10:08.

of plant material. Sometimes there can be so many of them that

:10:08.:10:13.

virtually every acorn on the tree has been turned into one of these.

:10:13.:10:19.

How many little Wasps would be in there? Normally just one, although

:10:19.:10:24.

in some instances, maybe more. It looks like to have grown either

:10:24.:10:34.
:10:34.:10:35.

side of the Acorn. -- two have grown. This was a fabulous question

:10:35.:10:44.

from a nine-year-old, so thank you Now, we have some people who will

:10:44.:10:50.

ask us questions on the video. We have got the group of the week from

:10:50.:11:00.
:11:00.:11:10.

the Cotswolds, who will personally Can you think of an ass question?

:11:10.:11:18.

We other keepers at the Cotswold Wildlife Park. My Name is Hanna.

:11:18.:11:25.

Where on a moth is the Johnston's organ found, and what is it for?

:11:25.:11:31.

am Chris, and my question is when does an invasive species have

:11:31.:11:37.

become classified as a native species. I was going to do my David

:11:37.:11:43.

Attenborough voice, but I don't think I will. With tawny owls,

:11:43.:11:53.
:11:53.:12:00.

which one says twit and which once I have those questions here. What

:12:00.:12:06.

is the Johnston's organ, and where is it on a moth? Isn't it on any?

:12:06.:12:16.
:12:16.:12:19.

On their lead? Oh, you will know, Chris. I think it is on the antenna.

:12:19.:12:29.
:12:29.:12:30.

It orientate them, like our inner ear. It is for balance. I think it

:12:30.:12:36.

is a balance organ. But there is something else on the leg. I think

:12:36.:12:43.

it is to do with sense of smell. You are thinking of the Jacobson

:12:43.:12:53.
:12:53.:12:54.

has organ in the roof of a snake. am! From Chris, when does an

:12:54.:13:01.

invasive species become a native one. This is so difficult. Everyone

:13:01.:13:08.

loves little owls. There is a perfect example, invasive species.

:13:08.:13:16.

Grey squirrels. There was a white one on the screen a moment ago.

:13:16.:13:20.

That is an adaptive evolutionary step, if they all became white we

:13:20.:13:27.

would love them! Horse chestnut is an invasive species, and we love

:13:27.:13:37.

them. You're avoiding answering the question. We normally sane native

:13:37.:13:41.

when the land bridge between the UK and Europe closed, because that was

:13:41.:13:47.

the last point at which mammals could crossover so most of the

:13:47.:13:53.

purists use that. But harvest mice, brown hares, in fact 48% of our

:13:53.:14:01.

terrestrial mammals, if you use that as the native., are not native.

:14:01.:14:07.

Where have you suddenly pulled that fact from? It is incredible. From

:14:08.:14:17.
:14:18.:14:24.

Debbie, tawny owls, which one does twit? And which one says whom?

:14:24.:14:29.

think it is the males and the females. Yes, it is a duet, and

:14:29.:14:38.

they do it so quickly, you think it is one of bird, but it is two.

:14:38.:14:48.
:14:48.:15:00.

That explains the coat! She was kept away as they are sorting out

:15:00.:15:08.

their territories. We are going to test you now, aren't we? Is Mia

:15:08.:15:13.

there? Here she comes. A couple of boring

:15:13.:15:18.

ied ems for you there. -- items for you there. These are

:15:18.:15:24.

my boring items. These two here. You are looking distracted already!

:15:24.:15:30.

These are the boring ones, you see. We are looking at the creatures

:15:30.:15:37.

which have made these holes. There is an animal which bores into

:15:37.:15:45.

wood. When I have seen pidit holes they are a nuisance. They bore into

:15:45.:15:49.

them. It will be something like that.

:15:49.:15:57.

Similar. You are close. It is a ship-worm. It is not a worm. It is

:15:57.:16:04.

actually a type of shell that goes in and uses its foot to attach

:16:04.:16:08.

itself and make all those holes. Presumably in the past that did

:16:08.:16:18.
:16:18.:16:18.

damage to wooden ships. That is why they used to put cooper plates

:16:18.:16:23.

under ships. They would do that to stop these things from eating all

:16:23.:16:30.

the wood. So.... Almost got you on that one.

:16:30.:16:40.
:16:40.:16:45.

This is another boring animal. not a dog well. That would be one

:16:45.:16:51.

hole. This is a boring sponge. You can dissolve it into a mineral acid,

:16:51.:17:00.

which will leave the little bits that are used to make the holes.

:17:00.:17:07.

You can find them left over in acid and put them under a microscope.

:17:07.:17:11.

You think of them as filtering animals. This is an especially

:17:11.:17:19.

interesting one. May I guess at this one? You can.

:17:19.:17:27.

This is an arris tottal's lat tern. It is the mouth part of an octopus.

:17:27.:17:35.

Sea our chin. -- urchin.

:17:35.:17:38.

That would have been inside. That is the right side. That is the

:17:39.:17:47.

mouth area and that is the bottom. So, this is, this dental apparatus

:17:47.:17:55.

sits inside. If you are lucky and go to an aquarium you may see them.

:17:55.:18:05.
:18:05.:18:05.

They scrape the algae off. It is an amazing piece of dental apparatus.

:18:05.:18:11.

I was sorry for our chins. That hole in the top there is its bottom.

:18:11.:18:21.
:18:21.:18:22.

I just want you to imagine what The last one here. When you hold it

:18:22.:18:31.

you are never supposed to make a mistake. Is that an old wife's

:18:31.:18:37.

tale? That is symmetrical. Do you know what it is, Martin?

:18:37.:18:44.

it a tooth. A grinding tooth of a ray. I think it's a grinding tooth

:18:44.:18:54.
:18:54.:18:55.

of a ray or a skaet. I would have said a -- skate.

:18:55.:19:04.

It is a grinding tooth of something. You are close. It is the throat

:19:04.:19:12.

teeth. It is something which the fishermen would have used as a good

:19:12.:19:16.

luck talisman. Sometimes they are silver-coated. So it is the teeth

:19:16.:19:21.

in the middle there. What do they use them for?

:19:21.:19:26.

It has been a pleasure. I have learnt things. That is what it's

:19:27.:19:32.

all about. How could you possibly know that answer? The answer to

:19:32.:19:36.

that? You need to come with me now. We need to go to our live animals

:19:36.:19:43.

in the rock pool. Sorry, audience. We are moving you around a bit.

:19:43.:19:48.

Show me something fascinating. is hard to pick anything out. This,

:19:48.:19:52.

you might well recognise as one of these, it is a mermaid's purse.

:19:52.:19:58.

Here you can see, if I shine the light. You can see something moving.

:19:59.:20:04.

That is fantastic. Inside, like a chicken egg, you have the yolk at

:20:04.:20:11.

the bottom. You can see this, they used to be dog fish, now they are

:20:11.:20:16.

cat sharks. You can see it wriggling around. I have seen lots

:20:16.:20:22.

like this. It is unusual to see them like this. What about this?

:20:22.:20:29.

That is a snake lock. You can see around the coast of Britain. These

:20:29.:20:34.

are great to see. One thing about rock pooling is you can use all

:20:34.:20:38.

your senses. When you touch it feels sticky. That is firing

:20:38.:20:47.

stinging cells at you. Trying to catch you and pulling you into its

:20:47.:20:53.

mouth. It uses its mouth as its bottom and releases sperm and eggs

:20:53.:20:57.

from there as well. Imagine if we did that!

:20:57.:21:02.

What a horrible thought! We have shrimps and prawns here and crabs.

:21:02.:21:06.

That is always a great one to get children to do, is find as many

:21:06.:21:14.

different species of crabs. We have her mit crabs in here. We have one

:21:14.:21:22.

isolated crab in there. Why is she in there? She is nasty. These are

:21:22.:21:27.

called the devil crab. They have bright red eyes. If I were to put

:21:27.:21:33.

my hand in there, she would put her claws up and try and get me.

:21:33.:21:40.

Where is the best place to take your kids to do this rockpooling?

:21:40.:21:47.

The beach, more than the woodland! Surprisingly. There r there any top

:21:47.:21:52.

spots? You want somewhere with a rocky sub strait to it and ask

:21:52.:21:59.

locally. Make sure you get a spring tide. When the moon is full or new

:21:59.:22:05.

you will see the most species. are not supposed to use a net.

:22:05.:22:09.

advise not to. If you are digging around with a net it is destructive.

:22:09.:22:15.

If you are digging around with your hands and a bucket to examine

:22:15.:22:19.

things and then put them back where you found them is better than using

:22:19.:22:25.

a net. It is good, to keep your kids interested to take an

:22:25.:22:29.

identification kit so they know what they are looking at.

:22:29.:22:35.

Get them to take a notebook to do drawings and identify them when

:22:35.:22:39.

they get home and look before you go out so you can help identify

:22:40.:22:45.

them together. It is an amazing thing to get ure kids to do. Our

:22:45.:22:50.

big kids will do it, as in Chris and Martin. They are going

:22:50.:22:56.

rockpooling next week. We are. If you are out and about

:22:56.:23:00.

rockpooling, send us your photos. We would love to see them. A live

:23:00.:23:06.

rock pool in the studio. What will we have next week, I wonder!

:23:06.:23:11.

There's a rockpooling guide on the web if you log on to it in fact. We

:23:11.:23:18.

must answer the quiz questions. Jo, did anyone get it right? A few

:23:18.:23:23.

people did. My favourite answer was from Luke. He thought A, it could

:23:23.:23:29.

be Santa Claus. Shall we ask the audience? What do

:23:29.:23:34.

you think A was? It is moving to the north of England and Scotland.

:23:34.:23:38.

Any answer? Geese.

:23:38.:23:45.

Barnacle geese. Ba creature to and from a

:23:45.:23:48.

mysterious place in the Atlantic here. It is in the water, quite

:23:48.:23:54.

clearly. Eels. That is correct.

:23:54.:23:59.

C, is a creature move from the Caribbean area and coming up into

:23:59.:24:09.
:24:09.:24:11.

the cooler waters of Europe. This was the tricky one. Anyone here?

:24:11.:24:18.

Turtles. Who said that? It's a leatherback turtle. The last one is

:24:18.:24:24.

a bird which is move from here, around the UK, it's going down the

:24:24.:24:28.

coast of Africa and to Argentina. It is the one and only?

:24:28.:24:33.

Storm petrol. Close.

:24:33.:24:39.

It's the Manx shearwater. Who got it right? Let's

:24:39.:24:47.

Good going. Round of applause for them.

:24:47.:24:54.

That was tricky, wasn't it? Are we doing marine questions next? We can

:24:54.:25:00.

give these to you. Question one, do you want to do that, tree sparrow.

:25:00.:25:07.

Have you any idea what this marine skull is? It looks like a beak of

:25:07.:25:12.

some sort and found on a beach in Northumberland earlier this year.

:25:12.:25:15.

You have a ruler there to show you the scale.

:25:15.:25:25.
:25:25.:25:26.

It is a bird. Looks like the ster number. The -- sternum.

:25:26.:25:31.

If If you flicked it up you would recognise it. It looks like that of

:25:31.:25:38.

a large bird, a goes or a gar net, something like that.

:25:38.:25:43.

The one got in touch via Facebook. "I didn't realise about the amount

:25:43.:25:48.

of jellyfish we have around the UK. How many are there? What is the

:25:48.:25:54.

most dangerous domestic one and any nasty visitors?" We had one nasty

:25:54.:26:01.

one, the Portuguese man-of-war. It is not a jellyfish. We have a

:26:01.:26:07.

picture of it. Bring it on. Look at that!

:26:07.:26:17.
:26:17.:26:18.

So, that is a one. One is the stinging bit and one is the

:26:18.:26:22.

digesting bit. It is confusing. It is strange. It

:26:22.:26:26.

is not quite a jellyfish. This sting is nasty. It is beautiful. I

:26:26.:26:36.
:26:36.:26:38.

had one in a tank one. The tentals go down and spring back up. A woman

:26:38.:26:46.

keeping a man-of-war. My daughter had it in a bucket swinging besides

:26:46.:26:51.

her. This is a massive jellyfish here.

:26:51.:26:57.

These are moon jellyfish. This is a smack of jellyfish.

:26:57.:27:03.

That's brilliant. If you get stung by them it feels

:27:03.:27:09.

like you are being smacked. They congregate. The males and females

:27:09.:27:15.

have to be together. Do we have more questions? Shall we

:27:15.:27:20.

find out what's going on this weekend? Jo, can you tell us....

:27:20.:27:27.

I'll go over to the map. Tell us what people can join in with.

:27:27.:27:32.

open weekend at near Scunthorpe. No need to book. People can turn up.

:27:32.:27:41.

On Sunday, you have to get up early. 8.30am, a guided migration walk at

:27:41.:27:51.
:27:51.:27:52.

Gibbs Point near -- at gibbral ta Point near stegness.

:27:53.:27:57.

It really is, as I said earlier, if you want to see the stall mon

:27:57.:28:03.

migration, a great time to see it and the bird migration. It will be

:28:03.:28:08.

a great Saturday for migrating birds. Get out and about.

:28:08.:28:16.

I have found this question. Positive. This is from T, wild boar

:28:16.:28:20.

and I would love to see them introduced in all protected forests.

:28:20.:28:24.

In a world we are losing so many wild animals we should embrace the

:28:24.:28:29.

ones we have. Roy, on the other side said wild boar need to be
