That's very nice, you guys, but it's nothing like a coral reef.
According to Ms Frizzle, a reef is a shallow place in the ocean...
Ms Frizzle also said that a coral reef is built by tiny animals.
With tiny tools?
CAR-LOSŁĄ
l meant tiny, underwater animals, CarlosŁĄ
Well, according to my research, coral reefs are aliveŁĄ
And gazillions of fish live there.
So can we move the rest of the fish in there from the other tank to the coral reef now?
WaitŁĄ
We need one more thing to go right......
thereŁĄ lt's the only space left.
And it's perfect for the shell Wanda and l are going to paint...
ArrrŁĄ AvastŁĄ Me heartiesŁĄ
Look at what l just made for the new aquariumŁĄ
What about our shells?
Your shell, DA.
l decided to make this treasure chest for our coral reef.
And l see the perfect spot for it.
But WandaŁĄ You were supposed to make something together.
Miss Frizzle said that everything we put into the reef had to be done by partners.
Sooo, l thought of it and l made it. What better partnership is there.
What's that?
MS FRlZZLEŁĄŁĄ
Good morning, classŁĄ
My my, look at all these wonderful things in the aquarium.
UhŁĄ And a treasure chestŁĄ
Do you like it? l made it myselfŁĄ
Even though we were supposed to make something togetherŁĄ
But you know l work better alone.
Hmm, your treasure chest reminds me of something. Don't go awayŁĄ
AhŁĄ Here it isŁĄ
My great-great-great-great-great-great
Grandfather Red beard's treasure mapŁĄ
Red Beard?ŁĄ?
He was the pirate in the family - a long, long time ago, of course.
You had a real pirate in your family??
Why not? This map's been in the family for centuries.
WowŁĄ A real map of a real place.
Then this must be a real coral reef.
And the treasure...must be real, tooŁĄ ls it, Ms Frizzle?
Well, Wanda, there's only one way to find out.
TO THE BUSŁĄŁĄŁĄ
As my great grandma told me, Red Beard was no ordinary pirate.
Why am l not surprised?
lnstead of making his victims walk the plank,
he took them along on adventures in his pirate ship.
You mean he took people on field trips, too?
Oh, yesŁĄ They went everywhere and anywhereŁĄ
No wayŁĄ
He must've robbed and plundered like a normal pirate because he left a treasureŁĄ
We don't know that for sure, Wanda - all we've got is a map.
And according to that map...
We're hereŁĄ
Coral reef hoŁĄ
Drop anchorŁĄ
Coral reef? Where?
Good question, RalphieŁĄ And l'm going to answer itŁĄ
Partners, everyoneŁĄ Two by two, please.
Partners??
Yes, you know like ...
Keesha and Ralphie...
Tim and Carlos...
Phoebe and Arnold...
...and you and meŁĄ
But l don't need a partnerŁĄ l'm a pirate, not a weasly wimpŁĄ
But as old Red Beard probably used to say...
Go into the sea without a partner, matey, and you can get into deep troubleŁĄ Yeow.
Ready, partner?
Yeah...but l still don't know why.
You'll need the map, Wanda - and don't worry, it's waterproof...
Thanks, Ms FrizzleŁĄ To the treasureŁĄ
Wa-ha-hooooooŁĄŁĄŁĄŁĄŁĄ
ls this it?
ls this where the treasure is? lt doesn't look anything like our aquarium.
Yeah, where are all the fish?
According to my research...
there's not much food and no shelter for fish in deep ocean water.
But there are lots of different kinds of fish living in a coral reef.
So where's the reef?
All l see is a lot of deep water.
According to this treasure map...
WhoaŁĄ Hold everythingŁĄ Look at that
Look at the size of those fishŁĄ
Now we're talkin' coral reefŁĄ
And now we're talkin' fishŁĄ
But are we talkin' treasure?
WandaŁĄ Wait for meŁĄ
Hurry up, DAŁĄ
PartnersŁĄ They slow you downŁĄ
WandaŁĄŁĄŁĄ Wait for meŁĄ
What's that?
lt looks like an old chain....
... and it's got a pirate's mark on itŁĄ
LookieŁĄ lookieŁĄ Look, that chain is the dotted line on the mapŁĄ
See? lt leads to the treasureŁĄ
l think it goes... somewhere over thereŁĄ
Not so fast, Wanda.
We've got to stick together. We're partners, remember?
What good did a partner ever do anyone, anyway?
Good question, WandaŁĄ
Liz?
Oh noŁĄ WaitŁĄ l take back the questionŁĄ
Oh noŁĄ Me and my big mouthŁĄ
How am l going to find the treasure now??
l guess we'll just have to wait and see, Wanda.
l've never been a sea anemone before.
Sea anemoneŁĄ? ls that what we are?
According to my research,
a sea anemone is a marine animal which looks like a plant.
Yeah - looks like a plant... ... and acts like a plant.
Yeah, we can't exactly move from one place to another.
But you get a good view of the fish from here...
OoopsŁĄ Not enough food for twoŁĄ
Okay, so you're sea anemones, but what are the rest of us, Ms Frizzle?
You're hermit crabs, ArnoldŁĄ
Hermit crabs? Sure, why not. Seems safe enough - nice, hard shell...
Hey, lookŁĄ A rockŁĄ
YlKESŁĄ That rock was a fishŁĄ
And it ate that other fishŁĄ
What kind of place is this?
A crowded one, Arn.
The kind of place where you either eat or get eatenŁĄ
A place where it's every critter for herselfŁĄ
But, how am l going to get to the treasure when l can barely move?ŁĄ
Well, since l'm a crab - and crabs can walk, l'll just follow the chain.
Aren't you glad you have a partner now...Wanda?
WhoaaaaŁĄŁĄŁĄ
What's going on?
Don't look now, but l think it's chow time...ŁĄ
l knew l should've stayed home todayŁĄ
OctopusŁĄŁĄŁĄŁĄ
OHH NOOOOOOOŁĄ
Over here, ArnoldŁĄ
Nobody seems to want to swim near us sea anemones.
That's because...
... we stingŁĄ
Lucky you, PhoebŁĄ
That means they leave you alone, and won't eat youŁĄ
So if we stay close enough to you, they won't eat us eitherŁĄ
Hey, DAŁĄ
This is bad enough as it is wthout you pushing me around.
Hey guysŁĄ
Look what that real hermit crab's doingŁĄ
Why would a crab want an anemone on its head?
For protection, that's whyŁĄ The anemone stung the octopusŁĄ
Come on, let's see if it'll work for usŁĄ
You know what, buddy? lt's kind of nice being able to move.
...and l get to eat what you eat.
And you give me protection. Now that's what l call a partnershipŁĄ
l just thought of something, DA - if l get up on your shell......
l'LL protect YOU from the octopus - and YOU can take ME to the treasureŁĄ
You got it, partnerŁĄ To the treasureŁĄ
Come on...partner. FasterŁĄ
HeyŁĄ lt workedŁĄ You're stinger scared it away.
Nice one, WandaŁĄ Way to goŁĄ You scared away the octopusŁĄ
Yeah okay, so that's the good news...
How are we going to follow the chain through that teeny-tiny space?
Now there's a question worth diving into, WandaŁĄ Oh, Li-izzzzŁĄŁĄ
Well...at least l can move nowŁĄ What are we, Ms Frizzle?
We're pistol shrimp, WandaŁĄ
We live in burrows in the coral rubble. Can you dig it?
You betŁĄ Now l can dig a hole through here so we can get to the treasureŁĄ
What about us, Ms Frizzle? We're fish - and fish can't dig.
You're right, Tim. You're a goby fish.
A goby fish?
Didn't l see a fish that looked like us get eaten? Time to find a place to hideŁĄ
But where?
These claws are great for digging - better than a shovel any day.
But l sure can't see very well.
Even if l do find the treasure...l probably won't see itŁĄ
S-s-s-sharkŁĄ HideŁĄŁĄ
Hide? Where? There's no roomŁĄ
Do you see what l see?
Hiding placesŁĄ
Move over WandaŁĄŁĄ
DAŁĄ What are you doing?ŁĄ??
Hide... there's a...
You're wrecking my tunnelŁĄ
There won't BE a tunnel if you get eaten by that sharkŁĄ
Shark?? Shark?ŁĄ
SharkŁĄŁĄ
Whoa, thanks for warning me, partner. l couldn't see that shark coming.
Man, it's a good thing for us gobies that you shrimp dig places to hide
and don't mind sharingŁĄ
And it's a good thing for us shrimp that you gobies warn us
when there's danger we can't see.
ls it just me or are shrimp and gobies partners for a reason?
SuRVival, Ralphie, suRVivalŁĄ Each one helps the other to live.
Hey, you guysŁĄ LookŁĄ
You won't believe itŁĄ
What is it? What is it? l can't see.
Wowwww! Awesome!
ls it the treasure, DA?
NO...But l see where the chain goes. l'll check it out.
Don't go without meŁĄ l'm your partner, remember?
OoohŁĄ l need a partner who can get me safely to the treasure, Ms Frizzle.
Oh, Li-assŁĄŁĄ
What this time??
YesŁĄ This is more like itŁĄ
What's more like it? l know l'm a shark...
...but what are you?
We're remoras, DAŁĄ Fish with suction cups that attach themselves to sharksŁĄ
So they can get a free ride - right, Ms Frizzle?
A free ride and a free mealŁĄ Wha-hooŁĄ
But what do we sharks get out of this deal? OohŁĄ Something's itching meŁĄ
Maybe we get rid of these little critters stuck all over your skin.
Mmm - tastyŁĄ
Thanks, Ralphie. What a partnerŁĄ Those guys were really starting to bug meŁĄ
KEE-SHAŁĄ
l guess these little crunchy guys are tasty for me - and bad for you ...
but what l really think is that this twosome is ready to find the treasureŁĄ
What do you say, partner?
l say, not if we find it firstŁĄ Go, TimŁĄ
Oh yeah? Hang on, WandaŁĄ
Hey, what's wrong with the reef over here? lt looks almost...dead.
Never mind that - the treasure's in thereŁĄ Let's get itŁĄ
l uh...l don't like the look of this place, WandaŁĄ
DAŁĄ lt's the treasureŁĄ
Let me help, l'm bigger and strongerŁĄ
Now we're talking partnershipŁĄ
Oh nooooooŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄ
WandaŁĄ DAŁĄ Are you all right?
WE found itŁĄ We found the treasureŁĄ
But when we pulled it out - look what happenedŁĄ
A big piece of the reef broke offŁĄ
And the treasure's underneath all this stuffŁĄ
lf you ask me, this whole part of the reef looks pretty sickŁĄ
lt's lost its colour, too. Could something be wrong with it?
l think that's a question we can build on, Dorothy Ann. Don't you, Liz?
What do you know - we're humans againŁĄ
All the better to use your megamagnifiers, my dearsŁĄ
Now l know why they say the reef is alive - lookŁĄ
lt's made of little animalsŁĄ
Boingo, CarlosŁĄ Little animals called polyps.
The coral reef is a limestone skeleton built by these polyps.
And they're building new coralŁĄ
Hold onŁĄ
l think these polyps over here have something the ones in the sick part don't haveŁĄ
You're right, Tim.
Each polyp has something inside it.
And that stuff is...Algae
Algae?
You mean like the scum l got on my shoe when l stepped in the pond?
Wait a minute... wait a minute.
This whole day has been about partners working together, right?
Right.
First we were hermit crabs and sea anemones...
The sea anemones protected the crabs...
And the crabs moved the sea anemones around.
They're partnersŁĄ
And then we were pistol shrimp and goby fish...
The shrimp dug hiding places that helped protect the gobies...
While the goby fish kept an eye out for trouble for both of them.
PARTNERSŁĄ
And don't forget the sharks and remorasŁĄ
PARTNERSŁĄ
Where critters meet to eat, it's sometimes better to cooperate than to competeŁĄ
So do coral polyps get something from the algae? Are they partners, too?
Righteously reasoned, WandaŁĄŁĄ
Since algae is a plant, it makes its own food from sunlight.
lt gives off wastes which help the polyps make the reef.
CoolŁĄŁĄ
So if the algae helps the polyps build reefs - what do the algae get out of it?
lf you ask me, the algae get a nice safe place to live, away from these hungry fish.
OhŁĄ Fantastically figured, PhoebeŁĄ
A partnership which is good for both partners is a partnership that lastsŁĄ
So how come these polyps on the sick part of the reef...
don't have any algae partners?
Maybe they're just being silly like l was. Hey, polypsŁĄ
Take it from me -
sometimes it's better to work with a partnerŁĄ Really - trust me on this oneŁĄ
l don't think they can hear you, Wanda.
According to my research,
if the water where coral lives get polluted, the polyps get rid of their algae partners.
But why would water be polluted over here...and not the water over there?
The only thing about this place that's different is -
this is where l found...
...the treasureŁĄŁĄŁĄ
This chest is made of some kind of metal.
Hmm. Looks like copper to me.
Red Beard knew many things, but he didn't know about pollution.
You mean Red Beard's treasure chest could be polluting the reef, Ms Frizzle?
lt could indeed, KeeshaŁĄ
Well, then, let's remove the source of the pollutionŁĄ
Hit it, LizŁĄ
Now let's clean up this placeŁĄ
WandaŁĄ What are you doing?
Trying to get some clean water in here to give these polyps a chanceŁĄ
Good ideaŁĄ
WHOAŁĄŁĄ
Way to go, BusŁĄŁĄ
lt's workingŁĄ
These polyps just took in some algaeŁĄ
And they're starting to build coral againŁĄ
The partnership is workingŁĄŁĄ
But won't it take forever for these polyps to build up the reef again?
Never say forever, DAŁĄ Normally it would take hundreds of years,
but l think today we'll speed up the process a little.
Take it away, LizŁĄ
YayŁĄŁĄŁĄŁĄ The polyps and algae did itŁĄŁĄ They've built the reefŁĄ
Careful...
easy does it...
So, who's going to open it?
What is it??
lt's a model of his shipŁĄ CoolŁĄ
There he is - Great-great-great-great-great- great-great-great-great-
Grandfather Red BeardŁĄ
Ah, little did he know his treasure chest would one day hurt the reef.
lf he were here, he'd thank you for finding it and pulling it out. Right, Red Beard?
What do you think this is?
lt looks like some kind of handle.
Why don't you pull it?
Well, what do you know? lt's an M. S. G.
A whatŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄŁĄ
A magic Spanish Galleon.
l told you Red Beard was no ordinary pirate...
Magic School Bus, the producer speaking.
Hi. l just watched your show on coral reefs and thought it was terrific.
But l have a couple of questions on this partnership thing.
Fire away, buddyŁĄ
ls it true that most animals have partners like the ones you showed?
Well, partnerships are a little unusual. That's why they are so interesting.
Most of the time...
...animals compete with each other, for things like space...mates...
and most often, food.
Partnerships happen when each animal partner benefits the other -
and each does better as a result.
And coral reefs are a good place to see that happeningŁĄ
But some animals just benefit from other animals without giving back, right?
AbsolutelyŁĄ Take the coral reef crab, for example.
lt lives under the spines of the black sea urchin.
The urchin doesn't get anything out of it -
but the crab gets some well-needed protection.
CoolŁĄ
Okay, now tell me the truth. ls a coral reef really alive?
You bet it is, palŁĄ
The hard coral is part of the shell-like home of the polyps...
and millions of polyps live together, building the reef, year after year.
Do reefs really get sick like you showed?
Unfortunately, they do - for lots of different reasons...
...including pollution and other human activities that harm reefs
and the animals that live in them.
Speaking of animals, aren't the ones that cooperate just being nice to each other?
Sorry, animals aren't nice, except maybe to their babies.
ln fact, they tend to eat each other a lot.
Thanks for calling - and thanks for your interest in coral reefs.
Hey, coral reefs are one of the world's great treasures.
We need to do what we can to protect 'em.
You got that right, partnerŁĄ
Aren't you going to share your lunch...partner?
Never mind.
