THE COCONUT CRAB (AYUYU)

The coconut palm (Cocos nucifera) is the best known of the drift fruits, those seeds that

travel the oceans colonizing new lands. The coconut, though, has not traveled alone. It has

served as a raft carrying a hermit crab. An unlikely pair of voyagers: an baby plant inside

the husk and a tiny crab clinging to the outside.

The coconut crab (Birgus latro) begins its life as a larva in the ocean. It is no more than

another tiny life form in the world of plankton. After several sheddings of skin, it leaves the

sea to become a land crab. A few coconut crabs have made it to other islands while still

larvae. But to colonize isolated islands, the crabs probably have arrived by rafting.

Coconut crabs are the largest of the hermit crabs. They can grow to 75 centimeters (almost

30 inches), weigh up to 4 kilograms (8.8 pounds), and live 50 years. Unlike most hermit

crabs that need to occupy a shell, the coconut crab forms a hard shell to protect its

stomach.


The coconut crab is capable of climbing the trunk of the coconut palm to get to its

main food. The crab selects a coconut and using its pinchers, cuts the coconut free.

The crab descends from the palm and pries the husk from the coconut. After the

husk is removed, the crab pounds the coconut against a rock until it breaks open. It

may take the determined crab two days to open the coconut; often it must stop to

defend its prize from other crabs.

The coconut crab has adapted to natural environmental pressures. On small islands

where there are no people, the crab is diurnal, active during the daylight hours. But

where humans are present, the crab is nocturnal (active at night). On some islands,

the crab has altered its diet from coconuts to lau hala (Pandanus tectorius), another

fruit whose seeds drift on the ocean currents. Coconut crabs with a main diet of

coconuts are blue and lavender. Crabs with a diet of mostly Pandanus are bright

orange.

But humans have put too much pressure on the crab population. Coconut crabs are

now rare creatures and on some islands have been extirpated (locally extinct). Their

habitats have been destroyed and they have been over-collected. Coconut crab meat

is considered a delicacy and brings a high profit. Hunters often ignore the laws meant

to protect this remarkable creature.


NONPOINT SOURCE POLLUTION

In The Commonwealth of the Northern Mariana

Islands it rains very much.

When the rain hits the ground, the water picks up

many things such as chemicals, pesticides, oil, dirt,

and waste created from humans and animals.

The water then moves these things downhill.

These things end up in the lakes, lagoons, and

ocean as pollution.

This pollution is called nonpoint source pollution

because it does not get traced back to a particular

point, such as a drain or a pipe.

This pollution is filled with chemicals that can kill

the coral reefs, fish, crabs, seagrass, sea turtles,

and other marine animals.


Because we depend on food

from the sea, tourism from

people enjoying the sea, and

the beauty of the sea, we

need to protect the sea

animals from these

pollutants.

If we do not be careful, we

will be sorry in the future

because we will not have

clean food, beautiful coral

reefs, and the animals that

live off of the food the coral

reef gives us.

If we can stop the water from

reaching the ocean,

temporarily, and do things

around the house to stop

these pollutants from getting

picked up by the rain, we can

help the sea animals and

ourselves.


Things we can do to help at home are:

1. Do not overuse chemicals, cleaners, and

detergents.

2. Wash your car on the grass, it works as

a filter to clean the water before it

enters the stream.

3. Keep chemicals, batteries, oil, and other

toxins out of the rain.

4. Clean up after your pets.

5. Put trash in trash cans, not on the

ground.

6. Create an erosion plan for your property

so dirt does not leave the property.

7. Make sure pig waste does not leave the

area.

8. Check your septic tank for leaks.

9. Dispose of toxic chemicals properly.

10. Good housekeeping is clean

housekeeping.


LAST NIGHT IT

RAINED VERY

HARD, CARRYING

WATER TO THE

OCEAN


ZZZZ

ZZZZZ

ZZZ

ZZZZ

Z!


I feel a little sick

as well, I wonder

what’s

happening?

Hi Clarence, How are you?

Hold On,

I am

dressing!

I’m O.K., Dina

The Dolphin, but

I think I am

getting a little

sick!


O.K., Where

do you want

to go to lunch? They are

in Rota, can you

give me a piggy

back ride?

Let’s go to lunch

with Gilbert the

Gecko and Tommy

the Sea Turtle to

see how they feel.


Dina the Dolphin and Clarence

the Coconut Crab swam from

Saipan to Rota. They both were

complaining about being sick,

yet they did not know why they

felt so badly. Tommy the Sea

Turtle was a very smart animal,

so they thought they would go

visit Tommy in Rota, for lunch.

Gilbert the Gecko was going to

be in Rota also…..


Tommy, Clarence, Dina, and Gilbert were enjoying

lunch when Freddy the Frog jumped out to meet

everyone. They invited him to enjoy some lunch and

discuss why they were feeling sick.


Well, the reason why you are all feeling sick is because

Saipan, Tinian, and Rota have stuff called

NONPOINT SOURCE POLLUTION (NPS pollution). NPS pollution is

caused by rainfall moving over and through the ground, which turns turns

into

soup. As the soup moves, it picks up and carries away natural and and

human

made POLLUTANTS.

The water takes the pollutants to lakes, puddles, the lagoons,

and the AQUIFER where our drinking water comes from.


OH MY GOSH!!!!

I understand what you are saying Tommy

the Turtle, but what is the difference

between Natural Pollution and Human

Made Pollution? And, What is an Aquifer?


Well Clarence the Coconut Crab, this is very

important, so make sure you really listen to me

here….

NATURAL POLLUTION is stuff like your pet’s

droppings, chicken droppings, pig droppings, as

well as droppings from rats, shrews, and other

animals on the islands. Natural pollution can also

be dirt that is carried by the water from a

construction site. This is not the humans fault, but

they can help control it.

HUMAN MADE POLLUTION is stuff that the

humans make and do not throw away properly.

This can

be trash, oil, gasoline, used car batteries, cleaning

chemicals, toxic waste, paint supplies, and more.


Good answer Gilbert the Gecko,

I am glad to see you have been

doing your homework!

An Aquifer is kind of cool.We are lucky to

have one, but we need to protect it.

An AQUIFER is like an underground rock sponge

that the water goes into after it rains.

These rock sponges fill up with water so that we

can drink water after we dig a well into it.

We need to keep the water very clean or

everyone will get sick.


THAT

is

COOL!!

I will

Help you

guys!!! Me Too!

Well,

We need to tell everyone

about this !!!

We need a plan,

Do you have any

Ideas Freddy the

Frog?


Ribbiiiit!

I think we can tell all the kids from

Rota, Tinian, and Saipan that they need

to Protect their ENVIRONMENT. They

need to understand that everything they

do can cause NPS Pollution, so they

have to be careful.

Everyone needs to help so that the fish

we eat and the water we drink are clean.

Every Kid needs to properly dispose of

their waste and tell a friend to do the

same. BUURRP!

Excuse me!! Good Lunch!


That was gross Freddy the Frog!!

I like your plan though.

We need to have the kids tell their

parents about NPS Pollution also.

Parents are causing pollution without

even knowing it sometimes.

This Nonpoint Source Pollution is very

MYSTERIOUS .

You have to be very smart to understand it.


See you guys,

Good Luck

Sure thing

Clarence, Hop

on Baby, Lets GO!!

Hey Dina the Dolphin, Can you take me to Tinian

so we can ask the Pigs if they know any

more about this mysterious NPS Pollution?


Dina the Dolphin and

Clarence the Coconut Crab

were full, said goodbye to

their friends, and headed to

Tinian. They swam all the

way in a few hours in order to

see the pigs before they went

to sleep...


What about us Chickens and Roosters?

NEVER MIND Mr. Rooster!!

Welcome Dina and Clarence,

What can we do for you today?

Good Afternoon

Pigs!!!

Good Afternoon

Chickens,

Roosters, and Pigs

Sorry, We are a little

tired from

Our Journey from Rota.


Sorry we have not seen you

for a while, but, we really

need your help.

I think we can

help you!!

Yahh, We are

seeing if you

know how to

help prevent

NPS Pollution.


Well, as you can see, when it rains, there is water

RUNOFF. This carries BACTERIA from our

droppings into the aquifer, streams, lagoons, and the

ocean. Our owners have to build a natural filtering

system so the water gets clean again before it leaves

our area. By doing this, we will not hurt anyone,

and you two guys will feel better.


PIG WASTE

IN THE

WATER

NATURAL FILTER

CLEAN WATER

WOW! The

plants clean the

water!!!

You can see the

FILTER here where

the grass is. It

makes the water

even cleaner if we

add more plants and

bushes to the

RUNOFF.


PIG WASTE

IN THE

WATER

NATURAL FILTER

CLEAN WATER

Does that

work

for the

chickens

also?

Your owners

are so smart!

Yes, it is CLEAN

WATER!!!!!!!!!!

We also have a

plastic film under

our pig pen so the

dirty water does not

go into the

AQUIFER.


Oh yes, This works for the chickens waste also.

I hope the kids of Saipan, Tinian, and Rota can

make sure that their parents are protecting the water

like we are .

You guys should go to Saipan and see how to help

around the house to protect the ENVIRONMENT.


Yah , Yah, beat it guys!

BYE!

COME

BACK

SOON!!

Let’s do it

Dina!!

Quiet

Rooster!!

Good Luck

on

your

journey,

good to

see you.

O.K.

Clarence…

Thanks for

the help

Chickens,

Roosters,

and pigs.


Clarence hopped on Dina again

and they were so happy that the pigs

were being safe.

Clarence and Dina spent the

night out at sea and went to Saipan in

the morning to see how kids can help

the NPS POLLUTION problem at

home. Hopefully, Joaquin Salas was at

the beach, so they could talk.


HI Clarence the Coconut Crab

and Dina the Dolphin, Long

time no see.

Hi

Joaquin,

we really

need

your help.

HAFA ADAI JOAQUIN


Sure, I would be happy

to help

you two with anything.

Yahhh!,

what do

you do at

home to

help?

Go check Si John S.,

I think he is at home

We are trying to find

out how the kids of

Saipan, Tinian, and

Rota can help control

NPS Pollution.


Hey John,

Joaquin said

you would

show me how

to prevent

NPS

Pollution.

Oh, yes Clarence. It is very important

to clean up after your pets first of all.

Once these droppings get into the

water, all sorts of sicknesses can

happen. Make sure you do not touch it

though.


First of all, if your pets are

sniffing and eating other

animals waste, they will get

sick, so you should clean

up as soon as possible.

Secondly, These wastes can

get carried into the ocean

after a big rain storm and

cause all the fish and coral

to get sick, or carry

diseases that can get

humans very very sick.

One common disease is

ECOLI

BACTERIA!!!


Oh yeah, Dina

the Dolphin and

I have been

feeling sick

lately. Do you

think it was from

animal waste?

Maybe, but there are many other

pollutants around the house. Let me

show you this picture of the other

household wastes that can get into the

water and ocean.


Paint, Paint Thinner, Spray Bottles,

Aerosol Cans, Drain and Oven

Cleaners, Used batteries from

radios and cars, used oil, and any

other things that contain toxic

chemicals need to be disposed of

during the Household and

Chemical Waste Drive that DEQ

has every year in Saipan, Tinian

and Rota. These need to be stored

away from rain or water until they

are collected by the Division of

Environmental Quality (DEQ).


Man, you really

have a lot of

information

John. How can I

remember all

this?

O.K. I’m

ready.

Feed me

some

questions!

Well Clarence, let me give you

and our viewers some

Hi Students,

I am Clarence. I am really happy

that you watched our adventure. I

really hope you learned how to be

safe with all things that you use

every day.

The water supply, lagoons and

reefs really need to be protected

from pollution so I hope you will

tell a friend, your parents, and

your family what you learned

today. Help around the house and

be responsible for the environment.

If the humans can protect their

environment, the seafood we eat

and marine animals that we love

will be healthy and safe. That will

be more healthy for you kids and

your family. See ya at the beach,

bye.
