The Sunlight Zone
Hi! Im a Mola mola, also called a
sunfish. My name is Sunny
because I like bathing on the top
of the water in the sun. Mola
molas range from 6 to 10 feet
long and like to eat jellyfish.
My friends and I are going to take
you on a tour of the five zones of the
ocean! The first is the sunlight zone,
then the twilight zone, then the
midnight zone, the Abyss and last, the
Trenches.
2
I live in the sunlight zone (the prettiest and most
wonderful place!). The sunlight zone is the smallest
zone, but it has the most life. Some of the animals
that live here are snails, sharks, dolphins, whales, sea
turtles, jelly fish, (of course Mola molas!) and many
others. Some of the plants here are seaweed and
coral. Coral is formed by polyps’ skeletons. Many
things live in or on coral and eat things off it. Sea
anemones attach to coral and when a fish swims by,
the anemones kill it with their poison tentacles.
That’s why I never go near them!
3
The Sunlight zone is also called the Epipelagic zone.
The Sunlight Zone
The temperature of the sunlight
zone ranges from 80°F to 27°F
depending on where the ocean is.
44
In Antarctica, the water
would be around 27°F
and in the Caribbean, the
water would be around
80°F
5
The Sunlight Zone
The sunlight zone goes from
the surface down to about 200
meters. Then it becomes the
twilight zone. The sunlight
zone has the most oxygen in it
because it is closest to air.
6
Now we have gone through
the AMAZING sunlight
zone! I cannot go down
any further, so my great
friend, Jaws will tell you
about the next zone, the
Twilight zone.
7
The Twilight Zone
Hi. I’m Jaws. I will guide you through the Twilight zone. I’m hungry. My species is dark green or grey and is 3-6 feet long.
Bye!
The Twilight zone is also called the Mesopelagic (mez-oh-puh-lajic) or Midwater zone. The Mesopelagic zone means, loosely translated, meso: middle and pelagic: relating to the open sea. The Midwater zone nickname is originated from meso. Of course, all the animals call it the Twilight zone because the other names just aren’t scary enough, especially for fear-inducing, fabulous animals such as me.
8
A scrumptious fact about the Twilight zone is that it’s partially dependent on marine snow, which comes from the above layers and occurs in all the zones. Marine snow is made of dead animals, plants and sand. It’s called snow because it’s white and falls slowly. The need for marine snow increases in each zone as there are no plants in most zones. That means all animals below the Sunlight zone are carnivores or scavengers. The base of the food web is marine snow.
9
The Twilight Zone
Many animals here are bioluminescent (bio-loom-en-es-ent), or produce their own light, like a firefly does on land. Also many creatures have long, pointy teeth...like my killer ones!
10
Jaws: I’m now going to interview Ms. Luna Flash, a flashlight fish, also a tasty morsel whom I really want to eat. So, Ms. Flash, how have you adapted to life here?Ms.Flash: Well, I’m
bioluminescent, but I can turn
my light on and off. I’m so
special! And how dare you
want to eat me!
Jaws: Um...can’t think of a question...umMs.Flash: This conversation is so boring... bye bye!
Jaws: Grrrrrr...
11
The Twilight Zone
The temperature in the Twilight zone varies greatly. This zone extends from 200 meters to 1,000 meters, and the depth is the main factor in
temperature. The temperature has a range of 56℉
to 39℉. The pressure doesn’t effect many creatures as they’re adapted to it. Also, there is very little oxygen. And... I really want to scare something!
12
The Twilight zone is the transition from a light, warm zone (which is totally boring compared to this incredibly scary zone, right?) to the dark zone below it. This marks the end of the Twilight zone. Squish, whom I also want to eat, is your next welcoming (maybe) tour guide, to the Midnight zone.
13
The Midnight Zone
Hi Jaws, Please don’t eat me!
I’m a sea cucumber. My name is Squish. I live
partially buried under the sand or on it. I’m like a
soft cucumber.
No plants live here because there is no light and it
isn’t warm enough for them.
14
Not very many animals live here but a few are Lantern
fish, Giant Squid, Vampire Fish, and Sea Sponges.
Most of the fish here are blind or have large eyes.
Some even have huge mouths so they can grab marine
snow or fish swimming past. Most fish here also have
weak muscles because there is no need to swim fast.
The reason is there aren’t many predators here. Some
fish have slimy bodies like me.
15
The temperature in this zone is
about 39° F. This may not seem
very cold but in fact it is.
Freezing is 32°F. So it is almost
freezing!
The midnight zone
16
Another name for the
midnight zone is the
bathypelagic zone. Its called
the midnight zone because its
midnight black down here.
17
The midnight zone
The reason is because this Zone
extends from 1,000 to 4,000
meters, so no sunlight reaches it.
The Midnight zone has immense
water pressure that increases with
depth and has very, very little
oxygen.
18
This is the biggest zone. Of course, the fact that
this zone is so big doesn’t affect me as I mostly stay
in one place. This is the longest I’ve crawled ever!
This is the end of the incredible
Midnight Zone. Hope you enjoyed the
tour! This zone is the best, isn’t it?
Soon you will meet Clementine, your
next host.
Abyss
19
Hi, my name is Clementine. I am called Clementine because I am a
yellowy-orange color. I am a Dumbo octopus and I live in the abyss.
I am eight inches tall and I love to hover above the ocean floor.
20
My zone has 3 names. The first (and easiest to say) is the abyss. The
second name for my layer is the abyssal zone. And if you want to be
scientific you can call it the Abyssopelagic zone.
The name the abyss comes from the Greek word meaning “no
bottom” because the Greek thought the ocean had no bottom.
How funny is that!
Abyss
21
The temperature in the abyss is usually freezing. The only exceptions are
crazy places called hydrothermal vents. They shoot boiling hot water into the
ocean above.
22
There is almost no life here in the abyss, except for
outside of the hydrothermal vents.
Abyss
23
Hydrothermal Vents are
like fountains on the sea floor.
They are found at an average
depth of 7,000 feet. The
Hydrothermal Vents are one
of the only places in the
Abyss to find life. There is no
oxygen and no light in here.
Tube worms and huge clams are the
dominant creatures in the vents in the Pacific
Ocean. Tube worms get their food from the
billions of bacteria inside them. Tube worms
cant eat food because they have no mouth,no
stomach, no intestines, and no way to poop. The
Bacteria turns the chemicals in the water into
food for the tube worms. Eyeless shrimp are
only found in vents in the Atlantic Ocean.
Animals live on hydrothermal vents because of
the heat from the vents and the chemicals they
release.
24
There are two
different kinds of
hydrothermal vents.
The first kind are
called black smokers.
They are the hottest
kind of vent. The
second kind are called
white smokers. They
shoot cooler water
into the ocean above.
Hydrothermal vents are formed by the earths tectonic
plates moving and making cracks in the ocean floor.
The water gets heated by the magma below the
earth’s crust .
The Trenches
25
There are these really scary black holes below me in some parts of
the ocean, called trenches, that I am scared to go near. But one
day I did. I went to one of the deepest ones, called the Challenger
Deep. Let me tell you about it. You might think it was impossible to
live down there because there is no light; It is really cold, and it is
suffocating due to lack of oxygen. But you would be wrong. At the
bottom of the Challenger Deep scientists found one-celled organisms,
called foraminifera I wish I could see one! They are little one-celled
planktons and they can live there.
26
The trenches have three names. The first you
know: trenches. The second name is the hadal
zone, and the third name is the hadalpelagic zone.
Whatever you want to call this zone it is 19,700
to 35,797 feet deep. There can be up to 8 tons
per square inch of water pressure on you when you
are in the Marianas Trench, the deepest one. The
temperature in only slightly above freezing.
My friends and I have now taken
you through all the zones of the
ocean! I hope you enjoyed our
other world!
