OWEN schreibt Ăźber insekten There are over one million insect species identified so far, but scientists believe there are about 30 million species estimated to exist on Earth. All insects have a similar body type. They all have three main body sections (the head, the thorax, and the abdomen) and six legs.

WHAT IS THE LIFE CYCLE OF AN INSECT? All insects have the same life cycle. They begin as eggs, hatch into larvae, pupate, and finally emerge as adults. Most insects lay eggs near the food they will eat after they hatch. For example, butterflies lay their eggs under leaves, which the larvae will eat. When the larvae hatch from their eggs, their job is to eat and grow bigger and bigger.

Once a larva has grown enough, it forms a cocoon to protect itself, and inside the cocoon it changes completely. This process is called metamorphosis. Finally, the pupa hatches as an adult insect.

WHAT KIND OF INSECTS LIVE IN THE RAINFOREST? Insects are the largest of all animal groups in the world. They are also the most diverse animals in the rainforest and the world.

Some types of insects include beetles, ants, butterflies, flies, stick insects, and many more. Some insects are strange-looking, some are brightly colored, and some are scary-looking. Many insect species are found in the canopy layer, which is the treetop level of the rainforest.

FUN FACT: Scientists once found 700 species in one tree in the rainforest. Here are some examples of interesting rainforest insects:

It covers over two million square miles.

The Amazon Rainforest is beautiful in different ways, like its colors and flora and fauna, which means plants and animals.

4. Fun Amazon Rainforest facts: - The Amazon Rainforest is home to 10% of the known species in the world.

- The droughts in 2005 and 2010 destroyed huge amounts of vegetation in the areas worst affected.

2. How many plants and insects are there in the Amazon Rainforest ?

- There are over 40,000 different kinds of plants and 2.5 million insects in the Amazon Rainforest.

5. Did you know?

HOUSES OF THE RAINFORESTS

Tropical rainforests are forests with tall trees, warm climate, and lots of rain. They are home to many indigenous populations that live in very unique houses, and rely on their surroundings for food, shelter and medicine.

Many people live in these rainforests, and their homes vary from houses like ours to small huts. Most houses in the Australasian Rainforests have basic infrastructure like electricity, water, sewer, and roads. Other rainforests like the Congo River Basin Rainforest don’t have any basic infrastructure.

Congo River Basin Rainforest House Rainforest areas in the world (green)

There are six areas in the world that have rainforests: South America, Central America, Congo River Basin, Madagascar, South East Asia, and Australia. The largest rainforest in the world is the Amazon Rainforest in South America.

Australasian Rainforest House

The rainforest houses are unique because of the environment they are in.

Most areas don’t have infrastructure (roads, electricity) to bring materials like cement, tiles, etc., so people must find materials nearby to build their own houses. They are often are made of palm leaves, trees, and clay.

The climate is mostly the same every year: hot and humid year-round. Since there is no electricity, there is no air conditioning. Ventilation is important because of the high heat and humidity. The houses have few walls, and the windows or wall openings in one end must be aligned to the windows/openings in the other end so that there is a wind tunnel in the house.

Wind tunnel are like air conditioning

Rainfall in the rainforest is about at least 200 cm per year (the size of a tall person); as a comparison, rainfall in San Francisco is about 63 cm per year (the size of up to the kneecap of a tall person). To keep rainwater from going inside the house, the roof must have a steep slope. Because the soil gets so much rain it can cause floods, so it’s important to build the houses elevated, lifted by stilts, to protect from floods, or animals trying to get into the house.

Stilts protect from floods and animals

Since hot air rises, it’s also important to build a house with a high ceiling so that the hot air has space to go up and not disturb the people living in the house.

Rainforest peoples have found a way to make their houses unique to their environment. Even though their homes are simple, have no electricity and are made with limited materials, they are comfortable because they learned how to build a house that works in the rainforest. If we lived in the rainforest in our own homes it would be very uncomfortable because the ceilings are low, the windows don’t create wind tunnels, they are not built on stilts, you will get very hot and maybe bugs will crawl up your legs!

And did you know that some orchids can shoot pollen? Some such as “catasetum fimbriatum” have mechanisms for shooting You can see this in this video, really cool! pollen at their pollinator!

Most plants are now cultivated from seed.

However, wild orchids are still endangered because of the small number of individual plants in each species.

I interviewed Eric Sayles, the Vice President of the San Francisco Orchid Society.

Where do most orchids grow?

They mostly grow in the mountains in the tropics and about at 7000 and 8000 feet. There you wear clothes like in San Francisco because of the similar weather and fog clouds. That’s why San Francisco is such a good place to grow orchids.

Why did you learn about orchids?

Because they symbolize raw nature.

When do orchids bloom the most?

In the bay area they bloom in the summer months, in the tropics they bloom in the winter.

Since when do orchids exist?

Orchids are newer plants in terms of evolution.

What makes orchids different from other flowers?

Orchids can climb on trees and grow on them.

When did you learn about orchids?

I learned about orchids when I was around 18 years old.

HIKING TRAILS PLITVICE LAKES NATIONAL PARK KAYA schreibt Ăźber hiking trails

1. Where is it?

The Plitvice Lakes are in Croatia in Eastern Europe. There are sixteen lakes connected by 90 waterfalls. You can walk between them on boardwalks.

2. How long is it?

You can take a short hike of 2.2 miles or a long hike up to 11.4 miles.

3. Why is it famous?

If you hike in the mountains you can see brown bears and wolves. If you hike near the water you might see a water snake.

A Long time ago there was a movie filmed there named Winnetou.

When Covid-19 is gone I want to go there on vacation with my family.

KAYA schreibt über ihre erfindung

Hi, my name is Kaya.

When I grow up I want to be a scientist.

I’m going to live in an apartment in Braunschweig.

My apartment is going to be 2,000 miles long because of one of my inventions, the lengthening spray. I also will have lots of other inventions, like paint that makes things invisible and a wall that can’t stop singing. And the lights in my house are also one of my cool inventions, if you are telling a lie and you’re standing underneath it it will start buzzing.

I also bought a run down apartment that cost 5$, but what I did was I put clean up water on it and it was squeaky clean! Next I put lengthening spray on, then I put on mansion eggs and SPLAT! Everything looked like a brand new mansion!

In my big mansion apartment I will have a pet baby sheep that can wander around wherever he likes.

His favorite place is the indoor garden, and when he wants the roof of it disappears.

My next invention will be the house builder!

This will make homeless people have houses, and construction people won’t have to breathe in the bad air! All you will have to do is put your finger in the liquid (purple) and think of your dream house and POP! It will appear right in front of you!

THE LARGEST LIVING TREE About 180 million years ago the earth was much warmer than it is today.

Dinosaurs roamed the forests then.

The first sequoia trees began to grow.

Around 25 million years ago, sequoias were growing all across North America and Europe. But during the last million years the earth has cooled.

The sequoias began to die.

Today, sequoias grow naturally only in California. They grow on the western side of the Sierra Nevada Mountains, living with other trees and plants.

The red spots on the map show where the giant sequoias grow.

Sequoias are found in groups called groves. Only 75 groves still exist.

INTERESTING PARTS OF A TREE TRUNKS AND BRANCHES Trunks and branches have many layers. The outer layer is called the bark.

The sequoia’s bark can get up to 2 feet thick. It is also fire resistant. However, if the bark burns the fire can leave black stripes on the bark called burn scars.

FROM SEED TO TREE Adult sequoias make about 2,000 new cones each year. There are female and male cones. Sequoia cones are the size of and the shape of chicken eggs. Up to 300 seeds fit inside of each cone.

During the winter a yellow powder called pollen bursts out of the male cones. The pollen drifts in the wind.

Some of the pollen reaches the female cones. This is called pollination. Seeds start to grow inside the female cones.

A few years go by before the seeds are ready to grow on sequoia trees.

leon schreibt über giant sequoias

Giant Sequoias Let’s figure out how many seeds are on a sequoia tree: 2,000 x 300 = 600,000 So 600,000 seeds a year!

By the way, it takes 91,000 seeds to weigh one pound.

Let’s figure out how many pounds of seeds are in a sequoia: 600,000 : 91,000 = approximately 600,000 : 90,000 = 60 : 9 = 6 R3 So approximately 6 pounds of seeds are on a sequoia each year!

FOREST FIRES Forest fires are important to sequoias.

Nearly every summer thunderstorms blow across the Sierra Nevada. Lightning often starts ground fires. A thin layer of ash from the fires covers the seeds. The ash helps the seeds grow.

Fires burn the forest understory. The understory is the smaller trees and plants that live in the shade of taller trees. After the understory dies, the sequoia seeds cannot grow better. They do not have to share the water and good soil with other plants.

DEATH OF A SEQUOIA Most old sequoias die after they fall over in a powerful wind or snowstorm.

Sometimes, fires weaken the tree’s roots.

Sequoia bark does not burn easily though. It protects the tree from most fires. Bark helps the tree from most fires and helps sequoias live a long life.

But some fires are so hot that a sequoia’s trunk does burn!

The burn scars after the fire can cut off water from the roots to other parts of a tree. Often the rest of the tree keeps

INTERESTING FACT Many scientists believe that experts should start fires from time to time to burn the understory.

In spring the seeds are ready to grow.

The tiny trees called seedlings, push out of the soil. By late summer or fall, the seedlings are 1 to 2 inches.

As the sequoias grow hundreds of roots spread cut just a few feet below the soil.

For the first 250 years, sequoias look like upside down ice cream cones. Then their trunks begin to turn red. When they are 500 to 700 years old, sequoias reach their height. Most of the low branches break off. The trunks are bare for 100 to 150 feet, or more. As the sequoias grow older, sequoias grow bigger branches, and thicker trunks. Sequoias can live up to 3,000 years old!

growing. When a part of the crown dies, the tree is called a snag-top. Many sequoias look strange because they are snag-tops.

A large sequoia crashing into the ground shakes the earth. Part of a dead sequoia might lie on the forest floor for hundreds of years.

Spiders, mice, birds, squirrels and other small animals make homes in the roots of bigger branches. Woodpeckers drill for ants and other insects.

Fires burn through the forest. Little by little the tree becomes part of the soil.

The tree gives vitamins back to earth.

Nearby plants grow in the rich soil.

FAMOUS SEQUOIA TREES

General Sherman, Sequoia National Park, CA The tree is not only the largest sequoia, but it is also the biggest tree in the world. It is more than 30 meter thick and 84 meters high.

The Pioneer Cabin Tree, also known as The Tunnel Tree, was a giant sequoia in Calaveras Big Trees State Park, California. It was considered one of the U.S.’s most famous trees, and drew thousands of visitors annually.

People made the tunnel to go through.

It is trying to recover itself with sap.

INTERESTING FACTS ABOUT SEQUOIAS 1. Are sequoias really the oldest in the world?

2. Are sequoias the tallest trees?

3. Can sequoias get extinct?

Answer: Yes, they could if people keep cutting down sequoia forests.

Grizzly Giant, Mariposa Grove, CA The tree is 28 meters thick. Its height is around 63 meters.

2. No, sequoias are not the tallest either. That distinction belongs to the sequoia close relative the coast redwoods.

3. Yes, they could if people keep cutting down sequoia forests.

Herr zwick eby schreibt über jadav payeng

JADAV PFLANZT EINEN DSCHUNGEL Jadav Payeng lebt in Indien.

Indien ist ein großes Land auf dem asiatischen Kontinent. Die meisten Menschen in Indien sprechen Hindi und Englisch. Insgesamt werden jedoch über 100 Sprachen gesprochen.

Jadav “Molai” Payeng wurde 1963 in der Region Assam geboren. Durch Assam fliesst der Brahmaputra. Das ist einer der längsten Flüsse der Welt: Der Brahmaputra ist 3100 Kilometer lang und an manchen Stellen bis zu zehn Kilometer breit!

Jadav wohnt auf Majuli. Das ist die größte Flussinsel der Welt: Die Insel liegt nicht im Meer, sondern ist vom Fluss Brahmaputra umgeben. Als Jadav ein kleiner Junge war, bestand diese Insel bestand nur aus Sand. Es gab keine Pflanzen. Und da die Sonne in Assam oft sehr heiss brennt, gab es auch fast keine Tiere.

Die Majuli-Insel wurde jedes Jahr kleiner. Warum? Weil der Brahmaputra den sandigen Boden einfach wegwäscht.

Eines Tages könnte die Insel Majuli völlig verschwinden!

“Ich muss etwas tun!”, dachte sich Jadav.

Deshalb begann Jadav, Bambus in den Sand zu pflanzen.

Bambus wächst schnell und spendet Schatten. Und seine Wurzeln halten den Boden zusammen. Der sand wird also nicht mehr so schnell vom Wasser weggewaschen!

Jeden Tag pflanzt Jadav mindestens eine Pflanze.

Seit mehr als 40 Jahren!

So hat Jadav ganz allein einen riesigen Dschungel gepflanzt. Die Menschen nennen diesen Dschungel “Molai-Wald”. Und Jadav Payeng ist heute berühmt.

Willst Du mehr wissen?

Dann lies eines der Bücher über Jadav Payeng!

In Jadavs Dschungel leben heute auch viele Tiere! Es gibt dort manchmal 100 Elefanten! Und Jadavs Dschungel ist die Heimat von Nashörnern, Rehen, Affen, Hasen, Geiern, vielen verschiedenen Waldvögeln und Insekten und sogar Tigern geworden!

Jadav Payeng sagt: “Auch Tiere aus der Ferne haben von meinem Wald erfahren. Ich weiß nicht, wie sie es herausgefunden haben. Aber sie kamen aus hunderten von Kilometern Entfernung in meinen Dschungel.“

ALL ABOUT ELEPHANTS

Elephants have always fascinated me because they are playful, smart, and strong. For centuries people have used elephants in warfare, logging, and entertainment.

First I will show you the differences between the African and Asian elephant. After that you will discover how smart elephants are. Finally you will learn about a unique body part of the elephant and its function. Can you guess what it is?

Now get ready to learn about elephants!

African Elephants

The two main types of elephants are the Asian and the African elephant. You can tell them apart by their physical appearance. On one hand the African elephant has bigger ears, bigger tusks, and a bigger trunk. On the other hand the Asian elephant has smaller ears, smaller tusks, and a smaller trunk.

The African elephant has a smooth head while the Asian elephant has two bumps on its head like a two humped camel.

Asian Elephants

Jenny and Shirley never forgot eachother.

Hey Google!

What is self-awareness?

“Self-awareness is the ability to focus on yourself and how your actions, thoughts, or emotions do or don’t align with your internal standards. If you’re highly self-aware, you can objectively evaluate yourself, manage your emotions, align your behavior with your values, and understand correctly how others perceive you.”

Elephants are one of the smartest land animals in the world. They can paint and they can kick a soccer ball in the net. Exceptional memory and self awareness in particular show that elephants are intelligent.

The story of Jenny the elephant illustrates how excellent an elephant’s memory is. When Jenny was a baby elephant she met an older elephant named Shirley in the circus. Both elephants only spent a few months together before they were separated.

By chance Jenny’s and Shirley’s paths crossed again 23 years later in an elephant sanctuary. Both elephants recognized each other immediately.

Animal keepers at the sanctuary described how both elephants displayed extraordinary affection towards each by making an unusual amount of noises due and using their trunks to caress each other. It was truly a heartwarming sight.

In addition to their phenomenal memory elephants also possess self awareness which is a rare feature in the animal kingdom. Scientists proved that elephants have self awareness. For the mat test the elephant was given the task of giving a stick to the researcher while standing on the mat.

Sometimes the stick was tied to the mat making it more difficult for the elephant to pass the stick to the researcher. The elephant was able to figure out that it had to step off the mat in order to be able to give the stick to the researcher. The mat test successfully demonstrated that elephants have self awareness.

Apart from their intelligence it is the elephant’s trunk that distinguishes the elephants from other animals.

The trunk is a very useful and strong body part which contains 40,000 muscles. In comparison the entire human body only has 639 muscles. The trunk is very strong and can lift up to 300kg. Humans have tamed elephants and used their strength to lift heavy logs for construction for many generations.

The trunk is not only exceptionally strong but has many other amazing attributes including a very delicate sense of touch. While the trunk can lift a very heavy log, it can also hold a peanut at its tip like humans do with their fingers. An elephant’s sense of touch is so fine that they can feel ridges that are only 0.25 mm small. Elephants are also very social animals and use their trunk to express their feelings and emotions.

Another fascinating thing about the trunk is the way it can smell. Elephants can smell water from about 20 km away. Their sense of smell is so great because they possess a large number of smelling genes. Elephants have 5 times more smelling genes compared to humans and 2 times as many smelling genes compared to dogs. Bloodhounds are famous for using their keen sense of smell to track down prisoners that have broken out of jail. But did you know that elephants have a sense of smell that is 4 times better than that of a bloodhound?

Did you like my article?

I hope you learned about the African elephant and don’t forget about how intelligent they are. Also remember about their very awesome and useful trunk! If you still want to see these magnificent animals in the future, you have to protect the elephants. Scientists say that elephants could be extinct by 2040. So please help the elephants, so the world can still see these wonderful creatures.

Leyna hat das Vincent van Gogh-Museum in Amsterdam besucht:

Ich finde den Museum von außen toll, weil es rund ist und eine Seite aus Glas hat. Drinnen sieht es eher langweilig aus, weil es nichts Besonderes ist.

Auf diesem Bild sehe ich einen großen braunen Baumstamm.

Unten sehe ich eine kleine Stadt mit einer Kirche in der Mitte. Im Hintergrund sehe ich Berge mit einem schönen Nachthimmel und einen leuchtenden Mond mit vielen Sternen. In der Mitte sieht es so aus, als ob der Wind weht.

Die Farben leuchten sehr, van Gogh hat viel Dunkelblau und ein leuchtendes Gelb benutzt.

Das Bild heisst “The Starry Night”. Vincent van Gogh hat es im Jahr 1889 gemalt.

Das Bild heisst “Skull of a Skeleton with Burning Cigarette”.

Vincent van Gogh hat es im Jahr 1885-86 gemalt.

Der hat eine Zigarette im Mund und ist ein Skelett. Ich glaube, er ist vom Rauchen gestorben. Und meine Oma hat dieses Bild bei sich zuhause.

Besuche das Vincent van Gogh-Museum in Amsterdam!

Der Hintergrund ist ganz schwarz. Es zeigt einen Totenkopf. Die Knochen sind weißgelblich. Nur der Kopf und die Schulterknochen sind zu sehen. Er hat noch alle Zähne und eine brennende Zigarette steckt zwischen seinen Zähnen.

Ich kann sehen wie die Sterne leuchten und wie der Wind weht.

Ich fühle mich sehr unruhig wenn ich mir das Bild anschaue.

Wenn ich mir das Bild angucke, dann fühle ich mich, als wäre ich im Bild drin. Ich fühle, als wäre ich auf einem ganz großen Berg und dass ich die Stadt von oben ansehe.

Das Bild heisst “De pastorie te Nuenen”. Vincent van Gogh hat es im Jahr 1885 gemalt.

Glaciers

Did you know that a tiny snowflake can turn into a Glacier? Yes it can!

Once the swirling flakes fall to the ground and clump together, they turn into a pack of snow and ice and air bubbles. And as more and more snow falls the weight of the snow and ice becomes heavier and heavier. It takes thousands of years for a glacier to form.

Glaciers give shelter to penguins, ...

A glacier is made out of ice.

IMPORTANCE OF GLACIERS

... snow foxes, ...

Glaciers are important for the health of our climate. They control the planet’s temperature and the sea levels. They give shelter to many animals like polar bears and penguins and other animals. Glaciers are found in the Antarctic, Greenland, Canada, Alaska, Austria, Switzerland and Iceland.

WHAT IS A CREVASSE?

A crevasse is a glacier that has fallen apart and if you fall in one you mostly don’t get out. Glaciers can be deadly.

... seals and other animals.

TYPES OF GLACIERS

There are many types of Glaciers: ice sheets are the largest type of Glaciers and the Antarctic has the biggest ice sheet in the world. Ice caps are massive ice mountains that bury other mountains.

An iceberg is a broken off piece of a glacier in the sea that can be very dangerous for ships like the Titanic. It sank after hitting an iceberg. 2,000 people died.

The Titanic sank from a piece of a glacier.

Glaciers are melting. We need to help!

WHAT ARE MORAINES?

Moraines are piles of rock on the edge of the Glaciers.

Glaciers are my favorite kind of mountains because they are made out of ice and you can ski on them. They are important to planet Earth. But now they need our help.

They are melting at a fast rate.

We are the only people who can stop the glaciers from melting. They are very important for the human race to help regulate our climate making it comfortable for us to live here on Earth. The polar bear’s homes are getting destroyed and we have to stop climate change. We must stop them from melting by not using our car too much and don’t fly that much. Instead of flying you can use the train or if it is not vacation you can ride your bike to the grocery store. PLEASE!!!

Belugas haben eine hohe Stirn

Was fressen Belugas?

Belugas sind Feinschmecker und mögen die Abwechslung. Sie futtern gerne Muscheln, Krebse, Tintenfische, Dorsche und Lachse.

Nachwuchs bei den Belugas Nach vierzehneinhalb Monaten bringt das Weibchen meist ein Junges zur Welt. Bei seinen ersten Atemzügen wird es noch von der Mutter über Wasser gehalten. Bis es zwei Jahre alt ist, trinkt es noch Muttermilch. Danach bleibt es noch zwei Jahre bei ihr.

Wie groß und wie alt wird ein Beluga?

Belugas messen drei bis sechs Meter und wiegen bis zu 1500 kg.

Belugas werden 35 bis 50 Jahre alt.

Warum haben Belugas so eine große Stirn?

Die Stirn der Belugas besteht nur aus Fett.

PUFFERFISH

leyna schreibt über Kugelfische

I think Pufferfish are interesting animals, because they look so funny.

Here are some questions I’m going to answer: - Are Pufferfish always puffy?

- Are Pufferfish dangerous?

- What do Pufferfish eat?

- Will you die when you eat Pufferfish?

- Where do Pufferfish live?

Puffed up

2. ARE PUFFERFISH DANGEROUS? Almost all Pufferfish are poisonous to humans. There is no antidote (which means that there is no medicine for the poison).

Normal

1. ARE PUFFERFISH ALWAYS PUFFY? Pufferfish will puff up to protect them self if they are threatened.

They will become twice as big as their normal size and round, and sometimes they are covered in spikes. This is much more difficult to bite and isn’t very tasty to an enemy.

They do this by filling their stomach with water and air.

Puffed up with spikes

3. WHAT DO PUFFERFISH EAT? The diet of Pufferfish includes mostly animals that don’t have bones, and algae (a plant in the ocean). Large Pufferfish will even crack open and eat clams, mussels and shellfish with there hard beaks.

Where pufferfish live Tiny guy

4. WHEN YOU EAT PUFFERFISH DOES IT KILL YOU? Pufferfish contain a very strong poison called Tetrotoxen, and eating it can kill a person. But if a chef cuts it exactly in the middle, where there is no poison, then you can eat it.

5. WHERE DO PUFFERFISH LIVE? There are 120 kinds of Pufferfish. They mostly like to swim in warm waters in the ocean (see map).

After learning a little bit about Pufferfish, would you want to see one in real life?

DEEP SEA LIFE

Deep sea creatures can be both interesting and VERY dangerous. Some do not hurt people at all, and some could kill a human.

But you do not have to worry about them hurting you because they almost NEVER come out of deep water because that could mess up their breathing.

THE BLOBFISH

2. THE HADAL ZONE Marine life decreases with depth, both in abundance and biomass, but there is a wide range of metazoan organisms in the hadal zone, mostly benthos, including fish,sea cucumber, bristle worms, bivalves, isopods, sea anemones, amphipods, and gastropods.

The blobfish is a type of fish that lives in the midnight zone in the ocean (see chart). The blobfisch is harmless (but a little bit ugly ;D). They live so deep under the surface that they could not survive at the surface of the water. They would burst like a balloon.

WHAT ARE THE LEVELS OF THE OCEAN? There are about 12 levels of the ocean and the ones where the animals I am writing about are in a few of the deepest levels.

Here are the names of them: 1. THE ABYSSAL ZONE is where the Anglerfish, deep sea jellyfish, deep sea shrimp, cookiecutter shark, tripod fish, and abyssal octopus also known as dumbo octopus.The animals that live in this zone will eat anything because food is very scarce down this deep in the ocean.

3. THE MIDNIGHT ZONE All other living things in the midnight zone are nourished by these bacteria. Living things in the midnight zone include: angler fish, tripod fish, sea cucumber, snipe eel, opossum shrimp, black swallower, and vampire squid.

THE SLOANE’S VIPERFISH

My favorite fish: Sloane’s viperfish, Chauliodus sloani, is a predatory, mesopelagic dragonfish found in deep-pelagic waters across the world. The species was first described by german scientists Marcus Elieser Bloch and Johann Gottlob Schneider in their 1801 book Systema ichthyologiae: iconibus CX illustratum, volume 1.

Its size can range from 64 mm to 260 mm, and it is an iridescent silverblue color. It has two rows of photophores, one on each side of the ventral part of its body. It is believed that C. sloani adjusts the intensity of ventral photophores during diurnal migrations to camouflage itself from predators that might see its shadow from below.

WHY DEEP SEA FISH CAN’T THRIVE AT THE SURFACE OF THE WATER:

The bodies of deep sea fish are adapted to super high pressure and if they come to the surface, then their bodies can’t work in the low pressure.

FUN FACT:

DEEP SEA SHRIMP Did you know that creatures in the abyssal zone use light to catch their prey? Pretty cool!
