Insecta are insects of the class Bug, which is part of the Hemiptera family. Entomologists call them true bugs. They have four legs, hair, and gills. You know their appearance, but did you also know that they also have other unique characteristics?
Insects can be classified as invertebrates
Invertebrates are bugs that have both living and nonliving parts. Insects can be segmented with exoskeletons of chitin. The three major units of their body are the head, abdomen and thorax. These body segments are used by insects to extract nutrients from food. They use catabolic processes to digest their food. This breaks down complex macromolecules of sugar into simple sugars.
They are four-legged.
It's interesting to see that not all insects have the same number of legs as others. For instance, locusts have four legs and butterflies six. Jumping is done by insects using their front pairs.
They have gills
Most people are likely familiar with the fact insects can have gills. They allow insects to breathe. They can also be used to view the environment around them. Most insects have many visual units. However, some species have complex eyes with hundreds of visual unit. For example, caterpillars have 12 eyes and 30,000 eye ommatidia.
They have hair
You should be aware that insects have hair. Insects are the most diverse group of animals, and their sheer population makes them an interesting group to study. Humans and non-entomologists both find insects fascinating because they play a significant role in the economy and environment. Here are some fascinating facts about bugs, including how they jump and what they eat.
They produce methane
Methane is a greenhouse-gas that is released by insects such as termites. These bugs produce methane in the intestines of their animals, and they are responsible to about 5 percent worldwide emissions. While methane is naturally occurring in the atmosphere, human activities account for 320 million tons of methane each year. Natural gas production is the largest source of methane.
They have ommatidia
Insects have compound eyes that are made up of seven to eleven visual units. They are used for a wide variety of purposes. Some insects have more than others. The wingless sandfish has less than 100 while the dragonfly boasts more than 30,000. The interesting thing about male insects is that they have more ommatidia then females. This makes them easily identifiable.
They have amazing body parts
One of the most diverse and varied groups of organisms on the planet is the insect family. They not only make a significant contribution to the economies in many countries, but they also offer fascinating experiences for both humans and nonentomologists. For example, did you know that a grasshopper has ears on its belly? In addition to this, its hind legs have special organs for jumping. In fact, the grasshopper can jump the length of a basketball court. They are also the first animals to produce sound, thanks to their incredible body parts.

What is the most mysterious area on earth?
Antarctica is the world's most mysterious place on Earth.
This is why we find it so captivating. Because it is unlike any other spot on Earth.
It is isolated, remote, and very hard to visit. It is not what you see.
You will also find some of the oddest wildlife species in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it refers to "land of ice". Others believe it comes from Greek mythology.
Antarktis in ancient Greece was the name given the island where Zeus' twin brother brothers were born. One of the twins was said to have been born in winter. Thus, the term antarctic.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would mean that the land was turned away by the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the coldest, windiest, driest and highest continent. Because it is so cold, there aren't any trees, plants or animals.
Yet, life is abundant in this frozen wilderness.
About 90 percent of all living things on Earth live here. About 50% of the world's plant and animal species can be found here.
What is Antarctica? Here, water freezes into ice instead of evaporating into the air.
This causes large amounts of ice to float above ground.
These floating glaciers cover over 80%. They continue to grow in size each year.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting continues, the sea level will rise by up to 200 feet. This could lead to massive flooding across the globe.
However, not all scientists believe this to be bad news. Some scientists think global warming might be beneficial. They say that as temperatures rise, the ice sheets might melt faster, causing floods that flush out tons of toxic chemicals from our soil and bodies.
Others cautioned that this theory sounds too science fiction.
Is there an Hollywood blacklist?
There is a Hollywood blacklist.
The list isn’t available for public viewing. The names are not known to us. Here's why this matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. They would go out of business which would mean that studios would lose their money. That would result in a reduction in spending on movies. This would result in fewer opportunities available for blacklisted filmmakers. This would make them bankrupt.
This could mean more victims.
When someone tries making an Oscar winning movie they might be asked for a contract. This means that they can't publicly criticize their employer. For any producer or director that wants to be nominated, the same applies.
You hear stories of directors being pressured to remove scenes from films. Directors may threaten to quit projects that don’t align with their vision.
This is why Hollywood has a blacklist. If you are negative about your employer, you'll most likely go unemployed. That's bad for everyone.
There are many people who have been falsely accused. These people have had to fight to clear their names.
We must stop this from happening again. We must ensure that everyone has the right to express themselves freely.
Also, we must take down the Hollywood blacklist.
What is the most secretive location in the entire world?
It may surprise you to hear the answer. It might even make you uncomfortable because it challenges our perception of reality and how we live. However, there's a reason for this place to exist. It's not what we would expect.
It was also called the City of God in ancient Greek. It was also called the City of Destruction in the Bible.
It's known in India as Kashi (Kashmir). It's also known as Novgorod in Russia.
Here in America, however, it is called The Village That Disappeared.
One tiny town in western New York State lost its 1,200 inhabitants without trace. There were no bodies, cars or houses left behind, but a road sign that pointed to the former location was all that was left.
This little community vanished and no trace remains to indicate where or when it disappeared. Some say the earth swallowed it up. Others claim that a meteorite hit destroyed it. Others believe that aliens took it.
The people of this once-thriving community, however, are positive that the town won't disappear forever. They had just moved from one town to the other.
A website is available to track the disappearance and recovery of Zugspitz, which was lost in the Great Depression.
The question is, where did this place go? It's in Switzerland.
Zugspitze lies on the border between Austria and Germany. The lake Lake Zugspitze is just beyond the mountain's summit.
I have always been fascinated by the fact that so many towns have vanished, but some remain. Why do some disappear while others survive? I decided to investigate.
I wanted to know more about the mysterious disappearing towns. What causes a community to disappear? How does one place go extinct?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory says that a town disappears when all the buildings are demolished. Another theory says that the town just moves. A third theory claims that the town never existed at all.
No matter what theories you may have, there is no doubt that many towns across the globe were swallowed by the ground. This video looks into the history of those places and investigates their current status.
