Insecta refers to insects belonging to the Insecta class in the Hemiptera. Entomologists have classified them as true insects. They have four legs, hair, and gills. So, you know what they look like, but did you know they have other characteristics as well?
Insects make up invertebrates
Invertebrates refer to bugs as having both living and dead parts. Insects have segmented bodies and exoskeletons made of chitin. The main parts of their bodies are divided into the abdomen, head, and thorax. These body sections are used by insects for extracting nutrients from their food. They use catabolic reaction to digest their food, which breaks down complex macromolecules in simple sugars and provides amino acids.
They are four-legged.
It is interesting to note that some insects only have four legs, but others have six or more. For instance, locusts have four legs and butterflies six. Insects use their front pairs for jumping.

They have gills
Many people are familiar with the fact some insects have gills. They allow insects to breathe. They can also be used to view the environment around them. Some species have compound eyes that combine hundreds of visual elements. While most insects have eyes composed of multiple visual units, others have complex eyes. For example: Caterpillars have twelve sets of eyes and over 30,000 ommatidia.
They have hair
You should be aware that insects have hair. The most diverse animal group, insects, is the one that's worth studying. The role of insects in our environment is vital, as they are important for both human and non-entomologists. Here are some interesting facts about insects, including what they eat and how they jump.
They produce methane
Methane is a greenhouse-gas that is released by insects such as termites. These insects produce methane from their stomachs and are responsible for approximately 5 percent of the global methane emissions. Methane can be found in the atmosphere naturally, but human activities produce approximately 320,000,000 tons of methane annually. The fossil fuel industries, which include the production and use of natural gas, are the biggest sources of methane.
They have ommatidia
The compound eyes of insects are composed of seven to eleven separate visual units. They can be used to perform a variety different tasks. Some insects have a larger number of ommatidia than others. The wingless silverfish, for example, has less than 100 ommatidia, while the dragonfly, on the other hand, has more than 30,000. The male insects are distinguished by having more ommatidia (more than the females), which is quite interesting.

They have bizarre body parts
Insects make up one of the largest and most diverse species of organisms. Not only do they contribute to the economies of many countries, but they are also fascinating to humans and non-entomologists. One example is the fact that grasshoppers can have ears on their stomachs. In addition to this, its hind legs have special organs for jumping. The grasshopper can leap up to twice the length of an NBA court. The grasshoppers are not only amazing in their bodies, but they also sound like the first creatures to make sounds.

Ever wonder how much trash gets produced each day around the world?
The United Nations states that an average person produces more than 2.5 pounds of waste per day. That's over 25 billion pounds of garbage each year!
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? Where does all that rubbish go?Well, most of it gets shipped out of the country. It is then dumped in other countries, where it pollutes their ecosystems.But now, thanks to the work of one man, we know exactly where all this trash goes. His name is Mike Sexton. He is the founder of Waste Watchers. He watches over trucks that transport trash across North America. He reports back to us about the next steps.
Sexton said he enjoys his job. CNN spoke with Sexton that they have a lot fun. "We see big rigs coming through town and we'll follow them. "Sexton started following truck driver almost 20 years back.
He said, "I fell in love with it."
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton remembered, "The man was looking for somewhere to put the load." "He drove along the road and saw this structure. So he backed up and went inside. "There were two enormous roll-off containers filled with stuff. He took out everything and began to fill up the truck. "Then he looked at the place and decided to unload everything. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was just a total mess. But it was cleaned out before he came. There was no trash."
This is the reason why it happened. The answer is that this location was once part of a recycling facility. People who knew about it would drive to this location to recycle their garbage. Sexton said that people would bring their household items to the building and then leave empty containers behind.
This could happen hundreds of time per week. This can happen hundreds of times a week.Eventually, the truck becomes so overloaded with junk that it stops running. The owner eventually abandons the vehicle.
However, trash is not the only problem on our planet.
Plastic pieces make up most of these particles. Some end up in rivers and oceans, while others end up in fish's stomachs.
Experts say if nothing changes, we could soon face a global food shortage. Experts warn that if we continue to go the same way, we won't make it. However, scientists and most people aren't worried.
What is your most secretive community?
You might be surprised at the answer. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. However, there's a reason for this place to exist. It's not what we would expect.
The ancient Greeks called it the City of God. It was also known as the City of Destruction according to the Bible.
It's known in India as Kashi (Kashmir). It's also known as Novgorod in Russia.
It's called The Town That Has Disappeared here in America.
One small New York State town with just 1,200 people vanished. A road sign pointing to the former location of the town was all that was left, except for a few bodies and cars.
This little community vanished and no trace remains to indicate where or when it disappeared. Some say it was swallowed up by the Earth. Others say it was destroyed in a meteorite collision. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
Whatever happened, the residents of this once-thriving community are convinced that their town isn't gone forever. They just moved to another city.
There's even a website that tracks the disappearances and recoveries of Zugspitz.
The question is, where did this place go? It's actually in Switzerland!
The border of Austria and Germany is at Zugspitze. Just beyond the summit of the mountain is a huge lake called Lake Zugspitze.
It's always fascinated me how so many towns disappear, yet others remain. Why is it that some disappear while others live on? I decided that I would investigate.
I was interested in learning more about these mysterious towns that are disappearing. What makes a town disappear? How does one place go extinct?
It turned out that there are many theories about disappearing towns. One theory says that a town disappears when all the buildings are demolished. Another theory states that the town simply moves to another location. Another theory suggests that the town has never existed.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video examines the past and present status of these areas.
What is the most mysterious location on Earth?
Antarctica is the world's most mysterious place on Earth.
Why do we find this place so intriguing? It is unlike any other place on Earth.

Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is not known by anyone. Some believe it is "land of the ice". Others believe it derives from Greek mythology.
Antarktis was an ancient Greek name that was given to the island where Zeus and his twin brothers, Zeus. One of the twins was said to have been born in winter. The term antarctic is derived from this.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would mean land turned away from the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the driest, windiest of all continents. It is too cold for trees, plants and animals.
Yet, this frozen wasteland is alive.
It houses approximately 90% of all Earth's living organisms. You can find approximately half the world's species of animal and plant plants here.
What makes Antarctica so special? Here, water freezes and becomes ice instead of evaporated into the air.
This results in large masses of ice floating above the ground.
These floating glaciers cover over 80%. They are growing in size every year.
The Antarctic ice has grown 60 feet so far since 1960.
If the melting continues, sea level could rise up to 200ft. This could lead to massive flooding across the globe.
This is not necessarily bad news. Some scientists believe that global warming can 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.
