No matter where you look, you will find bugs surrounding you. The vast diversity of this species has enabled them the possibility to adapt to the animal world and successfully survive in it entirely. The insects have three parts of their body, head, thorax, and abdomen. Also, almost all insects have their hallmarks, antennas and pointed out eyes. Considering their basic body plan, they have managed to develop some of the most extraordinary abilities. So, here are the most interesting facts about them.
So far, the scientists have managed to discover more than 1.5 million of an animal in the world, making insects one-third of that amount. But, they have just barely scratched the surface, the studies indicate that there are more than one million insects yet to be discovered. Considering their small size and the speed of the bugs, they can easily hide and go undetected without consuming too much energy.
They are one of the largest group of insects, and more than 380,000 can be found in nature. That’s 40% of the entire population of insects. So, what is the reason for such biodiversity? Most scientists discovered that found the way to prolong their species and avoid extinction.
Planet of ants
When you are outside, realizing on a warm temperature, you can spot dozens of ants caring something. Ants live in colonies, and it is estimated that ten quadrillions live on the planet at this moment. Compared to humans, on one person goes 1.4 million of ants.
On every continent… not exactly right
Even though we can find insects everywhere on the Earth, there is just one place they can barely survive: Antarctica. In fact, only one species of insects can survive harsh winters in Antarctica. The so – called Belgica Antarctica lives on this continent; it is tiny, just barely 0.23 inches. It can survive on this continent because it freezes its body fluids.
One place the insects haven’t conquered
Beside the mentioned Antarctica, there is still one place which insects haven’t been able to inhabitant, the area that covers 70% of our planet: the ocean. No one knows the reason, but scientists suspect the lack of food and place for hiding, which land provides them.
Insects don’t use mouth to breathe, but still, they inhale oxygen and exile carbon dioxide. This whole process of breathing is developing through holes called spiracles. The interesting fact about breathing, their respiratory system isn’t connected to the bloodstream. Instead of this, they have a separate cardiovascular system of tubes, called a tracheal system, which helps them transfer oxygen to each cell in the body.
The oldest fossil discovered, a set of jaws, goes back 400 million years in the past, making the insects one of the oldest animals. This indicates that insects were wondering the Earth among the first animals. They were on land when animals made a transition from sea to earth. The insects were 170 million years before the dinosaurs on this planet.
