Natural disasters must also be defeated by the intelligence of spiders in Australia

Australian spiders are forming spider spells, covering many areas with a thick layer of spider silk.

Many people think that Australia is a dangerous country, especially the natural world here. They own the world's most poisonous snakes or meter-long pythons. Even the dreamy beaches, just need to stop your feet, you can die of some dangerous fish there. Of course that's just a fun comparison.

However, many people still believe that this is true, at least after seeing this phenomenon.

Phenomenon of spider rain - many spiders spread silk and flew everywhere.

This is the phenomenon of "spider rain" - when thousands, tens of thousands, spiders spread silk and fly everywhere, causing the land to be covered with spider silk.

This phenomenon happened in Goulburn, New South Wales state of Australia in May 2015 and again covered a large area of ​​the country's city of Tasmania with spider silk. This is a way for spiders to survive even when a natural disaster has just occurred.

The spiders flew in the air and threaded.

Ballooning , also known as "kite flying" , is how spiders or some other small invertebrates use to move quickly in the air.

They will use their threads, shoot them out into the air above and use the wind to take them away. However, the death rate when using this method is quite high.

They will use their threads, shoot them out into the air above and use the wind to take them away.

The spider will climb to the highest possible location, aiming the abdomen of the body to the sky and adjusting so that it achieves the highest high magnification.

From there dropping his thread at such a great speed that the thread would drag it into the sky, sending it through a long distance in the air by relying on wind power.

Usually only small spiders with body mass below 1mg can ballooning.

Usually only small spiders with body mass below 1mg can ballooning. However, researchers have observed adult Stegodyphus spiders - weighing more than 100mg and body size up to 14mm - still using this move on a hot, windless day.

The distance the spider travels can vary from a few meters to hundreds of kilometers.

The distance the spider travels can vary from a few meters to hundreds of kilometers. Even people have obtained ballooning spider silk at an altitude of nearly 5km above sea level, or in ships in the ocean.

Many sailors reported catching ballooning spiders while being 1,600km from the mainland. It can be seen that this is the way the spiders often use to "invade" isolated islands and isolated peaks.

Spiders can build the ability to survive a lack of food for 25 days, even more.

But doing "expeditions" with such a long and long distance, for ballooning spiders will really be a "life" trip. Therefore, they build their own ability to survive a lack of food for 25 days, even more.

However, the phenomenon of "rain spider" is a completely different event. When millions of spiders are ballooning for a while, the threads will intertwine, making an entire area covered with spider webs as shown below.

When millions of spiders perform ballooning for a while, it is a rare natural phenomenon.

According to many experts, this is a rare phenomenon. So it can be said, the spiders in Australia seem to have learned to adapt to the waves of disasters, even if they are forest fires or floods.
