This should be a cockroach, the ancestors of cockroaches and other insects were first evolved from arthropods such as sea scorpions and crabs on the bottom of the sea, and they are saprophagophagoes that like to lie dormant and live in burrows. It has withstood the test of extreme heat and cold, and is still quite widely distributed today. Cockroaches are one of the oldest insects on the planet and once lived in the same era as dinosaurs.

According to fossil evidence, primitive cockroaches appeared on Earth about 400 million years ago in the Silurian period. The fossils of cockroaches that we find or the cockroaches we find in coal and amber are not much different from those found in the cupboards. Its appearance has not changed much over the centuries, but its vitality and adaptability have become more and more tenacious, and it has multiplied to this day, widely distributed in all corners of the world.

Now scientists have reached a consensus that the most vigorous animal is the bear insect Italian zoologist Lazzaro Spallanciani also began to study this invertebrate (millimeter long) that can only be observed under a microscope in the 70s of the 18th century. Bear insects can only live in humid environments, such as fresh water, wet soil, tree trunks, rocky mountains, and well-watered moss and lichens. Once the water is insufficient, the bear bug enters a state of suspended animation.

It's hard to imagine that 100 years later, a dried bear insect can be resurrected with just a drop of water. In extremely harsh conditions, it can be said that only the bear insect has the strongest vitality. Studies have shown that bear bugs that enter a state of suspended animation can withstand freezing of minus 271 for several hours, can also tolerate short-term temperatures of minus 150, and can also withstand large amounts of radiation and high pressure.

How powerful is the water bear that has the strongest known vitality in the biological world?
