The springs bubbling with hot water were surrounded by an abundance of creatures that were hard to see with the naked eye. The smallest among them might only measure a few micrometers, and the largest only one or two millimeters. In the scalding hot springs, they lived quite contentedly and happily.
"Huh?" Suming was startled, actually coming across tardigrades!
No wonder they could survive in the boiling hot springs!
Tardigrades are nearly mythical creatures, and if Earth were to be destroyed, leaving only one animal to carry on, it would definitely be the tardigrade!
It is the strongest known survivor on Earth. This little thing that looks like a silkworm pupae, which dates back to the Cambrian period 500 million years ago, has evolved to become extremely small over time. It has eight chubby, round legs and a layer of water film covers its body, which when observed under a microscope, reveals its comically endearing manner of crawling along.
