Tardigrade moves like 'giant' insects;  The secret lies in physics - 12/09/2021

Scientific curiosity about the Tardigrades, Microbes that survive the extinction of the earth, Not from today. Post-study learning to understand their secrets and why they are resisted. In the latest of them, the researchers looked at their mobility – they have Eight legs about 0.5 mm long.

As a result, Tardigrades can move as fast as 500,000 times the size of insects. The information is from the scientific website LiveScience.


Also known as water bears, these microbes have divided bodies. As their name suggests, they live in water, but most impressively, they are very difficult to kill over 1,300 species.

They can survive extreme temperatures, solar radiation, and vacuuming.

How they move

According to the study, Published in the scientific journal PNASLittle is known about the movement of the Tardigrades. A team of scientists led by Jasmine Nirodi, a researcher at the Rockefeller University Center for Studies in Physics and Biology in New York, is working to examine the subject.

The Tardigrades were soon seen splitting locomotion attempts between the first six pairs of legs. Also, they can move well if the body is on a surface that can be dug and pushed with nails.

After analysis, the researchers found that one of these animals raises its limbs when it moves slowly, but uses three at the same time to achieve speed – one on the front and back on the same side of the body, and the other on the other.

This indicates that the Tardigrades are moving like this ArthropodsThat is, like spiders, locusts, and crabs. However, the study failed to define how one of the smallest animals in the world behaves like an insect much larger than them.

The first theory is that tardigrades and arthropods shared a common ancestor millions of years ago. However, scientists are also considering the possibility that this movement may have developed individually when their ancestral records were broken.

Nirodi explained that despite having completely different sizes, anatomy and locomotion environments, it is important to note that the shared motor coordination scheme between the two species is effective for both species.
