Hi! The water bear - the Arnold Schwarzenegger of the micro bug world - raises a smile to the camera


Tardigrades are found everywhere. They are present within 100 meters of a person. They are indestructible. Importantly they are also called moss piglets or water bear.

Initially they are 1 mm in size, their length is 1.5 mm after growth. . They are aquatic invertebrates.


The Tardigrades belong to the kingdom Animalia. It is placed in Tardigrada phylum.

About 1150 species of tardigrades are found. Apart from this they are also known as slow stepperss.


They are one of the immortal creatures. According to scientists, they can also survive an asteroid impact.

They can live in adverse conditions. They can live under high pressure. Also in high temperature and low temperature conditions.

They can live up to 30 years without food. They can also live in and near volcanoes.

Eventually, the ultimate death of the sun can erase them.


In 2008, the European Space Agency (ESA) sent the Tardigrades into space. They managed to avoid cosmic rays and rather harmful UV rays which are 1000 times more powerful than Earth. They can survive to extremes conditions in vacuum. Also they are the first creatures. to do this.In addition, their DNA is used for advanced studies.

A type of protein found in them named Dsup, which protects DNA and cells from extreme conditions and desiccation. This gives rise to further advanced studies and experiments.

This DNA can be induced in humans.

As a result helping to protect humans from harsh conditions. People working in nuclear plants will get benefits to prevent themselves from radiation.


One study found that cells involving a human and a tardigrade cells were able to prevent up to 40% damage by X-rays.

It opens up new ways of treating cancer. People undergoing radiation treatment will have new expectations because prevention will be easier.

Cosmic rays and UV rays therefore it will provide more effective preventive methods for astronauts.
