INDEX

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.

CLASSIFICATION

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.

DEATH OF TARDIGRADES

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.

EXPERIMENTS

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.

MEDICAL FIELD

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.

Immortal animals found in earth

JELLY FISH(SEA JELLIES)

~ jellyfish ~

Organisms related to the phylum Cnidaria. They are found in deep oceans. Actually considered as immortal animal. Above all,they are mostly without brain and blood.

Almost every species is invertebrate. They can reproduce both sexually and asexually. Immortal animals like Territopsis dohrnii can start a new life cycle and is considered immortal.

Above all Jelly fish contain stem cells that can regenerate or renew cells.

PLANARIAN FLATWORM

The #planarian #flatworm doing its amazing dividing trick.

Immortal animals.In other words,they are flat worms belonging to the phylum platyhelminths. mostly carnivorous.

The experiment showed that the dissection of a flatworm from either of the two sides would produce two identical worms .

The whole body of two parts takes different ways. Pluripotent stem cells allow this.Here’s the video – https://www.youtube.com/watch?v=hTC1eNTBXvE

LOBSTERS

Immortal animals are very lucky, but eaten as seafood. They are truly immortal until fishermen catch them. related to the Phylum arthropoda.

An enzyme telomerase is present. It prevents DNA damage and helps in replication and renewal. .No built in life expectancy. Therefore,the cells are constantly renewed.

HYDRA

Louis Shalako: Hydra.

Considered immortal.These organisms have regenerative potential. They can breed in two ways. In other words sexually and asexually.

Hydra (plural for hydra) who die sexually and those who breed asexually remain immortal.

Also most of them reproduce by the budding which is actually asexual.

TARDIGRADES

One of my favorite creatures. These cute little ones are 1 mm in size. Above all, they can survive harsh temperatures, pressures and radiation. .

In conclusion death of a star can kill Tardigrades. Actually considered immortal animals.

In addition, a protein called Dsup is present in them. It helps in surviving harsh conditions
