Tardigrades: Adorable Extremophiles

TL;DR

The Tardigrade, also known as a water bear or moss piglet, is the toughest animal on Earth and can survive in extreme environments, including space.

Transcript

Do me a favour right now and picture in your mind the toughest animal on earth whatever you think it is and now imagine what that animal would do in the most inhospitable environment that you can imagine so for example if you thought of a grizzly bear on top of Mount Everest being attacked by a swarm of silverback gorillas you would be wrong that i...

Questions & Answers

Q: What is the Tardigrade?

The Tardigrade, also known as a water bear or moss piglet, is a microscopic animal that can survive in extreme environments due to its ability to go into a dormant state.

Q: How can Tardigrades survive in extreme temperatures?

Tardigrades have the ability to withstand temperatures close to absolute zero and up to 300°F by entering a dormant state, protecting themselves from the harsh conditions.

Q: What makes Tardigrades resistant to radiation?

Tardigrades have the remarkable ability to withstand high levels of radiation, even 1000 times more than what would be lethal for an elephant. Their DNA repair mechanisms and protective proteins play a role in their radiation resistance.

Q: Why are scientists interested in studying Tardigrades in space?

By sending Tardigrades to space and exposing them to the vacuum and high levels of radiation, scientists can study how these animals survive in such inhospitable environments. It helps us understand the potential for life in space and supports the Panspermia hypothesis.

Summary & Key Takeaways
