Thank you @airyearthgirl for inspiring me to gif these amazing lines
For six months I attended classes about them. You can bake them and they will survive. Super cute and powerful creatures 💞
THIS IS A TARDIGRADE APPRECIATION POST
Journey to the Microcosmos: Tardigrades: Chubby, Misunderstood, & Not Immortal
Reshare as I just posted another beau piece today :^D
Did I Make The Tardigrade?!?? 🧬🐻❄️🧪
Tardigrades are poisoning the theme park's water supply!!!!! Country BEAU Jamboree!!! Scientific intervention!!! Posted this to twittur dot com a little while ago; tis a pencil & paper illust I casually worked on these past few months. Usually illusts don't take me this long but would only chip away on it while I wasn't home (i.e. at coffeeshop & library). Character in the dead-center is my little freak Beau. They love the theme park's tardigrade mascot. Perhaps a little too much

Tough as a Tardigrade
Without water, a human can only survive for about 100 hours. But there’s a creature so resilient that it can go without it for decades. This one millimeter animal can survive both the hottest and coldest environments on Earth, and can even withstand high levels of radiation. This is the tardigrade, and it’s one of the toughest creatures on Earth, even if it does look more like a chubby, eight-legged gummy bear.
Most organisms need water to survive. Water allows metabolism to occur, which is the process that drives all the biochemical reactions that take place in cells. But creatures like the tardigrade, also known as the water bear, get around this restriction with a process called anhydrobiosis, from the Greek meaning life without water. And however extraordinary, tardigrades aren’t alone. Bacteria, single-celled organisms called archaea, plants, and even other animals can all survive drying up.
For many tardigrades, this requires that they go through something called a tun state. They curl up into a ball, pulling their head and eight legs inside their body and wait until water returns. It’s thought that as water becomes scarce and tardigrades enter their tun state, they start synthesize special molecules, which fill the tardigrade’s cells to replace lost water by forming a matrix.
Components of the cells that are sensitive to dryness, like DNA, proteins, and membranes, get trapped in this matrix. It’s thought that this keeps these molecules locked in position to stop them from unfolding, breaking apart, or fusing together. Once the organism is rehydrated, the matrix dissolves, leaving behind undamaged, functional cells.
Beyond dryness, tardigrades can also tolerate other extreme stresses: being frozen, heated up past the boiling point of water, high levels of radiation, and even the vacuum of outer space. This has led to some erroneous speculation that tardigrades are extraterrestrial beings.
While that’s fun to think about, scientific evidence places their origin firmly on Earth where they’ve evolved over time. In fact, this earthly evolution has given rise to over 1100 known species of tardigrades and there are probably many others yet to be discovered. And because tardigrades are so hardy, they exist just about everywhere. They live on every continent, including Antarctica. And they’re in diverse biomes including deserts, ice sheets, the sea fresh water, rainforests, and the highest mountain peaks. But you can find tardigrades in the most ordinary places, too, like moss or lichen found in yards, parks, and forests. All you need to find them is a little patience and a microscope.
Scientists are now to trying to find out whether tardigrades use the tun state, their anti-drying technique, to survive other stresses. If we can understand how they, and other creatures, stabilize their sensitive biological molecules, perhaps we could apply this knowledge to help us stabilize vaccines, or to develop stress-tolerant crops that can cope with Earth’s changing climate.
And by studying how tardigrades survive prolonged exposure to the vacuum of outer space, scientists can generate clues about the environmental limits of life and how to safeguard astronauts. In the process, tardigrades could even help us answer a critical question: could life survive on planets much less hospitable than our own?

congrats to the tardigrade for winning invertebrate of the year 2025!!
So, the tumblr upload of this video got deleted for being “sexual explicit”. I tried reporting it as a mistake a few days ago but have received no response. I don’t really like putting the youtube layout on tumblr, but i do want to complain.
