Water Bear! Terrible life force of the strongest creature in the earth and a micro Water Bear.
What is the strongest creature in this world? Is it a lion? Is it an ant? Are you man? There is strongest creature unfortunately no creatures meet. That's a Water Bear.Water Bear

The Water Bear animalcule 8 chairs which live in the micro world with a bear bug walk slow by a foot. Its form looks like a bear, so it's said to be a Water Bear. A calicoback of a beetle and not the creature's name of the element, but about 1000 kinds, I'm here, but it's generically called, it's called a Water Bear.
How will a bear bug do and introduce the one which is the strongest life form or the reason?
It's strongest by a temperature of Water Bear!1st of wonderful places by Mr. Water Bear is tolerance to the temperature. A human cell is precocious per 55 times and tolerant, but surprisingly, a Water Bear is also all right with 151 times of hotness.
When I say at a lower way, even absolute zero point (0.0075 kelvins) is endured mostly. The one which isn't understood well has come out of the K, but it's said that it's about− 273.15 ℃ by the limit which doesn't become cold any more. But, this, in dryness, the limit. I'm fine with 151 times of hotness, but I die of boiling water.photo by Bob Goldstein and Victoria Madden, UNC Chapel Hill
2 It's strongest dryly!The 85% is usually water, and Mr. Water Bear is made. But it's possible to be to reduce this water to 0.05% and enter in the inuimin state and live through juiceless dryness. Moreover it's the bear bug which doesn't have the long life to there and usually dies of 1 month-about 1 year, but when it'll be in this inuimin state, you can also live for 9 years.
3 It's strongest by the pressure!The space is airless. A Water Bear can live through such vacuum position, so it's confirmed that you can also live for about 10 days at space. 75,000 atmosphere can be even endured, so the deep sea is also easy!
4 It's strongest by radiation!The man's lethal dose such as the ultraviolet rays and the X ray is 500 roentgens, but it's also able to endure 570,000 roentgens in case of a Water Bear.
There are millions of creatures in the earth, but even if the environment changes this, the creature who can adapt himself is about a Water Bear.
When even if it's put in such intense environment, the inuimin state, state of apparent death and the shiomin state will be in the hibernation state, and I'll survive and it's the original environment, without what does it begin to move just as it is? Indeed creature suitable for the strongest name.
Whether Mr. Japanese Taiki Horikawa who advances a study by NASA can utilize its valuable special quality for something, you're always advancing a study.
A dramatic change may come in the earth for the mankind thanks to this Mr. Water Bearbear bug sometime..., I just think and have a dream.

クマムシ!地球最強の生き物、ミクロなクマムシの恐るべき生命力。
この世で一番強い生物はなんでしょうか?ライオンでしょうか?蟻でしょうか?人間でしょうか?残念ながら、どの生き物もかなわない最強生物がいます。それが「クマムシ」です。
クマムシとは、ミクロの世界に住む8脚の足でのそのそと歩く、緩歩動物。その姿が熊みたいなので、クマムシといわれています。カブトムシとか、カメムシとか単体の生き物の名称ではなく、1000種類ほどいるものの総称をクマムシと呼ぶのです。
クマムシがいかにして最強生命体なのか、その所以を紹介しましょう。
1 温度で最強!クマムシさんのすごいところの1つ目は温度への耐性。人間の細胞は55度あたりませ耐性がありますが、クマムシはなんと151度の高温でも大丈夫。
さらに低いほうでいうと、 絶対零度(0.0075ケルビン)までほぼ耐えられるのです。ケルビンよかよくわからないのが出てきましたが、これ以上冷たくならないという限界で、−273.15 ℃くらいだということです。ただし、これは乾燥状態に限り。151度の高温は平気ですが、熱湯では死んでしまいます。photo by Bob Goldstein and Victoria Madden, UNC Chapel Hill
2 乾燥で最強!クマムシさん、通常はその85%が水分で出来ています。しかし、この水分を0.05%まで減らし、乾眠状態に入ることで、水分のない乾燥状態でも生きることができるのです。しかも、寿命はそこまで長くなく、通常1ヶ月~1年ほどで死んでしまうクマムシですが、この乾眠状態になると9年間も生きられるのです。
3 圧力で最強!宇宙空間は空気がありません。クマムシはそんな真空状態でも生きることができるので、宇宙空間でも10日間ほど生きられることが確認されています。さらに、75,000気圧にまで耐えられるので、深海もへっちゃらです!
4 放射線で最強!紫外線やエックス線など、人間の致死量は500レントゲンですが、クマムシの場合は57万レントゲンにも耐えることができます。
地球には数百万の生き物がいますが、このように環境が変わっても適応できる生き物はクマムシくらい。
こういった苛酷環境におかれても、乾眠状態、仮死状態、塩眠状態、冬眠状態になり生き延び、そして元の環境になると、そのまま何事もなく動き出すのです。まさに最強の名にふさわしい生物。
NASAで研究を進める日本人の堀川大樹さんなどは、その貴重な特性を何かに生かすことが出来ないかと、日夜研究を進めてくださっています。
いつかこのクマムシさんのおかげで、人類に、地球に、劇的な変化が訪れたりするかも・・・考えるだけで夢があります。
