These amazing creatures can survive conditions that would kill any other living creature. In this article, we&#039;ll share 10 of the most astonishing facts about tardigrades that will make you look at the microworld in a completely new way.<\/p>\n<h2>What are tardigrades and where do they live?<\/h2>\n<p>Tardigrades are aquatic invertebrates ranging in size from 0.1 to 1.5 millimeters. They are also called &quot;water bears&quot; due to their distinctive gait and appearance. These microscopic creatures are found almost everywhere: in soil, moss, lichens, fresh and salt water, and in some of the most extreme environments on the planet.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-94707\" src=\"https:\/\/bukvaved.top\/wp-content\/uploads\/2025\/03\/chto-vam-nuzhno-znat-o-tihohodkah-samyh-vynoslivyh-sushhestvah-v-mire_67e4938964436.jpeg\" alt=\"\" width=\"1000\" height=\"600\" ><\/p>\n<h2>Fact 1: Tardigrades can survive in outer space.<\/h2>\n<p>Tardigrades&#039; most astonishing ability is their ability to withstand cosmic radiation and vacuum. In 2007, European scientists sent a colony of tardigrades into space for 10 days. Upon returning to Earth, many individuals not only survived but also successfully reproduced.<\/p>\n<p><strong>What makes this possible:<\/strong><\/p>\n<ul>\n<li>Resistance to cosmic radiation is 1000 times higher than that of humans.<\/li>\n<li>Ability to withstand a complete vacuum<\/li>\n<li>UV protection<\/li>\n<\/ul>\n<h2>Fact 2: Cryptobiosis is a state of &quot;temporary death&quot;\u00ab<\/h2>\n<p>Tardigrades have the unique ability to enter a state of cryptobiosis\u2014a complete halt in vital processes. They can remain in this state for decades, and under favorable conditions, return to life again.<\/p>\n<p><strong>The process of transition to cryptobiosis:<\/strong><\/p>\n<ol>\n<li>Loss of up to 99% of body water<\/li>\n<li>Slowing down metabolism to an undetectable level<\/li>\n<li>Curling into a defensive posture<\/li>\n<li>Formation of protective protein structures<\/li>\n<\/ol>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-94708\" src=\"https:\/\/bukvaved.top\/wp-content\/uploads\/2025\/03\/chto-vam-nuzhno-znat-o-tihohodkah-samyh-vynoslivyh-sushhestvah-v-mire_67e49389c4a41.jpeg\" alt=\"\" width=\"1000\" height=\"600\" ><\/p>\n<h2>Fact 3: Extreme Temperature Resistance<\/h2>\n<p>Tardigrades can survive in an incredible range of temperatures:<\/p>\n<ul>\n<li><strong>Low temperatures<\/strong>: up to -273\u00b0C (almost absolute zero)<\/li>\n<li><strong>High temperatures<\/strong>: up to +150\u00b0C<\/li>\n<li><strong>Normal habitat<\/strong>: from -40\u00b0C to +60\u00b0C<\/li>\n<\/ul>\n<p>This resilience allows them to survive in Arctic ice, hot springs, and other extreme conditions.<\/p>\n<h2>Fact 4: Radiation resistance exceeds all known limits<\/h2>\n<p>Tardigrades can withstand doses of radiation thousands of times higher than what&#039;s lethal to humans. The secret lies in their unique ability to quickly repair DNA damage.<\/p>\n<p><strong>Comparison of radiation resistance:<\/strong><\/p>\n<ul>\n<li>Human: 5-10 gray (lethal dose)<\/li>\n<li>Tardigrade: up to 15,000 gray<\/li>\n<li>Defense mechanism: Dsup (damage suppressor) proteins<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-94709\" src=\"https:\/\/bukvaved.top\/wp-content\/uploads\/2025\/03\/chto-vam-nuzhno-znat-o-tihohodkah-samyh-vynoslivyh-sushhestvah-v-mire_67e4938a19916.jpeg\" alt=\"\" width=\"1000\" height=\"600\" ><\/p>\n<h2>Fact 5: Ability to regenerate lost body parts<\/h2>\n<p>Tardigrades have amazing regenerative abilities.
