This is a tardigrade aka Water Bear. It is the most extreme extremophile discovered to date. It can survive temperatures of -459F to 304F, can withstand 1000 times more radiation than any other known creature, can be re-hydrated after 10 years without water and can survive the vacuum of space. Hot damn.
Paramacrobiotus craterlaki. Tardigrades are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of close to absolute zero, or 0 Kelvin (−273 °C), temperatures as high as 151 °C, 1000 times more radiation than other animals and almost a decade without water. Since 2007 tardigrades have also returned alive from studies in which they have been exposed to the vacuum of outer space for a few days in low earth orbit
Water bear (Paramacrobiotus craterlaki). Coloured scanning electron micrograph SEM). Tardigrades are microscopic animals commonly known as water bears In 2007, a little known creature called a tardigrade became the first animal to survive exposure to space. It prevailed over sub-zero temperatures, unrelenting solar winds and an oxygen-deprived space vacuum. On Monday, this microscopic cosmonaut has once again hitched a ride into space on the Nasa shuttle Endeavour.
Meet the toughest animal on the planet: The water bear that can survive being frozen or boiled, float around in space and live for 200 years. Tardigrades, strange 200 year old creatures survive in space & extreme radiation. They can survive temperatures as low as -457 degrees F, heat as high as 357 degrees F, and 5,700 grays of radiation, when 10-20 grays would kill humans and most other animals.
Water bears are able to survive the most extreme environments that would kill almost any other animal. They can take temperatures close to absolute zero and hotter than boiling water, withstand over 1000 times more radiation than humans, can live over a decade without water, endure six times the water pressure in the deepest ocean trench, and even survived in the vacuum of space, making them the only animals to do so.
New record: World’s oldest animal is 507 years old / "The pattern in Ming’s growth rings does not only provide scientists with an accurate age of the animal; the A. islandica can also provide a unique insight into past climate conditions. By examining the various oxygen isotopes in the growth rings, scientists can determine the sea temperature at the time when the shell came into being."
