Water Bear Reproduces After Being Frozen For 30 Years
Researchers at the National Institute of Polar Research in Tokyo defrosted two tiny animals called tardigrade or “water bears” from a batch collected in the Antarctic in 1983.
One died after 20 days but the other began reproducing. It laid 19 eggs and 14 hatched successfully, reported The Asahi Shimbun newspaper.
The research occurred in 2014 but was just published last week. The longest survival rate for tardigrade had previously been nine years.
Tardigrade are really hardy creatures surviving extreme environments. From the BBC:
Tardigrades are often referred to as water bears because of their chunky bodies and bear-like claws. Despite their miniscule size, they are by all accounts one of the hardiest creatures on earth, surviving extreme heat, radiation and even a trip into space. They are able to slow down their metabolism until it practically stops, a process known as cryptobiosis, which enables them to withstand freezing.
