Waking up after Sleeping for 24,000 years – Part 1

Thursday, September 1, 2022

When I was kid, I knew the word of “hibernation” refer to “sleep” during cold (winter) season.

On that time, I just knew a bear as a perfect example of animal to do hibernation in short times, not years.


Actually, many other animals do hibernate in addition to bear, just few of them are:

- ground squirrels

- bats

- snakes

- turtles

Fig 03- Squirrel at backyard. Ground squirrel may hibernate.


In fact, due to many factors such as sudden changes in temperature and less food sources, animal (physiological) reacts by: lower heart rate, set down body temperature and relax metabolism


Recently, scientists found a bdelloid rotifer which had been slept for 24,000 (twenty thousand) years in Arctic, Russia. Very long sleep.


This multicellular organism (very small size, can’t be seen by naked eyes). The size is about 500 micron (0.5 mm).


What is surprising?

  7. In high school, I did a science project on rotifers found in bird bath water as a possible cure for leukemia. Thank you for the interesting and informative post. God bless you, Laurie
