The Secret to Sleeping for Three Years
Move over Sleeping Beauty, snails might be just the next
Disney princess.
Did you know that snails can take naps for as long as three
years in hibernation or estivation? So the next time you wish for a bit more
shut-eye after long hours of work, you may consider wishing to be a snail in
your next life.
There’s a catch though. A snail’s three-year sleep is mainly
caused by extreme weather conditions.
Snails need moisture to keep kicking (or crawling…?) so if
the weather is too hot, too cold, or too dry, they would either hibernate
(during winter) or estivate (sleep during summer). To let the warm and cool
climate pass, they can sleep for up to three years.
During this time, the snail goes back into its shell,
releases as much moisture as possible from its body, and seals the opening of
its shell with a cellophane-like layer called an epiphragm, to protect
themselves from harsh climates. Some snails even wake up after estivating for
70 years!
Good for them, honestly. I, too, would want to hibernate
when I cannot take unbearable, external conditions. Except without myself covered
in mucus.
When they’re not sleeping for years, snails generally sleep
on and off in between 13 to 15 hours a day. Once they have finished their
regular sleep cycle, they will be filled with enough energy to get their snail
activities done and finished for the next 30 hours.
Oh to be a snail…
Trying to sleep for 3 hours,
