Why Do Snails Sleep for 3 Years (The Science of Snail Hibernation)

Did you know that snails can sleep for up to 3 years straight? ​When weather conditions become too hot, dry, or freezing cold, snails enter a long state of dormancy (aestivation or hibernation) to survive. They seal themselves inside their shells using a layer of hardened mucus called an epiphragma and slow down their metabolism drastically to conserve energy. #snails #snailfacts #animalfacts #didyouknow #hibernation #aestivation #naturefacts #scienceshorts #wildlife #sleepfacts #interestingfacts
