A snail can sleep for three years
The reason snails sleep are they alike many other animals hibernate. Most snails cannot last that long without eating and being active. Some only live for a year anyway. The few that can last more than a year without any activity tend to be long-lived species living in arid climates. It is normal for them to “aestivate” in the hot, dry summers, effectively going into a state of suspended animation until it rains. In real deserts the are a few that can survive in this state for several years. The authenticated record is 6 years for a species from Baja California in Mexico, and there are others that have been clocked at 5 years.
