According to one study snails may sleep for up to three years at a time [1]. That’s a very long time to be asleep! But why do they sleep for so long?
There are a few theories. One is that snails need to conserve their energy. They move very slowly so they don’t use up a lot of energy during the day. By sleeping for long periods of time they can save their energy for when they need it.
Another theory is that snails need to protect themselves from predators. If they’re asleep they’re not moving so predators can’t find them. This theory is supported by the fact that snails are more likely to sleep during the day when predators are more active [2].
Whatever the reason it’s clear that snails sleep for a very long time!
