Can snail live without food for one day?

Snails can actually survive without food for extended periods of time, even up to a year.

When there is a lack of food available, snails enter a state of dormancy or aestivation, during which their metabolic rate slows down significantly, allowing them to conserve energy. They seal their shells with a layer of mucus, reducing water loss and energy expenditure. In this dormant state, the snail relies on its stored energy reserves to sustain itself.
