Which animal can sleep for up to three years? Explained
Snails have the ability to slumber for as long as three years by undergoing a dormant phase known as estivation (to evade heat and dry conditions) or hibernation (to evade cold temperatures). Throughout these extended periods of rest, their metabolic rate decreases to preserve moisture and energy. In order to shield itself, the snail produces a dense layer of mucus that solidifies into a protective barrier, sealing its shell’s aperture. This natural defense aids in averting dehydration and warding off predators. Upon the return of favorable weather, the snail effortlessly dissolves the barrier and resumes its activity.
