Do u know the snail can sleep three years? yeah, its a amazing fact. Snail is a very small animal in the earth & it mostly found in garden and fresh water.A snail have four tangles, two are large and the other two are small.Their eyes are on the large tentacles and smell receptors arre found on their small tentacles.A snail can find a place to sleep for up to three years until the climate is more suitable for them because snails can live for fifteen years & it is a good portion of their life. It is strange that this creature can sleep for three years and we must be astonished to know that a regular nap or sleep of a snail is one week. In the 21st century, science has largely abandoned the snail-in-a-drawer model of research, though we may never have a better idea of just how long a snail can sleep.
