Things You'll Need
- Plastic sheet
Instructions
Remove the snail and smell the foot. The foot is the small, flat portion right below the snail's body that acts as a "door" to the shell. The body will have a pungent, rotting odor if the snail is dead. They are normally odorless, although poor water quality could lead to a bad smell.
Pull the foot back gently. The snail is still alive if it retracts its foot back into its shell.
Set the snail on a plastic sheet outside the tank and watch it diligently. It will open its shell and begin to move around in search of water after a few minutes if alive. They have lungs that allow them to breathe outside of water, so the snail will not be harmed.
