Freshwater-, land-, or sea-dwelling is the way to classify a snail. Such a classification puts the snail in question in the gastropod class of the mollusc phylum within the animal kingdom. Another way of classifying a snail therefore will be as a gill-breathing creature of water-logged habitats or a lung-breathing creature of moist, but not water-filled, niches on land.
