Physa aridi is a fossil species of air-breathing freshwater snail, an extinctaquatic pulmonate gastropod mollusk in the family Physidae. This species has a small, left-handed (or sinistral) shell, as is always the case in this family. Physa aridi dates from the Senonian (Upper Cretaceous) of the Bauru Group, in São Paulo state, Brazil.[1]
