Gastropod species
Medium- to large-sized tropical freshwater snails. One species occurs naturally in Florida, and three others have been introduced. The family contains many genera and numerous species in South America, Central America, Mexico, Africa, and Southeast Asia. Frequently the shells of ampulariids and viviparids are very similar.24 thg 1, 2023 ...
