Summary
editDescriptionMesodon sp. (land snail) (near Point Leavell, Kentucky, USA) (45962872075).jpg |
Mesodon sp. - land snail shell (modern) in Kentucky, USA. (apical view) The gastropods (snails & slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments. Most gastropods have a calcareous external shell (the snails). Some lack a shell completely, or have reduced internal shells (the slugs & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores. The shell shown here is a modern land snail - Mesodon sp. Mesodon snails are a group of pulmonates, which are air-breathing, terrestrial gastropods. Some pulmonates - the slugs - lack external coiled shells. Others have the same type of coiled, calcareous shell as freshwater and marine snails. Classification: Animalia, Mollusca, Gastropoda, Pulmonata, Polygyridae Locality; Point Leavell Outcrop - roadcut along (new) Route 52 at Old Railroad Road intersection, near the town of Point Leavell, southwest of Paint Lick, Garrard County, Kentucky, USA. (37° 35’ 37.09” North latitude, 84° 29’ 35.97” West longitude) More info. at: <a href="https://en.wikipedia.org/wiki/Polygyridae" rel="noreferrer nofollow">en.wikipedia.org/wiki/Polygyridae</a> |
