| 説明 | Pomacea sp. - apple snail shell (modern) from Florida, USA. (apertural 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 apple snails are a group of freshwater gastropods. This apple snail shell is from Florida, where one native species and several invasive / pest species are present. This empty shell was collected in December 1988.Classification: Animalia, Mollusca, Gastropoda, AmpullariidaeLocality: near Manatee Spring, near the eastern side of the Suwanee River, northwestern Levy County, near the Gulf Coast of Florida, USA (vicinity of 29˚ 29' 22" North latitude, 82˚ 58' 37" West longitude)--------------------------------------See info. at:en.wikipedia.org/wiki/Pomacea |
