| 説明 | Charonia tritonis (Linnaeus, 1758) - giant triton snail (apical view) (public display, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA)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.From museum signage:"Charonia tritonis (Linnaeus, 1758)Triton trumpetThis magnificent shell is traditionally used as a trumpet by the Polynesians and other Southwest Pacific peoples. It may reach 50 cm (20 inches). Living triton trumpets feed on the crown-of-thorns and other sea stars. A very similar species, the Atlantic trumpet triton, Charonia variegata, is found in the Caribbean Sea and Gulf of Mexico."Classification: Animalia, Mollusca, Gastropoda, Rannelidae---------------More info. at:en.wikipedia.org/wiki/Charonia_tritonis |
