| 説明 | Ficus gracilis (Sowerby, 1825) - graceful fig snail shell, abapertural view (10.3 cm tall), modern (latest Holocene).This is a graceful fig snail shell (a.k.a. elongated fig snail shell), Ficus gracilis (see photo of living snail inside the shell - www.zukan-bouz.com/makigai/bansokurui/sonota/biwagai.imag...). This is a modern, predatory, tropical marine gastropod from the western Pacific Basin that inhabits unconsolidated sand substrates and preys on irregular echinoids. The shell itself is relatively thin & lightweight. Classification: Animalia, Mollusca, Gastropoda, Neogastropoda, Ficoidea, Ficidae----------------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. |
