2006 ?夏秋?季在東沙島進?詳盡的?生軟體動物相調查，共紀?13 科26 種，其中4 科20 種為新紀?。多?種?發現活體與幼體，5 種舊紀?種分?誤植亦予以校訂。東沙島無特有種?生軟體動物，我們推測其種源應由鄰近地區自然擴散播遷或經人為引入。
A thorough field survey concerning the land molluscan fauna of the Dongsha Island in the South China Sea was conducted in summer and fall, 2006. Twenty-six species belonging to thirteen families of land snail were recorded. Of these, 20 species and four families are new records. Emendations of five species from the previous records were also made. Alive adults along with juvenile individuals were collected in most of the species. Since no endemic land snail species was found, we proposed that the plausible origin of these land snails might have dispersed from adjacent localities or via artificial introduction.
