蛞蝓

，中国南方某些地区称，俗稱鼻涕蟲或無殼蝸牛，又稱水蜒蚰，是一类无壳的陆生腹足纲軟體動物，与同样陆生的蝸牛组成有肺目。蛞蝓雌雄同體，外表看起來像被摘除背壳的蝸牛《說文》稱：“附蠃背負殻者曰蝸牛，無殻者蛞蝓。”程瑶田《爾雅 · 释虫小记》谓“蛞蝓即螔蝓，与蜗牛为一物。”，體表溼潤有黏液，對农作物有害，但對人體無害。

食用價值
蛞蝓雖然可以食用，且味道和蝸牛無異，但因為外形對某些人會造成心理上的噁心，因此幾乎很少能見到人類去食用這類軟體動物；蛞蝓本身無毒無害，但牠為血線蟲的中間宿主，人類食用未100%煮熟的蛞蝓會被感染。

寄生蟲病
蛞蝓是萬年青屬植物的花粉傳授者，故在萬年青上常可見蛞蝓出沒。2010年，澳洲有一名19歲的橄欖球球員Sam Ballard，接受朋友的挑戰，生吞活蛞蝓後，感染「廣東住血線蟲」（Rat Lungworm）。該寄生蟲在囓齒動物身上發現，但蝸牛或蛞蝓在吃掉老鼠糞便時也會成為中間宿主。因此罹患了嗜酸性腦膜炎（eosinophilic meningo-encephalitis），導致終身癱瘓，于2018年病逝。
