腹足纲

腹足纲(学名:Gastropoda)是软体动物门中重要的组成部分,包括通常所说的蜗牛、海螺和蛞蝓。是软体动物门中最大的纲,约60,000到80,000生存种。包括约409个现生的科,另外还有约202个化石科。是动物中仅次于昆虫纲(Insecta)的第二大纲。

头部发达,腹面有肥厚而广阔的足,所以得名;身体有内脏的部分扭转,因此左右不对称;外面有介壳一枚或无壳。

生活在海水中的被称为海螺或海蛞蝓,生活在淡水中的被称为田螺或螺蛳,以及生活在陆地上的蜗牛和蛞蝓。

绝大多数的腹足纲的物种都具有一个呈螺旋形的“壳”,当遇到危险的时候会将柔软的身体缩进壳中。也有一些壳退化消失或仅在体内残留,通常被称为蛞蝓。
