【树螺科】
树螺科（学名：Helicinidae），又名螺科、䗉蜗牛科TaiBNET_314314或无脐蜗牛科shelldoc_000050，是软体动物门腹足纲之下的一个科，旧属蜑螺总科（Neritacea），今独立出来成为树螺总科之下唯一的一个科。本科的物种在其壳口均有厣可封盖其壳。皆为陆生。
虽然本科物种在外表跟陆地上呼吸空气的蜗牛很相似，但其实在分类学来说，两者的分歧颇大。
==分布==
本科物种的分布比较奇怪：牠们生活于热带及亚热带地区，但只限于加勒比海的岛屿及部份印度太平洋区及太平洋的岛屿，也在亚洲及澳大利亚大陆的边缘地区生活。
==分类==
===多样性===
本科估算约有770-1400个物种。
===2005年分类===
根据2005年《布歇特和洛克罗伊的腹足类分类》的分类，本科由蜑螺总科之下转为成立独立的一个总科。本科由六个亚科组成，分别如下：
* 树螺亚科 Helicininae Férussac, 1822：即 Olygyridae Gray, 1847 或 Bourcierinae Paetel, 1890
* Ceratodiscinae Pilsbry, 1927
* † Dimorphoptychiinae Wenz, 1938
* Hendersoniinae H. B. Baker, 1926
* Stoastomatinae C. B. Adams, 1849
* Vianinae H. B. Baker, 1922
