涡虫纲
扁形动物门的一纲
涡虫纲(学名:Turbellaria)是扁形动物门一个纲,传统上包括所有非寄生的扁形动物物种,约有4500种,多数为自由生活的掠食者或食腐动物。涡虫纲包含陆生及水生物种,大多数涡虫为海生,在底泥、岩石、海藻上爬行;淡水涡虫生活在池塘、溪流的石块下;陆生涡虫大多为夜行性,栖息在落叶或腐木等阴湿处。涡虫体表具纤毛,摆动时积水呈涡状。大多行有性生殖,所有物种皆为雌雄同体。

分类
涡虫纲传统上包括所有扁形动物门之下的非寄生物种。但根据分子生物学证据,涡虫类已被证实为并系群,原来属于寄生物种的三个纲(吸虫纲、单殖纲和绦虫纲)都是涡虫类物种的直系分支,加上涡虫纲内有两个目独立成另一门,较新的文献已不再使用本分类。
大多数一般人接触最多的涡虫类物种都属于三歧肠目。2008年以后的研究确认了:无肠目和纽涡虫目其实并不属于扁形动物,而是属于独立的无腔动物;而链涡虫目的物种亦较早与其他扁形动物门的物种分化。这两个分类群在较新的文献已不再被认为是涡虫类物种。然而在医学寄生虫学,基本上仍然沿用旧有的分类。
传统分类
以下为传统的涡虫纲下属分类,可分为11个目:
- 无肠目 Acoela(现属无腔动物)
- 链涡虫目 Catenulida
- 单咽涡虫目 Haplopharyngida
- 卵黄皮目 Lecithoepitheliata
- 大口涡虫目 Macrostomida
- 纽涡虫目 Nemertodermatida(现属无腔动物)
- 多歧肠目 Polycladida
- 原卵黄目 Prolecithophora
- 原顺列目 Proseriata
- 棒肠目 Rhabdocoela
- 三歧肠目 Tricladida
