背楯亚目

背楯亚目(学名:Notaspidea),原作背楯目,是海蛞蝓的一个人工分类群组,现时已经被分成两个互不相关的群组:伞螺目及侧鳃目(Pleurobranchmorpha)[1]。从2018年起,本分类被认为是裸侧类支序之下的侧鳃目(Pleurobranchida)的异名[1]。
分类学变更历史
[编辑]本分类原最初由1883年由法国动物学家保罗·亨利·费舍尔设置,当时包括侧鳃海牛属(Pleurobranchus)及伞螺属(Umbrella)两属,并归类于覆鳃类(Tectibranchiata)之中[2]。4
背楯类物种包括有海蛞蝓和一种被称为“假笠贝”的海洋腹足纲软体动物的分类,直腹足亚纲后生腹足下纲后鳃目的成员。然而,在较新的2005年布歇特和洛克罗伊的腹足类分类,the families Umbraculidae and Tylodinidae belong to the superfamily Umbraculoidea Dall, 1889, part of the clade Umbraculida. Grande et al. (2004) found Umbraculoidea to be a sister clade to the Cephalaspidea (Acteonoidea excluded).[3]
The families Tylodinidae and Umbraculidae have large limpet-like external shells and a small mantle, while the species in the family Pleurobranchidae have a prominent mantle and an internal shell that becomes reduced or is lost in adults.[4] Many species produce mantle secretions as a chemical defense against predators [5]
由于侧鳃科与伞螺科并不具单系性,因此两后来被拆分,本分类元也于被处理为侧鳃目(Pleurobranchida)的同物异名[2]。
科
[编辑]本亚目包括下列三个科:
- Tylodinidae J.E. Gray, 1847
- 侧鳃科 Pleurobranchidae Menke, 1828
- 伞螺科 Umbraculidae Dall, 1889
