海牛下目

海牛下目（学名：Doridoidei；旧作Doridacea）是裸鳃目海牛亚目之下的一个下目级分类单元，皆为没有螺壳的海洋腹足纲软体动物^[1]。

型态描述[编辑]

The outer mantle bears caryophyllidia or sensory tubercles, surrounded by spicules.

在2005年的布歇特和洛克罗伊的腹足类分类，现在的海牛下目在当时只是有角鳃类海牛亚目之下的一个亚支序，包括下列四个总科与科^[2]。

海牛总科 Doridoidea Rafinesque, 1815
- Family Dorididae
- Family Actinocyclidae
- 多彩海麒麟科 Chromodorididae^[3]
- Family Discodorididae
Superfamily Onchidoridoidea Gray, 1827（= Phanerobranchiata Suctoria）
- Family Onchidorididae
- Family Corambidae
- Family Goniodorididae

在2017年的布歇特等人的腹足类分类，海牛下目及其所属的海牛亚目改为直接隶属裸鳃目^[5]^[1]。
