海麒麟總科（學名：），或作海蛞蝓總科、海牛總科或隱鰓海牛超科，是海牛亞目海牛下目之下四個總科級分类级别之一，在生物分类学屬於裸鰓目（舊作隱鰓目）的海洋腹足綱軟體動物。

語源
海牛總科的學名源於海牛屬；而海牛屬的學名又源於希臘神話的海怪寧芙多里斯。

分類

1997年分類

根據1997年《旁得和林德伯格的腹足類分類》所列出的分類，海牛總科亦作仿海牛總科，是後生腹足下綱後鰓目裸鳃亚目類花鰓類次目（Anthobranchia ）的成員，包括下列四個科。
 总科 仿海牛总科 Doridoidea Rafinesque, 1815
 总科 Doridoxoidea Bergh, 1900
 总科 Onchidoridoidea Alder & Hancock, 1845
 总科 Polyceroidea Alder & Hancock, 1845

2005年分類
在2005年《布歇特和洛克羅伊的腹足類分類》，現在的海牛下目在當時只是有角鰓類海牛亞目之下的一個亞支序，包括下列四個總科與科。
  Dorididae
Family Actinocyclidae
 多彩海麒麟科 Chromodorididae
  Discodorididae

2005年之後的變更
Cadlinidae科 在2005年的分類被視為多彩海麒麟科的異名；但在R.F. Johnson (2011)的研究顯示Cadlina並不屬於多彩海麒麟科，所以這個屬不應再歸屬於多彩海麒麟科，而是應該獨立成為一個科。而多彩海麒麟科在踢走了Cadlina之後成為了單系群，很可能是Actinocyclidae的姊妹分類單元。2017年《布歇特等人的腹足類分類》亦加入了這個修訂。

科
，WoRMS紀錄本總科包括下列五個科：
 Family Actinocyclidae 
 Family Cadlinidae 
 多彩海麒麟科 Chromodorididae 
  Discodorididae 
  Dorididae 
 科地位未定
 Subfamily Miamirinae

以下分類單元曾被認為是異名，現在重新使用：
 星被海牛科 Asteronotidae 
 Baptodorididae

跟原來的隱鰓目的差異

隱鰓目被認為是海牛總科的異名：
Cryptobranch dorid nudibranchs (previously known as the taxon Cryptobranchia), are nudibranch sea slugs within the clade Doridacea. These slugs are called "cryptobranch," meaning "hidden gill", because they are able to retract their gills into a gill pocket, in contrast to nudibranchs in the traditional group phanerobranchs (or Phanerobranchia), which taxon is probably paraphyletic (in other words, composed of more than one evolutionary lineage).

A. Valdés distinguishes two major clades within the Cryptobranchia: the dorids that have no radula (the Porostomata); and those with a radula (the Labiostomata). The Labiostomata include the monophyletic families: Actinocyclidae, Chromodorididae, Dorididae and Discodorididae.

The cryptobranchs include the following genera that are regarded as valid : 

Doris Linnaeus, 1758
Asteronotus Ehrenberg, 1831
Atagema  J. E. Gray, 1850
團鰓海牛屬 Jorunna 
Discodoris Bergh, 1877
