海麒麟總科

海麒麟總科（學名：Doridoidea），或作海蛞蝓總科、海牛總科或隱鰓海牛超科flickr，是海牛亞目海牛下目之下四個總科級分類級別之一，在生物分類學屬於裸鰓目（舊作隱鰓目）的海洋腹足綱軟體動物Bouchet 2005。

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

**分類**

**1997年分類**
Peltodoris nobilis from Yaquina Bay
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鰓亞目類花鰓類次目（Anthobranchia Férussac, 1819）的成員，包括下列四個科Ponder 1997。- 總科 仿海牛總科 Doridoidea Rafinesque, 1815- 總科 Doridoxoidea Bergh, 1900- 總科 Onchidoridoidea Alder & Hancock, 1845- 總科 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Bouchet 2005。- Dorididae Dorididae
*Family Actinocyclidae- 多彩海麒麟科 Chromodorididaeshelldoc_000161- Discodorididae Discodorididae

**2005年之後的變更**
Cadlinidae科 small|Bergh, 1891在2005年的分類被視為多彩海麒麟科的異名Bouchet 2005；但在R.F. Johnson (2011)的研究Johnson 2011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Bouchet 2017。

**科**
，WoRMS紀錄本總科包括下列五個科WoRMS_173：- Family Actinocyclidae O'Donoghue, 1929- Family Cadlinidae small|Bergh, 1891- 多彩海麒麟科 Chromodorididae small|Bergh, 1891- Discodorididae Discodorididae small|Bergh, 1891- Dorididae Dorididae Rafinesque, 1815- 科地位未定

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 Thiele, 1931- Baptodorididae Odhner, 1926

**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 Bergh, 1876
*Discodoris Bergh, 1877
*Platydoris Bergh, 1877
