'''Philinoidea''' is a [taxonomic](/source/Taxonomy_(biology)) [superfamily](/source/Taxonomic_rank) of sea slugs, specifically headshield [slug](/source/slug)s, [marine](/source/marine_(ocean)) [gastropod](/source/gastropod) [mollusk](/source/mollusk)s in the order [Cephalaspidea](/source/Cephalaspidea).<ref name="WoRMS">MolluscaBase eds. (2021). MolluscaBase. Philinoidea Gray, 1850 (1815). Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=196322 on 2021-10-14</ref>

==Anatomy==
The species in the Superfamily Philinoidea are generally small animals that have an internal or external shell, and a covered gill. Unlike some related forms, the [viscera](/source/viscera)l mass is not sharply set off from the rest of the body.<ref name=IZ>{{cite book |author= Barnes, Robert D. |year=1982 |title= Invertebrate Zoology |publisher= Holt-Saunders International |location= Philadelphia, PA|page= 376|isbn= 978-0-03-056747-6}}</ref>
