They are generally small animals, and have no shell or gills. Unlike some related forms, the visceral mass is not sharply set off from the rest of the body.[1]
Taxonomy
2005 Taxonomy
Families within the superfamily Philinoidea include (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):[2]
- Family Aglajidae Pilsbry, 1895 (1847)
- Family Cylichnidae - synonym: Tornatinidae
- Family Gastropteridae Swainson, 1840
- Family Philinidae "Clade 4"
- Family Philinoglossidae Hertling, 1932
- Family Plusculidae Franc, 1968 - contains only one species. It has been considered as synonyms of Philinoglossidae Hertling, 1932 since 2010.[3])
- Family Retusidae
2017 Taxonomy
According to the 2017 Taxonomy, Retusidae no longer belongs to Cephalaspidean and Cylichnidae is promoted to Cylichnoidea.[4] In additional to the re-established Scaphandridae and Laonidae, as well as the three new families established in 2015 by Oskars, Bouchet & Malaquias,[5] the nine families of Philinoidea As of 19 February 2018 are as follows:
- Family Aglajidae Pilsbry, 1895 (1847)
- Family Alacuppidae Oskars, Bouchet & Malaquias, 2015[5]
- Family Colpodaspididae Oskars, Bouchet & Malaquias, 2015[5]
- Family Gastropteridae Swainson, 1840
- Family Laonidae Pruvot-Fol, 1954[5]
- Family Philinidae Gray, 1850 (1815)
- Family Philinoglossidae Hertling, 1932
- Family Philinorbidae Oskars, Bouchet & Malaquias, 2015[5]
- Family Scaphandridae G.O. Sars, 1878[5]
