Unlike some related forms, the visceral mass is not sharply set off from the rest of the body. Taxonomy According to the latest taxonomy, the following families are recognised in the Superfamily Philinoidea: * Aglajidae * Alacuppidae * Antarctophilinidae Moles, Avila & Malaquias, 2019 * Colpodaspididae * Gastropteridae * Laonidae * Philinidae * Philinoglossidae * Philinorbidae ** '' Philinorbis'' Habe, 1950 ** '' Pseudophiline'' Habe, 1976 * Scaphandridae Scaphandridae is a family of sea snails, marine gastropod mollusks in th ...

Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=848158 on 2021-06-17 though Laonidae and Philinoidea are genetically distinct. They are monophyletic, meaning they are developed from a single ancestor. Laonidae also has the synonymised name Laoninae, which is largely unaccepted in the modern day scientific community. The name Laoninae is introduced by Alice Pruvot-Fol who proposes it as the subfamily to the genea Loana, A.Adams 1865.

Cephalaspidea
The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia.Jörger K. M., Stöger I., Kano Y., Fukuda H., Knebelsberger T. & Schrödl M. (2010). "On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia". ''BMC Evolutionary Biology'' 10: 323. . Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. This clade contains more than 600 species. Members of this worldwide clade used to be considered the most primitive of the opisthobranchs, but now they are considered as derived and specialized members of the Euthyneura Spengel, 1881. Headshield slugs are the most morphologically diverse group of all the opisthobranchs. Anatomy The vast majority possess a shell, although it may be reduced or internal. They have ...

Scaphandridae
Scaphandridae is a family of sea snails, marine gastropod mollusks in the superfamily Philinoidea. Taxonomy Scaphandridae was considered as a synonym of Cylichnidae in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). However, Malaquias et al. (2009)Malaquias M. A. E., Dodds J.

Gastropteridae
Gastropteridae, the bat-winged slugs, is a family of sea slugs, gastropod molluscs in the superfamily Philinoidea of the clade Cephalaspidea, the headshield slugs and bubble snails. The greatest diversity of these colourful small slugs is in the tropical and sub-tropical Indo-Pacific region. Description Gastropteridae is a fairly diverse family containing four genera and thirty-three described species. Adults have an internal reduced shell or no shell at all. The body is fairly short, usually under in length, but exceptionally up to . Compared to the closely related philinids and the aglajids, the mantle cavity is small, and the gills are located further forward, in an exposed position. In most species, the hind end of the headshield is narrowed, raised and curved forward, sometimes being further forward than the front edge of the head. A radula is present, but no jaws. These slugs are mostly brightly coloured and distinctively patterned. Gastropterids have parapodia (large ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelidonura Varians
''Chelidonura varians'' is a species of small sea slug, a marine opisthobranch gastropod mollusc in the order Cephalaspidea, the headshield slugs. Description & habitat This species has a maximum size of 70 mm. The background color is deep black. The margin of the parapod In invertebrates, the term parapodium ( Gr. ''para'', beyond or beside + ''podia'', feet; plural: parapodia) refers to lateral outgrowths or protrusions from the body. Parapodia are predominantly found in annelids, where they are paired, unjointed ...s and body are marked with a thin electric blue line. The two rather long "tails" at the end of the animal are characteristic of the genus ''Chelidonura'', the left one is always longer. They have also well-developed sensory cilia on the anterior edge of the head which are used to find their prey. This species lives on reef areas in shallow water lagoons with sandy or muddy bottom until 30 m depth. Distribution This cephalaspidean is widespread i ...

Euopisthobranchia
Euopisthobranchia is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura. This clade was established as a new taxon by Jörger et al. in October 2010. Euopisthobranchia is a monophyletic portion of the Opisthobranchia as that taxon was traditionally defined but is not a replacement name for that group as several marine opisthobranch orders including Nudibranchia, Sacoglossa and Acochlidiacea are not included. Euopisthobranchia consist of the following taxa: * Umbraculoidea * Anaspidea * Runcinacea * Pteropoda * Cephalaspidea s.s. Gizzard Previous studies discussed the gizzard (i.e. a muscular oesophageal crop lined with cuticula) with gizzard plates as homologous apomorphic structures supporting a clade composed of Cephalaspidea s.s., Pteropoda and Anaspidea. A gizzard with gizzard plates probably originated in herbivorous taxa in which it worked like a grinding mill, thus might be secondarily reduced in carnivorous groups within ...
