Laonidae
Laonidae is a family of small marine snails belonging to the superfamily Philinoidea Philinoidea is a taxonomic superfamily of sea slugs, specifically headshield slugs, marine gastropod mollusks in the order Cephalaspidea. MolluscaBase eds. (2021). MolluscaBase. Philinoidea Gray, 1850 (1815). Accessed through: World Register of ...,MolluscaBase eds. (2021). MolluscaBase. Laonidae Pruvot-Fol, 1954. 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.

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 ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...
