Laevipilina antarctica explained

Laevipilina antarctica is a species of monoplacophoran, a superficially limpet-like marine mollusk.^[1] It is found in the Weddell Sea and the Lazarev Sea of Antarctica.^[2]

Evolution

In 2006, a molecular study on Laevipilina antarctica suggested that extant Monoplacophora and Polyplacophora form a well-supported clade with the researched Neopilina closest to the chitons.^[3] The two classes in this new clade, with the proposed name Serialia, all show a variable number of serially repeated gills and eight sets of dorsoventral pedal retractor muscles.
