Pectinodontidae
Pectinodontidae is a family of sea snails or true limpets, marine gastropod mollusks in the superfamily Lottioidea, the true limpets. Lottioidea Taxonomy This family was previously ranked as subfamily Pectinodontinae (also with Acmaeinae and Rhodopetalinae) in the family Acmeaidae in the taxonomy of the Gastropoda by Bouchet & Rocroi (2005). Nakano & Ozawa (2007) elevated Pectinodontinae to family level Pectinodontidae based on molecular phylogeny research. A cladogram showing phylogenic relations of Patellogastropoda: Genera Genera in the family Pectinodontidae include: * '' Bathyacmaea'' * '' Bathyacmaea secunda'' Okutani, Fujikura & Sasaki, 1993 *'' Pectinodonta'' - the earliest known ''Pectinodonta'' are from Late Oligocene The Chattian is, in the geologic timescale, the younger of two ages or upper of two stages of the Oligocene Epoch/ Series. It spans the time between . The Chattian is preceded by the Rupelian and is followed by the Aquitanian (the lowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patellogastropoda
The Patellogastropoda, common name true limpets and historically called the Docoglossa, are members of a major phylogenetic group of marine gastropods, treated by experts either as a clade or as a taxonomic order. The clade Patellogastropoda is deemed monophyletic based on phylogenetic analysis. Taxonomy Patellogastropoda was proposed by David R. Lindberg, 1986, as an order, and was later included in the subclass Eogastropoda Ponder & Lindberg, 1996. 2005 taxonomy Bouchet & Rocroi, 2005 designated Patellogastropoda, true limpets, as a clade, rather than as a taxon, but within included superfamilies and families as listed below. Families that are exclusively fossil are indicated with a dagger †: *Superfamily Patelloidea **Family Patellidae *Superfamily Nacelloidea **Family Nacellidae *Superfamily Lottioidea **Family Lottiidae **Family Acmaeidae Forbes, 1850 ***subfamily Acmaeinae Forbes, 1850 ***subfamily Pectinodontinae Pilsbry, 1891 ***subfamily Rhodopetalinae Lindber ...

Bathyacmaea Secunda
''Bathyacmaea secunda'' is a species of very small (adults are typically about 6 mm in length), deep-sea true limpet, limpet, a marine (ocean), marine gastropod mollusk in the family Pectinodontidae. This species inhabits the dark, chemosynthesis-based marine vent community, communities of ocean vents and cold seeps near Japan (e.g. the Okinawa Trough). It is distinct from other true limpets in the following ways, among others: its intestine runs through its Ventricle (heart), ventricle, it has a pair of radular "teeth" with long shafts, and its statocysts are isolated from the pleural ganglia and pedal ganglia. It also has a ctenidium (mollusc), ctenidium rather than the usual set of circumpallial gills, lacks osphradium, osphradia, and does not have even rudimentary eyes. For these reasons, along with a comparison of the development of the shell at the microscopic level, it has been argued that ''B. secunda'' is not closely related to the Patelloidea or the Neolepetopsida ...
