Architectonica Perspectiva
''Architectonica perspectiva'', whose common name is the clear or perspective sundial shell, is a species of sea snail, a marine (ocean), marine gastropod mollusk in the family Architectonicidae, which are known as the staircase shells or sundials. Description and habitat The snails have a shell 5 to 7 centimeters in diameter. The cone-like shell coils up from a flat base. The spirals are composed of vibrant shades of black, white, and brown. The body and its tentacles are stripped as well to match the shell. Its Operculum (gastropod), operculum is made of a horn-like material. The snail is common in Indo-Pacific Asia and around India. The snail often lives among coral reefs, and enjoys sandy seafloors. References External links

Heterobranchia
Heterobranchia, the ''heterobranchs'' (meaning "different-gilled snails"), is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks. Heterobranchia is one of the main clades of gastropods. Currently Heterobranchia comprises three informal groups: the lower heterobranchs, the opisthobranchs and the pulmonates.Bouchet P. & Rocroi J.-P. (Ed.); Frýda J., Hausdorf B., Ponder W., Valdes A. & Warén A. 2005. ''Classification and nomenclator of gastropod families''. Malacologia: International Journal of Malacology, 47(1-2). ConchBooks: Hackenheim, Germany. . . 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278 Diversity The three subdivisions of this large clade are quite diverse: * The Lower Heterobranchia includes shelled marine and freshwater species. * Opisthobranchia are almost all marine species, some shelled and some not. The internal organs of the opisthobranchs have undergone detorsion (unwinding of the visc ...

Lower Heterobranchia
Lower Heterobranchia, also known as the Allogastropoda, is a group of rather specialized, highly evolved sea slugs and sea snails, ( marine gastropod mollusks) within the subclass Heterobranchia. WoRMS (2020). "Lower Heterobranchia". Accessed at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=1054700 on 2020-05-16 Although the great majority of Lower Heterobranchs are indeed marine, a few have succeeded in making the transition to freshwater. Description The shell shapes in this group are typically those that are seen in the sundial, pyramid, rissoella and orbitestellid families of snails. Taxonomy 2005 taxonomy In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, the Lower Heterobranchia is an Informal Group. Superfamilies within the Lower Heterobranchia include: *Unassigned to a superfamily (orbitestellid-shells) ** Family Cimidae ** † Family Dolomitellidae ** † Family Heterosubulitidae ** † Family Kuskokwimiidae ** † Family Misurinellid ...
