Classification of the Slender Walker


Domain - Eukarya

Eukarya have Eukaryotic cells and are divided into four sub units which include the Protista Kingdom, Fungi Kingdom, Plantae Kingdom, Monera Kingdom and finally the one which the Slender Walker falls into the Animalia Kingdom.

Kingdom - Animalia

Members of the Animalia Kingdom are either multi or unicellular and do not have a cells walls or choloroplast.  Other examples include humans, horses, dogs, giraffes, etc.                       


Phylum - Mollusca

The Phylum Mollusca has bilateral symmetry, more than two cell layers, a gut with a mouth and anus, open circulatory system, and in general they live in most enviroments.  Although for more information on environment of Pomatiopsis lapidaria please check out the Habitat page!


Class - Gastropoda

The class Gastropoda include the snails, slugs, and other slimy animals.  They make up a major part of the Phylum Mollusca.  Most members of this class have a shell and some can do what's called "torsion" with their shell.


Order - Mesogastropoda

 The Order Mesogastropoda includes both the land and sea snails.  They also are single gilled and are structurally diverse.  They can then be subdivided into many other families.  


Family - Pomatiopsidae

The family Pomatiopsidae is a small family containing freshwater snails.  They contain a shell and have gills and an operculum. 


Genus - Pomatiopsis

The Genus Pomatiopsis is generally found only in the United States and is subdivided into only a handful of species.


Species - Pomatiopsis lapidaria

The species Pomatiopsis lapidaria is a species that not nearly enough is known about it.   But we do know that they are a darker brown snail that is approximately 6-8mm long.  It is on the endangered species list so we need to protect it and take as much care of it as possible.  Hopefully with  more research we will be able to open many new doors and find out much more information about this incredible species. 





   Pomatiopsis lapidaria


*Land snails are a very understudied species and as more time and funding is available the more we will learn about them.
