Classification found from Encyclopedia
of Life.
Domain: Eukaryotes are defined by having a membrane bound nucleus that contains genetic material, which Prokaryota does not categorize with (Hickman, 2009).
Kingdom: Animals are defined to lack a cell wall, be multicellular, and heterotrophic (Global Biodiversity Information Facility 2007). Most animals digest their food in an internal organ and nearly all animals undergo sexual reproduction (Global Biodiversity Information Facility 2007).
Phylum: Molluscs have a muscular foot on the underside of its body, a radula with many chitinous teeth, and a mantle with a cavity used for breathing and excretion (Global Biodiversity Information Facility 2007).
Class: The defining process of Gastropods is undergoing torsion, where the visceral mass rotates 180 degrees during development (Global Biodiversity Information Facility 2007). Gastropods also have a ventral foot and a well-defined head with two or four pairs of sensory tentacles (Global Biodiversity Information Facility 2007).
Order: Stylommatophora consists of air-breathing land snails and slugs which use their mantle as an air breathing lung (Global Biodiversity Information Facility 2007).
Family: Polygyridae are distinguished from other gastropods because they lack a dart apparatus, have ribbed jaws, and retractable tentacles which are connected with one united muscle (Global Biodiversity Information Facility 2007).
Genus: Triodopsis are air breathing snails and contain flat spiraled shells (Global Biodiversity Information Facility 2007).
Species: The scientific name tridentata means "trident" or three which gives the Northern Threetooth its common name because it has three teeth (Global Biodiversity Information Facility 2007).
The common name for Triodopsis tridentata is Northern Threetooth which comes from the English meaning of the species name.
Encyclopedia of Life has many organism classifications which were used for Triodopsis tridentata.
