Classification
Domain:
Eukarya
Kingdom: Animalia
Phylum: Mollusca
Class: Gastropoda
Subclass: Pulmonata
Order: Stylommatophora
Genus: Daedalochila
Species: hippocrepis
Domain: The domain Eukarya is defined by the having eukaryotic cells that are membrane-bound and possessing a nucleus. Eukaryotes are multicellular have the ability to form tissues (Keeling, 2004).
Kingdom: Kingdom Animalia or Metazoa is characteristically heterotrophic, meaning they depend on other organisms for food. Most Metazoans have an internal cavity for digesting food. Unlike plants, animal cells do not have rigid cell walls and are comprised into specialized tissues (Meyers, 2001).
Phylum: The phylum Mollusca contains organisms that have a coelom, or true body cavity. They have a bilateral body and are triploblastic meaning it consists of three germ layers: ectoderm, mesoderm and endoderm. Mollusks possess a mantle, visceral mass and a muscular foot. (Biology Online, 2005).
Class: Class Gastropoda is characterized by having a shell in which the body can withdraw into. Gastropods have a head with two pairs of tentacles and a muscular foot used for movement. Gastropods are dioecious (Myers, 2001).
Subclass: The Pulmonates include organisms that are air breathing. They have reduced gills and their mantle cavity becomes a lung for breathing oxygen. (Thorp, 2011),
Order: The order Stylommatophora is defined by having a long pedal gland and two pairs of retractile tentacles. Almost all are terrestrial, and rarely lack a shell (Encyclopedia of Life, 2012).
Family: Polygyridae is characterized by ribbed jaws and a singular band of muscles that allow retraction of eyes and pharynx (Encyclopedia of Life, 2012).
Genus: The genus Daedalochila include organisms very small in size, recognized by their convoluted apertures with narrow openings (Encyclopedia of Life, 2012).
Species: The species hippocrepis is a terrestrial snail that is endemic to Texas (Encyclopedia of Life, 2012).
