The last part of the species name, smithi, means that the species was named after the person who discovered it, Smith.

The common name simply arose from the state it is most commonly found in, Alabama. Shagreen is a word for untanned leather that has a rough surface texture, which the shell of the Inflectarius smithi is similar to. To see the definitions for shagreen, go to

How Inflectarius smithi fits into these categories...
Eukarya: Cells are more complex and structurally organized than those of Archaea and Eubacteria (Encyclopedia of Life, 2012). Organelles are bound by membranes, and the nucleus is membrane bound (EOL, 2012). The name ‘eu-karyote’ means ‘true kernel’, referring to the membrane bound nucleus that the Archaea and Eubacteria groups lack (EOL, 2012).

Animalia: Multicellular organisms that lack cell walls that the Kingdom Plantae has (EOL, 2012). They are heterotrophic, meaning they have to find their own food instead of producing their own food, such as plants do through photosynthesis (EOL, 2012). Their locomotion is through muscles bound to the skeletal system, tissues and nerves (EOL, 2012). Most of the Kingdom Animalia reproduce sexually, but there are a select few that do asexual reproduction (EOL, 2012).

Mollusca: This Phylum is well known for their muscular foot, which can be used for locomotion, attaching to surfaces, digging/burrowing, anchoring, swimming and grasping (EOL, 2012). Because of all these various forms of the muscular foot, it produces the great variety seen in the Mollusca Phylum (EOL, 2012). They have a layer of epidermal tissue called the mantle that helps to form the shell that most of these animal have (EOL, 2012). Their habitats range from freshwater, moist terrestrial areas, and marine waters (EOL, 2012).

Gastropoda: This class contains the snails and slugs, where they either have the spiraled shell or not (EOL, 2012). Torsion takes place in this class during the larval stage, where the body is twisted to place the anus near the mouth, making it so they only have one opening to close when being attacked by predators (EOL, 2012). Gastropods use their muscular foot to slowly creep along, in some it is modified for swimming or digging (EOL, 2012). Sexually, this Class can either self fertilize (dioecious) or exchange sperm bundles or engage in copulation (hermaphroditic) (EOL, 2012).

Stylommatophora: Terrestrial Gastropods that have two pairs of tentacles that can be retracted inwards; the uppermost pair contain the eyes at the end (EOL, 2012). Most of the animals in this order have shells, but some do not possess any (EOL, 2012).

Polygyridae: This family is made up of air-breathing land snails that are easily found in eastern and western North America, northern Central America and also the Caribbean Islands (EOL, 2012).

Inflectarius: This genus contains air-breathing lands snails that are located mainly in the eastern part of North America (BOLDsystems, 2012). As one can see in the picture to the right of the Inflectarius smithi shell, they are of a relatively small size and the whorls of its shell are rather flattened. The opening to the shell is small, due to the large sizes of the lip and teeth of the shell.
