Habitat
The Tulsa Whitelip is found only in the United States (DiscoverLife). Even within that large region, its habitat is only within the state of Oklahoma (Encylopedia of Life).
Oklahoma is a state with mostly flat plains and low hills (Netstate). Like other pulmonates, the Tulsa Whitelip is typically found in forests (Bourqin, 2000). The region where the Tulsa Whitelip is found is within the Red River Valley Region (Netstate). This region is along the Texas-Oklahoma state line (Netstate). The fertile soil of the region is a great spot for mating and for laying eggs (Tompa et al, 1984).
Another part of N. lioderma's habitat is its shell. The shell is coiled (has a spiral shape) so that locomotion is preserved (Gillis, 2012). If the shell wasn't coiled, the shell would be become too long and impede locomotion (Gillis, 2012). As most snails have, the Tulsa Whitelip also has an operculum. The operculum is a tough, spiny plate (Gillis, 2012). In the event of a predator attacking, snails can retract their body into the shell and seal the entrance with their operculum (Gillis, 2012).
