Triodopsis tridentata is a northern terrestrial snail that can be found in woodland and rocky areas (Nekola, 2009). The specific type of woodland area Triodopsis tridentata lives in is a mesic forest, which has plenty of water supply for the snail to survive (Nekola, 2009). This type of habitat makes the Northern United States a perfect place for a Northern Threetooth to inhabit. This snail has been distributed through 23 states in the U.S. and two provinces in Canada such as Wisconsin, Michigan, Illinois, Pennsylvania, and Ontario (Nekola, 2009). Triodopsis tridentata  has also been found in southern states such as Alabama, Mississippi, and Tennessee (NatureServe, 2011).
