Tulebididae

Tulebididae is a family of small to medium-sized, mostly terrestrial snails, terrestrial pulmonate gastropod mollusks in the superfamily Orthalicoidea. The family was first described by the German malacologist Friedrich von Martens in 1860. The family is native to the Americas, with the majority of species found in the western United States and Mexico. Tulebididae is characterized by its smooth, rounded shells with a low spire and a wide aperture. The family includes around 20 species, with the most well-known being Tulebia californica, which is found in the western United States and Mexico. The family is of interest to malacologists due to its unique shell morphology and the ecological roles its members play in their respective ecosystems.
