Mammilileen

Mammilileen is a genus of small, terrestrial gastropod mollusks in the family Charopidae. The genus was first described by the French zoologist Jean-Baptiste Lamarck in 1822. The name "Mammilileen" is derived from the Latin words "mammilla," meaning small nipple-like protuberance, and "ileum," referring to the ileum, a part of the small intestine. This name reflects the distinctive nipple-like structures found on the shell of these snails.

Mammilileen species are characterized by their small, conical shells with a smooth or slightly sculptured surface. The shells are typically light brown or gray in color and can reach up to 2.5 millimeters in height. The genus is found in various habitats, including forests, grasslands, and agricultural areas. They are known to feed on decaying plant material and other organic matter.

The genus Mammilileen includes several species, with the most well-known being Mammilileen mammilium. This species is native to Europe and has been introduced to North America. It is considered an invasive species in some regions, as it can outcompete native species for resources and alter local ecosystems.

Mammilileen species play a role in the decomposition of organic matter, contributing to nutrient cycling in their environments. However, their invasive nature and potential impact on native biodiversity have led to efforts to control and manage their populations in certain areas. Ongoing research continues to shed light on the ecology and behavior of these small gastropods.
