Otostila

Otostila is a genus of operculate land snails belonging to the family Odontostomidae. These snails are characterized by their distinctive shells, which typically have a high spire and a noticeable aperture. The operculum, a hard lid that seals the shell opening, is a key feature of this genus. Otostila snails are found in South America, particularly in regions of Brazil and neighboring countries. They inhabit a variety of environments, including forests and savannas, where they feed on decaying organic matter and algae. The genus was first described by Albers in 1860. Research on Otostila species often focuses on their shell morphology, reproductive biology, and ecological roles. The specific habitat preferences and distribution patterns of individual Otostila species can vary, contributing to the biodiversity of their respective ecosystems. Conservation efforts may be necessary for some species due to habitat loss and other environmental pressures.
