Inversionella

Inversionella is a genus of marine snails belonging to the family Buccinidae. These gastropod mollusks are characterized by their generally ovate or fusiform shells, which often exhibit distinct axial sculpture and sometimes spiral ornamentation. The aperture of inversionella is typically elongated and may possess a noticeable siphonal canal. The operculum, a calcareous plate that seals the shell opening, is usually corneous and paucispiral.

Species within the genus inversionella are found in various marine environments, primarily in temperate and subtropical waters. Their distribution is often associated with benthic habitats, where they may inhabit sandy substrates, muddy bottoms, or rocky areas. The diet of these snails is generally carnivorous, with many species preying on other invertebrates such as polychaete worms or smaller mollusks. Reproduction in inversionella follows the typical pattern for marine gastropods, involving external fertilization and the release of planktonic larvae or the deposition of egg capsules.

The taxonomy of inversionella has been subject to revision as new morphological and molecular data become available. Several species have been described under this genus, though their precise phylogenetic relationships are still a subject of ongoing research. Understanding the ecology and evolution of inversionella contributes to our broader knowledge of marine gastropod diversity and the functioning of benthic ecosystems.
