Amphinomia

Amphinomia is a genus of sea snails, marine gastropod mollusks belonging to the family Buccinidae. These snails are characterized by their elongated, fusiform shells, which are often sculptured with axial ribs and spiral cords. The aperture of the shell is typically ovate, with a short, open siphonal canal. The operculum is horny and ovate.

Species within the genus Amphinomia are found in various marine environments, primarily in the Indo-Pacific region. They are often benthic, inhabiting soft substrates like sand and mud, as well as rocky areas. Their diet consists mainly of other invertebrates, and they are predatory in nature.

The genus was first described by Constantine Samuel Rafinesque in 1815. While not as widely known as some other marine gastropod genera, Amphinomia holds ecological significance within its habitat. Research on this genus contributes to our understanding of marine biodiversity and the ecological roles of predatory sea snails. Further study is ongoing to fully delineate species boundaries and understand their evolutionary relationships within the Buccinidae family.
