Neodrillia cydia

Neodrillia cydia is a small, predatory sea snail known for its robust, high-spired shell. The shell typically ranges from 10 mm to 22 mm in length, with an average size around 13.7 mm. This species is distinguishable from similar ones by its stout shape, prominent spiral threads, and a notched anal sinus. While it resembles all-white Fenimorea species in both size and form, it stands apart due to its fewer ribs, more rounded whorl shoulders, and coarser surface texture.

This species occurs in the Western Atlantic Ocean of North Carolina, in the Caribbean Sea of Panama and Jamaica, and in the waters around the Lesser Antilles (Antigua, Barbados, St. Thomas).
