Alvania subcalathus is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.[1]
Description
The shell of A. subcalathus measures between 2.5 mm and 4.3 mm in length. It exhibits the typical rissoid morphology: a small, turriform shell with spiral and axial sculpture visible under magnification, often displaying a glossy, pale-colored surface.[2]
Distribution
This species is found in the northeastern Atlantic Ocean, particularly around the Canary Islands and the Savage Islands. Reports indicate it occurs in subtidal zones, generally at depths down to around 12–20 meters.[3]
