editAlvania nicolauensis is a grazer who feeds on detritus on the ocean floor.[3] Specimens are usually brown or white in color. The shell has four large whorls taking up most of its size. It has a small parietal wall. There is a crossed pattern of indentations across the shell, giving it a textured look.[4] The shell length can be up to 2.7mm.[5]
