Aliculastrum cylindricus (Helbling, 1779)
15mm (shell)

This species is known mostly from empty shells, which are common at Kwajalein and Enewetak. If identified correctly, Kwajalein specimens are lighter in color than those found living in darker sand in the western Pacific. Living ones are occasionally found in sand or on rubble on lagoon reefs and sandspits. The living animal below was found and photographed by Christina Sylvester off Kwajalein's Emon Beach at a depth of about 2m. The shell measured about 15mm.

The one below was photographed at Enewetak Atoll.

An empty shell from lagoon sand at about 8m depth.
