Shell of the Week: The Antillean Caecum

Giving continuation to local species of the family Caecidae, today I present the Antillean Caecum, Caecum antillarum Carpenter, 1858. The small, curved, tube-like shell in this species is smooth, glossy in well-preserved specimens, and measures only up to 3.5 mm (about 0.14 inch). The structure opposite the aperture (shell opening), called the apical plug, is dome-shaped, hemispheric; shell color is white. The shell in the image was collected in 1998 by Lois Dunnam, at Gulfside City Park on Sanibel.
