Scaphander

Scaphander is a genus of sea snails, marine gastropod molluscs in the family Scaphandridae, the canoe bubbles.

[1] (Described as Meloscaphander) The shell is ovate, convex in its upper part, and tapers below, with a low, slightly exserted spire.

The aperture is large but shorter than the shell, and the columella is moderately curved and thick.

[2] (Described as Scaphander (Sabatina) ) In most, if not all, species of this proposed subgenus, the callosity on the body does not form a distinct "fold."

These species possess an animal capable of fully retracting into the shell, with gastroliths identical to those found in Scaphander lignarius.
