Scaphander punctostriatus, common name the giant canoe bubble, is a species of sea snail, a marine opisthobranch gastropod mollusk in the family Scaphandridae, the canoe bubbles.[1]
The length of the shell varies between 30 mm and 40 mm.[2]
The shell is elongate, thin, and somewhat bubble-like, with a fragile structure. There is no evident spire, as the body whorl expands rapidly, covering the earlier whorls. The surface appears smooth but, under a microscope, reveals fine spiral lines of tiny, elongated pits (punctations). The aperture is elongated and very broad at the base. The animal is large and cannot fully retract into the shell.[2]
The shell is whitish, covered by a thin yellowish periostracum, and occasionally displays faint, darker spiral bands. The animal itself is yellowish-white.[2]
