Giant Worm Shells

The Giant Worm Shell, Vermetus gigas, is an irregularly shaped tube with just a hint of the spiral coil common to other sea snails. Worm Shells can be white, yellow, brown and pinkish in color. Because of the way they twist back on themselves it's difficult to measure their lengths, but the ones pictured all have a diameter of around 1.5 cm across. Photograph © James Prineas, 2003
