The egg-shaped, inflated, rather thin-shelled snail shell of Natica hebraea , which in adult snails can be up to 4.5 to 5.5 cm in length and up to 5.1 cm in diameter, has a smooth, shiny surface, with the seam oblique radial furrows. The umbilical bulge is large and separated from the ingrown, thickened part of the inner lip by a narrow incision at the top. The case mouth has a columellar rim and is dark brown inside. The basic color is whitish, but becomes bluish towards the tip and darker and darker, finally black. Dark brown welts, interrupted by narrow whitish transverse bands, run parallel to the growth strips. A narrow, milky white band runs along the seam. The umbilical region and inner lip are white, the adjoining brown welts appear as square spots.
